Introduction
This chapter describes the possible deployment topologies of the SCE 2000.
The Cisco SCE solution offers a number of basic topology options that permit the user to tailor the SCE
platform to fit the needs of a particular installation. An understanding of the various issues and options
is crucial to designing, deploying, and configuring the topology that best meets the requirements of the
individual system.

The SCE 2000 Platform
The SCE 2000 introduces a solution for dual links with load sharing and asymmetrical routing and
support for fail-over between two SCE platforms.
The SCE 2000 supports wire speed processing of full-duplex 2-Gigabit Ethernet streams. The SCE 2000
can, therefore, be deployed in a multi-link environment, either in a single or dual SCE platform topology.
•
single SCE 2000 topology — Provides increased network capacity and 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 SCE 2000 topology (cascade) — cascaded SCE 2000 s provide high-availability and fail-over
solution and maintain the line and service in case of SCE 2000 failure.
