Virtual CPE

Customer premise equipment or CPE is used by any enterprise or residential broadband subscriber to connect to the service provider’s network. Service Providers provide, configure and manage CPEs from different hardware vendors for enterprise customers (for business services) and residential subscribers (for multi-play services).

Continuing technology transitions, new service launches, security, privacy and metering requirements make service providers incur significant amount of CAPEX and OPEX to upgrade CPE devices and/or update device software on a regular basis.

Virtual CPE is an alternative way of delivering broadband services to subscribers where most of the CPE functions are pulled in to the operator's network and located near the service edge. In the new network architecture, the CPE acts as a simple Layer-2 forwarding device that helps a business or residential subscriber to connect to the service provider network. Services such as DHCP, Firewall, NAT, Routing, VPN, etc. are delivered by Virtual Network Functions (VNFs) running at the Telco datacenter as a Virtual Machine (VM) instance configured for each broadband subscriber.
