Implications for universities

If a site has a 512 kbps connection to the Internet , the default TCP/Ip settings are likely sufficient , because a 64KB window size can fill up to 984 jbps . But if the university has more than 984 kbps , it might in some cases not get the full bandwidth of the available link due to the "long fat pipe network " factors discussed above . What these factors really imply is that they prevent a single machine from filling the entire bandwidth . This is not a bad thing during the day , because many people are using the bandwidth . But if , for example , there are large scheduled downloads at night , the administrator might want those downloads to make use of the full bandwidth , and the "long fat pipe network " factors might be an obstacle . his may also become critical if a significant amount of your network traffic routes through a single tunnel or VPN connection to the other end of the VSAT link .

Administrator might consider taking steps to ensure that the full bandwidth can be achieved by tuning their TCP / Ip settings . If a university has implemented a netowrk where all traffic has to go through the proxy ( enforced by network layout ) , then the only machines that make connections tot he Internet will be the proxyand mail servers .
