一种动态带宽分配策略及其性能分析
Strategy of Dynamic Bandwidth Allocation and Its Performance Analysis
摘要
Abstract
Aiming at Quality of Service(QoS) requirements of different traffics in the current network, a dynamic bandwidth allocation strategy named E-DBA is proposed by taking into account both the traffic priority and system load. Geom/G/1 queuing model with multiple working vacations mechanism is established. By using the method of embedded Markov chain, the steady-state measures of the queueing model are derived. The performance measures in terms of the average response time and system utility of E-DBA are given. With experiments, the influence of the guaranteed bandwidth of class II traffic on the system performance is illustrated.关键词
