Oxedit - better metrics

What are metrics?

Metrics are used to determine whether one route should be chosen over another. The routing table stores possible routes, while link-state or topological databases may store all other information as well. For example, Routing Information Protocol uses hopcount (number of hops) to determine the best possible route. The route will go in the direction of the gateway with the lowest metric. The direction with the lowest metric can be a default gateway.

A Metric can include:

  1. path reliability
  2. path bandwidth
  3. throughput [SNMP - query routers] Router metrics are metrics used by a router to make routing decisions. It is typically one of many fields in a routing table.
