A connectionless communications network includes a number of low earth orbit (LEO) satellite nodes. Motion of the satellites constantly changes the topology of the network. A virtual model of the network having fixed virtual nodes, is maintained in a connection control system. This virtual model is used to control the route that traffic will take through the real network. As topology changes happen in the network then the virtual nodes of the model become embodied by different real nodes and communicate their virtual identity to connected nodes. Routing of the traffic is performed with reference to the virtual network so that routing follows the current embodiment of the virtual network. |
