Реферат: In this talk, we consider data routing in prospective Software Defined Satellite Networks (SDSN) that provide world-wide telecommunication services. We suppose that the network consists of satellites on low Earth orbit (LEO), ground stations (gates to the Internet) and a Network Operations Control Center (NOCC). The system operates in discrete time frames, which are sufficiently short to assume that the quality of communication channels and the client demands do not change within a time frame. The packet routes for each origin-to-destination pair are computed at NOCC in real time and each node (a satellite or a ground station) regularly receives the updated routes for all packets that originate in this node. Each packet sent from a source to a destination contains some clients’ content data and a path of the packet route. An upper bound on the number of edges in packet paths is imposed due to technical limitations and communication quality requirements.
