Abstract:
1. A computer readable storage media encoded with computer executable instructions, executed by a processor to perform operations comprising: selecting one or more of a plurality of fault types for inclusion in a fault set; providing the fault set and network settings obtained from a real network as inputs to a first iterative network simulation, wherein the network setting include data that is selected from the group consisting of: acquiring an estimation of network performance from the first iterative network simulation; determining a difference between the estimation of network performance and an actual observation of network performance of the real network; determining whether the difference between the estimation of network performance and the actual observation of network performance of the real network is greater than a corresponding threshold during an initial fault diagnosis; in an event the difference between the estimation of network performance and the actual observation of network performance of the real network is not greater than the corresponding threshold: in an event the difference between the estimation of network performance and the actual observation of network performance of the real network is greater than the corresponding threshold: wherein, the second iterative network simulation utilizes the new fault candidate added to the fault set to determine whether the expected performance of the network is converging with the real performance of the network.
