OIF's 2020 Transport SDN API Interoperability Demo

OIF completed a multi-vendor 2020 Transport SDN Application Programming Interface (API) interoperability demonstration aimed at validating the benefits of transport SDN for the 5G era.

The ten-week long interoperability testing exercise, which was held in Telefonica’s Madrid lab, focused on SDN-based programmability, control and automation — testing 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. China Telecom, Telia and TELUS participated as consulting network operators.

“Operators have demanded more open optical networks to enable flexibility, lower costs, and best-of-breed options,” said Scott Wilkinson, Lead Analyst at Cignal AI. “Standard management interfaces and multi-vendor interoperability are critical to open optical networks. The interoperability demonstration recently performed under the guidance of the OIF is a major step towards achieving those operator goals.”

“The successful completion of the OIF 2020 Transport SDN API interoperability demonstration is a significant milestone toward widespread SDN deployment in production networks,” said Arturo Mayoral, Telefónica Transport Global CTIO Unit – Technology Expert and Lead of Optical SDN strategy. “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.”

The results of the multi-vendor demonstration will be revealed during a public read-out webinar event being held in partnership with Lightwave, Tuesday 12 January 2021, 6:00-7:30am PST. Register for free here

A private read-out event for demo participants and invited Network Operators is scheduled for Tuesday 19 January 2021.

OIF representatives will give presentations on the current status of the 2020 OIF Transport SDN API Interoperability Demonstration during the below events:

• NGON & DCI World Digital Symposium – Friday 04 December 2020 – 20:00-20:15pm CET, OIF Speaker: Arturo Mayoral López de Lerma, Telefonica S.A
• ECOC – Monday 07 December 2020 – 17:20-17:40pm CET, OIF Speaker: Arturo Mayoral López de Lerma, Telefonica S.A

OIF validates Transport Application Programming Interface (T-API) 2.0

The Optical Internetworking Forum's Transport Application Programming Interface (T-API) 2.0 is market ready, following a six week, multi-vendor interoperability demonstration. The results of the interoperability test are reported in a new whitepaper published by the OIF.

The multi-vendor demo led by four network operator labs included lab-deployed and cloud-deployed systems testing new dynamic behavior use cases and deployment scenarios. The demo also incorporated service provisioning scenarios at the LSO Presto reference point in the MEF LSO architecture, using the MEF NRP Interface Profile Specification (MEF 60), which defines extensions to T-API in support of Carrier Ethernet services.

Participating network operators were CenturyLink, China Telecom, SK Telecom and Telefónica and vendors included ADVA, Coriant, Infinera, NEC/Netcracker, Nokia and SM Optics. Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) was a participating academic institution and TELUS Communications participated as a consulting network operator.

Key findings detailed in the whitepaper:

• Open Networking Foundation (ONF) T-API 2.0 specifications have addressed the main issues identified in the OIF’s 2016 testing and provide a basis for real-time orchestration of on-demand connectivity setup, control and monitoring across diverse multi-layer, multi-vendor, multi-domain carrier networks
• Additional scaling and performance enhancements will need to be addressed as T-API is deployed in real networks, such as refinements to the model, greater detail in error codes to improve debugging properties, and potential implementation options such as a separate server for notifications of network events
• The API allows for some variability in the use of topology abstraction depending on business requirements and technology; documentation of supplementary examples for topology abstraction will help application and orchestration software developers.

“Standardized and open SDN APIs reduce complexity in intra and inter-domain operations, allowing us to provide more diverse services to our customers in less time,” said Park Jin-hyo, EVP of ICT R&D Center at SK Telecom. “After successfully completing the test trial, SK Telecom will keep engaging in 5G transport network and service development by opening APIs and transforming the current infrastructure into Network-as-a-Service (NaaS) Platform.”

Layer 1 Transport API interoperability demo -- MEF, ONF, and OIF

Wednesday, July 25, 2018  MEF, Video  

The recently concluded MEF-ONF-OIF interoperability demo that focused on the Software-Defined Networking (SDN) Transport Application Programming Interface (T-API).

NEC's Karthik Sethuraman and Centurylink's Jack Pugaczewski provide an overview of the demo. A proof-of-concept (PoC) on this topic will be presented at #MEF18.
