In this paper, we propose a predictive and transient congestion control scheme for satellite systems that supports on-board packet switching of multimedia traffic with predefined quality of service requirements. The congestion control scheme incorporates the unique characteristics of satellite systems, e.g. large propagation delays, no-onboard buffer, and low computational requirements. The congestion control scheme requires the estimation of the On-Off traffic characteristics (λ, μ) of the traffic sources. These estimated values are used to predict the transient cell loss probability at each downlink. In case the Quality of Service requirements are not met the proposed congestion control scheme determines the control parameters for source traffic shaping or controls the total number of connection in the system.

The numerical results obtained suggest that the proposed scheme is an excellent candidate for real time burst and call level congestion prediction and control in broadband on-board satellite networks.
