MPLS VPN组网仿真与应用设计

为了解决传统"专线"组网的缺点,改善传统IP网络、帧中继和ATM网络的缺陷,在详细分析了MPLS VPN应用现状以及特点的基础上提出一种基于MPLS的VPN组网方案.采用OPNET网络仿真软件对组网场景进行建模仿真.得出MPLS VPN具有较高吞吐量、较小时延和丢包率的结果,并结合实例和仿真结论分析了应用MPLS VPN组网所显现出的优势.在此基础上得到有价值的结论,即将MPLSVPN大胆应用于跨越不同地理区域的公司、企业和军事通信组网中必将带来广阔的应用前景.

Application and Simulation of MPLS VPN Networking

In order to overcome the shortcomings of traditional "special telephone line" networking,and improve the performance of IP network,frame relay and ATM network,a VPN networking scheme based on MPLS was put forward after analyzing the current application and features of MPLS VPN.Some simulation scenes were introduced by using OPNET.And the result obtained showed that MPLS VPN has high throughput,short time delay and small packet loss rate.The advantages of using MPLS VPN networking was analyzed based on pract...
