System and computer for controlling a switch to provide a virtual customer premises equipment service in a network function virtualization environment based on a predetermined condition being satisfied

Abstract:

A system for providing virtual customer premises equipment (vCPE) services to a customer by using network function virtualization (NFV) clouds located in different regions, comprises an orchestrator managing NFV clouds located in at least two different regions; and a service manager located in each of the NFV clouds, the service manager interworking with the orchestrator. Also, the orchestrator controls the service manager to move a vCPE service for the customer from a first NFV cloud to a second NFV cloud among the NFV clouds, and provides the vCPE service to the customer through the second NFV cloud.
