Hi,
     I have a doubt regarding the maintainance of queues.

From app we call RAPI's to get reservation of resources.
Suppose parallely other apps which have not requested for
any resources will also will be running.

1. How your TCP/IP stack distinguishes the packets which
   belong to some reservation and packets which have no
   reservation?

Let's suppose for connections which request for resource
reservation have a separate queue and connections which
have no reservation of resources have a different queue.
In this case while sending the packets out who will
demultiplex the packets and queue them to their respective
queues. Either we have to write a process for it or
IP layer will take care of it?

I think we have to maintain separate queues for
  a. Guaranteed service
  b. Controlled-locad service
  c. Best Effort service

At which layer these queues will be maintained?

2. At which layer the actual filteration of RSVP pkts and
   non-RSVP pkts takes place?
