Thanks for the reply, but still have some questions ,
read inline please.

If LSP is considered as SVC across MPLS networks, why
could we assume the arrival and lifetime of LSP
conforms to that of telephone networks?  The only
situation I can see: VoIP system which sets
up LSP for each phonecall. But for data communication
network,  self-similarity and heavy-tail
characterizes the network traffic. Although prof.
cleverland showed there is trends to poisson arrival
in their network, but no others report results
alike.  Would you please tell me  at which
level LSP is assumed to work, packet? connection?
session? host-to-host or network-to-network? 
 
 
Thanks a lot.
