摘要

基于Erlang-A同Erlang-C相结合的排队系统模型

由多云域组成的分散型云计算被抽象为多排队系统.基于丢弃率参数实现了对延迟敏感服务请求的准入控制

等待的服务请求以一定的丢弃概率被溢出.将丢弃概率引入Riordan公式

在Hayward近似中提出基于空间随机过程的汇聚溢出流渐进峰度因子

利用等效随机理论研究了溢出流丢失问题.通过仿真实验验证了基于丢弃率准入控制下多排队系统的性能提升.

Abstract

Based on Erlang-A and Erlang-C

a decentralized cloud computing system composed of multiple cloud domains is simplified to multiple queuing systems.The admission control of delay-sensitive service requests can be implemented based on abandonment rate

since waiting service requests are overflowed at a certain abandonment probability.The abandonment probability is introduced into Riordan Formula

while the asymptotic peakedness factor of aggregate overflow based on spatial stochastic process is introduced into Hayward's approximation.The overflow loss performance is studied using equivalent random theory.The performance improvement of the multiple queuing systems is testified by the numerical simulation under admission control based on abandonment rate.
