The Cisco SCE 1000 series Service Control Engine is a network element specifically designed for carrier-grade deployments requiring high-capacity stateful application and session-based classification and control of application-level IP traffic per subscriber.The Cisco SCE 1000 series Service Control Engine is designed for carrier-grade deployments that require high-capacity stateful application- and session-based classification and control of all network traffic. Powered by a patented architecture employing hardware acceleration and multiple high-speed Reduced Instruction Set Computer (RISC) processors, the Cisco SCE 1000 series is a key component of the Cisco Service Control technology solution. It is a high-performance, purpose-built traffic metering and control device with a highly programmable core that can track and manage up to 2 million concurrent unidirectional application flows over an IP network. This extensible network element is specifically designed for scalable control of application flows.The Cisco SCE 1000 series in high-performance metropolitan-area (metro), cable, DSL, mobile, or Wi-Fi networks provides advanced application-level bandwidth optimization, management, and service control functions. The Cisco SCE 1000 series resides at the network edge, where aggregation access devices connect to the Internet backbone infrastructure.
