[ns] About wireless bandwidth
Mon, 15 Oct 2001 12:49:10 +0800
I calculate the TCP packet seq. numbers as the rate.
For example,set TCP PacketSize=1000bytes , time=Ts
rate=--------------------- = x bps
The calculate rate with such method is the rate of application ?
Besides, I run the simulation in wired network and set link bandwidth 2Mbps.
Its rate can achieve 2Mbps. Why? The overhead doesn't exist in wired ?
