MPLS DiffServ在舰内VoIP QoS中的仿真与研究

Simulation and Research of MPLS DiffServ Module in the VoIP QoS inside the Ship

舰艇内部以IP承载语音VoIP作为话音通信手段,由于IP网络的固有劣势,使得VoIP服务质量得不到保障。为了改善VoIP的服务质量,对MPLS技术和QoS机制进行了理论分析,研究了MPLS DiffServ的工作原理,并通过OPNET仿真进一步验证其QoS保障能力,这对MPLS DiffServ在舰内通信系统的使用有着一定的促进作用。

VoIP（Voice over IP）is treated as a means of voice communication inner vessel.Due to the inherent disadvantages of IP network,the QoS of VoIP can not be guaranteed.In order to improve the VoIP QoS,the paper introduces the theory of MPLS technology and QoS mechanism,studies the working principle of MPLS DiffServ,and verifies its QoS guarantee ability through the OPNET simulation.The study promotes the use of the MPLS DiffServ theory in the communication system inside the ship.
