PWE3

In 2001, the IETF set up the pseudowire emulation edge to edge working group, and this group was given the acronym PWE3 (the 3 standing for the third power of E, i.e. EEE). The working group was chartered to develop an architecture for service provider edge-to-edge PWs, and service-specific documents detailing the encapsulation techniques.

In computer networking and telecommunications, a pseudowire (PW) is an emulation of a native service over a packet switched network (PSN). The native service may be ATM, frame relay, Ethernet, low-rate TDM, or SONET/SDH, while the PSN may be MPLS, IP (either IPv4 or IPv6), or L2TPv3.
