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.

Abstract: A method is proposed for operating a network with multiple subscribers in the network. For this purpose, a network having at least one switch (20, 21), at least two terminals (10, 11, 12) and a controller (30) is provided. According to the invention, one of the subscribers now sends and/or receives data to another subscriber via an application protocol, with the data being sent and/or received as a TSN data stream. In order to integrate non-TSN-capable nodes in the network, it is proposed that the TSN data stream be divided into at least two partial data streams (1, 2, 3, 4). Such partial data streams (1, 2, 3, 4) can be configured across non-TSN-capable subscribers or between such subscribers.

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 which is transmitted through the firewall to a recipient is assigned a time budget for processing in the firewall. After the time budget has expired, the firewall performs a firewall action for each data packet, which can be executed as sending to the recipient or discarding the packet. The time budget may be less than the processing time required by the firewall to completely process all filter rules, and thus forms a termination condition for processing the data packet in the firewall.

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 which is transmitted through the firewall to a recipient is assigned a time budget for processing in the firewall. Each data packet is then transmitted to the recipient through the firewall only after the time budget has expired. The time budget is defined based on the maximum possible processing time in the firewall.
