Huawei intros SDN-based mobile backhaul solution

BANGALORE, INDIA: Networking company Huawei has released LTEHaul, software defined networking (SDN) based mobile backhaul solution, at the Mobile World Congress 2013.

The solution helps operators resolve network issues during the evolution to LTE networks. There are three large gaps that exist in backhaul networks that operators must leap over during the evolution to LTE and LTE-A networks. First, a large gap exists between LTE hotspots and limited hotspot backhaul sites.

The LTEHaul solution extends the traditional backhaul network downwards to form a fronthaul, facilitating the management and maintenance of massive hotspot backhaul nodes. The second gap is present between the increase in LTE bandwidth and the limited bandwidth on the traditional backhaul network. Third, there is a large gap between traditional backhaul and core networks, says a release.

The LTEHaul solution stretches the traditional backhaul network upwards to achieve end-to-end fast service provisioning, protection switching, and fault locating from eNodeBs to evolved packet cores (EPCs).

By addressing the large bandwidth and seamless quality service requirements of new LTE/LTE-A-oriented technologies such as eMBMS, COMP, and eICIC, the Huawei LTEHaul solution provides users with site-free and virtual service access, the release adds.

Meanwhile, the fronthaul, backhaul, and core are unified in the network structure, thereby overcoming the bottleneck of traditional GSM/UMTS network structure and bandwidth.
