Title : Fast Reroute using Alternative Shortest Paths

Repair path mechanism is an important element in IP/LDP fast reroute.
In this document we propose a way to calculate local repair paths
using alternative shortest paths. The solution can provide complete
coverage for all destinations within an IGP area that can possibly be
protected.
In this document we also suggested an "Explicit Path with Loose
Segment" model that can be used to characterize, classify, and
analyse repair paths. We proved some of the common properties of
loose segments, and showed that the model can be used to characterize
all existing fast reroute solutions.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
