摘要
A method for determining routes for a data circuit between source and destination terminals, where the circuit is formed via satellites traveling in respective non-geostationary orbits, and a total time during which the circuit is active is divided into time intervals. The determination of each route comprises, for each time interval, (i) selecting an uplink satellite to service the source terminal as an ingress node for the circuit, and (ii) determining a series of inter-satellite links connecting the uplink satellite to a downlink satellite servicing the destination terminal during the respective time interval, wherein the series of links is determined to be valid during the respective time interval. Each of the plurality of time intervals is of a duration based on a validity time, based on the satellites traveling in their respective orbits, for the inter-satellite link of all of the routes that is of the shortest duration.
