Claim:
1. A method for channel bandwidth estimation, comprising the steps of: receiving a packet at a receiver and noting a timestamp of the packet; calculating an inter-arrival time comprising the elapsed time between the timestamp noted for a previously received packet and the received packet; if the inter-arrival time is less than a configurable minimum and the packet is therefore closely spaced, adjusting a counter of closely spaced packets, else resetting the counter of closely spaced packets; checking for the following criteria, all of which have to be true for a current packet to be part of a packet burst for use in bandwidth calculation: if all the foregoing criteria are true, then determining if burst tracking is currently on, wherein if tracking is on, updating a burst tracking counter and waiting for another packet to arrive; else starting burst tracking, updating said burst tracking counter and waiting for another packet to arrive; and if not all the foregoing conditions are true, checking to see if burst tracking is currently on wherein: if tracking is on, and if tracking is not on, waiting for another packet to arrive.
