Mike, this was a bit misunderstandable as i wrote a few hours ago. traffic management is most important for different services than for different vservers. our "add an module..." requires a) to write such a module (i do not have the time and the knowledge to do so) and b) doesn't solve the problems pointed out here before (ip paket sizes for expample). if you could have a look to our server farm you would see that the "adding hardware" aproach is not our way. ------------------------------------------------ BS Web Services Roedingsmarkt 14 20459 Hamburg Germany info at bsmail.de www.bsws.de fon: +49 40 3750357-0 fax: +49 40 3750357-5 PLEASE USE EMAIL WHERE POSSIBLE Miquel van Smoorenburg To: henning.brauer at bsmail.de <miquels at cist cc: "lir-wg at ripe.net" <lir-wg at ripe.net> ron.nl> Subject: Re: IP assignment for virtual webhosting 11.05.00 17:04 According to henning.brauer at bsmail.de: > Yes, that exactly the way we do it.

Add an apache log module that measures the actual bytes sent out (file size + HTTP headers) - accounting problem solved. > And if you think of Bandwith management - i don't see any > way to do this on an per name-basis, only per ip (and service) is possible > as far as I know.

Use the Apache module mod_bandwidth, or something similar. People tend to buy and install enormous amounts of hardware, solving problems by adding more boxes. While fixing the software is simpler, easier and faster. Mike.
