This document specifies a mechanism for protecting pseudowires (PW)
against egress attachment circuit (AC) failure and egress PE failure.
Designed on the basis of multi-homed CE, upstream label assignment
and context specific label switching, the mechanism enables local
repair to be performed immediately upon a failure. In particular,
the router at point of local repair (PLR) can redirect PW traffic to
a protector PE via a bypass LSP in the order of tens of milliseconds,
achieving fast protection that is comparable to MPLS fast reroute.
