抄録(英) Given that wired network infrastructure is not yet ready in more than half of the world, satellite networks attract attention as an important choice to build global communication networks. Satellite networks must deal by a communication demand of different quantity in every area due to most of the world people live around the equator or in middle latitude area. In addition, distribution of traffic becomes more unbalanced due to population density is different in a city and a district. As a result, the congestion occurs in some satellites, while others are not used at all. The problem about traffic engineering in satellite networks can be solved by scattering traffic over underutilized links. Therefore, this paper proposes a traffic congestion avoidance scheme using Traffic Detour Technique (TDT) which is based on traffic information about a satellite of next hop on the remainder of the path to the destination. The satellite where traffic was concentrated transmits a signaling packet to its neighboring satellites to decrease their sending rate before congestion occurs or packets drop. Neighboring satellites follow it and look for alternate paths of the others which do not include the satellite where a problem occurred. The performance of the proposed scheme is evaluated by simulations. And from the results, this scheme achieves a better traffic distribution and decreases the number of packet drops.
