In computer communication networks, routing is often accomplished by maintaining copies of the network topology and dynamic performance characteristics in various network nodes. The present paper describes an algorithm that allows complete flexibility in the placement of the topology information. In particular, we assume that an arbitrary subset of network nodes are capable of maintaining the topology. In this environment, protocols are defined to allow automatic updates to flow between these more capable nodes. In addition, protocols are defined to allow less capable nodes to report their topology data to the major nodes, and acquire route information from them.
