This document describes a framework and several scenarios for a
pseudowire (PW) dual-homing local protection mechanism that avoids
unnecessary switchovers and does not depend on whether a control
plane is used.  A Dual-Node Interconnection (DNI) PW is used to carry
traffic between the dual-homing Provider Edge (PE) nodes when a
failure occurs in one of the Attachment Circuits (AC) or PWs.  This
PW dual-homing local protection mechanism is complementary to
existing PW protection mechanisms.

This document is a product of the Pseudowire And LDP-enabled Services Working Group of the IETF.
