Link without queue!

[Kim <kts@gigabitwireless.com>]

Dear ns-users,

There are two kinds of packets (different size in time)
type-1 pkt ****  n0->n1->n2
type-2 pkt ####  n0->n1->n3

at t=t1
              moving right     ------------------- n2
                ###****** ->  /
n0 ------------------------ n1 
                              \
                               ------------------- n3

n1->n2 and n1->n3 links consists of a queue and a delay.
So, after passing n1, the packets is overlapped half
due to the different transmission delay due to the queue for each link.

                              /
n0 ------------------------ n1 
                              \ 
                               ------------------- n3

				******
at t=t3       moving right     ------------------- n2
                              /   
n0 ------------------------ n1   overlapped 
                              \ ###
                               ------------------- n3

But, I REALLY want for packets to work like THIS.
without a queue in each links, what i want is working.

DESIRABLE FUNCTION (after n1, just discriminate the packet according to priority without delay)

                              /
n0 ------------------------ n1 
                              \   ###
                               ------------------- n3

like TDMA, two packets are moving out at different time 
(not overlap,
