Huawei Huawei IP RAN (Based (Based on on IP/MP IP/MPLS LS )solution )solution has has an ability ability for for easy expans expansion ion with automatically IP routing protocol, when new new ATN (access (access router) added in the network, just need few modification on the ATN box like IP address etc. Using Huawei Huawei NMS U2000 U2000 GUI to configu configure re the IP IP Backhaul Backhaul ATN router routerss in batch batch remot remotely ely..

With Huawei NMS U2000 GUI based based on rich IP/MPLS IP/MPLS features, features, management is centralized ,troubleshooting ,troubleshooting is highly efficient with integrated expert analysis system and demarcation function is so easy for maintain team to distinguish responsibility for poor quality issue in different segment network. Huawei router has built-in IPFPM/Y.1731/MPLS-TP OAM/BFD features, which can measure the network KPI anytime and fast locate failure point within few minutes. With the function of DCN (Data communication Network) communicating communicating by the ATN itself after power on, we can remotely remotely configure big amount amount ATN routers routers in batch with NMS, no need any configuration on site, fast implementation.

Comparison between IP RAN(IP/MPLS) and PTN Solution (2) Item

PTN

IP RAN (IP/MPLS)

Comments • X2 traffic needs end to end delay less than 10ms.

LTE ready

Open architecture

PTN use MPLS-TP protocol: X2 traffic will go through aggregation nodes, which bring more delay. IP RAN(based on IP/MPLS): The gate way of eNB is ATN, X2 traffic can be forwarded as near as possible, lower delay and at lest 5% bandwidth resource can be saved. • eNodeB Re-homing frequently when expansion happen, IP RAN solution need not manually configure. • e-MBMS service needs IP multicast to realize P2MP between e-MBMS gateway and eNBs. PTN can’t support this feature. The interoperability of MPLS-TP (PTN use) equipment is so limited. MPLS-TP network is a closed network. Huawei router (Based on IP/MPLS) interoperability has been proven by famous 3rd party organizations and many Tier One operators.
