Huawei said it will display its 5G-oriented mobile bearer solution X-Haul at Ultra-Broadband Forum (UBBF) 2017 in Hangzhou, China from October 18 to October 19, 2017.
Telecom operators need 5G bearer networks – which are capable of supporting service deployment and agile operation — to penetrate emerging service markets such as smart manufacturing and the Internet of Vehicles (IoV).
Mobile service providers face planning and design related challenges when they for the 3G / 4G / 5G multi-service bearer and network scale expansion. The solution for telecom operator is to construct bearer networks efficiently, reducing the TCO.
Huawei X-Haul solutions ensure fronthaul and backhaul coverage, implementing flexible access in all scenarios. Flexible networking is implemented through the IP, microwave, and OTN access technologies, enabling unified fronthaul and backhaul bearing whether or not optical cables are used.
For backhaul scenarios in areas that have a high population density, Huawei launched 50GE/100GE adaptive network slicing router, which provides seamless 100GE compatibility even when providing 50GE base station access.
Huawei launched 5G-ready microwave solution for scenarios where optical cables are not used.
Telecoms can ensure capacity upgrade through the use of a same frequency band or inter-frequency band Carrier Aggregation (CA) technology, which enables any-media 10GE to site. Huawei launched 100G Full-outdoor WDM device that can be deployed at the same site as the base station to save optical cable resources.
Huawei said the cloud-based architecture of X-Haul enables agile operations on 5G bearer networks. The device plane introduces Segment Routing, EVPN and OSP-TE protocols, simplifying bearer device control plane protocols and unifying the service model to implement the automated management life cycle of the bearer network.
Huawei X-Haul uses the Flexible Ethernet (FlexE) technology to implement network slicing and help operators accelerate new service innovation. FlexE can divide a single physical Ethernet port into multiple Ethernet flexible hard pipes based on timeslot scheduling, implementing service statistical multiplexing in the same slice while without services affecting each other in different slices.
Telecoms can achieve end-to-end coordination between FlexE-based network slices and wireless and core networks through the Network Cloud Engine.
X-Haul introduces the cost-effective 50GE technology at the access layer, which reduces Capex by 30 percent, while enabling smooth future upgrade to 100GE based on FlexE.
The IP layer supports 200GE/400GE interfaces at the aggregation and core layers, which use the IP + optical two-layer architecture.
The optical layer implements one-hop transmission of wavelengths. Telecoms can expand single-wavelength bandwidth on demand to 200G/400G. This enables 4G-to-5G bearer network evolution, which will maximize operator investment.
“The Huawei X-Haul solution fully supports 4G/5G bearing, so as to effectively support operators’ new service development and expand the business blueprint,” said Jeffrey Gao, president of Huawei Router & Carrier Ethernet Product Line.
Huawei has deployed over 190 mobile bearer networks in more than 100 countries, which bear more than 2.8 million base stations, serving 1/3 of the world’s users.
