| 摘 要： | 提出一种区分服务机制,建立基于被动侦听的服务性能(QoS)反馈控制方法,可以实现接纳请求的优先级调度方案.系统中监测终端的核心是基于简单网络管理协议(SNMP)的侦听机制,区分服务控制策略的核心内容是优先级队列调度,控制策略所使用的参数都可以根据实际环境动态调整.实验室条件下的测试结果表明,当发送速率达到每秒90个请求时,使用拥塞控制策略的服务器能保持比较好的性能.在复杂环境下,反馈控制系统对请求的用户实现区分服务,提高和改善服务器的服务性能,具有一定的适应性与鲁棒性.

| Abstract: | In this paper a differentiated services(DS) mechanism for quality of services(QoS) feedback control method based on passive listening is proposed.In the system,the core of monitor terminal is the passive listening based on the simple network management protocol(SNMP) and the core of the differentiated services control is the priority queue.All control parameter can be chosen according to the environment.The simulation results show that the server with congestion control strategy maintains considerable performance while the sending rates approach 90 per second.In complex context,the feedback system is robust to realize DS and improve server performance. |
