基于多层集群架构的自适应过载控制机制

Self-adaptive overload control mechanism for clusters with multi-tier architecture

提出一种自适应的过载控制策略,预先不需要知道任何负载信息,不需要关键属性的人为调节,根据接纳率与响应时间的动态关系进行自适应调节,更好地保证了服务水平协议,缩短了响应时间,优化了系统资源。

This paper contributed a self-adaptive overload control （SAOC） mechanism, which did not require any prior information on the incoming traffic or manual configuration of key parameters. The monitor module took measures to analyze the relationship between the observed response time （RT） and the rate of admitted sessions. SAOC mechanism guarantees better service level agreements, shortens the response time, self-optimizes the resource utilization rapidly.
