基于对等架构的Web服务注册系统

Peer-to-peer based Web service registration system

针对传统的集中式架构的Web服务注册系统存在性能瓶颈、单点故障的问题,设计并实现了基于结构化对等协议的Web服务注册系统。系统包括配置、调度分发、对等通信、权限验证、JUDDI和网络资源监控等六大模块,提出了基于Pastry的服务注册系统调度和通信算法,设计了相应的Web服务注册和发现的流程,采用SoapUI和LoadRunner对系统进行测试。实验结果表明,该系统能够支持大规模服务请求,具有动态可扩展性,在模拟多并发实验中,服务注册和发现的响应速度都提高了1倍。

Since the traditional centralized architecture Web service registry system suffers from such problems as performance bottleneck, single-point-of-failures, a structure Peer-to-Peer （P2P） based Web service registry system was designed and implemented. The registry system consists of six modules including configuration, schedule and distribution, peer-to-peer communication, rank validation, JUDDI, and network resources monitoring. The pastry based system scheduling and communication algorithms were proposed, and the corresponding Web service registration and discovery process was designed. The Web service registration system was tested and analyzed using SoapUI and LoadRunner. The experimental results show that the system can support large-scale accessing and has dynamic scalabitity. In the multi-concurrent simulation experiments, the response soeeds of Web services registration and discovery are increased 1 times.
