Abstract Abstract
This document provides a framework for the development of IP This document provides a framework for the development of IP
fast-reroute mechanisms which provide protection against link or fast-reroute mechanisms which provide protection against link or
router failure by invoking locally determined repair paths. Unlike router failure by invoking locally determined repair paths. Unlike
MPLS Fast-reroute, the mechanisms are applicable to a network MPLS Fast-reroute, the mechanisms are applicable to a network
employing conventional IP routing and forwarding. An essential part employing conventional IP routing and forwarding. An essential part
of such mechanisms is the prevention of packet loss caused by the of such mechanisms is the prevention of packet loss caused by the
loops which normally occur during the re-convergence of the network loops which normally occur during the re-convergence of the network
following a failure. following a failure.
