    Thomas:

    As an addendum to Fred's note ...

    We did some testing about a year ago with the NetManage FTP Software
    product. It is a third-party TCP stack for Win98 that supports RFC1323. See
    to recall that we were getting something like 120 Mbps single-stream over a
    GEO delay simulator. It is my understanding that NetManage has most of the
    'knobs' to tweak the TCP parameters (window size, timers, etc.) exposed to
    the user, so this should be relatively straightforward.

    Good luck.

    Subject: bandwidth on VSAT transfer

    Hi from France.

    we are testing the Comsat VSAT solution (linkway 2000) but we have a
    limitation about the bandwidth on a TFTP, FTP and RTSP transfer.

    for instance, on an FTP or TFTP transfer, we are up to 80 kbps on each to
    session. That is to say, if I open 4 FTP sessions, I am able to transfer 4
    different files at each 80 kbps.
    The purpose is to be able for me to transfer in one session up to 2 Mbps (my
    bandwidth on the sattelite)

    I am using Windows 98 on each point of the connection.

    Is anybody can help me ?
