CHAPTER 1
General 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 and 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
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 multigigabit 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 to 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 faced rising costs. At the same
time, 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. 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.

OL-7826-05 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 General Overview
Cisco Service Control Capabilities
The core of the Cisco Service Control solution is 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 in
order 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 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 4/8xFE Installation and Configuration Guide
1-2 OL-7826-05
Chapter 1 General Overview
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 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 real-time classification of network usage. This information
provides the basis of the SCE platform advanced traffic-control and bandwidth-shaping
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 and 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 General 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
integrate easily with existing OSS infrastructure.
Figure 1-2: Service Control Management Infrastructure
Cisco SCE 2000 4/8xFE Installation and Configuration Guide
1-4 OL-7826-05
Chapter 1 General 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)—Accessible through the Console port or through a Telnet
connection, the CLI is used for configuration and security functions.
• SNMP—Provides fault management (via SNMP traps) and performance monitoring
functionality.
Subscriber Management
Where the Cisco Service Control Application for Broadband (SCA BB) enforces 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 be distributed between multiple platforms according to actual subscriber
placement.
Management and Collection
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.
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 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 and a complete set of
APIs to automate their creation.
Cisco SCE 2000 4/8xFE Installation and Configuration Guide
OL-7826-05 1-5
Management and Collection
Data 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 Cisco Service Control Management Suite (SCMS) Collection Manager (CM)
software implements the collection system, listening in on RDRs from one or more SCE

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-Fast 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 4/8xFE Installation and Configuration Guide
OL-7826-05 3-1
Topology Considerations
• Number of links — The SCE 2000 may be connected to one or two FE 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 external switch 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 FE link or in two FE links. The two-link topology may
implement load-sharing and the SCE 2000 in this case is able to process both directions of a bidirectional 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.

Chapter 3 Topology
Link Continuity
Topology Considerations
The bypass mechanism of the SCE 2000 allows traffic to continue to flow, if desired, even if the
device itself is not functioning.
Note that when the SCE 2000 is connected to the network through an external switch, a failure of
the SCE 2000 does not affect the traffic flow, as the traffic continues to flow through the external
switch.
Bypass Mechanism
The SCE 2000 includes a Network Interface Card with a bypass mechanism that is enabled upon
SCE 2000 failure. In addition, when connected in-line it can also be enabled in normal operation
to simultaneously bypass traffic flow to the other side and direct it internally for analysis. In this
case it maintains "receive-only"-like monitoring functions, when control functionality is not
required.
The bypass card supports the following four modes:
• Bypass — The bypass mechanism preserves the network link, but traffic is not processed for
monitoring or for control.
• Forwarding — This is the normal operational mode, in which the SCE 2000 processes the
traffic for monitoring and control purposes.
• Sniffing — The bypass mechanism preserves the network link, while in parallel allowing the
SCE 2000 to process the traffic for monitoring only.
• Cutoff — There is no forwarding of traffic, and the physical link is forced down (cutoff
functionality at layer 1).
Maintaining the Network Links vs Maintaining SCE 2000 Platform
Functionality
When a single SCE 2000 is deployed, the user may decide that in case of a failure, maintaining
the network link is more important than providing the SCE 2000 functionality. In this scenario,
when the SCE 2000 detects a failure that requires a reboot process for recovering, it immediately
switches to Bypass mode, allowing all traffic to bypass the SCE 2000. The SCE 2000 stays in
Bypass mode maintaining the network link, albeit without SCE 2000 processing, until the SCE
2000 fully recovers from the failure and is ready to resume normal functioning.
Alternatively, the user may decide that the SCE 2000 functionality is sufficiently crucial to
require severing the link if the SCE 2000 platform fails. In this case, when the SCE 2000 detects a
failure that requires a reboot process for recovering, it immediately switches to Cutoff mode,
stopping all traffic flow. The SCE 2000 stays in Cutoff mode, halting all traffic, until it fully
recovers from the failure and is ready to resume normal functioning. In Cutoff the physical
interface is blocked, enabling the network device connected to the SCE 2000 to sense that the link
is down.

Physical Topologies
Physical T opologies
Following are descriptions of a number of physical topologies that the SCE 2000 supports.
Single SCE 2000 T opologies
A single SCE 2000 supports both single FE link and dual FE link topologies.
Single Link: Inline Topology
Typically, the SCE 2000 is connected in a full duplex FE link between two devices (Router,
BRAS, etc.). When the SCE 2000 is installed as an inline installation, it physically resides on the
data link between the subscribers and the network.

When configuring the SCE 2000, an inline installation is referred to as “inline” connection mode.
