Abstract :
Implementing a TCP-friendly congestion control mechanism is imperative for emerging UDP-based real-time, high-bandwidth applications such as multimedia. VCHILL project for digitized radar data transfer over the Internet is one such application for which a source based TCP-friendly rate adaptation based on loss (TRABOL) algorithm is deployed and shown to be TCP-friendly over applicable timescales. Comparison of the TRABOL-based radar application with other non-congestion controlled UDP flows shows that the application performs better with TRABOL and is fair towards neighboring TCP flows. Implementation of a simple memory-based mechanism as an add-on to the TRABOL algorithm enhances the performance of the application.
