The Open Infrastructure Foundation (OIF) announced the successful completion of its multi-vendor 2020 transport SDN Application Programming Interface (API) interoperability demonstration at Telefonica’s Madrid lab. To validate the benefits of transport SDN worldwide and transport network transformation for the 5G era, OIF members participated in a ten-week long interoperability testing exercise focusing on SDN-based programmability, control and automation.
OFI said members tested Layer 1 and Layer 0 OTN control using ONF T-API 2.1.3, with additional testing of OpenConfig device APIs for transport equipment in network-operator-defined use cases. Participating vendors included ADVA, Ciena, Cisco Systems, Infinera and Nokia. Network operator Telefonica hosted the demo, while China Telecom, Telia and TELUS participated as consulting network operators.
The participants described the completed demo as a milestone toward widespread SDN deployment in production networks. “By aligning vendors for a shared purpose – interoperability – and testing multiple use cases, we’re fostering manageability and flexibility in the network to allow deployment of cloud-based services, meet dynamic bandwidth demands and accelerate transport network transformation for the 5G era,” said Arturo Mayoral, Telefonica’s Lead of Optical SDN strategy.
