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.
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.

COMPONENT-BASED METHOD FOR WORST-CASE ANALYSIS FOR STREAM-BASED SCHEDULING, CLASS-BASED SCHEDULING AND FRAME PREEMPTION IN TIME-SENSITIVE NETWORKS
A method for improving time planning in time-critical networks is proposed. This is done by means of a computer network with a plurality of network users. To carry out the method, all network users along a transmission path from a network user functioning as a transmitter to a network user functioning as a receiver are first detected. Once these network users are known, the longest possible transfer time for a data stream between any two network users along the transmission path is calculated according to an interference model or an end-to-end model. The longest possible transfer time between a transmitter and a receiver is then calculated by summing the calculated transfer times. This transfer time between the transmitter and the receiver that is calculated in this way can then be taken as a basis for the time planning in the network.

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.
A method is proposed for operating a network having at least one switch, at least two terminals, and a controller. The controller can send data to a terminal via an application protocol, the data BEING sent via data packets within the network's link layer, as is common in a conventional Ethernet network. An additional address is added to the data packets within the data link layer (1) and the switch sends the transmission to the addressed terminal via the address (2, 6). Before transmission to the addressed terminal, the address of the data packets is deleted (3). This creates a virtual automation network within an Ethernet network.

For this purpose, the time slots have a start time and an end time so that they can overlap in different branches of the network. To optimize communication time, the packet sizes (5) can be changed. To avoid wasting bandwidth in the network, the time slots are adapted to the packet size accordingly by changing the start times and the end times (6).

The invention relates to a method of routing in a network. The network consists of a plurality of network nodes. The network may have different interlinks and connections from one network node to the others. An actual topology for the network is thus created. According to the invention, the routing is performed in two phases. First, the number of possible links to the network nodes is reduced in a reduction phase.

In a subsequent routing and time planning phase, an optimized route to a network node in the reduced topology is then calculated.
The invention relates to a method for operating a network using at least one switch, at least two terminals, and a controller. The controller can transmit data to a terminal via an application protocol, and the data is transmitted within the security layer of the network via data packets as is normally the case in a conventional ethernet network. An additional addressing means is added (1) to the data packets within the security layer, and the switch transmits the transmission to the addressed terminal (2, 6) via the addressing means. The addressing means is then removed (3) from the data packets prior to the transmission to the addressed terminal.

For this purpose, the time slots have a time beginning and a time end which can overlap in different branches of the network. In order to optimize the communication time, the packet sizes (5) can be modified, and in order to not waste any bandwidth in the network, the time slots are adapted (6) to the packet size in a corresponding manner by changing the time beginnings and the time ends.

The invention also relates to a method for collecting and processing packet information in said network device, in which the time stamp units (4) generate time stamps of the incoming and outgoing data packets and store them in the memory (12). Th time stamp data aggregated in this way can be forwarded to the ports using packet generation (13) and packet delivery (14).
The present invention relates to a method for distributing configurations of network devices (1, 2, 3, 4, 5, 6, 7, 8). Said network devices are connected to at least one network (11). At least two network devices (1, 2, 3, 4, 5, 6, 7, 8) are connected to the network (11) via ports (9). All of the network devices (1, 2, 3, 4, 5, 6, 7, 8) are moreover provided with a determinable unique identification, and at least one memory (10) assigned to at least one network device (1, 2, 3, 4, 5, 6, 7, 8) is used.

Systems and methods for automatic wireless coupling
Wireless access points may automatically discover each other and establish connections based on accumulated credit values incremented via mutual exchanges of identifiers. A first access point may select a candidate access point for a potential connection, and may maintain a credit value for the selected candidate access point. The first access point may broadcast beacon messages, including an identification of the candidate access point and the credit value. Responsive to detecting a broadcast from the candidate access point including an identifier of the first access point, the first access point may increment the credit value. As each access point continues broadcasting beacon messages, it may increment its credit value for the other access point accordingly. Upon both the first access point's and candidate access point's credit values reaching a predetermined credit threshold, the access points may initiate handshaking protocols, without requiring additional request/response exchanges or verifications of candidate selection.

Determining required processing time of a data network
End-to-end latency in a data network containing a succession of network devices through which a data packet passes via data connections is determined by first providing the data packet with a trigger packet. Then each device generates and adds to the trigger packet a respective reception timestamp indicating when the packet is received by the respective device. This added data indicates time needed for travel from the immediately upstream network device such that, when reaching the furthest downstream device of the succession of network devices, the trigger packet holds a plurality of timestamp representing when the trigger packet was received by the network devices. Finally the end-to-end latency is calculated at the furthest downstream network device from all of the time stamps in the trigger packet.
