| 通过对现有各专网方案所存在问题及未来数据网络演进趋势的分
析，以ATM-MPLS重叠网络的方式设计了一种新型VPN方案，并提出在现网的具体构建策略，
证明了该方案具有现实部署的可行性。通过OPNET实现语音、数据及视频等多业务的仿真模

| Abstract: |
| By analysing both the shortcomings of the existing private networks and the evol
ution trend of data networks, a new type of VPN(Virtual Private Network) solutio
n is designed. Then the construction strategies for existing networks are propos
ed, and the new VPN solution is proved to be feasible. Voice/data/video services
are simu
lated by OPNET, and under the condition of the heavy background traffic the res
ponse time of the new VPN solution is less than 0.6 s without congestion. This n
e
w VPN solution is considered to be a good solution for the evolution of broa
dband networks. |
