摘要
区分服务模型作为一种重要的网络服务质量模型正逐渐受到重视,但它也存在带宽共享的公平性问题。不同于现有成果中的专注于流聚焦内部微流之间的公平性,提出应该更重视流聚集之间的带宽共享公平性,着重讨论了具有不同目标速率和不同微流数量的流聚集之间的公平性问题,同时用NS2仿真验证这种不公平性问题的存在并对结果进行分析比较,最后对在区分服务中设计公平拥塞控制机制提出一些建议。
DiffServ, an important network model and getting increasing attention, suffers for being unable to gain the fairness of resource sharing due to different aggregated traffics with different parameters. The fairness of bandwidth sharing among aggregated traffics with different target rate and number of microflow is focused on, and several available suggestions are put forward after the fairness is validated by the simulation result with NS2.
