1. A computer-implemented method for detecting locations of network failures, the method comprising:

  • representing a network using a beta likelihood function;

    measuring a packet transfer rate across each of a plurality of network paths in the network, wherein each one of the plurality of network paths includes at least two nodes and at least one link;

    for at least one path among the plurality of network paths, determining a respective packet transfer rate for each of the at least two nodes and the at least one link included in the at least one path by updating estimated beta parameters of the beta likelihood function for each of the at least two nodes and the at least one link; and

    determining at least one location for at least one network failure based on the determined respective packet transfer rate for each of the at least two nodes and the at least one link included in the at least one path.
