Usually bits when it comes to bandwidth, while usage is counted in bytes. To convert from bits to bytes, divide by 8. To convert from bytes to bits, multiply by 8. A 64kbit circuit supports 8kbyte of throughput. 2mbyte/sec equals 16mbit/sec. But those are true conversions. Overheads etc lower actual throughput. Dividing/multiplying by 10 usually works to give you a roughly more accurate figure. Hope that helps. :-) _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
