摘要
服务质量(QoS)和流量工程(TE)是在当今网络中提供实时应用业务的两种重要技术。多协议标记交换(MPLS)在IP网QoS提供和TE功能实现中起了关键作用。首先介绍了区分服务感知的流量工程(DS-TE),然后提出了一种基于DS-TE的网络流量分配新方法。给出了相关的数学模型,并进行了相应的仿真,仿真结果表明使用该方法实施DS-TE时,在满足不同业务的QoS同时能较好地均衡网络负荷。
Quality of Service (QoS) and Traffic Engineering ( TE ) capabilities are two important techniques in today's networks for supporting real-time applications. Multi Protocol Label Switching (MPLS) plays an important role in IP networks for providing QoS and TE features. In this paper, A DiffServ-aware Traffic Engineering (DS-TE) is firstly introduced. Then a new method to allocate network traffic based on DS-TE is proposed. The mathematical model and simulation of the method are given too. The simulation results show that the proposed method can balance the network load and satisfy the QoS of different services.
