摘　　要：测试传输在很大程度上影响测试系统实现和测试集设计.良好的传输方法能够对测试集设计者屏蔽被测协议实现的相关信息,同时简化测试配置.根据测试集设计和测试传输分离的思想,采用通信实体和网络接口相结合的机制实现测试传输,网络接口用于定义逻辑测试接口的类型和相应的参数,相当于一台逻辑测试器;通信实体用于向逻辑测试器屏蔽下层服务提供者的类型,完成测试数据的发送／接收工作.该传输机制在IPv6协议一致性测试系统中获得了成功.Transport mechanism can influence test system implementation and test suite design. Good transport mechanism can shield the information of implementation under test (IUT) to test suite designer and simplify test configuration. Based on the idea that test suite design and test transport be independent, the technique that combines communication entity with network interface is proposed to implement transport mechanism. The logical test interfaces are defined by network interfaces. The test packets are received/sent by communication entity, which makes the lower service provider transparent to test suite. Manual configuration isn' t necessary before testing. By setting appropriate identifier information in the object of network interface, the concurrent test ability of test system is independent of system configuration. It is successful to apply the transport mechanism to IPv6 protocol conformance testing.
