Introduces metric optimization tools for improving network core metrics, maximizing throughput across routes under various failure scenarios, and resolving local congestion with minimal changes using tactical metric optimization.
Metric optimization is a Cisco Crosswork Planning tool that
-
optimizes metrics in the network core, and
-
replaces the IGP metrics of core interfaces in a network plan with new metrics chosen to maximize the throughput achievable by the resultant routes, under a specified set of failure scenarios.
The Tactical metric optimization tool lets you quickly fix local congestion by doing as few modifications as possible on selected interfaces to push utilizations under a given level.
The core of the network must be connected, and all nodes must be contained in one AS. That is, there must be a path between any two core nodes that passes only through other core nodes in the same AS, and not through edge nodes. If this is not the case, Metric optimization signals an error.
