Description
Technical Field

Background
Software-defined networking (Software-defined Networking, SDN) technology is a network management method that supports dynamically programmable network configuration, improves network performance and management efficiency, and enables network services to provide flexible customization capabilities like cloud computing. SDN decouples the forwarding plane and the control plane of the network equipment, and the controller is responsible for the management of the network equipment, the arrangement of network service and the scheduling of service flow, and has the advantages of low cost, centralized management, flexible scheduling and the like.
Currently, the transport network of an SDN is capable of supporting rerouting, where rerouting includes dynamic rerouting and pre-made rerouting. When the fault occurs, the controller or the control plane recalculates a recovery route according to the current topology resource, and switches the service to the recovery route. The pre-fabricated rerouting means that a restoration route is calculated in advance when a service is created, and the restoration route is pre-configured at a service head node when the service is created; when a failure occurs, the head node automatically creates a connection based on the pre-made restoration route and switches the traffic to the restoration route.
However, both of the above methods have drawbacks, and the dynamic rerouting tends to have a long recovery time due to the real-time calculation of the recovery path. The restoration path for the pre-cast reroute is calculated already at the time of service creation, but may fail in restoration due to resources being occupied when a failure occurs.

In the embodiment of the application, in order to solve the problems that in the prior art, dynamic rerouting is adopted for path recovery, the time is long, the path recovery adopting the prefabricated rerouting has recovery failure caused by occupied resources, and the recovery time is long because the controller can not reduce the recovery time when network connection is interrupted and can ensure the effect of the success rate of the path recovery when the network is in fault.
As shown in fig. 2, one embodiment of the present application provides a network connection recovery method, which is performed by a network node, and includes:

When the network connection is interrupted during the execution of the target service, the network node (source node for executing the target service) selects a target path for recovering the network connection of the service from among the at least two transmission paths. Specifically, according to the priority selection sequence of the alternative paths in at least two transmission paths, whether the resources of each alternative path are available or not is judged in sequence; and determining that the alternative path with the priority order arranged at the forefront and available resources is the target path in at least two alternative paths.

s330, establishing connection by adopting an N-th alternative path through a resource reservation protocol, and switching the target service to the target path;
s340, judging whether other selectable alternative paths exist, executing step S350 when the judging result is yes, and executing step S360 when the judging result is no;
