基于TTCN-3的CoAP一致性测试

CoAP conformance testing based on TTCN-3

协议一致性测试是确保协议实现与协议标准相一致的重要保障,有助于协议实现的进一步完善。CoAP(constrained application protocol)即受限应用协议是特别为受限节点和受限网络设计的通用应用层协议。CoAP目前仍处于草案阶段,对CoAP进行了分析,并基于标准化测试语言TTCN-3设计实现了CoAP一致性测试系统,并使用该系统对CoAP实现进行了测试。

Protocol conformance test is of great importance in making sure that the protocol implementations conform to the protocol specification, thus helps protocol implementer to improve the implementations. CoAP(constrained application protocol) is a generic Web application specified for constrained nodes and constrained network which is currently an Internet draft. A CoAP conformance test suite based on TTCN-3, a standardized testing language, was designed, implemented and used after analyzing the protocol.
