摘要
A data center interconnection (DCI) network may comprise a data center controller (DCC) managing a plurality of data centers (DCs) interconnected by a provider network managed by a network provider controller (NPC). The provider network may be an OpenFlow based software defined networking (SDN) transport network. The DCC may initiate a virtual network service (VNS) negotiation with the NPC to connect the DCs and may specify a network abstraction granularity level. The NPC may respond by computing paths through the provider network accordingly and providing the DCC with one or more virtual networks (VNs). The DCC may compute virtual paths through the VNs and send virtual network element (VNE) connection setup commands to the DCC. The DCC may convert the VNE connection setup commands into network element (NE) commands to setup connections in NEs of the provider network. The DCC and the NPC may perform fault monitoring, detection, and recovery.
