  • Protocol for multicasting in a low bandwidth network
    Patent number: 9019981
    Abstract: A modified protocol independent multicast (M-PIM) routing protocol is an improvement to protocol independent multicast (PIM) routing protocol. M-PIM is optimized for use with at least one low bandwidth multi-hop network. The improvement comprises at least one modification to PIM that facilitates the transport of multicast traffic in a multi-layer routing system.

  • Systems and methods for constructing a virtual model of a multi-hop, multi-access network
    Patent number: 7983239
    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.

  • Systems and methods for forming an adjacency graph for exchanging network routing data
    Patent number: 7881229
    Abstract: A system for exchanging routing information over a communications network constructs a connectivity graph that indicates connectivity between a first node and a first set of nodes in the network. The system constructs an adjacency graph that indicates a second set of nodes with which the first node will exchange routing data, where the adjacency graph is distinct from the connectivity graph. The system exchanges routing data between the first node and each node of the second set of nodes based on the adjacency graph.

  • Systems and methods for synchronizing multple copies of a database using datablase digest
    Publication number: 20040246902
    Abstract: A system uses database digests to synchronize routing data in a network (100). The system includes a first node (110-1) and a second node (110-2). The first node (110-1) stores first routing data and the second node (110-2) stores second routing data. The second node (110-2) further performs a function on a portion of the second routing data, where the function produces a database digest that has substantially less data than the portion of the second routing data. The second node (110-2) also sends the database digest to the first node (110-1) to synchronize the second routing data with the first routing data.
