Cisco Service Control Overview
This chapter provides a general overview of the Cisco Service Control solution. It introduces the Cisco
service control concept and capabilities.
It also briefly describes the hardware capabilities of the service control engine (SCE) platform and the
Cisco specific applications that together compose the complete Cisco service control solution.
• Cisco Service Control Solution, page 1-1
• Cisco Service Control Capabilities, page 1-2
• SCE Platform Description, page 1-3
• Management and Collection, page 1-5
Cisco Service Control Solution
The Cisco service control solution is delivered through a combination of hardware and specific software
solutions that address various operational and business-related challenges. Service providers can use the
SCE platform to support classification, analysis, and control of Internet and IP traffic.
CHA PTER
1
Service control enables service providers to:
• Capitalize on existing infrastructure.
• Analyze, charge for, and control IP network traffic at multigigabit wire line speeds.
• Identify and target high-margin content-based services and enable their delivery.
As access and bandwidth have become commodities where prices continually fall and profits disappear,
service providers have realized that they must offer value-added services to derive more revenue from
the traffic and services running on their networks.
Cisco service control solutions allow the service provider to capture profits from IP services through
detailed monitoring, precise, real-time control, and awareness of applications as they are delivered.
Service Control for Broadband Service Providers
Service providers of any access technology (DSL, cable, mobile, and so on) targeting residential and
business consumers must find new ways to get maximum leverage from their existing infrastructure,
while differentiating their offerings with enhanced IP services.
The Cisco service control application for broadband adds a layer of service intelligence and control to
existing networks that can:
Cisco SCE8000 Installation and Configuration Guide, Rel 3.1.7
OL-16478-02

Cisco Service Control Capabilities
• Report and analyze network traffic at subscriber and aggregate level for capacity planning
• Provide customer-intuitive tiered application services and guarantee application service level
agreements (SLAs)
• Implement different service levels for different types of customers, content, or applications
• Identify network abusers who are violating the acceptable use policy (AUP)
• Identify and manage peer-to-peer traffic, NNTP (news) traffic, and spam abusers
• Enforce the AUP
• Integrate Service Control solutions easily with existing network elements and business support
systems (BSS) and operational support systems (OSS)
Cisco Service Control Capabilities
The core of the Cisco service control solution is the network hardware device: the Service control engine
(SCE). The core capabilities of the SCE platform, which support a wide range of applications for
delivering service control solutions, include:
Chapter 1 Cisco Service Control Overview
• Subscriber and application awareness—Application-level drilling into IP traffic for real-time
understanding and controlling of usage and content at the granularity of a specific subscriber.
–
Subscriber awareness—The ability to map between IP flows and a specific subscriber to
maintain the state of each subscriber transmitting traffic through the SCE platform and to
enforce the appropriate policy on this subscriber’s traffic.
Subscriber awareness is achieved either through dedicated integrations with subscriber
management repositories, such as a DHCP or a RADIUS server, or through sniffing of RADIUS
or DHCP traffic.
–
Application awareness—The ability to understand and analyze traffic up to the application
protocol layer (Layer 7).
For application protocols implemented using bundled flows (such as FTP, which is
implemented using Control and Data flows), the SCE platform understands the bundling
connection between the flows and treats them accordingly.
• Application-layer, stateful, real-time traffic control—The ability to perform advanced control
functions, including granular bandwidth (BW) metering and shaping, quota management, and
redirection, using application-layer, stateful, real-time traffic transaction processing. This requires
highly adaptive protocol and application-level intelligence.
• Programmability—The ability to quickly add new protocols and adapt to new services and
applications in the service provider environment. Programmability is achieved using the Cisco
Service Modeling Language (SML).
Programmability allows new services to be deployed quickly and provides an easy upgrade path for
network, application, or service growth.
• Robust and flexible back-office integration—The ability to integrate with existing third-party
systems at the service provider, including provisioning systems, subscriber repositories, billing
systems, and OSS systems. The SCE provides a set of open and well-documented APIs that allows
a quick integration process.
1-2
• Scalable high-performance service engines—The ability to perform all of these operations at wire
speed.

Chapter 1 Cisco Service Control Overview
SCE Platform Description
The SCE family of programmable network devices performs application-layer stateful-flow inspection
of IP traffic, and controls the traffic based on configurable rules. The SCE platform is a network device
that uses ASIC components and reduced instruction set computer (RISC) processors to exceed beyond
packet counting and expand into the contents of network traffic. Providing programmable, stateful
inspection of bidirectional traffic flows, and mapping these flows with user ownership, SCE platforms
provide real-time classification of network use. The classification provides the basis of the SCE platform
advanced traffic-control and bandwidth-policing functionality. Where most bandwidth control
functionality ends, the SCE platform provides further control and shaping options, including:
• Layer 7 stateful wire-speed packet inspection and classification
• Robust support for more than 600 protocols and applications, including:
–
General—HTTP, HTTPS, FTP, Telnet, Network News Transfer Protocol (NNTP), Simple Mail
Transfer Protocol (SMTP), Post Office Protocol 3 (POP3), Internet Message Access Protocol
(IMAP), Wireless Application Protocol (WAP), and others
–
Peer-to-Peer (P2P) file sharing—FastTrack-KazaA, Gnutella, BitTorrent, Winny, Hotline,
eDonkey, DirectConnect, Piolet, and others
–
P2P VoIP—Skype, Skinny, DingoTel, and others
SCE Platform Description
–
Streaming and Multimedia—Real Time Streaming Protocol (RTSP), Session Initiation Protocol
(SIP), HTTP streaming, Real Time Protocol (RTP) and Real Time Control Protocol (RTCP),
and others
• Programmable system core for flexible reporting and bandwidth control
• Transparent network and BSS and OSS integration into existing networks
• Subscriber awareness that relates traffic and usage to specific customers
Figure 1-1 illustrates a common deployment of an SCE platform in a network.

Management and Collection
Subscriber Management
Where the Cisco service control application for broadband (SCA BB) enforces policies on different
subscribers and tracks usage on an individual subscriber basis, the Cisco service control management
suite (SCMS) subscriber manager (SM) may be used as middleware software for bridging between OSS
and SCE platforms. Subscriber information is stored in the SM database and can be distributed between
multiple platforms according to actual subscriber placement.
The SM provides subscriber awareness by mapping network IDs to subscriber IDs. It can obtain
subscriber information using dedicated integration modules that integrate with AAA devices, such as
RADIUS or DHCP servers.
Subscriber information may be obtained in one of two ways:
• Push Mode—The SM pushes subscriber information to the SCE platform automatically upon logon
of a subscriber.
• Pull Mode—The SM sends subscriber information to the SCE platform in response to a query from
the SCE platform.
Chapter 1 Cisco Service Control Overview
Service Configuration Management
Service configuration management is the ability to configure the general service definitions of a service
control application. A service configuration file containing settings for traffic classification, accounting
and reporting, and control is created and applied to an SCE platform. The SCA BB application provides
tools to automate the distribution of these configuration files to SCE platforms. This standards-based
approach makes it easy to manage multiple devices in a large network.
Service Control provides a GUI to edit and create these files and a complete set of APIs to automate their
creation.
Data Collection
Data collection occurs as follows:
1. All analysis and data processing functions of the SCE platform result in the generation of Raw Data
Records (RDRs), which the SCE platform forwards using a simple TCP-based protocol
(RDR-Protocol).
2. RDRs are processed by the Cisco service control management suite collection manager.
3. The collection manager software is an implementation of a collection system that receives RDRs
from one or more SCE platforms. It collects these records and processes them in one of its adapters.
Each adapter performs a specific action on the RDR.
RDRs contain a variety of information and statistics, depending on the configuration of the system.
Three main categories of RDRs include:
1-6
• Transaction RDRs—Records generated for each transaction, where a transaction is a single event
detected in network traffic. The identification of a transaction depends on the particular application
and protocol.
• Subscriber Usage RDRs—Records generated per subscriber, describing the traffic generated by that
subscriber for a defined interval.
• Link RDRs—Records generated per link, describing the traffic carried on the link for a defined
interval.

Introduction to SIPs and SPAs
SIPs and SPAs are a new carrier card and port adapter architecture used to increase modularity,
flexibility, and density across Cisco Systems routers for network connectivity. This section describes the
SIPs and SPAs and provides some guidelines for their use.
• SPA Interface Processors, page 2-4
• Specifying the SIP Subslot Location for a SPA, page 2-5
• Shared Port Adapters, page 2-5
• Modular Optics, page 2-6
• XFP Connections, page 2-6
SPA Interface Processors
The SIP module supported by the Cisco SCE8000 chassis is the SCE8000-SIP.
The following list describes some of the general characteristics of a SIP:
2-4
• A SIP is a carrier card that inserts into a slot in the chassis like a line card. It provides no network
connectivity on its own.
• A SIP contains one or more subslots (bays), which are used to house one or more SPAs. The SPA
provides interface ports for network connectivity.
• During normal operation the SIP should reside in the router fully populated either with functional
SPAs in all subslots, or with a blank filler plate (SPA-BLANK=) inserted in all empty subslots.

Cisco SCE8000-SIP subslots begin their numbering with “0” and have a horizontal orientation.
Figure 2-3 shows the subslot numbering for the Cisco SCE8000-SIP.
The Cisco SCE8000-SIP supports four subslots for the installation of SPAs, as follows:
• SIP subslot 0—Top–left subslot
• SIP subslot 1—Top–right subslot
• SIP subslot 2—Bottom–left subslot
• SIP subslot 3—Bottom–right subslot

Introduction to SIPs and SPAs
Shared Port Adapters
The SPA supported by the Cisco SCE8000-SIP is the 1-Port 10-Gigabit Ethernet SPA,
SPA-1X10GE-L-V2
The following list describes some of the general characteristics of a SPA:
• A SPA is a modular type of port adapter that inserts into a subslot of a compatible SIP carrier card
to provide network connectivity and increased interface port density. The Cisco SCE8000-SIP can
hold up to four SPAs.
Since the interfaces are connected in subscriber/network pairs, either two or four SPAs must be
installed.
• The supported SPA is a single-height SPAs, which inserts into one SIP subslot. (See Figure 2-4.)
Figure 2-4 Single-Height SPA Size
• Each SPA provides a one 10GBE port, which is the interface to either subscriber or network traffic.
These interfaces can be individually configured using the Cisco command-line interface (CLI).
• Either a blank filler plate or a functional SPA should reside in every subslot of an SIP during normal
operation to maintain cooling integrity. Blank filler plates are available in single-height form only.
Since the interfaces are connected in subscriber/network pairs, the SCE8000-SIP must be either
fully populated or have both the bottom bays covered with blank filler plates.

Modular Optics
The SPAs implement 10GBE small form-factor pluggable (XFP) optical transceivers to provide network
connectivity. An XFP module is a transceiver device that mounts into the front panel to provide network
connectivity.
Note It is highly recommended only to use the XFP modules listed as supported in this document. Use of
unsupported or unqualified XFP modules may affect reliability or operation.
Figure 2-5 10GBE Small Form-factor Pluggable (XFP)
Chapter 2 Introduction to the Cisco SCE8000 Platform
The interface connector on the 1-Port 10-Gigabit Ethernet SPA is a fiber optic receiver that supports one
XFP.
The types of optics modules that have been qualified for use with the 1-Port 10-Gigabit Ethernet SPA on
the Cisco SCE8000 platform are as follows:
• XFP-10GLR-OC192SR
• XFP-10GER-OC192IR
• XFP-10GZR-OC192LR
• XFP-10G-MM-SR
XFP Connections
The qualified XFPs include an optical transmitter and receiver pair integrated with Clock and Data
Recovery (CDR) integrated circuits. The XFPs provide high-speed serial links at 10.3125 Gbps on single
mode fibers.
The transmit side recovers and retimes the 10 Gbps serial data and passes it to a laser driver. The laser
driver biases and modulates a laser, enabling data transmission over fiber through an LC connector. The
receive side recovers and retimes the 10 Gbps optical data stream from a photo detector trans impedance
amplifier and passes it to an output driver.
See the label on the XFP for technology type and model.
XFP dimensions are:
• Height 12.5 mm
2-6
• Width 18.35 mm
• Length 71.1mm

The Cisco SCE8000 platform optical bypass module preserves the service provider 10GBE links under
all circumstances. At power failure the bypass is automatically activated. It can also be activated by the
Cisco SCE8000 software.
The Cisco SCE8000 platform already includes an internal electrical bypass, but it is strongly
recommended to use the optical bypass module for addressing the following scenarios:
• During platform reboot (SW reload)—If the external bypass module is not used, there is a 5-second
period (at most) during which the link is forced down (cutoff functionality).

• During a power failure —The Cisco SCE8000 has two power supplies. A power failure occurs only
when both of them fail.
In a case where the Cisco SCE8000 platform must be replaced, it is possible to remove the bypass
modules from the SCE8000 chassis without disconnecting them from the network and then reinstall them
in the new SCE platform, so that traffic links are preserved even in a case of complete failure and
replacement of the Cisco SCE8000 platform. (See Replacing the Optical Bypass Module without
Disrupting Traffic on the Link, page 9-26.)
Optical Bypass Functionality
The optical bypass module is connected bump-in-the-wire in the 10-GBE link. It is then connected to the
Cisco SCE8000 platform with two types of connections:
• 10GBE optical connections for data link traffic — 10 GBE connections from the optical bypass
module to one pair of the 10GBE SPA ports.
• Control connection — Connection to the RJ-11 External Bypass connector on the SCE8000-SCM,
so the optical bypass is activated if the Cisco SCE8000 platform fails.
The Cisco SCE8000 Optical Bypass
Optical Bypass Module Connectivity
The optical bypass module functions as follows:
• Under normal conditions, the bypass module directs traffic to flow via the Cisco SCE8000.
• Under failure conditions, the optical bypass shortcuts the interfaces that are connected to the traffic
link, and all traffic flows through the optical bypass module, bypassing the SCE platform.
Figure 2-7 Optical Bypass Module Connectivity
Optical Bypass Module (OPB-SCE8K)
There are two types of optical bypass modules to support different optic types:

• OPB-SCE8K-SM supports Single-Mode optics and should be used with SCE8000 equipped with
Single-Mode optics.

Up to two optical bypass modules can be mounted internally, supporting inline insertion into two links.
Up to four optical bypass modules can be mounted using an external mount panel
(OPB-SCE8K-EXT-PNL). A single panel can serve two SCE8000 platforms, each cutting two links or
up to four SCE8000 platforms, each cutting a single link.

Fan Assembly
The Cisco SCE8000 Optical Bypass
The system fan assembly, located in the chassis, provides cooling air for the installed modules. Sensors
on the fan assembly and within the system monitor the internal air temperatures. If the air temperature
exceeds a preset threshold, the environmental monitor displays warning messages.
Figure 2-9 Fan Assembly
If an individual fan within the assembly fails, the FAN STATUS LED turns red. To replace a fan
assembly, see Removing and Replacing the Fan Assembly, page 9-10.

Power Supplies
The Cisco SCE8000 platform supports redundant AC- or DC-input power supplies. The following power
supplies are available for the Cisco SCE8000 platform:
• 2700 W DC input (PWR-2700-DC/4): uses an external terminal block on the back side of the chassis
• 2700 W AC input (PWR-2700-AC/4): uses an external power cord directly connected to the AC
