Product:NEC Unified Network Coordinator
Discussions of SDN architecture generally refer to the controller as a single entity, but real-world deployments will likely mean the presence of multiple controllers. NEC's Unified Network Coordinator, acts as a kind of controller of controllers. UNC can configure multiple NEC ProgrammableFlow controllers at the same time, including controllers within the same data center and in separate data centers, and instantiate policies across multiple domains. The UNC can redirect traffic if a controller becomes unreachable, and the UNC itself can run an active/standby cluster.
