Federating SDN-enabled islands with an extended NSI Framework

Software Defined Networking (SDN) is an emerging architecture for computer networking. SDN separates the control plane from the data plane in switches and routers. This paper describes a novel framework capable of provisioning end-to-end network services between resources attached to SDN clouds (e.g. data centres) controlled by OpenFlow or similar protocol. This paper proposes extensions in the form of a new NSI service, which will integrate SDN and NSI-CS messaging and functionality, delivering adequate mechanism for dynamic management of remote slices and corresponding interconnectivity between data centres. The framework extends the existing NSI model with a new service enabling the multi-domain service provisioning for SDN networks, in consequence providing a real end-to-end network service spanning multiple administrative domains. The extensions defined within the framework will be proposed for further standardization through the OGF standardization procedure.
