For IP services, the standard customer interface is either a 10/ 100BaseT Ethernet interface or a gigabit Ethernet interface. These well-established protocols can operate over wired or optical fiber interfaces. Multiple traffic streams can share a single network interface—packets for each destination receive VLAN (virtual local area network) tags and can easily be separated at the entry point to the network. In many instances, all of the services for a particular customer are routed through a single CPE (customer premises equipment) router at the customer's end of an Ethernet link to the carrier, which connects directly to a PE (provider edge) router located in the carrier's facility.

Furthermore, the MPLS technology has its terminologies, which help understand the working of this technology. These terminologies have vital roles to play in the working process of MPLS technology. The MPLS domain is the most common terminology, which means the continuous set of nodes that operate MPLS technology. The routers in the MPLS network are given different names like Provider (P), Provider Edge (PE), and Customer Edge (CE). The router located at the edge and connected to the customer edge is called the Provider edge router, while the customer routers directly connected to the PE are called the Customer edge router. All other routers in the MPLS domain are called Providers.
