Several new protocols such as RBUDP, User-Level UDP, Tsunami, and SABUL, have been proposed as alternatives to TCP for high speed data transfer. The purpose of this paper is to analyze the effects of SABUL congestion control algorithm on SABUL performance matrices such as bandwidth utilization, self-fairness, aggressiveness and average packet losses. We propose a deterministic model of SABUL congestion control algorithm and use the model to assess these metrics. Our results explain SABUL throughput oscillations, derive bounds on its aggressiveness/responsiveness, show that SABUL can be self-fair, and identify conditions under which SABUL may experience excessive packet losses. We also validate our model by doing experimental analysis.
