摘　　要：本文主要对VSAT卫星通信链路备份技术进行研究,通过分析VSAT卫星通信系统现状以及路由优先级对选路的重要作用,并通过实验的方式验证基于地面链路的MPLS VPN网络,通達修改VPN路由的优先级以及VPN实倒内BGP路由的忧先级,实现卫星链路作为地面链路备份的通信技术。This paper focuses on the research of MPLS VPN technology in the ocean information communication network.Through the analysis of the current situation of the ocean information communication network,the architecture design of MPLS VPN technology in the network and the important role of RD value and RT value in the VPN instances,the matching strategies of import RT and export RT of different VPN instances are verified through experiments.
