A network function virtualization (NFV) cloud which provides virtual customer premises equipment (vCPE) services to a customer and is located at a local telecommunication office, the NFV cloud comprising at least one compute node, a local area network (LAN) switch, a wide area network (WAN) switch, a line concentrator switch, and a router,
- wherein each of the at least one compute node comprises:
- at least one vCPE service having a LAN virtual interface and a WAN virtual interface, respectively;
- a LAN virtual network coupled to the LAN virtual interface of the at least one vCPE service;
- a WAN virtual network coupled to the WAN virtual interface of the at least one vCPE service;
- a LAN physical interlace coupled to the LAN virtual network and the LAN switch;
- a WAN physical interface coupled to the WAN virtual network and the WAN switch;
- and
- a service manager controlled by an orchestrator for managing at least two NFV clouds including the NFV cloud,
- wherein the line concentration switch transfers customer traffic flowing from the customer to the LAN switch, transfers the customer traffic directly to the router, transfers the customer traffic directly to the router, or outputs the customer traffic to the router or outside through a predetermined tunneling under a control of the service manager.
