Cisco Service Control Capabilities Chapter 1 General Overview 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 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). Programmability allows new services to be deployed quickly and provides an easy upgrade path for network, application, or service growth.

General Overview
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
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).
Programmability allows new services to be deployed quickly and provides an easy upgrade path for
network, application, or service growth.
