TCP-friendly congestion control mechanism for an UDP-based high speed radar application and characterization of fairness

The transfer of digitized radar data over the Next Generation Internet at data rates ranging from 64 Mbps to 384 Mbps, is an emerging real-time, high-bandwidth application using the UDP transport protocol. We propose the TCP-friendly Rate Adaptation Based on Loss (TRABOL) algorithm that relies on relevant QoS parameters feedback from the receiver to the source to control the transmission rate for congestion control. We also characterize the fairness of the system of UDP-based and TCP-based flows sharing a single bottleneck link bandwidth, using a throughput-based fairness index and show by experiments that the congestion-controlled radar application is TCP-friendly.
