More than ever before, service providers need visibility into application and subscriber usage patterns, and the capability to manage network bandwidth and to expand and differentiate their service offerings. The Cisco SCE 8000 is designed for carrier-grade deployments that require high-capacity stateful application and session-based classification and management of all IP network traffic. Powered by a patented architecture that employs hardware acceleration with multiple high-speed RISC processors, the Cisco SCE 8000 is the powerhouse of the Cisco Service Control Engine product family. Its highly programmable core can track and manage up to 32 million concurrent unidirectional application sessions over an IP network. The Cisco SCE 8000 is very extensible and scales to meet capacity and performance requirements of IP Next-Generation Networks (NGNs).
The Cisco SCE 8000 may be deployed in a number of capacities within today's service provider networks. It can be integrated into the core, at aggregation peering-points, and at the edge to provide advanced application-level bandwidth optimization, management, and service control functions. The Cisco SCE 8000 is access-independent and can be deployed in any cable, wireline, or mobile IP network environment. The Cisco SCE 8000 is deployed using high-speed 10-gigabit Ethernet interfaces connected to the core, aggregation, and edge elements of today's service provider networks.
Residing at these critical junctions of the network, the Cisco SCE 8000 is not only a high-performance solution, but also a highly available and robust solution. It employs a number of high-availability and reliability features to meet the expectations of today's most demanding multimedia applications and service-level agreements (SLAs). The Cisco SCE 8000 employs both inter- and intra-chassis redundancy features to help ensure high availability. Multiple Cisco SCE 8000s can be deployed to achieve high availability and failover without imposing any single point of failure. An N+1 high-availability topology is supported by clustering multiple Cisco SCE 8000s, allowing the solution to scale linearly. To achieve higher performance and maximum capacity, the Cisco SCE 8000 takes advantage of patented system logic and stateful Deep Packet Inspection (DPI) technology.
This solution provides stateful protocol monitoring to help detect and manage virtually any IP network application, including but not limited to: web browsing, multimedia streaming, and peer-to-peer (P2P). The Cisco SCE 8000 permits service providers to optimize application-level traffic, resulting in an overall reduction of network congestion and associated network capacity upgrades. The Cisco SCE 8000 enables carriers to gradually scale their network, starting with a single processing card and growing to a multiple-chassis solution.
Cisco Service Control solutions analyze the payload of individual packets using stateful DPI at Layer 3-7. The Cisco SCE 8000 uses customized ASICs and hardware acceleration to help ensure carrier-grade performance with the capacity to support two or four 10-gigabit links per chassis and up to 32 million unidirectional flows.
The Cisco SCE 8000 serves as the foundation for Cisco's DPI solution for multi-gigabit and multi-10-gigabit speeds, making Cisco the industry leader in DPI technologies for today's service provider IP NGNs.
Stateful deep packet inspection
Instead of processing packets as individual events, the Cisco SCE 8000 fully reconstructs individual traffic flows and the Layer 7 state of each individual application session. By maintaining state information, the Cisco SCE 8000 readily identifies applications that employ dynamically assigned port numbers, and tracks applications that involve multiple inter-related or spawned flows commonly found in voice-over-IP (VoIP) or multimedia streaming protocols. The Cisco SCE 8000 applies rules as part of controlling the admission policies or session characteristics of a data flow.
The Cisco SCE 8000 is programmable and extensible, and therefore can readily adapt to new protocols and IP traffic-management requirements. SML, a programming language specifically developed for service delivery, can adapt the Cisco SCE engines to the dynamic requirements of application-level analysis and traffic optimization while enabling the system to identify and manage complex protocols such as Session Initiation Protocol (SIP), Real Time Streaming Protocol (RTSP), and obfuscated P2P protocols.
Integration and management
The Cisco SCE 8000 Service Control Engine integrates with existing network infrastructure, management, provisioning, operation, and support systems using industry-standard APIs.
