Data communication system with adaptive routing, and switching node intended to be used in such a system
First Claim
1. A data communication system comprising a plurality of nodes interconnected by links, at least certain of said nodes comprising detection means for detecting neighboring nodes for implementing an adaptive routing function, wherein one of said certain of said nodes comprises recognition means, andresponsive to operation of the data communication system in a connection mode, said recognition means comprises:
- means for transmitting a call request message on at least certain ones of links connecting to said one node,means for establishing a respective session with a given neighboring node, upon reception of such a call request message coming from said given neighboring node, andmeans for transmitting to the given neighboring node a recognition message indicating a double identifier of said one node once a session has been established with the given neighboring node, andat least another of said certain of said nodes comprises respective recognition means.

Abstract
An adaptive routing protocol for a data communication system that operates in the connection mode. Therefore, the nodes have a function of detecting their neighboring nodes, which permits establishing sessions with their neighbors without previously knowing them, so as to transmit to them recognition messages which indicate their own identifier. Each node additionally has a double identifier of which one identifier is formed by the serial number of the node, so that the serial number can be detected in the system before any configuration and this, more particularly, by a terminal dedicated to managing the system entrusted with the remote configuration of the nodes.
