Hi, I was wondering how I can set up NS so that the packets from
s1 and t1 goes to the same queue in s2 (s1 is sending packets to s3
and t1 is sending packets to t2).  I have done some test and it seems
that the packets going from s1 to s3 and packets going from t1 to t2
are using different queues when they arrive at s2.  Is there a way to
make
these packets go to the same queue in s2?  Thanks.
