PALO ALTO – The Open Networking Foundation (ONF), a non-profit organization dedicated to accelerating the adoption of open software-sefined networking (SDN), today announced the availability of “Migration Use Cases and Methods.” Produced by the ONF Migration Working Group, the document provides recommendations for organizations looking to migrate to software-defined networks based on the OpenFlow standard.

The first deliverable of the Migration Working Group, this living document summarizes best practices and lessons learned from real-world open SDN migration use cases and deployments from different network domains. Referenced examples include Google’s inter-data center WAN use case, NTT’s provider edge use case, and Stanford’s campus network use case. The “Migration Use Cases and Methods” document describes a framework for migration methods exemplified by a set of target networks and offers a variety of requirements to ensure a complete and successful migration to SDN.

“SDN is making a dramatic impact on the networking industry, and many business and technology decision makers, including CTOs and those who own and operate networks, are seeking recommendations and best practices for SDN migration,” said Justin Dustzadeh, chief technology officer and vice president of technology strategy at Huawei, and chair of the Open Networking Foundation Migration Working Group. “The Migration Working Group’s ‘Migration Use Cases and Methods’ document is a valuable resource that can help network operators gain insights into real-world SDN migration use cases and learn more about the process of migrating services to an OpenFlow-based, software-defined network.” The ONF Migration Working Group was chartered in April 2013 to produce methods, guidelines, systems, and tools to migrate network services from a traditional network to an OpenFlow-based, software-defined network. The Working Group brings together practitioners who have carried out, or are interested in carrying out software-defined network migrations in order to reduce associated risks.
