Topology

This chapter describes the possible deployment topologies of the SCE 1000. 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:

Issues to Be Considered

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?

Physical installation configuration — Will the SCE Platform be installed as inline? Or will the SCE Platform use an optical splitter?

Redundancy — Must the system be designed to guarantee uninterrupted service? If so, there must be a backup SCE Platform to assume operation in case of failure of the primary data link.

Link failure and recovery — How should the SCE Platform respond to platform failure and subsequent recovery? Should traffic flow continue even though the unit is not operating, or be halted until the platform is repaired/replaced? Should the unit actually resume operation when it is again operational?
