Prioritization For Time-Deterministic Firewalls

Abstract

The invention relates to a method for allowing data packets in a network to arrive at the recipient at definable times. The method requires a firewall in a computer network. Each data packet is processed within the firewall according to filter rules. Each data packet which is transmitted through the firewall to a recipient is assigned a prioritization for processing in the firewall. Each data packet is transmitted after the filter rules have been processed, but this transmission can be interrupted as soon as another data packet with a higher prioritization arrives at the firewall. The data packet, the processing of which was interrupted, is then stored in the buffer for processing at a later time.
