Cisco Systems SCE 2000 4/8xFE manual The SCE Platform

Chapter 1 General Overview

The SCE Platform

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:

•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
