Abstract: A method of communicating via a satellite using a remote apparatus includes determining a geographical location of the remote apparatus, and determining a local data set corresponding to the geographical location. The data set includes communication parameters for a communication conducted by the remote apparatus from the geographical location. The method also includes retrieving the local data set from a global data set stored entirely in a memory of the remote apparatus, and conducting the communication via the satellite by the remote apparatus according to the communication parameters. The global data set includes local data sets corresponding to every geographical location in the world. A corresponding apparatus, a method and apparatus for generating a global data set, and a satellite communication system are also disclosed.

Abstract: Generation of a mapping for use by a data forwarding entity having communication interfaces and instantiating multiple logical forwarding sub-systems associated with respective mappings including a first mapping and a second mapping. The first mapping specifies a next hop interface for data elements received at the interfaces, at least one next hop interface belonging to a set of logical interfaces. The second mapping specifies a second next hop interface for certain data elements for which the next hop interface specified by the first mapping belongs to the set of logical interfaces, at least one second next hop interface belonging to the plurality of communication interfaces. A consolidated mapping is created by replacing each portion of the first mapping that specifies a next hop interface belonging to the set of logical interfaces by a corresponding portion of the second mapping that specifies a second next hop interface.
