| 摘 要： | 为给并发访问的多个请求提供QoS保证，Web Service必须借助某些算法对请求加以控制。该文分析QoS延时参数的构成，提出基于QoS延时参数的服务接纳控制算法。该算法可在满足既有服务的QoS延时要求的条件下，控制接纳新进入的服务。否则即让其在队列中等待直到被服务器接纳，或服务器直接抛弃这个请求，由客户端在超时后自动重发请求。

| Abstract: | To promise QoS of the many coinstantaneous requests in the Web Service, it needs some control algorithms to control the requests. This paper analyzes structure of delay parameter of QoS and brings forward a service admission control algorithm satisfied with requirement for service delay parameter. The algorithm judges whether server can accept the new request in the condition that can promise the delay parameter of QoS for the running services in the server, otherwise server refuses the request, and then assigns the request waiting in the line or discards this request directly and let the client requests again after the time-out be elapsed. |
