Cisco SCE8000 Topology and Topology-Related

Parameters

This chapter describes the possible deployment topologies of the Cisc o SCE8000 and explains how to

configure the relevant parameters correctly for each topology.

The Cisco SCE8000 Platform

The Cisco SCE8000 is a solution for dual links with load sharing and asymmetrical routing and support

for fail-over between two SCE platforms.

The Cisco SCE8000 is built to support wire speed processing of full-duplex 10GBE streams. The Cisco

SCE8000 can, therefore, be deployed in a multi-link environment, in several different topologies.

• Single Cisco SCE8000 topology — Provides the ability to process both directions of a bi-directional

flow, processing both the upstream and downstream paths of a flow, even if they traverse different

links.

• Dual Cisco SCE8000 topology (cascade) — Cascaded Cisco SCE8000s provide high-availability

and fail-over solution and maintain the line and service in case of Cisco SCE8000 failure

• Multi-Gigabit Service Control Platform (MGSCP) topology — For scalability, the Cisco SCE8000

platform supports the option to connect a multiple number of SCE platforms to a Cisco 7600 Series

router used to perform load-balancing between the platforms.

Topology Considerations

There are several issues that must be considered in order to arrive at the optimum configuration of the

topology-related parameters:
