Huawei Brings SDN to the Application and Control Layers of the Network

By Laura Stotler March 23, 2016

Huawei is making great strides in the software-defined networking space (SDN), announcing offerings geared toward the application and control layers of the network. The company is putting emphasis on its Transport-SDN applications (T-SDN), which bring virtualization efficiencies and flexibility to targeted areas of the network.

At the application layer, Huawei is offering a bandwidth on demand solution that works for both enterprise leased lines and Data Center Interconnects (DCI). The company has also launched its Transport Innovation Platform (TIP), which is built on a T-SDN controller. The platform converges ICT programming capabilities by incorporating bottom-layer interfaces and basic programming with a transport service engine.

The application layer offerings are meant to help operators and third parties roll out programming and new services easily, while facilitating agile design and customization. TIP also enables the import of third-party components and service templates, which encourages joint innovation and an open transport network ecosystem.

The Huawei T-SDN solution is using an ONOS-based super controller at the control layer, offering standard and open T-APIs for managing SDN domain controllers from a variety of vendors. The offering facilitates coordination among disparate vendor transport networks while also offering unified modeling at the network layer. This is achieved using end-to-end route computation across multi-vendor devices, which accelerates service provisioning while reducing the time to market for new services and solutions.

Telefonica and Sedona Systems have already worked with Huawei on interoperability, demonstrating multi-vendor and multi-domain interconnectivity. Huawei’s T-SDN controller offers open APIs for integration with both companies’ devices, and Huawei is also providing IP controllers and devices for Telefonica’s multi-vendor interconnectivity within a fixed network transport domain.
