Ethernet Virtual Private Line (EVPL) is a data service defined by the Metro Ethernet Forum, providing a point-to-point Ethernet connection between a pair of User–network interfaces (UNIs).
EVPL service is specified using an E-Line service type, very similar to a Ethernet Private Line (EPL) service, via a point-to-point Ethernet Virtual Connection (EVC). However, unlike EPL, EVPL allows for Service Multiplexing, i.e., multiple EVCs or Ethernet services per UNI.
The other difference between the EVPL and EPL is the degree of transparency - while EPL is highly transparent, filtering only the Pause frames, EVPL is required to either peer or drop most of the Layer 2 Control Protocols.
