HUAWEI TECHNOLOGIES CO., LTD.

Huawei Confidential

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) 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.

BFD can be performed within milliseconds; ARP detection can be performed within seconds © 2009 HUAWEI TECHNOLOGIES CO., LTD. All Rights Reserved.

Network Design --Iub network topology

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 .
