Until recently, we had only a 512KB line between our operations facilities here in Brussels and the AMS-IX in Amsterdam. This is why our Network Manager didn't want me to add any news peerings across that link -- even just a GB/day could be a very significant load on that small of a connection. And I've seen some of our customers operating rather popular sites behind ISDN lines. If you tried a high-bandwidth cvsup on a system like that, the copper might melt! ;-) > Agreed.

That's why I suggest a more general solution needs more intelligence on both ends -- not a whole lot on the client side, just enough to have a useful dialog with a server regarding bandwidth, latency, network drops, etc... between the client and the server, the server utilization, the servers knowledge of other servers that exist and serve that information (and the latest information it might have as to their utilization), and the ability to be able to follow the references that are supplied. -- These are my opinions and should not be taken as official Skynet policy _________________________________________________________________________ |o| Brad Knowles, Belgacom Skynet NV/SA |o| |o| Systems Architect, Mail/News/FTP/Proxy Admin Rue Col.
