Mobility-aware iterative sfc migration in a dynamic 5g edge environment

Abstract

One example method includes predicting a next expected position of the user in a communication network, determining that an SFC request by the user must be migrated from a current node in order to resolve a performance problem of services in the SFC, determining which VNFs of the SFC should be migrated to resolve the performance problem, determining a best migration plan for the VNFs for resolving the identified performance problem, and the best migration plan includes a migration path with a shortest migration delay, finding, in a service chain path identified in the best migration plan, one or more candidate target nodes for migration of the VNFs, and identifying a target node with adequate resources to support the VNFs, and migrating the VNFs from the current node to the target node with the adequate resources.
