control. The growing popularity of distributed real-time applications increases the demand for QoS-aware messaging systems. In the absence of transmission rate control, congestion may pre-vent a messaging system from meeting its timeliness require-ments. In this paper, we develop an analytic model for con-gestion in data dissemination protocols and investigate the ef-fect of transmission rate on message delivery latency. Unlike previous works, we take into account the processing overhead of receiver buffer overflow, which has a significant impact on the results. A simulation is used to obtain more insight into the problem and to study a number of additional effects ig-nored by the analytic model. The presented analysis can be incorporated into a transmission rate control logic, to enable it to rapidly converge to an optimal transmission rate. 1
