摘要:

移动互联网的高速发展导致了流量的快速膨胀和网络向分组方向的快速演进。同时,移动网络向LTE 的演进也要求对网络拓扑进行较大调整。传统的以MSTP 为主的回传网络难以适应移动网络发展的要求。如何建设新一代的回传网络以满足 3G/LTE 时代的移动网络回传要求,是本文探讨的重点。

关键词: IPRAN, MSTP, LTE, IP/MPLS, MPLS-TP, 回传

Abstract:

Rapidly developed mobile internet brings internet traffic fast grows and carrier network evolution to packet network.On the other hand,it needs great adjustment to nowadays topology while mobile network evolving towards LTE.Traditional backhaul based on MSTP cannot meet the requirements from mobile network development.It is studied that the backhaul network reconstruction in new era in this paper.And some key points are also discussed.

Key words: IP RAN, MSTP, LTE, IP/MPLS, MPLS-TP, backhaul
