CWND CALCULATION

[Harlisya Harun <harlisya@erg.abdn.ac.uk>]

Hi:
    I tried to figure out the cwnd calculation, but do not have
any clue.  Please refer below:

TAHOE
-----
0/cwnd=1.0000/ssthresh=15  \
1/cwnd=2.0000/ssthresh=15   > exponential increase of cwnd
2/cwnd=6.0000/ssthresh=15  /

3/cwnd=15.0667/ssthresh=15  \  I can't figure out how cwnd
4/cwnd=15.1991/ssthresh=15  /  gets these values: 15.0667 , 15.1991 etc
:                                                     For Tahoe TCP, cwnd is
updates
:                                                      according to cong:
avoidance if cwnd
:                                                     is strictly larger than
ssthresh, using:
                                                       (MSS*MSS)/cwnd =
(530*530)/(6*530)

= 88 ?

** Both Tahoe and Reno have the same cwnd ***

RENO
----
0/cwnd=1.0000/ssthresh=15
1/cwnd=2.0000/ssthresh=15
2/cwnd=6.0000/ssthresh=15
3/cwnd=15.0667/ssthresh=15
4/cwnd=15.1991/ssthresh=15

Anyone can help me?

Thank you.
