Huawei has announced completion of the industry's first multi-vendor Wireless Transport SDN Proof of Concept (PoC) with the Open Networking Foundation (ONF), a non-profit organization dedicated to accelerating adoption of open Software-Defined Networking (SDN). The PoC, held from October 7th to 9th in Madrid, was hosted by Telefonica and IMDEA Networks Institute. Another four wireless transport vendors and one router vendor also joined in the PoC.
The goal of the PoC was to encourage the development, testing, and implementation of open SDN for wireless transport as well as demonstrate multi-layer optimization on an open SDN infrastructure by using the Open Networking Operating System (ONOS) open source SDN controller.
Two demonstration cases were tested, which included capacity-driven air interface and flow-based shaping. The capacity-driven use case demonstrates a network's ability to adapt to traffic demand and to efficiently optimize wireless resources for a more energy efficient operation of the transport network. The flow-based shaping use case demonstrates the network's ability to adapt and respond to changing conditions such as the weather impacting wireless transport networks.
Huawei used SDN based RTN900 microwave equipment with OpenFlow interface for the PoC. This first appearance of SDN based RTN900 not only shows Huawei's ability to innovate, but also highlights the company's strategy of promoting new technologies to industry. For Huawei, the PoC shows the company's commitment to development with SDN technology, seeking to add value for customers and promote SDN industrial development with ONF.
