Claim 0:
1. A method for managing a link state database in a network, comprising, by a network node of a communication network with dynamically changing topology:
maintaining 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, said higher latency being due at least in part to active inhibition of notifications indicative of the network status information by one or more other network nodes; and
updating 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.
