vCPE refers to a network architecture model that substitutes traditional hardware-based customer premises equipment (such as switches, firewalls, and routers) with software-based alternatives. Under this paradigm, the capabilities and functionalities of CPE run on standardized hardware or in a cloud environment owned by the service provider, allowing them to control their user’s network services remotely.

How Does a vCPE Work?

VNFs form the basis of vCPEs. Most traditional network services, like malware detection, intrusion, session management, switching, and routing, are starting to be modified into VNFs (software functions). These program functions may be controlled via MSP’s network and directed into the user’s standardized x86 hardware, which hosts the vCPE. The network interface devices (NID) that act as the interface between the MSP network and customer premises are vCPE modules powered by MSP’s NFV.

Despite most VNFs still being Virtual Machine (VM) models of legacy appliances, many well-known networking companies, including Nokia, Alcatel, Huawei, and Ericsson, are creating cloud-based VNF solutions for the vCPE. If the MSP wishes, they may push the vCPE program with a microservices or container design. Moreover, traditional services such as switching and routing are often embedded in the vCPE’s software. Yet, the MSP may extend its functionality by providing modules from VNF vendors and controlling them via a VNF cloud platform.
