摘要：<p>A method (100) transfers packets (60), including ATM cells, through a constellation of satellites (20) in a manner that is nearly transparent from the perspective of an end-to-end virtual connection. According to the method (100), source earth station (50) transmits a connection request to a currently serving satellite (21). The currently serving satellite (21) forwards the connection request to a serving ground control station (40) which then determines which path the packets (60) are routed along corresponding to predetermined time intervals. The serving ground control station (40) transmits the routing information to the source earth station (50) and packets (60) are routed through the satellites (20) using the routing information. Resource allocation information is transmitted to the other ground control stations (51) so that all stations (50, 51) have an up-to-date view of the total network state.</p>
