Abstract:
1. A method for analyzing an availability of at least part of a communications network, the network including a set of network components, the network component set being further divided into at least first and second subsets of network components, and each of the first and second subsets comprising a plurality of different components in the network component set, comprising: (a) determining a first traffic flow associated with the first subset; (b) determining a second traffic flow associated with the second subset, the first and second traffic flows being unequal; (c) determining a first downtime associated with the first subset, wherein the first downtime is derived from at least one of Mean Time Between Failures, Mean Time to Recover/Repair, Mean Time to Failure, Failure in Time Rate, Mean Time between Outages, failure rate, a reportable outage, an outage downtime measure, and a downtime measure for a partial outage; (d) determining a second downtime associated with the second subset, wherein the first downtime is derived from at least one of Mean Time Between Failures, Mean Time to Recover/Repair, Mean Time to Failure, Failure in Time Rate, Mean Time between Outages, failure rate, a reportable outage, an outage downtime measure, and a downtime measure for a partial outage; and (e) determining a future availability for the network component set, wherein the future availability is a function of the first downtime and first traffic flow and the second downtime and second traffic flow.
