Maintaining and developing a national software-defined network based on OpenFlow switches and controllers to prototype ideas and enable network research.
What is software-defined networking?
Software-defined networking involves the de-coupling of switch/router hardware from the control and management software that traditionally comes with it. In a SDN, separate controller devices control and manage the switch/router hardware using a pre-defined protocol.
This approach allows the development of feature-rich control and management software without having to worry about the specifics of each hardware platform, thus enabling true vendor-independent network operations and management.
Project aims and benefits
The most comprehensive and mature protocol standard in the SDN arena is OpenFlow
A national SDN using OpenFlow would enable network virtualisation, allowing networking researchers to experiment with new communications protocols and architectures, stimulating new innovative approaches to Internet services.
In addition, an OpenFlow enabled network would create a platform for Janet to experiment with new ways of engineering and delivering advanced networking services to support data-intensive research projects such as the Large Hadron Collider, radio astronomy, biosciences and climate modelling.
