Abstract

Several network node addresses are assigned to at least one link in a network node of a packet switching communications network that contains several network nodes and several links leading to other network nodes. The data-packet traffic that arrives at the network node is divided between the number of configured network node addresses that lead to a target network node and is transmitted.

Claims

1-16. -16. (canceled)

17. A network node of a packet switching communications network, comprising:

a first plurality of network node addresses assigned to a connection path of the network node, the connection path leading to an adjacent network node; and

a data packet arriving in the network node divided between and transmitted to a configured number of network node addresses that lead to a destination network node.

18. The network node according to claim 17, wherein the connection path is associated to a network node interface of the network node, and a second plurality of network node address are assigned to the network node interface.

19. The network node according to claim 18, wherein the first and second plurality of network node addresses are transmitted to the adjacent network node.

20. The network node according to claim 19, wherein a number of the first or second plurality of network node addresses is the same at the adjacent network node.

21. The network node according to claim 20, wherein the first or second plurality of network node addresses present are configured such that each network node address of a network node forms a pair with a network node address of the adjacent network node, whereby the network node and the adjacent network node have the same network proportion.

22. The network node according to claim 21, wherein an individual network proportion is assigned to the network node address pair.

23. The network node according to claim 22, wherein the network node contains a control table in which the connection paths connected to the network node and the network node addresses entered for each connection path are stored.

24. The network node according to claim 23, wherein the network node uses a multi-path routing method.

25. The network node according to claim 24, wherein the network node addresses are Internet Protocol addresses.

26. A method by a network node for traffic distribution of data packets to be transmitted to a destination network node in a packets switching communication network, comprising:

providing a plurality of connection paths leading to other network nodes;

providing a plurality of network node addresses assigned to at least one of the plurality of connection paths;

dividing a data packet traffic arriving in the network node by the number of assigned network node addresses leading to a destination network node; and

transmitting the divided packets towards the destination network node.

27. The method according to claim 26, further comprising sending the network node addresses of a network node that are assigned to a connection path to an adjacent network node.

28. The method according to claim 27, wherein the number of network node addresses set up in the network node per connection path is the same as the number set up in another network node connected at the other end of the connection path.

29. The method according to claim 28, wherein the network node addresses present in the network node and another network node forms a pair, whereby the network node and another network node have the same network proportion.

30. The method according to claim 29, wherein an individual network proportion is assigned to each network node address pair.

31. The method according to claim 29, wherein the network node address are formed using an Internet Protocol address.

32. The method according to claim 29, wherein the network node uses a multi-path routing method.
