ABSTRACT:
There is disclosed a method for scheduling verification tests to audit routing information in a packet switching network comprising a plurality of packet switching nodes and a plurality of bi-directional links each interconnecting a distinct pair of said nodes. The method involves the operation system of the telecommunications management network selecting when to schedule verification tests of routing tables in the network. The operation system selects a test time duration period for scheduling all the verification tests to be run on the network. The operation system further selects the number of nodes to be tested and determines sub-tests to all destination nodes frown each node in the network to be tested. The operation system then selects a time test interval based or the quotient of the scheduled test time duration period and the total number of tests to be conducted. Verification tests at each node are then scheduled by the operation system by spacing the start up time for each test at each node by the time test interval. The method for scheduling routing verification tests of the present invention has the advantage in that it disperses the load induced on the network by running these verification test at spaced apart time intervals over a test time frame so as to ensure that a minimal number of verification tests are run at any one time in the network.
