ABSTRACT:
A device associated with a transport network generates a first traceroute through the transport network, and monitors a performance measure associated with the transport network. The device also compares the performance measure to a criterion, and determines degradation in the transport network when the performance measure matches the criterion. The device further generates a second traceroute through the transport network when the degradation occurs in the transport network, where the first and second traceroutes are used to determine a source of the degradation in the transport network.
