摘要: 在服务消费过程中,为保证可用性和服务质量,需对服务调用请求实施失效监控和透明失效接管,而基于服务端集中式代理的监控与接管方式容易引起服务端过载,致使服务系统的整体可用性和服务质量下降。针对该问题,提出一种基于客户端代理的透明服务接管方案,以分布式、基于服务描述自动生成的客户端代理取代集中式的服务端代理。该方案在解决集中式代理过载问题的同时能够保证较高的开发效率。

Abstract: In service oriented architecture, transparent service take-over is the main method of reducing the probability of dissatisfaction of service requesting from the consumer when the service is unavailable. For the purpose of transparent service take-over, the client-side and proxy-based approach can avoid the situation of the whole system service availability decreasing, which is probably caused by overloading when using the centralized one on the server side. In the client-side and proxy-based approach, automatic generation of proxy source code from service description can obviously improve the efficiency and decrease the difficulty of the developing process.

Key words: proxy, transparent, service take-over, client side
