基于MPLS VPN虚拟子网划分技术的电子政务平台

在MPLS VPN(Multi Protocol Label Switch,Virtual Private Network)网络中,当PE(Provider Edge Router)向边缘方向扩展时,需要维护更多的路由条目,大量浪费了开支和带宽利用率.为此采用MPIS VPN的PE分层体系结构HoPE(Hierarchy of PE)解决方案,给出了实际组网设计和具体参数的配置.结果表明,该设计成功搭建了安全可靠,能够承载数据、语音、视频等多媒体业务并能满足政府业务需求的多功能电子政务平台.其MPE(Middle-level PE)路由表条目缩小了90%,CPU利用率由38%降低到6%;UPE(Underlayer PE)设备路由表条目缩小了99%,CPU利用率由35%降低到5%;网络投资降低了89%.

E-Government Platform on MPLS VPN-Based Virtual Subnet-Partition Technique

In MPLS VPN(Multi Protocol Label Switch, Virtual Private Network),we need to safeguard more routes When PE(Provider Edge Router) expands to the edge,and this is a large amount of waste expenses and bandwidth utilization ratio. Because this,we have adopted HoPE (Hierarchy of PE).And making use of the data that is viable. With design and configure, the results show the advancement and the availability of the technology. It is safe and reliable, can bear the weight of the multimedia, such as data, pronunciation,video, etc. Have constructed the multi functional E-government platform which meets government's business demand.The routes of MPE(Middle-level PE ) is reduced 90%, CPU utilization ratio of MPE is reduced to 6% by 38% and the routes of UPE(Underlayer PE) is reduced 99%,CPU utilization ratio is reduced to 5% by 35%. Network investment is reduced 89%.
