Based On Ttcn 3 Diameter Protocol Codec Design And Implementation

Protocol conformance test is an important means that can ensure the protocolimplementation correctly.TTCN-3test language is similar to other commonly usedhigh-level programming language, it contains the general senior language commonlanguage characteristics and also includes a series of tests of the structure of languageand special language object,such as concurrent test components, template matchingmechanism, timer processing, test execution control, synchronous/asynchronouscommunication function and so on. These can make it has stronger ability about thedescription and the more widely generality, in order to adapt to the new softwarearchitecture and the next generation network protocol testing needs.This paper proposes a TTCNs-based Diameter protocol codec design scheme,which is based on TAU/Tester platform of Telelogic company, to send or receive thedata from the test platform to the SUT (system under test) correctly.
