摘要
Abstract
Low-orbit satellites have become a hot topic in satellite network research because of their small transmission de-lay,low link loss,and ability to carry real-time services.Aiming at the network congestion problem caused by the unbalanced load of inter-satellite links in low-orbit satellite networks,a link load state-based multipath routing algorithm(LSMRA)is proposed.LSMRA uses the constellation predictable topology as the basis for route calculation,dynamically adjusts the link weight according to the traffic demand,and avoids the congested link when calculating the route.It adopts the idea of multi-path routing,and makes routing adjustment according to the link load status.Routing calculation,load balancing,routing judgment and other mechanisms are integrated to respond to business load changes in a timely manner.The simulation results show that,compared with the previous algorithms,LSMRA effectively reduces the end-to-end transmission delay of services and relieves the congestion of satellite net-work links.关键词
