Method, system and nodes for network topology discovery in communication networks

摘要

Method for detecting and employing types (4001, 4002, 4003) of network topology in telecommunication networks having a plurality of nodes (a, b, c, d, e), said method comprising the steps of: broadcasting, by a node (b) initiator, a message (M1) discovery to nodes (a, c) adjacent receiving, by said node (b) initiator at least one node (a, c, d, e) additional , results (611, 612) of the answer (M3, M11) of discovery message, characterized by determining, by said initiator node, a type (7100, 7200, 8100, 8200) operating network topology proposed appropriate to operate the network according to the analysis of said initiator node, sending, by said node (b) initiator at least one of said nodes (a, c, d, e) additional, a first message (M5) information which comprising said type (7100, 7200, 8100, 8200) operating network topology proposed, receiving, by said node (b) initiating a second message (M20) information comprising a type (7100, 7200, 8100, 8200) operating network topology proposed additional at least one of said nodes (a, c, d, e) additional, and switching, by said node (b) initiator, a type (11100, 11200, 11300) of operation topology resulting network depending on said type (7100, 7200, 8100, 8200) of network topology proposed, and these types (7100, 7200 , 8100, 8200) proposed additional topology network of said second information (1001, 1002).
