Service function chain migration method and device, equipment and storage medium

The invention provides a service function chain migration method and device, equipment and a storage medium, and can be applied to the technical field of communication. The method comprises the following steps: receiving a plurality of target service requests in each target time slot, obtaining a plurality of target service function chains, deploying the plurality of target service function chains, and judging whether at least one service function chain which is abnormally deployed exists or not; and if yes, setting a preset indication variable as 1, and carrying out descending sort on a plurality of target paths corresponding to the service function chains with the abnormal deployment. Searching an original service function chain corresponding to the shortest target path and judging whether the original service function chain can be migrated or not, and if yes, further judging whether a predicted overhead value corresponding to the shortest target path is smaller than a preset overhead value or not; and if y
