Problems solved by technology
[0004] However, in the process of restoring the interface and establishing the associated network protocol, after a network protocol is established, the service traffic corresponding to the network protocol will be switched to the network device. If the network protocol is not completed, the service interface cannot receive and send subsequent data packets under the incomplete processing of the network protocol, resulting in the inability of the network device to perform corresponding service processing, resulting in service interruption for a certain period of time

Embodiments of the present invention provide a service recovery method, device and electronic equipment. Wherein, the method includes: after restarting, acquiring the protocol delays of the plurality of service interfaces, the protocol delays being used to indicate the time required to establish a protocol associated with the service interface when the service interface is in the up state; The plurality of service interfaces are restored sequentially in descending order of the protocol delays; whenever a service interface is restored, a protocol associated with the service interface is established through the service interface. According to the protocol delay, the recovery sequence of each service interface can be reasonably set, so that the protocols associated with each interface are close to being established at the same time, effectively shortening the duration of service interruption caused by the restart of the device to restore the service.
Description
technical field [0001] The invention relates to the technical field of network communication, in particular to a service recovery method, device and electronic equipment. Background technique [0002] In some application scenarios, network devices need to be restarted due to actual needs, such as upgrading the system version. After restarting, each service interface in the network device is in the down (closed) state, and needs to be restored to the up (open) state again, and the network protocol associated with the service interface is established through each service interface to perform corresponding service processing. [0003] In order to shorten the duration of service interruption caused by the restart of the network device, in related technologies, before the restart of the network device, the business traffic loaded by the network device can be switched to other network devices, and after the restart of the network device, the business traffic can be re-distributed....
