trace...

["Kartik Sudeep" <skartik@hotmail.com>]

I am trying to the run the test suites for RED using 2 ftp sources.

the topology is :

#        s1                 s3
#         \       RED       /
# 10Mb,2ms \  1.5Mb,20ms   / 10Mb,4ms
#           r1 --------- r2
# 10Mb,3ms /               \ 10Mb,5ms
#         /                 \
#        s2                 s4

        set tcp1 [ns_create_connection tcp-reno $s1 tcp-sink $s3 0]
        $tcp1 set window 15

        set tcp2 [ns_create_connection tcp-reno $s2 tcp-sink $s3 1]
        $tcp2 set window 15

        set ftp1 [$tcp1 source ftp]
        set ftp2 [$tcp2 source ftp]

The trace file does not list any packet of the type "ACK". There are only 
TCP packets, each of length 1000. Is this how the trace is supposed to 
function ? Why does it not enlist any ACK packet at all ?
