Signalling issues and call admission control in multimedia satellite networks

In this paper we propose the use of an in-band signalling technique coupled with a distributed connection admission control and traffic resource management scheme, to combat the effects of high-latency in geostationary satellite systems. In-band request signalling is introduced to manage burst-based bandwidth demand from satellite terminals transmitting real-time variable bit rate traffic. Performance evaluation has shown the effectiveness of this technique in guaranteeing the service quality negotiated at connection set-up between the user and the network
