The need for generic control functions and a controlorchestration protocol The NBI of the SDN/OpenFlow or GMPLS/ PCE Controllers are typicallytechnology and vendor dependent. The multi-domain SDN orchestrator shall implement different plugins for each of thespecific controller’s NBI. The STRAUSS project defines a generic functional model of a control plane for theprovisioning of connectivity, topology dissemination and path computation, anddefines an associated protocol (the Control Orchestration Protocol - COP-) The COP would be able to be used as the East-West IF of different orchestrators.Multi-domain SDN orchestrationControl OrchestrationProtocol (COP)SDN ControllerOF 1.3OF 1.3GMPLS/PCEControllerOF 1.3MAN(Packet TransportNetwork)SDN ControllerOF 1.0WAN(e.g. WDM/Flexi-grid)EUCNC15 – OPN02.2OF 1.0OF 1.0MAN(Packet Transport Network)
