My ISP promises speeds of 10 to100 Mb/s which to me is comparable to my local grocer promising 1 fl oz to 1 quart when I buy a quart carton of milk. I'll find out when I get home and the deal is done. Yeah, right - the grocer would never get away with that, but ISP's do. There is reliable, even state certified, software that measures the actual speed of your connection - at the moment of measurement. But I haven't found any such software that measures the quantity of generated traffic, upstream as well as downstream, over time, which is another parameter by which you are expected to choose subscription plan and thus cost. There's 1GB/month plans, 5GB's/month ones etc, but no way that I know of to measure the amount of data actually transferred. So I have to take my ISP's word on wether I have exceeded or stayed within the limit paid for. Again, every house owner or aparment dweller has their own electricity meter, reporting on momentary use as well as use over time but, again, there's no such thing for data traffic generated over time. Or is there?
