Abstract

A system for analyzing an availability of at least part of a communications network is provided. The network includes a set of network components, that are further divided into first and second subsets of network components. Each of the first and second subsets includes a plurality of different components in the network component set. The system includes an availability prediction assessment tool that is operable to (I) determine a first traffic flow exchanged between first and second endpoint groupings in the first subset, the first traffic flow being a first percentage of a total traffic flow in the communications network; (ii) for a plurality of first subset members involved in the first traffic flow, determine a corresponding downtime; (iii) determine a total of the downtimes corresponding to the plurality of first subset members; (iv) multiply the total of the downtimes by the first percentage to provide a first traffic weighted total downtime for the first subset; and (v) determine an availability of the first subset for the first traffic flow based on the first traffic weighted total downtime for the first subset.
