[ns] About Full-traffic flows in NS2

2006-02-19 Thread Hailun Tan
Hi,all: I wondered if there is anyone who ever tested the full-traffic flows in NS2 (i.e: given n nodes in the network, there are n*(n-1)/2 traffic flows running in simulation, which means that there is traffic flow for any two distinct nodes in the network)... I tried it these days and found
