1.1 About the 10G Probe

1.1.1 VB330 – Overview

The VB330 10G Probe was made speciﬁcally for IPTV backbone network monitoring. Equipped with two 10G SFP+ optical Ethernet inputs, the 10G Probe provides detailed IP packet monitoring of a very high

number of Ethernet streams, suitable for core networks carrying extreme amounts of media signals.

The OTT software option is available on the VB330 and enables monitoring of up to 500 adaptive bitrate

channels in steps of 5 or 50 (Bulk OTT option) OTT engines depending on licensing.

A built-in web server in the VB330 allows remote signal monitoring using a standard web browser. This

can be managed either through a separate Ethernet network, or by using the regular video/data network

– both IPv4 and IPv6 are supported.

The VB330 10G Probe can also be managed via the VideoBRIDGE Controller. The VideoBRIDGE

Controller will add management features like alarm aggregation and report functionality.

The VB330 10G Probe is a module housed in a 1 RU chassis. Several VB330 modules may be installed

in one chassis, extending the monitoring capacity.

Note: The VB330 does not support RF modules such as VB242, VB252, VB262, and VB272.

VB3xx 10G Probe User’s Manual version 5.3 9

1.1.2 10G Probe – Functionality

An IP-based network is fully transparent with respect to signal contents quality, provided that the IP

packets arrive, and provided that they arrive in time. The 10G Probe therefore uses the patented MediaWindow to allow monitoring at-a-glance of packet loss and errors in inter-packet arrival time. This

way the operator can conveniently ensure correct signal quality at IP-level.

The advanced Ethernet protocol analysis tool automatically detects all protocols carried over Ethernet

past the port the 10G Probe is connected to, and it displays statistics like percentage utilization of the interface and percentage of the different transported protocols. This gives the 10G Probe a real-time sniffer capability.

The 10G Probe allows the user to deﬁne a Return Data Path (RDP), using the regular video/data network

or the management network to return a stream. A faulty signal can then be further analyzed at the studio premises, when necessary.

The recording functionality allows the user to record a stream, either triggered manually by the user or

triggered by a user deﬁned alarm.

Full Service Monitoring (FSM) checks that vital system components like CA-servers are active.

Optional Ethernet TR 290 monitoring allows the operator to check parameters like transport stream sync and PSI/SI standards conformity. This option also performs further PSI/SI analysis, making it possible to

view PSI/SI contents. PID and service bitrates are also continuously measured.

Optional OTT monitoring allows the operator to set up active testing of Over-the-top type signals as found in adaptive bitrate streaming architectures. Formats supported include AppleTMHLS, Microsoft Smoothstream, RTMP, MPEG DASH, AdobeTMHDS and Nullsoft SHOUTcastTM.

10 VB3xx 10G Probe User’s Manual version 5.3

The 10G Probe can be expanded through licence options to monitor the T2MI protocol layer as found in

DVB-T2 networks.

The 10G Probe can also be licensed with an SCTE 35 option that allows monitoring and logging of splice

time codes embedded in the transport streams.

A simpliﬁed diagram of the alarm handling mechanisms of the 10G Probe is shown in ﬁgure 2.2. The

input signals are continuously analyzed, and measured data are checked against user deﬁned threshold

values. If the data do not comply with the threshold values alarms will be generated. The overall alarm

settings further make it possible to enable and disable alarms, thus deﬁning which alarms should be reported in the 10G Probe alarm list and sent as SNMP traps to an external management system.

3 SAFETY

Read the installation instructions before connecting the chassis unit to the power source. Do not install the chassis unit with power on.

The chassis is intended for installation in restricted access areas. A restricted access area can

be accessed only through the use of a special tool, lock and key, or other means of security.

Blank face plates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis, they provide electromagnetic interference shielding and they direct the ﬂow of cooling air through the chassis. Do not operate the chassis unit unless all modules, face plates, front covers and rear covers are in place.

Only trained and qualiﬁed personnel should be allowed to install, replace or service this equipment.

This equipment must be installed and maintained by service personnel as deﬁned by AS/NZS

3260. Incorrectly connecting this equipment to a general-purpose outlet could be hazardous.

The 10G Probe is shipped with an SX SFP+ module that is equipped with a Class 1 laser. Do not

stare into open optical ports. Note that if the SFP+ module is replaced special precautions may have to be taken – refer to the manufacturer’s instructions. SFP+ modules are static sensitive devices, and ESD-preventive measures should be taken when handling them, to avoid damage.

Ultimate disposal of this product should be handled according to all national laws and regulations.

To prevent the system from overheating, do not operate it in an area that exceeds the maximum

ambient temperature of 45 degrees Celsius.

Do not work on the system or connect or disconnect cables during periods of lightning activity.

The chassis requires short-circuit (overcurrent) protection. Ensure that the protective device is

rated not greater than 120 VAC, 15 A; 240 VAC, 16 A; 60 VDC, 20 A.

4.6 Installing the Unit in a Rack

The following equipment is needed for hardware installation of the unit:

• 4 rack screws

• A screw driver for the rack screws

• For rear mounting: a size 2 Phillips screwdriver for rack ear screws

4.6.1 Default Installation — Connectors at the Front of Rack

By default the Enhanced chassis is shipped with rack ears for front mounting of the unit. The rack ears are designed to support the weight of the unit, so no additional support, like a rack shelf, is needed.

When deciding where to locate the unit, make sure there is sufﬁcient space surrounding the unit to allow

efﬁcient cooling, refer to section 4.2.2.

Use four rack screws to install the unit in the rack.

4.6.2 Optional Installation — Connectors at the Rear of Rack

For rear mounting of the chassis, the rack ears should be moved prior to rack installation. Unscrew the six size 2 Phillips screws holding the rack ears, and move the six screws covering the rear mounting holes to the front mounting holes. Remount the rack ears at the rear end of the unit.

Install the unit as described in section 4.6.1.

4.6.3 Optional Installation — Mid-Mounting

The Enhanced Chassis allows rack ears to be mid-mounted. This can be convenient if the chassis is

installed in a telco environment. Unscrew the six size 2 Phillips screws holding the rack ears, and move

VB3xx 10G Probe User’s Manual version 5.3 19

the six screws covering the mid mounting holes to the front mounting holes. Remount the rack ears at the middle of the unit.

Figure 4.5: Rack Ears Mounting – Side View of Enhanced Chassis Showing Screw Holes

4.7 Powering up the Unit

Once the chassis is securely mounted and signal cables are connected, it can be powered up by connecting the power cable to a mains source. When the power cable is connected the power LEDs of the individual optional modules should light up and the chassis fans should operate.

Note that it will take some time from power-up until the modules can be accessed via the management interface – typically the start-up may take up to two minutes.

4.8 Initial Conﬁguration

There are two alternative ways of performing an initial conﬁguration of the probe module:

1. By using the preconﬁgured IP address of the probe management port

2. Via serial console emulated over USB

For most users the ﬁrst method will be the easiest.

Note that if there are two 10G Probe modules in the chassis, each module should be conﬁgured individually, one by one.

4.8.1 Initial Conﬁguration Using the Pre-Set IP-Address

The 10G Probe modules are shipped with the following factory settings:

Management (eth1) IP address: 10.0.20.101

Management (eth1) subnet mask: 255.255.0.0

In order to connect to the eth1 management port, the PC used for set-up should have corresponding

4.8.2 Initial Conﬁguration Via Serial Console Emulated Over USB

If the 10G Probe for some reason cannot be reached through Ethernet communication, the initial set-up may be performed via serial console emulated over USB. For the initial set-up, you must do the following:

1. Installing a driver for the USB communication, if not already supported by the operating system

2. Setting the management IP address

VB3xx 10G Probe User’s Manual version 5.3 21

Figure 4.7: Connecting to the serial console over USB

Most operating systems will have native support for the FT232 driver needed. When a USB cable is connected between a PC and the 10G Probe, the operating system will detect a new USB device. For

Windows, the new device will appear as a COM port in the

If your operating system does not detect the probe, you may have to download and install a driver for it. The driver may be downloaded directly from the chip manufacturer at Select ﬁrst Drivers, then VCP followed by the operating system (VCP is short for Virtual COM Port).

If it is not already connected, connect the USB cable between the USB port on the probe and a USB port on the PC.

The 10G Probe is equipped with two network interfaces called management (or eth1) and data/video

SFP+ B (or eth0). It is necessary to conﬁgure at least one of these interfaces from the terminal and then do the rest of the setup from a web browser. Depending on the installed license, an additional data interface, labelled data2 (eth2), may also be available.

The 10G Probe supports both in-band management (i.e. using eth0 for both data/video and management)

and separate management (i.e. using eth1 for management). In any case make sure that the subnets conﬁgured for eth0 and eth1 do not overlap – otherwise the probe will not work properly. Note that if IP addresses for eth0 and eth1 are conﬁgured so that the subnets overlap, the IP address of one of the ports will be automatically set to 1.1.1.1 by the 10G Probe.

If you have multiple OTT engines installed (1 to 50 are allowed) then select which engine to assign to the channel. Any number of OTT channels can be assigned to each OTT engine. Each engine works in parallel to each other.

Note:

When monitoring both multicast (UDP) and OTT (TCP) trafﬁc, we recommend using different network interfaces. Mixing the two trafﬁc types on the same network can have unwanted impact on the monitored signals. The interface used for OTT trafﬁc is controlled using the view.

5.4 Adjusting Alarm Thresholds

When the probe inputs and streams have been deﬁned using default thresholds, the result will usually

be a number of more or less permanent alarms, some which may not be relevant under the current circumstances. In order for the user to get rid of unwanted alarms, the probe provides alarm ﬁltering functionality in the form of alarm thresholds and alarm on/off selection.

Multicasts

By default Ethernet thresholds are set to raise alarms when service affecting errors occur, that are caused by the network. There may however be reasons for these thresholds to be altered, for instance to reﬂect receiver robustness in the case of IAT, or to reﬂect a TS into IP mapping different from the default

(7TS/UDP). Creating a new threshold template is done either by copying an existing one and altering the

copy, or by creating a new threshold template from scratch. The Ethernet thresholds are deﬁned in the

changed if there are tables that are not relevant for a system, or if the user requires alarm functionality that exceeds the ETR 290 guidelines. The ETR engines has a lot of powerful functionality not enabled by default, for instance the ability to raise alarms if the number of services present in a signal is lower than a preset limit.

The default PID and service thresholds do not affect alarming at all, they are completely transparent. The

thresholds may be altered for instance in order to mask an alarm generated by an unreferenced PID or to ensure an alarm is raised if a service or PID bitrate is outside preset limits.

Creating a new threshold template is done either by copying an existing one and altering the copy, or by creating a new threshold template from scratch. The thresholds are deﬁned in these views: ETR thresh., ETR 290 — PID thresh., ETR 290 — Service thresh.

Note that different web browsers behave differently with respect to memory leaking, and if the VB330 GUI should be available at all times the browser should be selected carefully. A browser memory leak manifests itself as the browser responding more and more slowly, and this is corrected by closing down the application and restarting.

The interface is easy and intuitive to use. Navigate by clicking on the tabs just below the 10G Probe logo.

Some of the pages have their own tabs for accessing nested pages. The bottom frame of the interface is always the Alarms & events list, usually referred to as the hidden by clicking the Toggle link, which is displayed as an arrow head.

Figure 6.1 shows an overview of the alarm handling in the 10G Probe. It is useful to obtain an understanding of the alarm processing of the 10G Probe – in particular how threshold settings and alarm setup

VB3xx 10G Probe User’s Manual version 5.3 39

SNMP traps to support third party management systems. Refer to Appendix: VB330 Versus VBC Alarms for a description of alarm handling in the VideoBRIDGE Controller.

The 10G Probe distinguishes between events and alarms. The ETR software module will always generate

alarms and the Systems software module will always generate events. The Ethernet software module will

by default generate events for errors that are resolved within 1 second, otherwise it will generate alarms. This can be overridden by checking the ‘Treat ethernet events as alarms’ box in the view. The OTT module generates alarms only.

keeps them in non-volatile memory so that they survive reboots and power-outages. This opens up a lot

of possibilities for probes that cannot be reached while doing measurements and for probes that need to

be powered down and consulted elsewhere. It also severely increases the size of the alarm list allowing

browsing of older alarms.

6.3 OTT (Option)

6.3.1 OTT — Active testing

The OTT option enables monitoring of up to 500 OTT channels. Up to 50 OTT engines (depends on

license) can operate in parallel, and each engine licensed allows any channels to be analyzed. Each

engine analyses channels in series and can be conﬁgured with any number of channels up to the

maximum allowed by the license.

The 10G Probe will parse a channel’s manifest ﬁle, and for a live channel one of the latest chunks in each

OTT proﬁle’s chunk sequence will be analyzed. The engine then moves on to the next OTT channel in

the channel list deﬁned by the user. For a VoD channel the OTT engine will analyze all chunks in the VoD

ﬁle, one in each round-robin loop.

If manifest ﬁle parsing or chunk analysis reveals an error, an alarm will be raised. Note that some alarms

depend on user deﬁned threshold values. Alarms must also be enabled in the view.

Thumbnail decoding is available for

some types of encrypted HLS channels.

The following OTT information is displayed in the Active testing view:

will increase CC errs by one. CC errors are serious as they will in practice usually

result in visual video artefacts (‘blocking’) if occurring on the video PIDs. CC errors can be due to an erroneous input signal to the streaming head-end (e.g. from satellite rain fading or changes in the uplink). Alternatively, CC errors can arise from IP packets being dropped in the network.

Average Inter-Arrival Time. The average time between consecutive IP frames (in

milliseconds). Recalculated each second.

The Minimum Inter-Arrival Time is the minimum registered time between two consecutive IP frames carrying video. Units are in milliseconds.

The Maximum Inter-Arrival Time is the maximum registered time between two consecutive IP frames carrying video. Units are in milliseconds. The Max-IAT is a measure of the maximum amount of network-induced packet jitter present. IP packet jitter affects video quality and should be minimized.

Accumulated number of dropped IP-frames due to network errors. Only available for

multicasts that carry RTP information. When running video inside an RTP wrapper it is possible to exactly deduce the number of dropped IP frames due to network issues. This is possible as a result of the 16-bit sequence counter inside the RTP header. The following sequence will generate an RTP drops of +3: . . ., 10, 11, 12, 16, 17, 18, . ..

Accumulated number of duplicate IP-frames. Only available for multicasts that

carry RTP information. Duplicate IP-frames in the network can occur under normal circumstances and does not necessarily indicate network problems. The following sequence will generate an RTP dups of +2: . . . , 10, 11, 12, 12, 12, 13, 14, . . .

Min hole size:

Accumulated number of times a packet has been found to be out of order. Only

available for multicasts that carry RTP information. An out-of-order situation is deﬁned to have occurred when the current sequence number is lower than the previous one. The following sequence will generate an RTP ooo of +2 (since there are two occurrences): . .. , 10, 11, 15, 12, 16, 17, 13, 14, 18, 19, . ..

The maximum number of packet positions an out-of-order packet has been moved relative to its correct position. So for example 1,2,3,5,6,7,8,4,9,10 will result in an RTP lag of 4. The RTP lag is a good measure of how big a packet re-ordering buffer is needed in the receiving equipment to re-order packets.

Minimum number of consecutive dropped RTP packets. The sequence 1,2,3,10,11,12,15 gives a min hole size of 2.

The probe will try to generate thumbnail pictures for all streams. For multi-program transport streams (MPTS) the ﬁrst video component is selected. MPEG-2, H.264/MPEG-4, H.265/HEVC and JPEG 2000 video formats in standard deﬁnition, high deﬁnition or ultra-high deﬁnition are supported in MPEG-2

transport streams, as well as SMPTE 2022-6 uncompressed video in RTP streams.

The thumbnail update rate will depend on how the streams are coded and if they are standard deﬁnition,

Shown while the thumbnail engine is trying to decode a thumbnail picture and more precise status information has not yet been obtained. This icon is typically displayed after probe reboot or if new streams have recently been joined.

Shown if the service does not carry a video PID — which is the case for radio services.

The stream contains no service, as signaled in PSI/SI.

The signal cannot be decoded due to excessive CC errors or RTP packet drops.

The probe does not support thumbnail generation for this protocol mapping.

This icon is shown if the probe is unable to receive or analyze the PMT PID. Only streams with PSI information can have thumbnails decoded since the probe does not support a

manual speciﬁcation of the video PID.

The

Media Window view provides an at-a-glance status for each of the multicasts/unicasts being monitored. From the graphs it is easy to see the jitter characteristics of the signal and if there is packet loss or CC errors present in the signal. Periods of no signal are also displayed.

The measurements are always aggregated over a time interval – typically one second. The IAT(max) is

the maximum time measured between two neighboring IP frames within the measurement time interval

(the peak packet Inter-arrival time). IAT is expressed in milliseconds.

The MLR is the peak estimated number of lost MPEG-2 Transport Stream packets inside any second within the actual time period. The number of lost TS packets is derived from the continuity counters inside

the TS packet headers.

A common scenario is to have 7 TS packets per UDP frame. Losing an IP packet will therefore usually (but not always) result in an MLR of 7 (not always the case because some TS packets such as null

packets or PCR packets do not carry a valid CC ﬁeld).

RTP loss %:

Percentage of time an average stream that matches the ﬁlter experiences RTP packet loss inside selected time period. Example: If the caught by ﬁlter:

Last 1m

period is selected and there are totally three streams

• stream A: present for 60 seconds, 4 RTP error seconds

• stream B: present for 30 seconds, 0 RTP error seconds

• stream C: present for 30 seconds, 5 RTP error seconds

RTP loss % = 9ES / 120s RTP loss % = 9ES / 3streams / 120s *100% = 7.5%

MLR %:

Avg str bitr: The average bitrate for streams matching the associated ﬁlter.

Percentage of time an average stream that matches the ﬁlter experiences MLR inside selected time period.

The calculation is similar to that for RTP loss %.

Avg str duration:

Clicking the icon next to each value brings up the detailed graph window.

The stream duration is calculated for each stream by identifying the stream’s

average stream alive counter inside the selected time period, then multiply by 2. The stream alive counter is the number of seconds the stream has existed. This gives accurate results for streams that begin within the selected time period,

but may give up to twice the real bitrate for streams that begin (long) before the

selected period.

Examples: a stream exists for 100 seconds, and begins within the selected period. The calculation becomes:

Stream duration = (1+2+. . . +100)/100*2 = 101

If the same stream started 50 seconds before the selected period, the calculation

becomes:

Stream duration = (51+52+. . . +100)/50*2 = 151
