中文摘要：

为了满足LDP的一致性测试需求，并突破原有LDP一致性测试中测试方式简单、测试程序不易于理解和测试语言描述能力弱的局限，基于TTCN-3测试描述语言研究了LDP一致性测试；在自行研制的分布式并发测试系统PITSv3的基础上设计扩展了针对LDP的测试适配器模块；设计了LDP的测试集并使用TTCN-3语言实现了该测试集，从而完成了PITSv3系统对LDP的功能扩展。最后进行了PITSv3系统对于LDP的一致性测试实践。

英文摘要：

To meet the needs required by the conformity test of the LDP, and to make a breakthrough in the weaknesses that existed in the current LDP conformity test, which were characterized by the facts that the testing methods were simplistic, and that the testing programs were not easily understandable, and that the testing languages were barely descriptive, by basing the research of LDP conformity test on TTCN-3 testing description language, the paper had designed and expanded the test adaptor module for LDP, and had designed and implemented an LDP test suite using TTCN-3 language, on the basis of PITSv3, devised a distributed test system. Consequent!y, it accomplished the function expansion of LDP and implemented the LDP confortuity test practice, using PITSv3 system.
