System, method, and computer program for managing hierarchy and optimization in a network function virtualization (NFV) based communication network

摘要

A system, method, and computer program product are provided for managing hierarchy and optimization in network function virtualization based networks. In use, a first hardware unit of a plurality of hardware units associated with a network function virtualization (NFV) based communication network is identified, the first hardware unit being identified based on a first load characteristic associated with the first hardware unit. Further, a first virtual network function (VNF) instance associated with the first hardware unit is identified, the first VNF instance being associated with usage of at least one service. Additionally, at least one traffic route associated with the first VNF instance is identified, the at least one traffic route being associated with usage of the at least one service. Furthermore, a second hardware unit for handling at least a portion of a workload associated with the at least one service is identified, the second hardware unit being identified based on a second load characteristic associated with the second hardware unit, and the second hardware unit being capable of utilizing the at least one traffic route. Still yet, a second VNF instance is initiated in the second hardware unit. Moreover, at least part of the at least one service is migrated from the first VNF instance to the second VNF instance without disrupting the service.
