System for routing incoming connection-less messages to processes which are already handling messages from same source node

摘要

A message distribution arrangement for controlling messages in a communication system comprising a number of nodes. The arrangement has a central distributing unit for routing incoming messages and means for forming a variable local data on structure for arranging data nodes which are able or allowed to send messages, a database for providing the data structure with information on originating nodes, updating means for updating the data structure. An incoming message from a given originating node is examined if any process is running for any message originating from the same node in which case the message is routed to that process. Otherwise a new process is initiated.
