摘要
分析了当前网络中保证服务质量的机制,针对目前MPLS本身的服务质量只支持区分服务的现状,提出将动态分组状态模型用于MPLS的方法,通过将状态信息封装在MPLS分组的二层标签中,使核心网络在不需保存每流状态的情况下提供基于每流的服务质量,详细阐述了该方案的总体结构、数据平面和控制平面等,并通过在ns中模拟分析对该方案进行了验证。
Mechanisms of guarantee QoS currently are analyzed in this paper.Because MPLS only supports Differentiated Services,the solution is proposed by introducing dynamic packet state to MPLS network.By encapsulating state information in an extra label of MPLS packet,per-flow QoS is guaranteed without state maintained in core network.The architecture,data plane and control plane are illuminated.Finally,simulation results are given and the approach is testified.
