| 摘 要： | 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拟,其中以数据业务响应时间作为量化指标,仿真结果表明该新型网络在高负载下响应时间在0.6s以内,且不累积拥塞,具有类似ATM的技术优势,为宽带网络演进提供了一种解决思路.

| Abstract: | By analysing both the shortcomings of the existing private networks and the evolution trend of data networks, a new type of VPN(Virtual Private Network) solution is designed. Then the construction strategies for existing networks are proposed, and the new VPN solution is proved to be feasible. Voice/data/video services are simulated by OPNET, and under the condition of the heavy background traffic the response time of the new VPN solution is less than 0.6 s without congestion. This new VPN solution is considered to be a good solution for the evolution of broadband networks. |
