摘要
针对VoIP(Voice over IP)不保证QoS(Quality of Service)的问题,分析了MPLS(Multipro-tocol Label Switching)网络可用来改进数据包上的话音业务的优点,利用MPLS的LSP(Label Switched Path)的承载能力可以为话音包的传送提供可靠的QoS保证,对其进行实验仿真。仿真结果表明,VoMPLS(Voice over MPLS)为话音业务提供了一个比VoIP更可靠有效的承载网络,使话音业务符合QoS的要求。
Since the VolP（ Voice over IP） can not guarantee service quality of service,the paper analyses the advantage that the MPLS （Muhiprotocol label switching） network can improve voice traffic in data package, and makes use of the feature that the carrying capability of LSP（ Label switched path） in the MPLS can provide reliable quality service for the transporting of voice package. The simulation to result shows that the voice over MPLS can provide more reliable and efficient carrying network than VoIP, the former can make the voice service meet the demand of service quality.
