This document describes a Virtual Private LAN Service (VPLS)
solution using pseudowires, a service previously implemented over
other tunneling technologies and known as Transparent LAN Services
(TLS).  A VPLS creates an emulated LAN segment for a given set of
users; i.e., it creates a Layer 2 broadcast domain that is fully
capable of learning and forwarding on Ethernet MAC addresses and that
is closed to a given set of users.  Multiple VPLS services can be
supported from a single Provider Edge (PE) node.

This document describes the control plane functions of signaling
pseudowire labels using Label Distribution Protocol (LDP),
extending RFC 4447.  It is agnostic to discovery protocols.  The data
plane functions of forwarding are also described, focusing in
particular on the learning of MAC addresses.  The encapsulation of
VPLS packets is described by RFC 4448.  [STANDARDS TRACK]
