The present invention relates in general to software design and system architecture for a telecommunication node, and more particularly, to a software development, system architecture and message distribution function in a data telecommunication network node for supporting a large number of subscribers in an optimal and efficient fashion. A method and system is provided for routing at least one message from one or more subscribers of a communications network in a network node, the network node having a plurality of processing cards (Pcards).
