Re: [ns] how to compute TCP's throughput

[Aashish Patil <aashishp@usc.edu>]

Hello,

You can calculate the tcp thruput at the source in the following manner,
#the following gets the total bytes sent by the tcp source
 set total_sent_tcp_src_1 [$tcp_src_1 set ndatabytes_]
#the followig gets the total bytes retransmitted by the source
        set total_ret_tcp_src_1 [$tcp_src_1 set nrexmitbytes_]
#thruput is then the (total bytes sent - total bytes retransmitted)/time

Thanks.
