Conformance testing for IS-IS protocol based on E-LOTOS

With the development of Internet, effective and steady routing protocol has become an important factor which ensures the network performance . And scientific researchers have been pay much attention to testing on routing protocol conformance test on IS-IS protocol is studied, which is one of the main Internal Gateway Protocols (IGPs). Moreover, the adjacency state machine of the protocol is improved. And the IS-IS protocol abstract test suits are described in TTCN-3. The executable test cases of IS-IS protocol are given. Finally, Conformance test on IS-IS protocol is implemented in the environment of Quagga-0.99.7 in Linux and the test results are analyzed.
