MPLS-VPN在跨场区航天数据网中的应用

Application of MPLS-VPN in Space Data Network of Cross-field

对分布在不同城市的跨场区航天数据网而言,依托航天骨干网构建各分站内部私有专用网络是迫切所需。将MPLS-VPN(多协议标签交换虚拟专用网),多层标签技术应用到航天数据网中,达到高速转发业务数据和增强其稳定性及安全性。介绍MPLS-VPN的原理及关键技术,结合跨场区航天数据网建设的现状提出一组MPLS-VPN航天数据网结构,分析使用MPLS-VPN实现组网的部署情况,并且实验仿真跨场区航天数据网的组网环境。用2种常用的用户业务数据为场景,通过测试网络的性能指标,验证了采用MPLS-VPN架构方案的优点。

For the space data network distributed in different cities,it is an urgent need to build a private network within each substation relying on the space backbone network.MPLS-VPN multilayer label technology is applied to the aerospace data network to achieve high-speed forwarding of business data and enhance its stability and security.This paper mainly introduces the principles and key technologies of MPLS-VPN,proposes a set of MPLS-VPN aerospace data network structure combined with the current situation of cross-field aerospace data network construction,analyzes the deployment of using MPLS-VPN to achieve networking,and simulates the networking environment of cross-field aerospace data network through experiments.Using two kinds of common user service data as the scene,through the test of network performance indicators,the advantages of MPLS-VPN architecture are verified.
