When the establishment of a higher priority LSP requires the preemption
of a set of lower priority LSPs, the node has to make a local decision
on the set of preemptable LSPs and select which LSPs will be preempted,
based on a certain objective, in order to accomodate the newly signaled
high priority LSP. The preempted LSPs are then rerouted. This draft
documents a preemption policy which can be modified in order to stress
different objectives: preempt the lowest priority LSPs, preempt the
minimum number of LSPs, preempt the exact required bandwidth in order
to fit the new LSP.

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.
