A dynamic recovery method and device for services, and a software defined network (SDN) controller. The method is applied to a software defined network (SDN) controller, and comprises: obtaining an instruction of a service interruption in a transmission network, to determine a service list of services affected by the service interruption; and conducting service path recovery calculation on the services in the service list using a plurality of pre-constructed service recovery threads according to a plurality of items of pre-constructed first service data required for service recovery, to complete service path recovery of each service. By means of the technical solution, the dynamic recovery for services has high efficiency, thereby guaranteeing that the service recovery time is within a required range, and achieving the purpose of quick recovery. |
