Abstract

Systems and methods for transmitting data packets in a data network comprising a multiplicity of network nodes are provided. A routing topology associated with a respective network node is ascertained, wherein the routing topology describes paths for forwarding data packets between the respective network node and each other network node in the data network on the basis of links between adjacent network nodes. A piece of routing information with the identification of the respective routing topology is produced and is stored in the respective network node. A data packet transmitted from a source network node to a destination network node specifies the identification of the routing topology to be used for the transmission, wherein each network node that forwards the data packet uses the routing information stored on each network node with the identification of the routing topology for the data packet.
