分级预留带宽接纳策略及其公平性分析

Internet上各种应用流的飞速增加需要能够高效利用有限的网络资源的接纳控制策略。传统的接纳策略在追求高总体接纳率的同时却忽略了接纳的公平性,也就是对不同带宽需求的网络流体现出极不均匀的接纳率。出于公平性的考虑,该文提出了一种分级预留带宽接纳策略。仿真试验表明:该策略与传统的接纳控制策略相比,具有较高的接纳公平性。

A Classified and Bandwidth-Reserved Admission Control Algorithm and Analysis of its Fairness

The rapid increment of application-flows on the Internet needs an admission control algorithm,which can efficiently make use of limited network resource.Traditional admission control algorithms always pursuit high admission-ratios,while they ignore fairness,that is,the admission -ratios are very uneven when the algorithms meet with flows which have large differences in bandwidth required.Considering of the fairness,the paper presents a Classified and Bandwidth-Reserved Admission Control Algorithm.Computer-simulations show that the algorithm can come over the un-fairness,compared with other traditional algorithms.
