Hi-
Does anybody in this newsgroup have any suggestions about how best
to accomplish file transfers between Unix machines connected via T1 
lines that involve a satellite hop?  We have RS/6000's, Suns, and other
types in Dallas and Anchorage with this problem.  The standard 
implementation of TCP/IP doesn't allow for a sufficently large buffer
to accomodate the 1/2 second or so needed for responses to come back.
Thus FTP transfer rates of 75 KBytes/or so are the best I've been able 
to get out of a line that theoretically ought to do 192KBytes or so.

This is after manipulating such parameters as tcp_sendspace, 
tcp_recvspace, mss, etc.

Are there any tricks from the research world, or whatever, that can 
be used to help this problem?

Thanks-
