Abstract: A system comprises a constellation of satellites placed in non-geostationary orbit, user terminals located in a coverage area, and N anchor stations able to ensure bidirectional communications with the user terminals by way of at least one satellite. The system furthermore comprises a network of routers interconnected with one another and to the Worldwide Internet Network, each anchor station is connected to the Worldwide Internet Network by way of a router, and each anchor station comprises a management device for managing the handovers to ensure service continuity for the communications. This management device is able to control the handovers between the successive orbiting satellites progressing over the coverage area, the handovers between anchor stations, or the handovers between simultaneously successive satellites and anchor stations.

Abstract: A method and system for routing channels in which messages are transmitted from a source application to a destination application. The system includes a finite-state machine, source message queues, and a source queue manager for managing the source message queues. The source message queues include a transmission queue for holding a first message for subsequent transmission of the first message from the transmission queue over a first channel to a local queue of the destination application. The method includes: activating the finite-state machine; and performing or not performing a channel routing action, by the finite-state machine, depending on: a channel event having caused the first channel to be started or stopped, a channel sender set for the first channel, and an event type characterizing the channel event as normal or abnormal. The channel routing action is a function of the channel event, the channel sender, and the event type.
