DISCOVERY OF DISCONNECTED COMPONENTS IN A DISTRIBUTED COMMUNICATION NETWORK

摘要

A system, method, and network node for discovering network nodes and management information distributed in different strongly connected components, SCCs, (21, 22) in a traffic network (10). When a network node in a first SCC (21 ) receives a request at an application layer (13) for network management information, the node determines whether it can reach other nodes at the application layer. If not, the node utilizes a functional overlay layer known as the Data Discovery and Distribution, D³, layer (12) to identify and select a set of neighboring nodes to receive the request. The selection procedure provides good probabilistic guarantees that the selected neighbors will include at least one neighbor in a different SCC (22). The node sends (37) the request to the selected neighboring nodes at the D³ layer (12).
