PWE3 (PseudoWire Emulation Edge to Edge) A PWE that operates from the ingress edge to the egress edge of a shared Internet Protocol (IP) or MultiProtocol Label Switching (MPLS) network. PWE3 makes use of existing mechanisms specified by the IETF, exerting no control over the network other than using existing quality-of-service (QoS) or path control mechanisms. See also PWE. |
