提出与描述了适合大规模因特网环境的对等网络服务网格平台PSGP(P2P-based Service Grid Platform)的设计、实现与性能评测.PSGP平台结合了对等网络技术、网格的Web Services技术、面向服务的框架技术,使得PSGP平台具有非集中性、可扩展性、互操作性与鲁棒性好的优点.使用对等网络的JXTA协议完成对等实体的组织、资源发现、服务调用的功能.通过设置对等实体的衔级、安全的认证机制等高级技术保证了平台的安全性与可信任机制.并行应用的案例测试表明,PSGP在对等实体的通信轮回时间、应用的吞吐量上,具有较好的性能,可以作为实现大规模的分布式模拟的可行方案.
This paper presents and describes the design, implementation and performance evaluation of peer-to-peer service grid platform (PSGP) suitable for large-scale Internet environment.PSGP platform combines peer-to-peer network technology, Service-oriented framework technology makes the PSGP platform have the advantages of decentralization, scalability, interoperability and robustness.JXTA protocol using peer-to-peer network completes the functions of peer entity organization, resource discovery and service invocation The security and trustworthy mechanism of the platform are ensured by setting advanced technology such as the peer level of peer entity, secure authentication mechanism, etc. The case tests of parallel applications show that PSGP has better performance in terms of communication round-robin time and application throughput , With good performance, can be used as a viable solution for large-scale distributed simulation.
