摘要:本文分析Parlay Gateway的性能。为了提高系统的时延特性,提出了按照业务对时延的敏感度进行优先级排队模型,在该模型的基础上,提出了一种实用的自适应过载控制算法,该方法旨在避免过载的同时保持系统的使用效率,提高了系统的吞吐量。之后对本文提出的方法进行了系统仿真,仿真和分析表明,该方法较目前其它的方法更加科学和完善。

Performance Analysis and Overload Control of
Abstract:This paper analyses the performance of a Parlay Gateway. In order to reduce the delay introduced by the Parlay Gateway, this paper puts forward a priority queuing model based on the latency sensitivity of applications. On the basis of this model, a kind of practical self-adaptation load control mechanism is proposed. This load control mechanism is designed to keep the Parlay Gateway works efficiently while avoiding overload as a result the throughput is raised. Simulations are used to evaluate the behavior of the load control mechanism. Some simulation and analysis prove this method is better than other overload control methods at present.
Keywords: Parlay Gateway Latency throughput load control overload control
