[ns] goodput calculation

["pawan k gupta" <pawan.g@lycos.com>]

hi all,
to try and calculate goodput, isn't it enough to just find out the largest packet number that was acked by the tcp receiver and divide it by the total number of packets transmitted by the sender.
i found that two such parameters already exists in the ns. these are ndatapack_ and ack_.
according to this goodput of the connection is

(ack_ - 1)/ndatapack_

please correct me if i am wrong.

thanks and regards,
pawan
