The Optical Internetworking Forum (OIF) recently announced its intention to stage a global Software-Defined Networking (SDN) Transport Application Programming Interface (T-API) demonstration this fall. ONF will partner with the Open Networking Foundation (ONF) on the SDN transport API demo, which will promote SDN interoperability testing in carrier labs worldwide.
The goal is to spur development and adoption of open SDN technology standards considered essential to widespread commercial adoption of both SDN and network functions virtualization (NFV) technology. Facilitating NFV deployment and enabling carriers to more efficiently and effectively manage peak network traffic demand, link failures and network slicing are the driving motivators, OIF highlights in a news release.
SDN Transport API
Currently, the notification interface of the network transport layer is one primary focal point of the OIF global demo. As its moniker indicates, the notification interface notifies applications when congestion is observed and triggers rerouting and adding of capacity.
The network transport layer does not take account of events at the traffic layer above it. As a result, operators need to intervene manually when issues present themselves, OIF elaborates. The SDN T-API demo aims to resolve this glitch automatically.
Host carriers Verizon, China Telecom, China Unicom, SK Telecom and Telefónica will participate in the OIF SDN T-API demo. ADVA Optical Networking, Ciena, Coriant, Fiberhome, Huawei Technologies, Juniper Networks, NEC, Sedona Systems, SM Optics and ZTE will be participating vendors. Academic and research institutions, including China Academy of Telecommunication Research and Centre Tecnològic and Telecomunicacions de Catalunya will participate as well.
Network traffic is expected to continue soaring as new high-bandwidth applications, such as augmented and virtual reality (AR/VR), 4K video and networked IoT devices, are introduced. Among top-tier U.S. carriers, AT&T recently announced it is joining Intel’s ¨Super 7,”a group of leading Web and cloud companies that aim to make extensive use of SDN and NFV in their bids to dramatically improve network performance, capacity and data center design.
