Method and network node for determining multi-path transmission paths in a packet-switched communication network

The invention relates to method wherein data packets are respectively transmitted between an input network node and a destination network node via various transmission paths which link network nodes in a packet-switching communication network consisting of various network nodes. Multipath transmission paths are determined by initially determining at least two disjunct transmission paths between input and destination nodes. Direct transmission paths are then at least partially established in the direction of the target network nodes between the network nodes contained in the disjunct transmission paths such that at least two paths are respectively created from a network node of a disjunct transmission path in the direction of the target network nodes. Thirdly, other transmission paths leading via other network nodes are at least partially established between the remaining network nodes of the disjunct transmission paths.
