may be this will help network connections are measured in bits (right) and there are eight bits to a byte (right) so the file size needs multiplying by eight or the connection speed needs dividing by eight. to get the actual speed in bytes.
so a 64Kbit line will all 64000/8 = 8Kbytes. So the link will take a maximum of 8K a second. a dual isdn line will be 128000/8 = 16K. that should help make the math balance. ----- Original Message ----- From: "Kevin White" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, January 01, 2002 3:18 PM Subject: [scottish] Web Server on ISDN > Comrades, > > Continuing my quest for ISDN. > > One of the many things i had planned was to host a small webserver over the > ISDN line for the use of a limited number ( 10 ) of people. > > My ( maybe flawed ) logic being that at an average of 5kb per second transfer > , my ISDN line ( being 64kb ) could cater for 10 people accessing the site at > any one time ( 5kb * 10 = 50kb , leaving me 14kb for running my terminal > emulator ). > > However , reading this months Linux Format article on co-location , i came > across the following snippet... > > "its no good trying to use a 64k leased line for a company web server, > because it maxes out at roughly 5.5kb per second.
