Abstract: As a formal description language for test suite, TTCN is widely used in test. After a brief introduction on the basic concept of concurrent TTCN, it comes to the operational semantics of TTCN2 and the corresponding algorithm, finally proposes the scheduling algorithm of parallel test components.
