Hi,

I was curious if anyone knows which version of TCP is implemented in
today's 802.11/802.11b wireless cards?

Tahoe, Reno, Newreno, Sack, Lite ?

Is there one that is recommended best for wireless implementation that
performs the best?

Thanks.

None. The TCP/IP stack is in the PC hosting the wireless card, the
wireless card looks more or less like any other network card and
basically sends and receives packets (once you get past all the
management stuff, anyway).

With that said, which TCP Implementation is best for wireless then?

This is Usenet, please quote properly.

I've seen a couple of papers that say SACK plus New-Reno does pretty
well for wireless links. The major feature of wireless links are
packet losses, both singletons and in large bursts, a TCP
implementation that handles those well will likely to well over a
wireless link. Best? Sounds like a research project to me...

Mind you that the performance of the TCP connection over the wireless
link is affected by the TCP implementations at both ends of the
connection, so to do best, you'd want SACK+New-Reno on both the client
with the wireless connection and the server it's talking to (assuming
the typical placement of the wireless link).
