Multi-beam satellite networks can extend the service coverage as deploying the spot beams. It is important to allocate the appropriate resources to multi-beam downlinks to prevent the unnecessary waste of resources due to the inherent limitations of them, such as power, bandwidth, and even the use of a spot beam. In this paper, the authors propose a resource management technique adjusting the bandwidth of each beam, in which the difference between the traffic demand and allocated capacity is minimized. This represents a reasonable solution for flexible bandwidth allocation considering a tradeoff between the maximum total capacity and fairness among the spot beams with different traffic demand.
