Resource matched topology database synchronization in communications networks having topology state routing protocols

摘要

A method for selecting a neighboring node to synchronize network topology database information with a network node from among a plurality of neighboring nodes coupled to the network node in a network, the method comprising: receiving from each of the neighboring nodes an identifier and an indication as to whether synchronization resources have been assigned to the network node; comparing by magnitude the identifier of the neighboring node with identifiers of others of the neighboring nodes to determine whether to synchronize with the neighboring node; and, synchronizing with the neighboring node if the neighboring node has assigned synchronization resources to the network node.
