一种基于Aglet的Web服务事务协调框架

A Coordination Architecture of Web Service Transaction Based on Aglet

本文针对Web服务事务协调环境的特点,提出了一种基于移动代理思想的事务协调框架。该框架采用了一种面向Web服务的新型事务模型THP作为事务代理的协调策略,并通过引入"事务意识",进一步增强了代理进行事务协商的智能性。此外,文中还给出了这两种事务协调算法在IBM Aglet平台下的具体实现,并通过实验与仿真显示了该事务协调框架的优越性能。

This paper presents a new framework based on mobile agents for the Web Services transaction coordination environment. It adopts a transaction model THP as the coordination strategy for the agents,in which a new idea of “transac- tion awareness” is introduced to enhance the intelligence of the agents during the negotiation. Furthermore, a comparison of two coordination algorithms is carried out in the implementations on the IBM Aglet platform. Through the simulations, it can be concluded that the proposed protocol is provided with better efficacy of the transaction coordination.
