<p><P>PROBLEM TO BE SOLVED: To provide a method and system of estimating the bandwidth over a network path. <P>SOLUTION: A new system and method of available bandwidth estimation applies, even where the narrow link and tight link in a network path are in different locations. In an embodiments of the present invention, a unique packet probe series structure and processing is employed to estimate available bandwidth. In one embodiment of the present invention, the spacing between probe packets is adjusted at the source, to account for dilation caused by links leading to a tight link, so that the spacing becomes appropriate, when the probes arrive at the tight link. Moreover, the multi-packet probe comprises a large packet, followed by two far smaller packets. The large packet is then dropped, once it has traversed the tight link. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
