Circuit Manager Overview

Circuit Manager Overview

A circuit is defined as a path of glass that carries one or more wavelengths of light along the path. You can use Circuit Manager to view and manage circuit information by creating and editing circuits associated with an end-to-end path in the fiber network.

You can use Circuit Manager to define and edit circuits along a connected path.

Dirty Circuits and Enhanced Circuit Management

Enhanced Circuit Management refers to the ability of Fiber Manager to heal (re-path) circuits that are broken by any network connectivity changes made in Connection Manager. Connection Manager attempts to execute the circuit healing process when you close it.

Broken circuits are referred to as "dirty" circuits. Dirty circuits are those circuits whose stored path in the database are different than the path traced by Fiber Manager. For example, if an existing circuit is broken via the re-routing of its path, the circuit might follow either of two possible routes. Such a circuit is invalid and is therefore considered dirty.

When you create a new circuit in your network, Fiber Manager automatically populates its circuit header information. This header information supplies the identifying data (a point on the circuit unlikely to change) required for Fiber Manager to automatically heal that circuit should connectivity later change.

Circuits that existed prior to Fiber Manager 10.1, on the other hand, require you to take action in order for Fiber Manager to automatically manage their future repair. This involves using Circuit Manager to populate the necessary header information.
