METHOD FOR OPERATING A NODE CLUSTER SYSTEM IN A NETWORK AND NODE CLUSTER SYSTEM

摘要

The invention relates to a method for operating a node cluster system with a plurality of nodes in a network, wherein the cluster system (100) appears to be a single node with only one specific network address (IP, MAC) to its network environment. The method comprising the steps: providing a shared socket database for linking network connection port identifications of a common set of network connection port identifications to the individual nodes, assigning a master function to one of the nodes, sending incoming traffic to all nodes of the cluster system, wherein each node verifies its responsibility for this traffic individually, exclusive assignment of a network connection port to the responsible node for the duration of a connection of the corresponding application process by means of the corresponding network connection port identification and the link established by the shared socket database, and processing of the traffic by the responsible node or otherwise by the node having the master function. Further, the invention relates to a corresponding computer-readable medium, to a corresponding computer program product and to a corresponding node cluster system.
