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

摘要

The invention relates to a link-state routing method for routing a data stream in a meshed communication network (3) comprising a plurality of nodes (T1 -T2) connected by links (L1, L2), at least one of the nodes of the network comprising a topology table containing at least one link (L1), in which the node (T1) carries out the following steps: a step consisting in measuring a parameter relating to the load on the link (L1); a step consisting in comparing the measured load parameter with a predetermined overload threshold (M), an overload state being assigned to the link (L1) when the load parameter exceeds the overload threshold (M); and a step consisting in distributing an item of information relating to the overload state of said link (L1) to at least some of the nodes (N2) of the network.
