filter, and the upstream repeaters are fed by a low-pass filter. If too many people are fielding home servers, it affects everyone.
So DOCSIS has a technical limitation which may or may not apply. This is reasonable justification for limiting upstream bandwidth, not for specifying that users can't run servers. If users can run servers effectively in the limited available upstream bandwidth, then there is no _technical_ reason to prevent them.
how are 'servers' (smtp/web/ftp/imap) different than the existing P2P apps? Wouldn't a cable provider, if the decision was based on upstream bandwidth sharing alone, care MORE about P2P than 'servers' ?
Other last-mile technologies provide symmetric bandwidth yet providers still prohibit servers; this is clearly a business issue, not a technical one.
Correct, or so it would seem... the cable modem providers can charge you more for a 'business class' service, which allows 'servers' to be hosted. --Chris (formerly chris@uu.net) ####################################################### ## UUNET Technologies, Inc. ## ## Manager ## ## Customer Router Security Engineering Team ## ## (W)703-886-3823 (C)703-338-7319 ## #######################################################
