Service Control Capabilities

At the core of the Cisco Service Control Platform stands the purpose-built network hardware

device: the Service Control Engine (SCE). Implementing a complete Service Control solution

requires that the Service Control Engine provide certain functionalities and capabilities. The

following are the core capabilities of the Cisco Service Control Engine, which support a wide

range of applications for delivering Service Control solutions:

• 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 platform, and

enforcing the appropriate policy on this subscriber traffic.

Subscriber awareness is achieved using dedicated integrations with subscriber

management repositories, such as a DHCP or a Radius server.

• Application awareness: The ability to understand and analyze traffic up to the application

protocol layer (Layer 7).

For an application protocol that is 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.

• Stateful, real time traffic control: The ability to perform advanced control functions, including

granular BW metering and shaping, quota management and redirection, utilizing 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 SML language.

Programmability means that new services can 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 3rd party

systems at the Service Provider, such as provisioning systems, subscriber repositories, billing

systems, and OSS systems. The Service Control Engine 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 execute all operations described

above at wire speed.
