Abstract: The provision of multimedia services via a non-geostationary satellite system requires advanced traffic engineering procedures. It includes adaptive routing, adaptive forwarding and appropriate signalling. In this study, we evaluate the impact of different signalling procedures on the performance of a network. The signalling procedures were used in conjunction with traffic class dependent routing, smoothed link-cost functions and adaptive forwarding alleviates the oscillations in the traffic distribution. The performance of the proposed signalling procedures is evaluated in two different traffic load scenarios. The simulation results are presented in terms of the average packet delay in the network and the average normalized data throughput. The simulation results indicate that the proposed triggered signalling significantly decreases the signalling load, while the network's performance is not deteriorated in terms of packet delay and data throughput.
