Bandwidth on Demand services are already a reality in most NRENs, including Géant, where AutoBAHN allows end-user to request multi-domain services with a guaranteed bandwidth during a period of time. AutoBAHN provides the BoD service across multiple domains through the NSI CS v2 protocol and it currently does not support SDN domains. However, since the NSI CS multi-domain protocol aims to be technology agnostic, the Géant 4 SDN-based BoD use case proposes to use is developing the DynPaC framework (developed during Géant 3plus) as an application within ONOS, to serve as the Domain Manager for SDN domains, as depicted in Figure 1.
