Classification: CPC H | IPC H

Claim 20:
21. A system for managing a link state database in a communication network with dynamically changing topology, the system comprising:
a first network node configured to:
receive or generate an indication of a network event, the network event pertaining to status of a node or link of the network;
transmit, using the network interface, the indication of the network event toward a first one or more other network nodes to notify the first one or more other network nodes of a change in network status with a first level of precision; and
actively inhibit transmission of the indication of the network event toward a second one or more other network nodes to notify the second one or more other network nodes of the change in network status with a second level of precision lower than the first level of precision, such that transmission of the indication of the network event toward the second one or more network nodes is delayed compared to transmission of the indication of the network event toward the first one or more network nodes; and
a second network node configured to:
receive the indication of the network event from the first network node, or via another path or mechanism not involving the first network node, upon the first network node inhibiting transmission of the indication of the network event; and
maintain, based at least in part on the indication of the network event, network status information for a plurality of different portions of the network each of said different portions defined by a different respective set of network nodes and links.
