ATM/WAN Testing Made Easy

To install or troubleshoot an ATM or WAN link, it is necessary to test for many things: physical errors, equipment interoperability, ATM cell congestion, and even LAN traffic problems. The Agilent Advisor offers integrated ATM, WAN, and LAN protocol analysis capabilities, along with bit error ratio testing (BERT), stimulus/response measurements, and statistical analysis capability everything required to get a good look at the physical layer, ATM/MAC layer, and all of the upper protocol layers.

In addition, the Agilent Advisor can test ATM quality of service (QoS) with contract conformant traffic and can check live traffic for conformance to a traffic contract (policing). For Frame Relay, the Agilent Advisor can verify that Service Level Agreements are met.

No matter what the traffic level, the Agilent Advisor will capture every cell or frame on full-duplex network connections. It monitors non-intrusively and decodes ATM or WAN data at full line rate. Further, it can simulate traffic from either direction within a connection. In addition, it can process previously captured data from its capture buffers or from a file for retransmission. The analyzer not only captures traffic when the network is working - it provides information when the network is broken - when it is needed the most.

LAN over WAN, and LAN (over WAN) over ATM

Encapsulated LAN data is automatically extracted and decoded by the Agilent Advisor including complex encapsulated protocols. For unique encapsulation schemes, the user may specify the offset as well. Nearly 300 decodes exist for layer 3 and above; these are common to all underlying technologies (LAN, WAN and ATM).

The Agilent Advisor provides an off-line LAN Expert Analysis tool. The off-line LAN Expert Analysis allows the user to examine Ethernet, Fast Ethernet, Gigabit Ethernet, ATM or WAN (HDLC or Frame Relay) encapsulated LAN frames on an Agilent Advisor or personal PC without Agilent Advisor hardware.

The comprehensive set of protocol decodes include all of todays popular Protocol Stacks:

 TCP/IP  SUN  AppleTalk  XNS  Banyan  Cisco  DECnet  3Com  IBM/SNA  H.323 series, T.38  Novell  SIP, MGCP,SGCP, MEGACO  ISO  W-CDMA

Commentators

Powerful Commentators follow state-based protocols and can provide warnings and alerts when unusual message sequences are detected.

Real-time Filtering

The Agilent Advisor now offers real-time IP and WAN filtering at rates up to 155Mb/s. This allows the user to isolate and analyze LAN and Frame Relay traffic taking place on an ATM circuit or LAN traffic taking place on a Frame Relay circuit.

The real time filtering function gives users application-level, LAN-centric troubleshooting on their ATM or Frame Relay network, thus allowing them to observe specific traffic types for potential problems on the network. The user can even filter by IP source and/or destination address. IP traffic encapsulated in Frame Relay that is additionally encapsulated over ATM can also be analyzed. This feature maximizes valuable buffer space for optimal data collection of targeted LAN traffic since the filtering takes place before data capture.

In addition to capture filtering performed in hardware, the Agilent Advisor is able to gather counts of events such as cells or frames within the defined criteria of the filters. Powerful display (post-capture) filtering and search functionality allows the user to drill down further for troubleshooting purposes.

For more details concerning these features, refer to the corresponding technical sections within this document.

Enhanced decode view

The decode view is user configurable by right clicking in the summary view. The decode view has a very user-friendly, one-line and multi-line read out in the summary view. Also, the decode view offers hex to detail mapping by highlighting an element in the detailed view, the corresponding hex element is highlighted in color in the Hex section of the decodes. The reverse is also true.

The Agilent Advisor also has powerful, user-configurable 100ns resolution timestamp options as follows:

 Delta  shows the time interval between adjacent cells or displayed filtered

frames.

 Relative  shows the time difference between critical events and other cells in

the traffic flow; for example, if a ping is considered time-zero, cells which arrived before or after will be time-stamped with their relative corresponding arrival time.

 Absolute  displays events with date and time with a resolution of 100

nanoseconds.

Color mapping of the protocol layers in the decode view distinguishes each of the layers in the data flow for easy identification, thus simplifying protocol analysis.

Acquisition Systems

There are two acquisition systems for ATM and WAN: the J2300E Agilent Advisor mainframe and the J2900A High Speed undercradle.

J2300E Agilent Advisor Mainframe

The J2300E mainframe comprises the acquisition system for all ATM and WAN plug-in modules plus the V series interfaces, connectors for which are present on the body of the mainframe. For LAN measurements such as Ethernet 10/100/ 1000, Token Ring and FDDI, LAN undercradles can be attached to the J2300E.

In addition, the mainframe includes a full PC running the Microsoft Windows98® operating system on a 400 MHz processor, 256 MB of RAM, a built in keyboard with pointing device, a Super VGA active color display, dual PCMCIA card slots, stereo speakers and the usual printer and serial ports. The PC is used to control the mainframe acquisition system and the acquisition system in any attached undercradle, and to collect and post process results.

With the new 400MHz PC processor and larger momory, post capture filtering and searches are significantly faster than before, saving valuable troubleshooting time.

Note that the PC is not used for real-time processing of measurements  this is all done in the acquisition system and plug-in modules. This allows the PC to handle multiple tasks such as the Dual Simultaneous Analysis feature which involves the simultaneous control of the mainframe acquisition system and attached undercradles, as discussed later.

J2900A High Speed Undercradle

The J2900A undercradle is similar in function to the J2300E mainframe except that it has no built in PC but relies upon the PC contained in the J2300E ATM/ WAN or J3446E LAN mainframes to control it and to collect and post process results. It accepts all ATM and WAN plug-in modules.

Dual Simultaneous Analysis

The Agilent Advisor has the ability to test at two different interfaces and technologies simultaneously, e.g. E1 Frame Relay and E3 ATM, DS3 Frame Relay and 10/100 Mb/s Ethernet, ATM25 and OC-3 ATM, etc. This functionality allows the user to test interworking in mixed technology environments (see the Application Note 1346 for details on this kind of testing).

In order to perform dual simultaneous analysis, combinations of an Agilent Advisor mainframe (J2300E or J3446E) and an undercradle (J3444A or J2900A) is required, the mainframe and undercradle being each supported by an application (LAN, WAN or ATM) running on the PC embedded in the mainframe. Note that the applications do not have to be different so, for example, a J2300E Agilent Advisor mainframe fitted with a J2900A High Speed undercradle could each be fitted with the same type of ATM or WAN interface and run simultaneously  e.g. two J3766A ATM25 interface modules.

The following table shows the combination of supported mainframes, undercradles, interfaces and technologies.

Table 1 Hardware Sup port

Note: The supported operating temperature range for Dual Simultaneous Analysis is 5° C to 30° C (41° F to 86° F).

-IFMP-C (RFC 1987)

-GSMP (RFC 1954)  Fore Switch Signaling: SPANS  ATM Forum MPOA  Newbridge VIVID (MPOA)

Simulation

The Agilent Advisor is able to simulate upper layer traffic either by the use of pre-defined messages, e.g. ATM encapsulated ICMP-echo (PING), through the development of user defined cell sequences. Or, more conveniently, by copying and pasting previously captured traffic to the cell table and editing it, as appropriate (see ATM Cell Generation in a later section).

The Agilent Advisor provides decodes for AAL-1 through AAL-5. Decodes are also included for AAL-2 Common Part Sublayer (AAL-2 CPS to ITU-T I.363.2) and AAL-2 Service Specific Segmentation and Reassembly sublayer (AAL-2 SSSAR to ITU-T I.366.1).

ATM Layer

Up to 1024 virtual channels are auto-detected on all ATM interfaces up to 155

Mb/s, except J2. For each auto-discovered virtual channel, the following

statistics are collected:

Maximum and instantaneous utilization (%)  Total cells and octets (count)  Maximum, instantateous and average throughput (kb/s)  Header (HEC) errors (count)  CLP status (0 or 1)

At the 622 Mb/s ATM interface, up to 4096 VCs are auto-discovered.

Data within the ATM layer is captured in a cell-based buffer. Capture of ATM

cells occurs at full line speed up to 622 Mb/s into a data buffer. Each cell is

stamped with a 100 ns resolution time stamp and at rates up to 155Mb/s. The

display is user customizable - absolute, relative to a specific event, or delta,

representing the time change from one cell to the next, and a field indicating

whether the HEC was erroneous.

Display filtering of cells can be based on any of the header fields and also on

many common types of embedded protocols. OAM cells can be monitored

exclusively or with other data traffic for detailed analysis. Selective capture

can be done using pre-written quick test scripts or user-defined capture filters.

ATM Testing (continued)

ATM Capturing, Filtering and Searching

Capture Filters and Counters

Hardware counters and filters allow the user to select cells or AAL5 PDUs to

bring into the capture buffer. Even on a lightly loaded network, at ATM speeds

it does not take long to fill a data capture buffer. With data filtering, the user

can zero in on exactly the data the user needs to see. The filters examine every

cell in real time as it appears on the network. Since the filtering is done in the

hardware, nothing is missed, and the performance of the measurements and

user interface are not compromised.

Up to twelve hardware filters and counters can be enabled simultaneously and,

additionally, any two of the filters can be enabled to capture all the cells that

contain AAL5 PDUs. Flexible and user assisted menus can be used to define

specific filters, counters, and triggers based on protocol headers (see figure 2).

Examples include ATM, LAN over ATM (to RFC 2684/1483), Frame Relay

(FRF.5), LAN over Frame Relay over ATM (to RFC 2427/1490 and FRF.5

simultaneously), and Classical IP and ARP over ATM (RFC 2225/1577). Filter and

counter criteria can be used to start/stop the data capture and to center the

data in the buffer, the user can see what led up to an event and what followed

it. Filter criteria may also be used to ignore or store the data.

Figure 2: ATM Filter/Counter Properties.

Filters are also used as counters to specify statistical measurements based upon any part of the ATM header or payload on the line (network) side, the equipment (user) side of the link, or both. The counter and filter results provide the following:

 Number of cells that met the filter criteria  Percentage of cells out of the total busy (assigned) cells on the line  Percentage of bandwidth these cells occupied  Throughput in kb/s of these cells  Throughput in cells per second of these cells

Whatever filters or connectors the user selects or creates, the results are automatically grouped in real time.

ATM Testing (continued)

The following filters are provided, but others are easily created to incorporate several variations. Specific interface configurations and traffic generation cell tables can be saved along with filter configurations:

 IP address filtering  ILMI filtering  OAM filtering  Protocol distribution filtering  VP.VC filtering

Display Filters and Searching

Display filtering and searching lets the user search through collected data to find specific IP addresses, values for protocol fields, or conversations on specific bi-directional virtual connections (by VPI-VCI). The display filters provide the flexibility to select protocol attributes or specific protocols from a checklist, and the power to filter on any bit, byte or characteristic, such as protocol. For example, filtering can be preformed on OAM traffic without having to know any of the protocol specifics.

Post-processing lets the user quickly zoom in on selected criteria, from the traffic passing between specific devices to individual conversations. Post-processing allows the user to:

 Search through the data by record or by time stamp  Search for events or strings  Filter on protocols  Verify event-to-event timing  View protocol errors  Print a range of cells or the entire buffer  Export data in CSV (comma separated variables) format  Analyze statistics based on the buffered data

ATM Cell Generation

An ATM cell editor can build a cell table of up to 255 user defined or previously captured cells that can then be transmitted onto the network. Editing functions include the following:

Add  Edit  Delete  Copy  Insert

Windows keyboard commands are also supported  Ctrl-c, Ctrl-v, Ctrl-x, etc. Sequences of captured cells (e.g. an AAL-5 PDU) can be copied and pasted to the cell table; the resulting cell table contents can be edited/modified (e.g. to change the VPI-VCI or to change embedded IP addresses) and the HEC and AAL-5 CRC recalculated, as appropriate, prior to transmission.

ATM Testing (continued)

During the time that the cell table is not being sent, the Agilent Advisor will send idle or unassigned cells. Send Control allows the contents of cell table to be sent once or repetitively, or for AIS or idle cells to be sent. The peak cell rate (PCR) of the cell table based traffic can be set from zero to the following maximum values, all of which are 100% utilization for that interface. Also, for ease of entry, a percent of utilization can be entered, such as 50% in place of the cells per second value.

 353,207 cells per second for STM-1/OC-3, STM-1e/EC-3 and UTP155  104,268 for DS3 HEC  96,000 cells per second for DS3 PLCP  80,000 for E3 HEC  72,000 for E3 PLCP  59,111 for ATM25 with X8 8kHz timing reference  59,259 for ATM25 without X8 8kHz timing reference  14,491 cells for J2  3,623 cells for DS1  4,528 cells for E1

To generate OAM cells, the user can use quick tests that include F4 and F5 segment or end-to-end cells with user-defined VPI[-VCI] values, they are transmitted from the traffic generator. To generate cell errors, modify the quick tests to add corrupted cells to the cell table.

The fields of the generated ATM cell header can be specified as follows:

 VPI values from 0 to 255 (UNI), or 0 to 4095 (NNI)  VCI values from 0 to 65,535  GFC values from 0 to 15 (UNI only, not applicable in NNI)  PTI values from 0 to 7  CLP values of 0 or 1  HEC can be set to good (automatically calculated), bad, or user defined.

The generated ATM cell payload can be defined in hex, decimal, ASCII, or dont care. Errors can be inserted on any bit within any byte of the payload.

ATM Quality of Service (QoS) and Policing Tests

The Agilent Advisor has the ability to do various real-time tests and measurements to check the performance of ATM networks. These fall into two main categories  policing and traffic contract shaped test cell generation, really mirror images of each other. In the case of policing, the Agilent Advisor monitors live traffic and measures conformance to the traffic contract. Test cell generation allows test traffic shaped to a traffic contract to measure the networks ability to deliver the promised QoS, i.e. is the network meeting its SLA (service level agreement) obligations?

Policing, traffic shaping and traffic contract measurements

One of the most important premises of the deployment of ATM networks is the ability to maintain a given level of QoS within the public ATM network. ATM networks protect themselves by policing incoming traffic to check its conformance with pre-determined traffic contract parameters. Some cells may have to be discarded or tagged (marked to low priority) in order to protect the traffic of other users of the ATM network.

ATM Testing (continued)

When customer traffic exceeds or violates its contracted peak cell rate (PCR), taking into account its cell delay variation tolerance (CDVT), cells may be discarded or tagged; when it exceeds the sustainable cell rate (SCR) parameters, taking into account its maximum burst size (MBS) allowances, cells may be discarded or tagged (cell loss priority (CLP) bit changed to 1), depending on the type of traffic contract. When congestion occurs in the core network, low priority cells (CLP = 1) are discarded first by core ATM switches before the cells of normal priority (CPL = 0). Policing enables networks to assure a consistent quality of service within the core network, preventing the overall network performance to be degraded by an individual user.

The Agilent Advisors policing measurement feature is a real time measurement that checks a virtual connections conformance to the traffic contract at the ingress to the public network; this could be a virtual channel connection or virtual path connection. The user specifies the traffic contract type (e.g. VBR.3/SBR3) and parameters (PCR, CDVT, SCR and MBS) for the virtual connection and the Agilent Advisor counts the non-conforming test cells and delivers a non-conformance count and non-conformance ratio for active traffic on the network. This measurement would be used typically to check a users traffic either side of the boundary to the public network when quality of service is suspect (the user experiences unexpected levels of cell loss). If the user traffic entering the network does not conform, the network cannot be blamed for the resulting poor QoS.

Traffic Contracts Supported

As shown in figure 3, the user may specify one of the following types of traffic contract to determine how many cells in the virtual connection are conforming or non-conforming:

Figure 3: Traffic Configuration.

Shaping of test cell traffic and background traffic

There are two sides to any contract and ATM traffic contracts are no exception.

If the user traffic keeps to its contract obligations then the network should

deliver the quality of service it guarantees in the traffic contract. This is usually

specified in terms of cell loss and added cell delay variation, etc.

The Agilent Advisor is able to measure ATM layer QoS by generating test traffic

shaped to meet the traffic contract in terms of PCR, CDVT, SCR and MBS; it

also allows users to choose the standardized Generic List values for the

parameters. The test traffic comprises test cells which conform to ITU-T

Recommendation O.191 which specifies the test cell and the methodology for

measuring ATM layer QoS parameters specified in ITU-T Recommendations

I.356 and I.357, and the ATM Forums Traffic Management Specification version

4.1. Measurements made by the Agilent Advisor are as follows:

Cell Loss Ratio

Cell Misinsertion Rate

Cell Error Ratio

Cell Delay Variation

Mean Cell Transfer Delay

Minimum Cell Transfer Delay

Maximum Cell Transfer Delay Severely Errored Cell Block Ratio Availability Ratio Transmitted Cells Non-Conforming Cells Tagged Cells

Test traffic can be sent and received by the same Advisor for local testing or it

can be sent by one Advisor and received on the other side of the network by

another. Each Agilent Advisor on either end of a connection, can source test

traffic in the opposite direction on the same bi-directional virtual connection

and, at the same time, analyze traffic from the other; each Advisor is configured

to source traffic conforming to the traffic contract for that direction of the

virtual connection; such connections are often asymmetrical. As conforming

test traffic is entering the network, any cell loss or cell delay variation detected

on the far side of the network must be caused by the network itself; this can be

compared with the SLA requirement to check that the network is complying

with its side of the agreement. The Advisor is also capable of generating same

link background traffic (on other virtual connections).

ATM Testing (continued)

For more details about policing and shaping, see the ATM QoS White Paper.

Test Cells

The ITU-T Recommendation O.191 specifies a test cell and a methodology for

using it to determine ATM QoS measurements, as defined in ITU-T

Recommendation I.356 and I.357. The ATM Forum references I.356 in its Traffic

Management 4.1 specification.

The O.191 test cell has a standard header for any user channel (any VCI above

31 is allowed). The payload has a number of special fields which allow the QoS

measurements to be made: there is a 32 bit sequence number field for

measurements of cell loss (ratio) and cell misinsertion (rate); there is a 32 bit

time stamp (with 10ns granularity in the least significant bit) for cell delay and

cell delay variation measurements, and the entire payload is error checked by a

CRC-16 for measurements of cell error. In addition, the entire payload is

scrambled to ensure that all bits of the payload are exercised so that memory-

based switch fabrics can be tested for stuck bits.

Because the O.191 test cell and the methodology for its use are standardized,

O.191 conformant test equipment from different vendors can inter-operate.

Results should be consistent between equipment from different vendors.

However, proprietary extensions are permitted, and Advisors working together

(one at each end of a virtual circuit) can detect when the network has tagged

(market to low priority, i.e. CLP = 1) a cell, which was sent at normal priority

(CLP = 0); these events are counted.

ATM Signaling and Call Placement

While permanent virtual circuits (PVCs) have dominated the ATM world thus

far, switched virtual circuits (SVCs) are increasing in utilization. Due to this

growth, it is necessary to have confidence in SVCs set up and troubleshooting

when the unexpected happens.

The Advisor includes UNI signaling emulation, ILMI address registration and

LANE emulation to provide connectivity testing. The signaling and call

placement feature supports ATM Forum UNI 3.0, 3.1 and 4.0. The Advisor can

emulate the user or network side of the UNI. In addition, the user can specify

and edit the information elements (IEs) placed on Call Connect messages that

specify what type of SVC to bring up. Figure 4 shows the configuration for call

signaling while figure 5 displays the results.

Physical Layer

Inverse Multiplexing for ATM (IMA)

The Advisor can now decode IMA Control Protocol cells. These ICP cells are sent regularly on each E1 or T1 in an IMA Link Group in order to manage the IMA process. The ability to decode and display these physical layer cells helps troubleshooters identify IMA configuration problems.

ATM Testing (continued)

Bit Error Ratio Testing (BERT)

Often problems on the network can be attributed to the transmission medium.

The Advisor has a powerful, built-in bit error ratio test capability that performs

not only frame-based BERT (SDH/SONET-level), but also cell-based BERT, in

which the bit patterns are carried in the payload of the ATM cell.

 User defined - one octet (8 bits)

Optical Power Measurements

In addition to full ATM analysis, the STM-1/OC-3 ATM interface has a built-in

optical power meter that allows the user to check power levels with an

accuracy of +/- 0.5 dBm. This measurement capability has the ability to be

performed using the same interface on an optical fiber carrying STM-4c/OC-12c,

even though the interface does not otherwise operate at 622Mb/s.

Signal Strength Pulse Amplitude Meter

In addition to full ATM analysis, the Agilent Advisor E1/T1 and E3/T3 cells and

frames interfaces and STM-1e/EC-3 ATM interfaces have a built-in pulse

amplitude signal strength power meter that allows users to check pulse

amplitude levels with a resolution of +/- 1 dBm. The dynamic range is between

+6 dBmV and 40 dBmV.

Line Status

The operation of the physical interface is often critical in determining the cause

of network problems. Therefore, the Advisor also tracks errors at the physical

layer. Counts of error and alarm events are recorded on the display for both

the line (network) and equipment (user) side. The time of the last occurrence

of a particular event is recorded as well. Events are saved in the buffer and can

be logged to disk.

Figure 6: Line Status.

Line status is displayed in real time and is shown in figure 6. All of the events listed below are saved in the buffer and counted in the line status display. These events may be logged to disk. The current status of critical parameters (marked with an asterisk (*)) is also displayed in large green or red boxes in the line status display, for easy, at-a-glance viewing.

WAN Testing

All major WAN interfaces, including V.10/V.11, V.24/V.28/RS-232C, V.35 and

V.36/ RS-449/422/423 are already built into the instrument mainframe; X.21

(with J2277A external cable  V.36/RS-449 to DB15) and RS-530 (with external

cable J2278A  V.36/RS-449 to DB25) are also available. A separate High Speed

V-Series module with V.35, RS-449 and X.21 interfaces are available to supports

speeds up to 8.192 Mb/s. Other WAN interfaces, including ISDN basic rate

interfaces (BRI) S/T/U and primary rate interfaces (PRI), E3/DS3, E1/T1, OC-3/

STM-1, STM-1e/EC-3, HSSI, DDS 4-wire, are available as slide-in modules or as

undercradles.

 Monitoring of LAN data over WAN and ATM is a standard feature. Real-time

monitoring of network conditions is a powerful testing capability to dig deeply

into the data if necessary.  The Agilent Advisor is a multitasking instrument; therefore users can perform

any of the active stimulus/response tests while the analyzer simultaneously

monitors their effect on the network.  Another powerful tool of the Advisor is traffic generation; it allows the

transmission of virtually any type of message or frame onto the network. To provide statistical information about the data on the network, the Agilent

Advisor analyzes every frame and count user definable events. A number of

counters have been pre-defined.  The Advisor is equipped with standard Bit Error Ratio Testing (BERT) and is

capable of generating BERT patterns onto V-series, T1, E1, E3, or DS3 WAN

links.

It does not matter if testing needs are for Frame Relay at E3/DS3 or HSSI

speeds or for low speed links, such as Async and Bisync, the Advisor provides

all of this functionality under one single handle solution.

Packet over SONET/SDH

As well as being a core network technology, Packet over SONET/SDH (PoS), also sometimes known as HDLC over SONET/SDH, is becoming an access technology at 155 Mb/s, used as an alternative to ATM.

The Agilent Advisor supports analysis of the two main variants of PoS:

· IETF PPP in HDLC-like frames over SONET/SDH (both the current and obsolete versions with version auto-detect and manual over-ride)

· Cisco HDLC over SONET/SDH

These are supported in the standard Agilent Advisor PPP and HDLC applications which also support other interfaces. Full rate capture of frames down to 7 bytes in length is provided, and full higher-layer decodes are available, including those for 3G and Mobile-IP. These and other decodes are also available over ATM and Ethernet, providing the Advisor with the most extensive 3G analysis capability under one handle

Frame Relay

No matter how complex the testing needs are, the Agilent Advisor with interfaces such as the T1, E1, E3/T3, or the HSSI lets the user test and troubleshoot complex WAN environments to solve WAN access and internetworking problems quickly.

The Agilent Advisor provides extensive real-time and post-processing test capabilities for the Frame Relay protocol according to the following recommendations:

 ITU-T Q.933 Annex A  ANSI T1.617 Annex D  Original Frame Relay consortium

The Advisor with its extensive Frame Relay testing capabilities allows the user to test:

 Physical Interface  Physical Layer  Link Layer  LMI Signaling  LMI/PING Responses  DLCI Assignments  CIR  Data Transfer  Protocol Distribution SLA

These basic verification techniques are general approaches to WAN analysis and troubleshooting that are accepted in the industry because of their systematic appeal and proven effectiveness.

Committed Information Rate (CIR) Measurement

CIR is one of the most important features for Frame Relay Management. CIR is a contract between the Service Provider and a User. This contract allows both parties to exchange information under controlled traffic conditions. CIR is the rate expressed in bits per second (bit/s) where the network agrees to transfer information under normal conditions. This rate is measured over the measurement interval Tc. The default value of Tc is 1 second. Figure 8 depicts a typical CIR measurement.

Figure 8: CIR Measurement.

Frame Relay (continued)

 The Agilent Advisor performs CIR monitoring for Frame Relay activity in real

time. The analyzer provides useful customer information such as:

 Statistical traffic activity per DLCI in graphical and tabular form

comparison of real traffic activity per DLCI against a fixed CIR value CIR

 Statistics in bits, frames and percentage per DLCI for:

-Non discardable traffic DE=0

-Below the Bc (Committed Burst).

-Discard Eligible traffic DE=1

-EIR (Excess Information Rate) Statistics in bits per second, frames per second, and percentage per DLCI for:

-Traffic below Bc (CIR)

-Traffic above the Bc, but below the sum of Bc+Be.

-Traffic above the sum of Bc+Be.

 Ability to modify the Bc and Be parameters in post processing mode to play

different CIR scenarios.

Store statistics for further analysis in the Agilent Reporter.

Service Level Agreement (SLA) Measurement

Another aspect of the Frame Relay service that often needs to be tested is provisioning as defined by the CIR (Committed Information Rate). Figure 9 depicts a typical SLA measurement.

Note: This measurement is sometimes called Service Level Agreement (SLA) testing or Service Level Definitions (see the Frame Relay Forum FRF.13 implementation agreement).

Figure 9: SLA Measurement.

Frame Relay (continued)

The Advisor transmits controlled packets into the network according to an established traffic contract between the user and the network, defined by the Frame Relay Forum FRF.13. This application characterizes the reliability of the Frame Relay Network by simulating user traffic and optional background traffic.

DLCI Statistics

The Agilent Advisor captures all the Frame Relay frames on the link and

performs an automatic study of all the possible DLCIs (1024). This application

tracks the most relevant information of each of the virtual channels in the

network. A complete network condition analysis is performed on all the PVCs

present on the link.

The DLCI Measurement displays both the CPE and the Network statistics:

Frame Relay (continued)

Real-time Capturing, Filtering and Searching

The Agilent Advisor now offers real-time IP and WAN filtering at rates up to 155Mb/s (up to DS3 for Frame Relay). This allows the user to isolate and analyze LAN and Frame Relay traffic on an ATM circuit or LAN traffic taking place on a Frame Relay circuit.

The real time filtering function provides application-level, LAN-centric troubleshooting on ATM or Frame Relay networks, thus allowing users to observe specific traffic types that may be causing trouble on the network. The user can filter by IP source and/or destination address for IP traffic encapsulated in Frame Relay, and additionally encapsulated in ATM. This feature maximizes valuable buffer space for optimal data collection of targeted LAN traffic, since the filtering takes place before data capture.

In addition to capture filtering performed in the hardware, the Agilent Advisor is able to gather counts of events such as cells or frames that meet the filtering criteria. More details of these features are given in technology specific sections in this specification.

Powerful filtering and search functionality allows the user to drill down further for troubleshooting purposes when post-processing data from a capture buffer or file. The same graphical user interface is used for pre and post filtering.

Capture Filters and Counters

Hardware counters and filters allow the user select frames to bring into the capture buffer. A typical Filters and Counters screen is depicted in figure 18. The Agilent Advisor will capture every frame, no matter what the traffic level, and that is exactly what is needed.

Up to 16 hardware data filters can be enabled simultaneously or individually turned on or off. A flexible and user-friendly menu helps the user define specific filters, counters, and triggers:

 Up to 16 hardware data filters (both sides of the network)  Enabled simultaneously or individually  Flexible, user-friendly menu for protocol specific filter and counter setup  Several user selectable actions for triggers  Filter up to 64 bytes into the frame

Display Filters and Searching

Display filtering and searching lets the user search through collected data to find specific IP addresses, values for protocol fields, or conversations on specific bi-directional virtual connections (by DLCI). The display filters provide the flexibility to select protocol attributes or specific protocols from a checklist, and the power to filter on any bit, byte or characteristic, such as protocol. For example, anyone can filter on Annex D without having to know any of the protocol specifics.

Post-processing allows the user quickly zoom in on selected criteria, from the traffic passing between specific devices to individual conversations. With post-processing, the user can do the following:

 Search through the data by record or by time stamp  Search for events or strings  Filter on protocols  Verify event-to-event timing  Search and view protocol errors  Print a range of cells or the entire buffer to printer or ASCII file  Export data in CSV (comma separated variables) format  Analyze statistics based on the buffered data

Simulation

Because the Agilent Advisor is a multitasking instrument, the user can perform any of the active stimulus/response tests while the analyzer simultaneously monitors the tests effect on the network.

The Agilent Advisor WAN provides a series of pre-written and pre-configured test routines; the user can easily write others. Test scripts can be customized and saved as a new test to build a library of powerful test sequences tailored to the users individual applications.

LMI Emulation

Emulation is understood in the Frame Relay Industry as the testing capability of a test device to replace either side of the network and provide the functions of the replaced side. This implies the implementation of appropriate state machines, which allow the tester to interact according to protocol standards.

The Agilent Advisor provides the following emulation capabilities according to the Frame Relay Forum Implementation Agreements FRF.1.1 and FRF.2.1 and ITU-T Q.933 Annex A.

 UNI-User (CPE) Emulation  UNI-Network (Switch) Emulation  NNI Emulation (bi-directional polling)

The UNI-User (CPE) emulation implies unidirectional polling from the User or Customer Premise Equipment (CPE) to the Network (Switch).

The UNI-Network (Switch) emulation implies unidirectional replies from the Network (Switch) to polling from the User or Customer Premises Equipment (CPE).

The NNI emulation implies bi-directional polling from Network to Network. (NNI).

The simulation application allows transmitting ICMP PING Requests to the network as well as the ability for sending a capture buffer to the network.

Li ne Status

The operation of the physical interface is often critical in determining the cause of network problems. Therefore, the Agilent Advisor tracks errors at the physical layer, and stamps the information with a 1 ms time stamp. Counts of error and alarm events are recorded on the display for both the line (network) and equipment (user) side. The time of the last occurrence of a particular event is recorded as well. Events are saved in the buffer and can be logged to disk. Figure 22 depicts a typical Line Status view.

On many occasions problems on the network can often be attributed to the transmission medium. Although the physical medium may be good for normal data transmission, it may not be able to handle high-speed WAN data. That is why the Advisor WAN has a powerful, built-in BERT (bit error ratio tester).

Table 2 Interface Application Support

ATM and WAN Interface Specifications

Unless otherwise stated, ATM and WAN interfaces provide two input ports and two output ports allowing any one of the following connection configurations to be used:

 Terminal Mode - uses one input and one output  Bridged Monitor Mode - uses both inputs and outputs for bi-directional

monitoring at test access points; a high input impedance should normally be selected

 Monitor Jack Mode  uses both inputs only for bi-directional monitoring at

protected monitor points

 Through Monitor Mode - uses both inputs and outputs providing bi-directional

repeater functionality plus bi-directional monitoring functionality. Each receiver input is terminated. The insert mode can place test traffic like SLA, PING, LMI emulation, Traffic Generation and Simulation.

The operation of the physical interface is often critical in determining the cause of network problems. Therefore, the Advisor tracks errors at the physical layer, and it stamps the information with a 1 ms time stamp. Signal events are recorded on the display for both the line (network) side as well as the equipment (user/subscriber) side. The time of the last occurrence of a particular event is recorded as well. Events are saved in the buffer and can be logged to disk.

Line status is displayed in real time. All of the events listed in the Physical layer alarms and statistics section for each interface below are saved in the buffer and counted in the line status display. These events may be logged to disk. Critical parameters marked with an asterisk (*) are also displayed in large green or red boxes in the line status display for easy at-a-glance viewing.
