The Open Networking Foundation (ONF), a non-profit organization dedicated to accelerating the adoption of open Software-Defined Networking (SDN), today announced that the ONF OpenFlow Conformance Testing Program has welcomed six testing labs and established the ONF Testing Leadership Council (TLC) since its inception one year ago. In addition to its four previously announced testing labs, the China Telecommunication Technology Labs (CTTL), hosted by the China Academy of Telecommunication Research (CATR) of the Ministry of Industry and Information Technology (MIIT) in Beijing, and the Network Benchmarking Lab (NBL), co-hosted by the National Chiao Tung University (NCTU) in Taiwan, are now ONF-accredited labs for testing conformance to the OpenFlow specification.
