摘要
首先介绍了SQL Remote复制技术及其消息代理,然后针对其固定时间的消息轮询策略的不足提出了一种基于修改频率的消息轮询策略,并且给出了相应的算法,从而改进了消息代理发送消息的方式。通过实验证明,这种基于修改频率的消息轮询策略较大地减轻了消息代理和邮件系统的负担,较好地解决了因固定时间的消息轮询策略的不足而产生的问题。
At first , this paper introduces SQL Remote replication technology and message agent. Then direct against the defi- ciency of the tactics which inquiry message on the regular time, the tactics which inquiry message based on modification frequency is put forward, and the corresponding algorithm is also provided, and the way that message agent send message is improved. The experiment proves that this tactics greatly lights the burden of message agent and mail system. The tactics bitterly solves the problem which produced by the deficiency of the tactics which inquiry message on the regular time.
