  • Method for providing virtual CPE service by using single internet line and network function virtualization cloud
    Patent number: 10778467
    Abstract: An NFV cloud for providing a vCPE service by using a single Internet line may comprise: a vCPE service having a virtual LAN interface, a virtual WAN interface, and a virtual management interface; a virtual LAN network, a virtual WAN network, and a virtual management network connected to the virtual LAN interface, the virtual WAN interface, and the virtual management interface, respectively; a physical LAN interface for providing customer traffic to the virtual LAN network; a physical WAN interface for connecting the virtual management network to the outside in order to output, to the outside, traffic which has been output from the virtual WAN network and passed through the vCPE service, or to provide a management function for the vCPE service or the NFV cloud; and an interface agent for controlling a connection between the physical WAN interface and the virtual WAN network or the virtual management network.

  • 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
    Patent number: 10545780
    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.
