1. A method for establishing routing of communications via a satellite for an IP-based Demand Assigned Multiple Access (DAMA) Wide Area Network (WAN), said DAMA WAN being characterized by a bandwidth constricted control channel under control of a centralized Network Control Station for communication of channel allocation and routing information to each node in said DAMA WAN, said method comprising:
constructing a network map of all directly and indirectly connected IP network prefixes reachable via said DAMA WAN; and
allocating at said Network Control Station (NCS), DAMA WAN type communication channels via said satellite by a control channel message over said bandwidth constricted control channel directed to each involved subscriber terminal (ST) node connected to said WAN.
