High-speed propagation of link status routing control information
Douglas E. Comer, Rajendra Shivaram Yavatkar · 2002
A link status routing algorithm required each node to know the current status of all the links in the network. Nodes use a link status update protocol that helps in keeping the database at each node up-to-date. The authors describe a link status update protocol designed for a highspeed network. The protocol uses the best-effort model of packet delivery, but is fault-tolerant. It uses an algorithm for fast propagation of link status updates that is optimized for the expected case when no update packets are lost, and no link or node failures occur. The protocol uses a separate mechanism to detect and recover from errors caused by loss of updates and failure of nodes or links.>
