【摘要】 TTCN作为一种形式化的测试集描述语言，已经得到了广泛的应用。在介绍了并发TTCN的基本概念之后，接着介绍TTCN2的操作语义及相关算法，然后结合TTCN执行机的实现给出了并发测试组件的调度算法。更多还原

【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.更多还原
