Title:
METHOD AND APPARATUS FOR NETWORK ROUTING USING MULTIPLE DEGREE OF PRECISION GRAPH
Document Type and Number:
WIPO Patent Application WO/2022/143172
Kind Code:
A1
Abstract:
A method and apparatus for routing packets in a network, such as a satellite mesh network. Network nodes maintain network status information (e.g. link availability information) for the entire network. However, the information is maintained to a higher level of precision for some network regions than for others. For example, the network node can be informed of network events in some regions with lower latency than in other regions. Routing information is generated based on the network status information. Multiple different mechanisms can be used to provide network status updates at different levels of precisions. Nodes which generate or relay network status updates can inhibit (e.g. block or delay) passing the updates toward a target node in order to reduce the level of precision of network status information at that target node.
