Nine vendors participate in joint OIF/ONF Transport SDN interoperability demonstration
Announced Date: 9/17/2014 Published Date: 9/18/2014

As part of the Optical Internetworking Forum (OIF) and the Open Networking Foundation (ONF) Global Transport software defined networking (SDN) interoperability demonstration, it has been announced that nine vendors are participating in testing at a number of carrier labs worldwide.

Vendors participating in the testing are as follows: ADVA Optical Networking; Alcatel-Lucent; Ciena; Coriant; Fiberhome; Fujitsu; Huawei Technologies; NEC Corporation of America; and ZTE. Carriers China Mobile, China Telecom, TELUS and Verizon are hosting the testing in their labs.

The testing is due to be completed this month and provides real-world scenarios for both vendors and carriers to test prototype Transport SDN technology. OpenFlow extensions developed in the ONF optical transport working group are being prototyped and tested in the demonstration in both CDPI (control data plane interface) and CVNI (control virtual network interface) forms.

Vendors are also testing prototypes of controller northbound interfaces for service request and topology functions developed as an OIF activity. The framework of this demonstration is cloud-bursting, or application-based bandwidth-on-demand between data centre sites.

Testing based on this real-world use case illustrates the potential for deployment of Transport SDN technology, the common interfaces required, the need for interoperability and the operational challenges. Results of the testing will be released in October in a whitepaper and at the Layer123 SDN and OpenFlow World Congress.

The OIF and ONF first announced a partnership relating to Transport SDN at the end of June, noting they would collaborate throughout 2014 on a global Transport SDN demonstration to be conducted in several carrier-hosted labs.

Commenting on the interoperability demonstration, Vishnu Shukla of Verizon and president of the OIF said, "This joint work is an initial step in solving the practical issues of implementing transport SDN in commercial networks with the shared goal to make transport networks more programmable to enable a new era of dynamic services".
