Data packet routing method for packet-oriented data network using routing table for providing alternate transmission paths for each data packet target address

摘要

The data packet routing method uses a routing table at a network node (R1,R2,R3) for providing 2 alternate transmission paths (L12; L13,L32) with respective traffic distribution weightings for a data packet target address, with transmission of the data packet via the transmission path with the maximum traffic distribution weighting and transmission of the data packet with the transmission path with the minimum traffic distribution weighting upon failure of the first transmission path. An Independent claim for a network node for a packet-oriented data network is also included.
