Abstract

A method for establishing routing for communications using a satellite in a Demand Assigned Multiple Access (DAMA) Wide Area Network (WAN) is disclosed. In one step, Routing Information Messages (RIMs) are received from a plurality of subscriber terminal (ST) nodes at a Network Control Station (NCS). A network map of Internet protocol (IP) network prefixes reachable via the DAMA WAN is constructed using the RIMs. A bandwidth constricted control channel is allocated using the satellite. At least one control channel message is sent over the bandwidth constricted control channel to at least one ST node coupled to the WAN.

CROSS-REFERENCES TO RELATED APPLICATIONS

[0001] This application is a continuation application of U.S. patent application Ser. No. 09 / 822,966 filed Mar. 29, 2001, which claims the benefit of U.S. Provisional Patent Application No. 60 / 196,054 filed Apr. 10, 2000.BACKGROUND OF THE INVENTION

[0002] This invention relates to packet-switched communications via satellite links. A class of communication networks employ packet-switched routing. Typically, linking is established by local communication paths and local traffic management in which the traffic management mechanism is only in communication with those nodes through which traffic is actively passed. Traditional routing approaches are unable to discover routes to nodes for which there is no current active connection. In a demand assigned satellite network, a node may be directly connected to any other node, upon request, but may only be able to support a small number of connections at any time. A mechanism is needed for finding rout...
