Title:
ORTHODROMIC ROUTING
Document Type and Number:
WIPO Patent Application WO/2021/238608
Kind Code:
A1
Abstract:
A method and apparatus for routing packets in a network, such as a satellite mesh network. Geographic routing is employed in which packets specify their physical destination location. Network nodes maintain physical location information for nodes, along with routing information, for a limited portion of the network which is local thereto. At each node and for each packet, a target node is selected from the limited portion. The target node may be the node which is closest in orthodromic distance to the physical destination location. Based on the routing information, a next node belonging to the limited portion of the network and located along an available network path between the node and the target node is determined, and the packet is forwarded to the next node.
