It should be understood that the example of communication path of embodiment of the present invention request is only an example, the embodiment of the present invention is not limited thereto.

403, SDN controllers determine forward-path.

After SDN controller receives communication path request, this end node can be determined according to the forward-path algorithm of its own Forward-path between peer node.A kind of possible computation algorithm is as follows:

SDN controller safeguards the topology and available bandwidth resources data of entire data center's IP network, and according to history stream Measure the statistical collection QoS data of each forward-path.Lead to when SDN controller receives the needs that VM control managing device is sent and creates Believe that bandwidth demand and QoS needed for this end node and peer node MAC Address in path, this end node and peer node communicate need After asking, the forward-path for meeting condition can be selected, and modify originally from the bandwidth resources of maintenance and QoS data library Available bandwidth resources data.

404, SDN controllers send forwarding flow table to forwarding surface equipment, carry forward-path information.
