Abstract
Effective bandwidth of a communication link is determined in a heterogeneous, packet switched network between a source and a destination, where effective bandwidth is defined as the actual available bandwidth between the server and the client, minus the overhead of the various network protocols used to transmit the data. The method includes measuring transmission times between the source and a destination for a plurality data segments having different characteristics, such as different sized files or subfiles of data; processing the transmission times to cancel effects of transmission latencies other than the different characteristics of the data segments; and indicating a bandwidth based on said processing. The processing is done in parallel with the return of user resources to the destination, and using a bandwidth detection engine associated with a proxy server.
