Abstract
A system constructs an OSPF-compatible virtual model of a multi-hop, multi-access packet radio network that includes a plurality of routers (120) and which includes its own private, internal routing system (150), in order to facilitate the incorporation of that packet radio network into an overall OSPF routing environment. The system determines a network graph identifying actual connectivity among the plurality of routers (120). The system constructs a virtual model (300) of the, wherein connectivity of the virtual model may be different than the actual connectivity of the network graph. The system represents the multi-hop, multi-access radio network in the virtual model as a set of multi-access links (305, 310), point-to-point links, AS-external routes, and area summary routes. The system employs the virtual model for routing purposes and advertises the virtual model to other OSPF routers for the same purpose.
