All,

in the motiviation (section 2) for the
draft-ietf-mpls-soft-preemption-02.txt it
is stated that through the preemption as defined in rfc3209 traffic
on the "to be preempted LSP" is (unnecessarily) abruptly preempted.
The transit traffic is disregarded.
I guess this is true, but isn't the (the most common) case here that
the preemting LSP has a higher priority than the preemepted, and if
you withhold the preemption, waiting for the traffic on the preempted
LSP to be taken care of, you will waste traffic with higher priority
during that wait?
