METHOD FOR FORWARDING DATA BETWEEN COMPUTER SYSTEMS, COMPUTER NETWORK INFRASTRUCTURE, AND COMPUTER PROGRAM PRODUCT

摘要

The invention relates to a method for forwarding data between secured computer systems in a computer network structure. Data packets are transmitted along a predetermined communication path structure from a source computer system to al least one target computer system by means of a group of task servers, wherein the communication path structure comprises a plurality of parallel partial paths. The source computer system and also the target computer system keep predetermined network ports closed, in such a way that no connection can be externally established to the source computer system or to the target computer system, wherein, however, the source computer system or the target computer system can establish a connection to a respective task server in order to store data packets in the task server or to collect them therefrom. The method has the advantage that a high availability or disaster capability is combined with data security through encapsulated source and target computer systems.
