Hi! This is a rookie's question about the internet draft "A conceptual model
of diffserv router".
In the section of PHB compenent, I notice that there is a queue parameter
example:

   QueueSet1:
   Type:        QueueSet
   MaxSustRate: 100 Mbps
   MinGuarRate: 20 Mbps
   Interface:   ifIndex

   QueueA:
   Type:        Queue
   QueueSet:    QueueSet1
   Profile:     Profile1
   MinGuarRate: 2 Mbps
   QueueDepth:  200 kbytes
   Priority:    5

Since minimum guanranteed rate is settled, why do we need the term
"Priority"?
Is it used as the weight of sharing excess network resource? Another
question is
about the term "Profile". Thanx for any answer in advance, and please
forgive me
if the question is really dump.
