SAN JOSE, Calif. — The Optical Internetworking Forum released a set of requirements for software-defined networks in carrier transport networks. The effort provides another proof point that SDN, a potentially disruptive new approach to networking, is gaining momentum among large network operators.
The document has been in the works since March at the OIF, which includes more than 100 members, many of them carriers. Hans-Martin Foisel, head of hybrid network technology in Deutsche Telekom's fixed mobile engineering Germany department and an OIF board member, said in a press release that the work forms a foundation for future specifications and agreements the group plans to draft as part of a broad SDN framework already in the works.
The OIF laid out requirements for an SDN orchestrator, a new and key networking element described in the document. It also described requirements for elements such as control, data, and management planes in an SDN network.
The work references OpenFlow 1.3.1, the most recent version of an emerging protocol for SDN.
The orchestrator is a new and key element in software-defined networks.
