Bearing in mind most switches/routers output traffic stats in Bytes and most bills go to customers in GigaBytes, which of the following options are being used by each of us to convert between the two when creating the bill?
A, divide by 1024 * 1024 * 1024; B, divide by 1024 * 1024 * 1000; C, divide by 1024 * 1000 * 1000; D, divide by 1000 * 1000 * 1000.
Telecommunications normally uses powers of 10, e.g. 1 Mbps is 1,000,000 bps, so it is natural to do charging based on powers of 10. (Voice is 8kHz x 8 bits = 64 kbps, not 2^16 bps) Stephen. -- ----------------------------------------------------------------------- Stephen Donnelly BCMS PhD email: sfd(a)endace.com Endace Technology Ltd phone: +64 7 839 0540 Hamilton, New Zealand cell: +64 21 1104378 -----------------------------------------------------------------------
