服务质量参数公式的选择对ATM网络资源利用率的影响

The influence of selecting QOS parameter formulae on utilization of ATM network resource

文中基于信元丢失率讨论了ＱＯＳ参数公式选择对ＡＴＭ网络资源利用率的影响，用对比的方法说明了在保证服务质量的前提下，选择优化的ＱＯＳ参数公式提高资源利用率的可行性；提出了乐观性资源分配策略避免ＱＯＳ降级的建议，并展望了为提高资源利用率应作的 ＱＯＳ研究工作。

Based on Cell Loss Rate (CLR), the influence of selecting QOS parameter formulae on the utilization of ATM network resource is discussed in this paper Comparison shows the feasibility of achieving high utilization of network resource while satisfying user's QOS requirements by selecting efficient formulae for QOS parameters. When using optimistic policy of resource allocation, a new idea of avoiding QOS degradation is suggested. Finally, future works about QOS and utilization of network resource are proposed.
