Abstract

In order to test provisioned data and functionality of a network, the operations personnel input data via an operations interface to an originating network element. The originating network element constructs a test query based on the data and selects a receiving network element to be tested. When the originating network element sends the test query to the receiving network element, the test query is processed as if it is a normal network query. A response to the test query is returned to the originating network element and reported to the operations personnel. The reported response contains not only the test results of the provisioned data in the receiving network element but also the routing functionality of the network.
