Huawei IPRAN Migration

Solution Overview

2009 HUAWEI TECHNOLOGIES CO., LTD. All Rights Reserved.

Challenge for MBB service burst

1. Network evolution from traditional network to IP network

2. High investment by:

Hardware of Radio, Transmission network ,etc..

High throughput service lead huge transmission rent fee and capacity limitation

3. How to guarantee the Qos of IP network

Fast trouble shooting

Qos guarantee by different user and service

Network safety solution (Iub/Abis over IP:2BFD+1ARP)

BFD can be performed within milliseconds; ARP detection can be performed within

seconds

Solution:

2 BFD session + 1 ARP session.

BFD session on Master port to physical IP.

ARP session on backup port to virtual IP of VRRP.


Network Design --Iub network topology

Page 23

Iub over IP is layer 3.

Two GOUa boards and port work as active/standby mode.

Two PE/Routers enable VRRP.

Between GOU and router work as 2 BFD + 1 ARP .
