【摘要】：针对传统MPLS-VPN组网架构存在的扩展性不足、安全性不高与传输质量差等问题,提出一种使用层次化运营商边缘设备技术优化网络架构的方法。采用设备层级化的方式对网络拓扑结构进行优化改造,使设备的路由控制和数据转发实现最大限度的分离,引入链路利用率权值对等价多路径选择算法进行优化,并把优化前后网络的各项性能指标进行对比。实验结果表明,优化后流量的负载更均衡,数据包的延时、抖动、丢包率明显下降,网络的扩展性、安全性以及传输质量明显提高。
[Abstract]:In order to solve the problems of insufficient expansibility, low security and poor transmission quality in the traditional MPLS-VPN networking architecture, a method of optimizing the network architecture by using hierarchical operator edge equipment technology is proposed. The network topology is optimized by means of equipment stratification, so that the routing control and data forwarding of the equipment can be separated to the maximum extent, the link utilization weight is introduced to optimize the equivalent multi-path selection algorithm, and the performance indexes of the network before and after optimization are compared. The experimental results show that the load of the optimized traffic is more balanced, the delay, jitter and packet loss rate of the packet are obviously decreased, and the expansibility, security and transmission quality of the network are improved obviously.
