Abstract
A border gateway protocol (BGP) management system ( ) dynamically determines an optimum or preferred data route ( ) from wireline networks ( ) into a satellite communication system ( ). Multiple gateways ( ) provide access points to the wireline networks. The management system includes a connectivity matrix which processes ( ) information, such as bandwidth availability and route congestion, and then generate a BGP update that is communicated ( ) into at least one of the gateways. The BGP update promotes preferred gateways and so identifies a preferred access path to the satellite system. Specifically, the BGP update instruction contains a metric altering a weighting of an identified route data route, which metric effects path selection at a gateway receiving IP datagrams. The metric is derived from information pertaining to a connectivity matrix associated with the satellite system.
