摘要：

为选择合适的补偿服务，提出基于补偿因子的Web事务QoS框架。将事务协调中的补偿成本和补偿可靠性作为一种QoS扩展，事务协调者基于已建立的QoS规则库进行事务选择和恢复，从而提高事务整体QoS属性，满足事务请求的QoS需求。实验结果表明，该框架可降低Web事务的补偿成本，提高Web事务的成功率。

Abstract:

In order to select suitable compensation service, this paper presents a Web transaction Quality of Service(QoS) framework based on compensation factor. It makes compensation cost and reliability of transaction coordination as a QoS extension. Transaction coordinator is based on built QoS rule base to progress transaction selection and restore. It can enhance transaction whole QoS attribute and satisfy QoS requirement of transaction request. Experimental result shows that this framework can reduce compensation cost of Web transaction, and enhance success rate of Web transaction.

Key words: Quality of Service(QoS), Web transaction, compensation factor Quality of Service(QoS), Web transaction, compensation factor
