Cloud orchestration with SDN/OpenFlow in carrier transport networks
Achim Autenrieth, Jörg-Peter Elbers, Paweł Kaczmarek, Paweł Kostecki · 2013
Software Defined Networking offers network programmability through open Application Programming Interfaces (API) and OpenFlow is the most prominent SDN protocol today. However, it is still quite immature and some concepts and features are missing for application in carrier transport networks. In this paper the authors will give an overview of current activities and latest results of the OFELIA project for OpenFlow enabled lambda switching in ROADM-based optical networks. Then the authors highlight required functionality and propose a system architecture to offer cloud orchestration services over multi-carrier and multi-technology transport networks.
