Just curious - when your ISP sells you you some bandwidth, and you resell it to your customers, what actually the bandwidth is? Is that on frames level? IP level? TCP level?
Because - if let's say 256kbit means 256kbit on frame level, then there is much less for the TCP and upper level. If you will install Bandwidth test to customers, they will always complain the line is not as fast as it should be, as bandwidth test measures real (above tcp) data only, and leaves out ip + tcp protocol headers.
So I am just curious, when we are talking about 128, 256, 512kbit etc., what data are we actually talking about?
What about option to include ip + tcp headers into measurements even for TCP test?
