摘要

An arrangement, a system and a method distribute messages in a communication system supporting communication of packet data. The arrangement includes a number of processors communicating with each other. Each processor is connected to all other processors via at least two physically separate networks. For each processor, information holding devices are provided for keeping information about all communication paths to all other processors. For obtaining information, first messages are sent from each processor to all other processors using all of the at least two networks.
