基于代理的广域网服务发现系统的设计

Design of proxy-based service discovery system for WAN

随着网络应用的不断发展,服务发现技术已经成为许多网络应用中的关键组成部分。现有的服务发现系统大多是为局域网设计的,在广域网环境不能有效地工作。采用基于代理的分布式体系结构,能够快速扩展系统规模,提高可用性。讨论了基于代理的服务发现系统中的主要问题,阐述了设计原则和实现方案,并且给出了一个服务发现代理服务器模型。

With the development of network application, service discovery technology has become an important part of network application. Most of existing service discovery system were designed for LAN, which couldn＇t work well in WAN, Proxy-based distribute system could expand system scale easily and improve usability, The main problem in proxy-based service discovery system was discussed.The principle of design, realizing scheme and a service discovery proxy model were presented,
