Enabling service market in metro and access networks – the ADDONAS project

SDN/OpenFlow solutions have shown their strengths in datacenter, cloud and experimental environments. Currently there is a number of activities employing SDN concepts to other use cases. The ADDONAS project (Active Distributed & Dynamic Optical Network Access Systems) proposed to use SDN concept to support access to the services for the users and fair access to the resources for service providers. This paper presents the work done in the ADDONAS project, discusses architecture and describes development related to deployment of the SDN system to enable flexible service provisioning in combined metro and access architectures. © 2013 IEEE
