LINK-STATE ROUTING METHOD FOR ROUTING DATA STREAMS IN A MESHED NETWORK COMPRISING NODES CONNECTED BY THREE-STATE LINKS

摘要

A link-state routing method for routing a data stream in a meshed communications network comprising a plurality of nodes connected by links, at least one node of said network comprising a topology table which comprises at least one link, in which the node implements: a step of measuring a parameter relating to the load on said link, a step of comparison of the measured load parameter with a predetermined overload threshold, an overload state being assigned to said link when said overload threshold is exceeded by said load parameter; and a step of distributing an item of information relating to said overload state of said link to at least some of the nodes of said network.
