Cisco SCE 2000 4xGBE Installation and Configuration Guide
OL-7824-04 3-1
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.
This chapter contains the following sections:
• The SCE 2000 Platform 3-1
• Topology Considerations 3-1
• Physical Topologies 3-4
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 2000s provide high-availability and
fail-over solution and maintain the line and service in case of SCE 2000 failure.
Topology Considerations
There are several issues that must be considered in order to arrive at the optimum configuration of
the topology-related parameters:
• Functionality — Will the system be used solely to monitor traffic flow, with report
functionality only, or will it be used for traffic flow control, with enforcement as well as
report functionality?
