METHOD FOR DIVERTING DATA PACKETS WHEN LOCAL LINK FAILURES ARE IDENTIFIED

摘要

According to said method, routing information or a list of routing information is inserted or modified in the packet header of data packets, in response to a malfunction of the packet network, in order to avoid defective nodes or links. The data packets with modified headers are routed using the inserted routing information to avoid the network node that is not available. The routing information inserted in the packet header can be determined via the packet network with the aid of topological information. The invention allows a rapid response to malfunctions. Packet losses and delays in data transmission can thus be avoided immediately after the determination of the malfunction by routers adjoining the malfunction area, whereas in conventional packet networks, a problem-free data transmission can only be restored after the convergence of the modified topological information in the packet network.
