一种基于多M／M／m／m＋M排队系统的分散型云计算建模方法
A Performance Modeling of Decentralized Cloud Computing Based on Multiple M/M/m/m+ M Queuing Systems
摘要
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 aban-donment rate ,since waiting service requests are overflowed at a certain abandonment probability .The abandonment probability is in-troduced 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 perfor-mance improvement of the multiple queuing systems is testified by the numerical simulation under admission control based on aban-donment rate .关键词
