Abstract:
A distributed hash table is implemented to store routing information on a network. Node IDs exchanged in connection with implementation of a link state routing protocol are used as keys in the distributed hash table, and routes are stored at one or more nodes on the network. When a route is learned, the route is processed against the set of keys to determine which nodes should store the route. When a route is needed, the route is processed against the set of keys to determine which nodes should have the route information. The manner in which the route is processed against the set of keys is the same in both instances, so that the DHT may be used to store and retrieve route information on the network. The DHT may be implemented to store MAC addresses, IP addresses, MPLS labels, or other information of interest to enable routes to be stored and learned by network elements on the network.
