Cisco SCE 8000 Platform Topologies

The Cisco SCE 8000 platform is an ideal solution for dual links with load sharing and asymmetrical routing and support for
fail-over between two Cisco SCE platforms.
Cisco SCE 8000 is built to support wire-speed processing of full-duplex 10 GBE streams. The Cisco SCE 8000 can, therefore,
be deployed in a multilink environment, in several topologies:
• Single Cisco SCE 8000 topology—Enables processing of both upstream and downstream paths of a bidirectional flow, even
if these paths traverse different links.
• Dual Cisco SCE 8000 topology (cascade)—Provides high-availability and fail-over solution, and maintains the line and
service in case of Cisco SCE 8000 failure.
• Multi-Gigabit Service Control Platform (MGSCP) topology—Provides scalability. The Cisco SCE 8000 platform supports
the option to connect multiple SCE platforms to a Cisco 7600 Series Router to perform load balancing between the
platforms.

Physical Topologies

These are the descriptions of the physical topologies that Cisco SCE 8000 supports:

Single Cisco SCE 8000 Topologies
A single Cisco SCE 8000 supports both single 10GBE link and dual 10GBE link topologies.

Single Link: Inline Topology
Typically, Cisco SCE 8000 is connected in a full-duplex 10GBE link between two devices (Router, broadband remote access
server, and so on). When Cisco SCE 8000 is installed inline, it physically resides on the data link between the subscribers and
the network (see Figure 3).
