Network resource processing method and device, gateway, controller and storage medium

The embodiment of the invention provides a network resource processing method and device, a gateway, a controller and a storage medium. Through the application network resources are stored locally. Only the currently occupied network resources need to be additionally stored in a preset resource list, and the corresponding relationship between the network resources and an occupation identifier forjudging whether the network resources are occupied by the network server or not does not need to be created for each network server which currently establishes the communication connection, so that the storage space of the gateway can be saved. The gateway selects a first network resource from the at least one network resource. Whether a first network resource is occupied currently needs to be judged. Whether the first network resource exists or not can be searched in the preset resource list, and only part of network resources in the first preset resource set are generally stored in the preset resource list.
