【摘要】:針對傳統(tǒng)MPLS-VPN組網(wǎng)架構(gòu)存在的擴展性不足、安全性不高與傳輸質(zhì)量差等問題,提出一種使用層次化運營商邊緣設(shè)備技術(shù)優(yōu)化網(wǎng)絡架構(gòu)的方法。采用設(shè)備層級化的方式對網(wǎng)絡拓撲結(jié)構(gòu)進行優(yōu)化改造,使設(shè)備的路由控制和數(shù)據(jù)轉(zhuǎn)發(fā)實現(xiàn)最大限度的分離,引入鏈路利用率權(quán)值對等價多路徑選擇算法進行優(yōu)化,并把優(yōu)化前后網(wǎng)絡的各項性能指標進行對比。實驗結(jié)果表明,優(yōu)化后流量的負載更均衡,數(shù)據(jù)包的延時、抖動、丟包率明顯下降,網(wǎng)絡的擴展性、安全性以及傳輸質(zhì)量明顯提高。
[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.
