A collection of methods, which when combined together provide suitable bandwidth resources for real-time content exchange over a satellite-based network, wherein the network employs a reservation-based access scheme, such as but not limited to DVB-RCS. Furthermore, the methods provide suitable bandwidth wherein transmission conditions deteriorate while real-time content is being exchanged and the already allocated resources can no longer be used.

Real-time sessions quality-of-service over reservation-based access

A single, large-scale satellite access communication network may be configured as infrastructure for many small-scale subnets, wherein each subnet may be configured to serve a different organization (e.g. an SME) as a private network. Each subnet may be configured as a small star and/or mesh satellite data access network from the end-user perspective, yet all subnets may be configured to be part of the total large-scale network and share satellite bandwidth resources. Such configuration may yield significantly higher bandwidth efficiency, lower operation and equipment costs, minimized latency and ease of network operations for each of the small organizations sharing the large-scale network.

Statistical multiplexing in satellite communication networks

A satellite communication system comprising a hub and plurality of terminals may be divided into multiple segments, wherein each segment may support part of the terminals. A method for decentralized balancing of traffic between the system segments is presented herein. One segment in each coverage beam may be designated as home carrier and include load balancing information. The terminals may be configured to tune on a home carrier, receive the load balancing information and then use it for selecting a least loaded segment on which they may remain operational until reset or powered off. In some embodiments of the invention, said load balancing information may be used for calculating relative probabilities for selecting segments through a weighted random selection algorithm.

Load balancing

Method and apparatus for dynamically optimizing the transmission level of each remote terminal in a satellite-based communication network. Each remote terminal maintains quasi-error-free communication at the highest efficiency level available under changing link conditions and network configurations, without requiring the reservation of substantial power margins, which results in a much more efficient satellite network.
