Definitions

  • the traffic distribution weights determine the traffic load per route for a destination address.
  • the traffic distribution weight is usually a value between 0 and 1, where 0 stands for no traffic and 1 for maximum traffic on a connection or a route.
  • a traffic distribution weight of 1 means that all packets are sent this way.
  • the traffic is divided up based on the weights.
  • the sum of the traffic distribution weights to a destination in a node is therefore 1, i.e. 100% of traffic.
  • Other value systems can also be used for traffic distribution, for example percentages between 0% and 100%.
  • the object on which the invention is based is to improve a method and an arrangement for routing, in particular multipath routing, of data packets in a packet-switching data network in such a way that, if necessary, alternative routes are used for transmission while largely avoiding loops ,
  • FIG. 1 shows a first arrangement for carrying out the method according to the invention
  • FIG. 3 shows a third arrangement for carrying out the method according to the invention
  • FIG. 4 shows a fourth arrangement for carrying out the method according to the invention
  • Figure 5 shows an arrangement of a network node according to the invention
  • a packet that arrives at the network node R1 for forwarding to the destination D is normally always forwarded directly to the network node R2 via the connection L12. Only when the network node Rl determines that the connection L12 has failed is the distribution weight changed locally, for example, and further packets to the destination D are forwarded to the network node R3. The entry in the routing table of the network node R1 would then be accordingly:
  • connection L12 is the primary connection, which is secured by two substitute routes, each via network node R3 or network node R6. Both alternative routes are entered in the routing table of the network node R1:
  • connection L12 fails, the packets are transmitted via one of the two network nodes R3 or R ⁇ or alternatively, for example alternately, via both network nodes or alternative routes.
  • another can be calculated, similar to the example in Figure 2.
  • the traffic distribution weights can be reassigned, for example:
  • the traffic to the destination D in the network node Rl is divided over several routes (multipath routing or multipath routing), according to the following routing table in the network node R1: Knot Rl
  • an alternative route can be used, for example via the network nodes R7, R8, R9 are calculated or determined, according to the example of FIG. 2:
