CHAPTER 1
Overview
This chapter provides a general overview of the Cisco Service Control solution. It introduces the
Cisco Service Control concept and the Service Control capabilities. It also briefly describes the
hardware capabilities of the Service Control Engine (SCE) platform, as well as the Cisco specific
applications that together compose the total Cisco Service Control solution.
This chapter contains the following sections:
• The Cisco Service Control Concept 1-1
• Cisco Service Control Capabilities 1-2
• The SCE Platform 1-3
• Management and Collection 1-4
• Service Configuration Management 1-5
The Cisco Service Control Concept
The Cisco Service Control solution is delivered through a combination of purpose-built hardware
and specific software solutions that address various Service Control challenges faced by service
providers. The SCE platform is designed to support classification, analysis, and control of
Internet/IP traffic.
Service Control enables service providers to create profitable new revenue streams while
capitalizing on their existing infrastructure. With the power of Service Control, service providers
have the ability to analyze, charge for, and control IP network traffic at multi-Gigabit wire line
speeds. The Cisco Service Control solution also gives service providers the tools they need to
identify and target high-margin content-based services, and enable their delivery.
As the downturn in the telecommunications industry has shown, IP service providers' business
models need to be reworked to make them profitable. Having spent billions of dollars to build
ever larger data links, providers have incurred massive debts and rising costs. At the same time,
access and bandwidth have become a commodity 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. However, capturing real
profits from IP services requires more than simply running those services over data links; it
requires detailed monitoring and precise, real-time control and awareness of services as they are
delivered. Cisco provides Service Control solutions that allow the service provider to bridge this
gap.
Cisco SCE 2000 4xGBE Installation and Configuration Guide
OL-7824-04 1-1
Cisco Service Control Capabilities
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 new layer of service intelligence and
control to existing networks that can:
• Report and analyze network traffic at subscriber and aggregate level for capacity planning
• Provide customer-intuitive tiered application services and guarantee application SLAs
• Implement different service levels for different types of customers, content, or applications
• Identify network abusers who are violating the Acceptable Use Policy
• Identify and manage peer-to-peer, NNTP (news) traffic, and spam abusers
• Enforce the Acceptable Use Policy (AUP)
• Integrate Service Control solutions easily with existing network elements and BSS/ OSS
systems
Chapter 1 Overview
Cisco Service Control Capabilities
At the core of the Cisco Service Control solution stands the purpose-built 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:
• 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 for
maintaining the state of each subscriber transmitting traffic through the SCE platform, and
enforcing the appropriate policy on this subscriber's traffic
Subscriber awareness is achieved using dedicated integrations with subscriber
management repositories, such as a DHCP or a Radius server, or via 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 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 easily adapt to new
services and applications in the ever-changing service provider environment.
Programmability is achieved using the Cisco Service Modeling Language (SML).
Cisco SCE 2000 4xGBE Installation and Configuration Guide
1-2 OL-7824-04
Chapter 1 Overview
Programmability is required for new services to be deployed quickly, and it 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 welldocumented APIs that allows a quick and robust integration process.
• Scalable high-performance service engines—The ability to perform all these operations at
wire speed.
The SCE Platform
The SCE family of programmable network devices is capable of performing application-layer
stateful-flow inspection of IP traffic, and controlling that traffic based on configurable rules. The
SCE platform is a purpose-built network device that uses ASIC components and RISC processors
to go beyond packet counting and delve deeper into the contents of network traffic. Providing
programmable, stateful inspection of bidirectional traffic flows and mapping these flows with user
ownership, the SCE platforms provide a real-time classification of network usage. This
information provides the basis of the SCE platform advanced traffic-control and bandwidthshaping functionality. Where most bandwidth shaper functionality ends, the SCE platform
provides more control and shaping options including:
The SCE Platform
• Layer 7 stateful wire-speed packet inspection and classification
• Robust support for over 600 protocols and applications including:
• General—HTTP, HTTPS, FTP, TELNET, NNTP, SMTP, POP3, IMAP, WAP, and others
• P2P file sharing—FastTrack-KazaA, Gnutella, BitTorrent, Winny, Hotline, eDonkey,
DirectConnect, Piolet, and others
• P2P VoIP—Skype, Skinny, DingoTel, and others
• Streaming & Multimedia—RTSP, SIP, HTTP streaming, RTP/RTCP, and others
• Programmable system core for flexible reporting and bandwidth control
• Transparent network and BSS/OSS integration into existing networks
• Subscriber awareness that relates traffic and usage to specific customers

Management and Collection
The following diagram illustrates a common deployment of an SCE platform in a network.
Figure 1-1: SCE Platform in the Network
Chapter 1 Overview
Management and Collection
The Cisco Service Control solution includes a complete management infrastructure that provides
the following management components to manage all aspects of the solution:
• Network management
• Subscriber management
• Service Control management
These management interfaces are designed to comply with common management standards and to
easily integrate with existing OSS infrastructure.
Figure 1-2: Service Control Management Infrastructure
Cisco SCE 2000 4xGBE Installation and Configuration Guide
1-4 OL-7824-04
Chapter 1 Overview
Network Management
Cisco provides complete network FCAPS (Fault, Configuration, Accounting, Performance,
Security) Management.
Two interfaces are provided for network management:
• Command-Line Interface (CLI)—The CLI is accessible through the Console port or
through a Telnet connection; it is used for configuration and security functions
• SNMP—SNMP provides fault management via SNMP traps, as well as performance
monitoring functionality
Subscriber Management
In cases where SCE 2000 is used to enforce different 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 the OSS and
the SCE platforms. Subscriber information is stored in the SM database and can then be
distributed between multiple platforms according to actual subscriber placement.
Service Configuration Management
The SM provides subscriber awareness, mapping network IDs to subscriber IDs. It obtains
subscriber information using dedicated integration modules, which 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—On-demand, in response to a query from the SCE platform to the SM
Collection
The Cisco Service Control solution generates usage data and statistics from the SCE platform and
forwards them as Raw Data Records (RDRs), using a simple TCP-based protocol (RDRProtocol). The Service Control solution provides the Cisco Service Control Management Suite
(SCMS) Collection Manager (CM) software as an implementation of a collection system,
listening in on RDRs from one or more SCE platforms, and processing them on the local machine.
The data is then stored for analysis and reporting functions, as well as simple collection and
presentation of data to additional OSS systems such as billing.
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 & reporting, and control is created and applied to an SCE platform.
SCA BB provides tools to automate the distribution of these configuration files to SCE platforms,
and this simple, standards-based approach makes it easy to manage multiple devices in a large
network.
Service Control provides an easy-to-use GUI to edit and create these files, as well as a complete
set of APIs to automate their creation.

CHAPTER 3
T opology
This chapter describes the possible deployment topologies of the SCE 2000. The Cisco SCE
solution offers a number of basic topology options that permit the user to tailor the SCE Platform
to fit the needs of a particular installation. An understanding of the various issues and options is
crucial to designing, deploying, and configuring the topology that best meets the requirements of
the individual system.
This chapter contains the following sections:
• The SCE 2000 Platform 3-1
• Topology Considerations 3-1
• Physical T opologies 3-4
The SCE 2000 Platform
The SCE 2000 introduces a solution for dual links with load sharing and asymmetrical routing
and support for fail-over between two SCE platforms.
The SCE 2000 supports wire speed processing of full-duplex 2-Gigabit Ethernet streams. The
SCE 2000 can, therefore, be deployed in a multi-link environment, either in a single or dual SCE
platform topology.
• single SCE 2000 topology — Provides increased network capacity and the ability to
process both directions of a bi-directional flow, processing both the upstream and
downstream paths of a flow, even if they traverse different links
• dual SCE 2000 topology (cascade) — cascaded SCE 2000s provide high-availability and
fail-over solution and maintain the line and service in case of SCE 2000 failure.
T opology Considerations
There are several issues that must be considered in order to arrive at the optimum configuration of
the topology-related parameters:
• Functionality — Will the system be used solely to monitor traffic flow, with report
functionality only, or will it be used for traffic flow control, with enforcement as well as
report functionality?
Cisco SCE 2000 4xGBE Installation and Configuration Guide
OL-7824-04 3-1
Topology Considerations
• Number of links — The SCE 2000 may be connected to one or two GBE links. This is
relevant for both Inline and Receive-Only topologies.
• Redundancy — Must the system be designed to guarantee uninterrupted SCE 2000
functionality? If so, there must be a backup SCE 2000 Platform to assume operation in case
of failure of the primary device.
• Link continuity — How should the SCE 2000 respond to platform failure with regard to
link continuity? Should traffic flow continue even though the unit is not operating, or be
halted until the platform is repaired/replaced?
These issues determine three important aspects of system deployment and configuration:
• How many SCE 2000 Platforms are needed and how will they be installed?
• Physical topology of the system — The actual physical placement of the SCE 2000 in the
system.
• Topology-related configuration parameters — The correct values for each parameter must
be ascertained before configuring the system to make sure that the system will function in
the desired manner.
Chapter 3 Topology
Functionality
Number of links
Redundancy
The SCE 2000 can serve one of two general functions:
• Monitoring and Control — The SCE 2000 monitors and controls traffic flow. Decisions are
enforced by the SCE 2000 depending on the results of the monitoring functions of the SCE
2000 and the configuration of the Service Control Application for Broadband or Mobile
solution.
In order to perform control functions, the SCE 2000 must be physically installed as an inline
installation and the connection mode must be “inline”.
• Monitoring only — The SCE 2000 monitors traffic flow, but cannot control it.
Either an inline installation or an optical splitter installation may be used for monitoring only.
In the latter case connection mode must be “receive-only”.
The SCE 2000 can be deployed in a single GBE link or in two GBE links. The two-link topology
may implement load-sharing and the SCE 2000 in this case is able to process both directions of a
bi-directional flow even if they split to both links.
When a high degree of reliability is desired, a second SCE 2000 Platform should be installed to
provide backup operation capabilities. The combination of two SCE 2000s guarantees
uninterrupted functioning in case of a failure of one of the platforms. The two SCE 2000s are
cascaded, so that, although all processing is performed only in the active SCE 2000, the standby
SCE 2000 is constantly updated with all the necessary information so that it can instantly take
over processing the traffic on the data links should the active SCE 2000 fail.
If only preservation of the network links is required, and uninterrupted functionality of the SCE
2000 is not required, a single SCE 2000 is sufficient.
