ABSTRACT:
There is disclosed a method for auditing routing information in a packet switching network. One method involves utilizing the telecommunications management network to sample through a general purpose management interface routing table information at live nodes in the operating network for a test message sent from a test initiator node to a final destination node through intermediate nodes. The telecommunications management network subsequently runs verification tests on the collected routing table information apart from the packet switching network. This method has the advantage that the verification test is not run on the network while still testing actual table routing information. Advantageously, this method tests actual routing information without overloading the network with additional routing requests provided by the test. Moreover, this method does not induce any load on the network. Further, this method uses data collected in real time from the network.
