Transmitting Data Packets in a Data Network with a Multiplicity of Network Nodes

摘要

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.

1. A method for transmitting data packets in a data network having a multiplicity of network nodes, the method comprising:
a) ascertaining routing topologies for a respective network node in the data network, wherein the respective network node has an explicit identification, and wherein the routing topologies describe paths for forwarding data packets between the respective network node and other network nodes in the data network on the basis of links between adjacent network nodes; b) producing routing information with the explicit identification of the routing topologies that indicate the adjacent network nodes to which the data packet should be forwarded to be received at a destination network node, wherein the routing information is stored in the respective network node; c) transmitting the data packet from the respective network node to the destination network node, wherein the data packet specifies the explicit identification of the routing topology to be used, and wherein each network node that forwards the data packet uses the routing information with the explicit identification of the routing topologies for the data packet.
