Available bandwidth has a significant impact on the performance of many applications that
run over computer networks. Therefore, many researchers pay attention to this issue through
the study of the possibility of measuring the available bandwidth,
and disseminating tools for
measuring this metric. We present a method to estimate the available bandwidth for a path,
by building, sending, and receiving probe packets. We measure the time gap between probing
packets before sending and after receiving, then we estimate the available bandwidth. This
method relies on an easy and fast algorithm. Applications can use this method before they
start exchanging data over the Internet.
