  • Patent number: 8243621
    Abstract: An apparatus and method for verifying route and bandwidth settings of multiple services provided over networks. The apparatus has an extractor and a verifier. Based on input data describing services each having primary and secondary routes between specific locations, an available bandwidth of each network, and a guaranteed bandwidth of each service, the extractor selects a first network to be verified and extracts first services that use the first network as their respective primary routes. The extractor then selects at least one second network from among the networks that the first services specify as their respective secondary routes. The extractor extracts second services that use the second network as their primary routes and specify the first network as their secondary routes. The verifier sums up guaranteed bandwidths that the first and second services should provide, and determines whether the sum is smaller than an available bandwidth of the first network.
