Topology; Issues To Be Considered - Cisco SCE 1000 Installation And Configuration Manual

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.

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?
