摘要
提出了一种基于MPLS的IP语音网络恢复性能评估方案,该方案利用OPNETModeler工具构建一个基于MPLS的IP语音网络仿真平台,分析与评估基于MPLS的两种故障恢复技术。仿真结果表明,采用基于MPLSOAM技术的快速重路由算法可以有效地缩短流量重路由时间与改进IP语音网络服务质量,验证了基于MPLSOAM技术的FRR算法在VoIP网络系统中实现QoS性能网络优化的可行性。
This paper presented the evaluation scheme of recovery performance in VolP Network based on MPLS. It modeled a simulation platform of VolP network based on MPLS in OPNET Modeler, analyzed and evaluated two failure recovery technique based on MPLS. Simulation results show that using fast rerouting based on MPLS OAM can efficiently decrease delay of traffic rerouting and improve quality of server in VolP network, and verify that the scheme has feasibility of achieving optimization of network performance in VoIP .
