Improvement of Bandwidth Allocation Based on Cost

Abstract

Abstract: This article compares two methods of bandwidth which are equal division and cost-based allocation under the scheduling mechanism of WF~2Q, and improves the second according to fluid flow model, the result of simulation indicates it improves the utilization of resource and decreases the probability of block.

摘要： 比较了在ＷＦ~２Ｑ调度机制下平均分配和基于代价的带宽分配算法，根据流体流模型对后者提出了一种改进算法，模拟结果表明能提高资源利用率，降低阻塞概率。
