Performance of high-bandwidth TRABOL protocol for radar data streaming

Abstract

TCP-friendly Rate Adaptation Based on Loss (TRABOL) is a high bandwidth overlay transport protocol that dynamically adapts the data transmission rate based on the packet loss feedback received from an end user. TRABOL performs AIMD based congestion control such that transmission rate satisfies minimum and target rate requirements of the end user. Additionally, rate is adapted, while remaining friendly to the TCP cross traffic and efficiently using the bottleneck link bandwidth. This paper investigates the impact of different AIMD increase and decrease functions for congestion control on performance of the TRABOL protocol. A network emulator test bed is used for the performance evaluation, measuring the effectiveness of different AIMD rate control schemes in meeting bandwidth requirements of the end user, TCP-friendliness, bandwidth efficiency, and response time of the protocol.
