Multi-domain resource processing method and system for software defined network

The application discloses a multi-domain resource processing method and system for a software defined network. The method comprises the following steps: sending a sensing request to a data layer in the software defined network; receiving multi-domain resource information fed back by the data layer after reception of the sensing request; processing the multi-domain resource information to obtain resource pool information of the software defined network; and storing the resource pool information in a multi-domain resource pool. According to the embodiment of the application, sensing of multi-domain resources in the software defined network is realized, and sensed multi-domain resource information is virtualized, so that management of the multi-domain resources in the software defined network is realized.
