Claim 12:
13. A network node comprising a network interface, a processor and a non-transitory memory, the network node belonging to a communication network with dynamically changing topology and configured to:
maintain, using the processor and the memory, 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, wherein said network status information for one of the different portions is updated with a higher latency than said network status information for another one of the different portions;
update the link state database based on the network status information for the plurality of different portions of the network, the link state database indicative of link states within the plurality of different portions of the network, wherein the link state database includes a first portion indicative of link states for said one of the different portions of the network and a second portion indicative of link states for said other one of the different portions of the network, and an indication that the first portion is tracked with a lower precision than the second portion due to said higher latency; and
actively inhibiting transmission of an update to said network status information toward one or more other network nodes.
