Programmability is required for new services to be deployed quickly, and it 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 a 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 & 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
