METHOD TO CONTROL SERVICE FUNCTION CHAINING FOR NETWORK SERVICE OF VIRTUAL CUSTOMER PREMISES EQUIPMENT

摘要

The present invention relates to a method to control service function chaining (SFC) for a network service of virtual customer premises equipment (vCPE), capable of largely reducing a total cost of ownership (TCO). According to the present invention, the vCPE comprises: at least one network service corresponding to each service function (SF); at least one virtual network interface card (vNIC) corresponding to a service function forwarder (SFF) connected to at least part of the at least one network service; and a manager corresponding to an SFC classifier analyzing a received traffic, referring to a predefined policy to determine a service function path (SFP) for the received traffic, and transferring the received traffic to the vNIC in accordance with the determined SFP to process the received traffic in a corresponding network service of the network services.;COPYRIGHT KIPO 2018
