The customer edge device is typically a router, that sits at a customer site on MPLS networks and connects to a provider edge router (PE router) to take communications from a customer site to a provider side. Multi-protocol Label Switching (MPLS) is a protocol-agnostic routing technique designed to speed up and shape traffic flows across wide area- and service provider- networks. It’s a way to insure reliable connections for real-time applications by establishing pre-determined, highly efficient routes. MPLS users two important terms in context: customer edge (CE) and provider edge (PE).

A CE router ( customer edge router ) is a router located on the customer premises that provides an Ethernet interface between the customer’s LAN and the provider’s core network. CE routers, P (provider) routers and PE (provider edge) routers are components in an MPLS (multiprotocol label switching) architecture. Provider routers are located in the core of the provider or carrier’s network.

Provider edge routers sit at the edge of the network. CE routers connect to PE routers and PE routers connect to other PE routers over P routers.
