Introduction
This chapter describes the possible deployment topologies of the Cisco SCE8000 GBE and explains how
to configure the relevant parameters correctly for each topology.

The Cisco SCE8000 GBE Platform
The Cisco SCE8000 GBE is a solution for multi Gigabit Ethernet links with load sharing and
asymmetrical routing and support for fail-over between two SCE platforms.
The Cisco SCE8000 GBE is built to support wire speed processing of full-duplex Gigabit Ethernet
streams. The Cisco SCE8000 GBE can, therefore, be deployed in a multi-link environment, in several
different topologies.
• Single Cisco SCE8000 GBE 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 GBE topology (cascade) — Cascaded Cisco SCE8000 GBE s provide
high-availability and fail-over solution and maintain the line and service in case of Cisco SCE8000
