Lucy,

	That's a possibility, but not really necesssary.  It
might simply be the case that a network operator wants it
to work this way...

--> --> directly to get the path information and send service 
--> request to the
--> --> head-end node. The request flow seems different from other 
--> --> the four models.
--> --> Is it better to keep the consistency?
--> --> We could have NMS based service request to go head-end node

--> --> head-end node send request to PCE, thus all models will
