Abstract: Method for operating a network (10), wherein the network (10) comprises at least one outer network (12) having at least one network device (14) and at least one inner network (13) having at least one network device (15), wherein additionally a transmission unit (16) is present that blocks a transmission of data from the outer network (12) to the inner network (13) and allows it in the opposite direction (or vice versa), characterised in that the transmission unit (16) permits a transmission of data only from the inner network (13) to the outer network (12) and the at least one network device (15) sends data from the inner network (13) to the transmission unit (16) with a first address, wherein the transmission unit (16) converts this first address into a second address and thereafter the data are transmitted with this second address in the direction of the outer network (12), the second address being a target address for the at least one network device in the outer network (12).

Abstract: A method for operating a network having a plurality of terminals and a plurality of switches connected to one another via data lines has the first step of transmitting a multicast MMRP data packet from a data source via at least one of the switches and one of the data lines to a predetermined terminal intended to receive the multicast data packet. Then one port of a switch to which is connected another terminal that is not MMRP-capable is fed the multicast address as a static entry of the terminal connected to the one port. The multicast address is then transmitted to the at least one switch connected thereto.

Abstract: A crane has a base, an adjustable-length boom pivotal on the base and formed by at least one outer boom element and at least one inner base-mounted boom element telescoping with the outer element, and a cable extending between an outer end of the outer boom element and the inner boom element so as to be pulled out on extension of the outer boom element from the inner boom element. Such a crane is operated by detecting tension in the cable and generating an output corresponding thereto, determining when the tension in the cable is outside a predetermined noncritical range, and taking action to suspend operation of the crane on determination that the tension is outside the noncritical range.

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: The invention relates to a method for operating a network, wherein the network comprises a plurality of network devices having ports, the network devices being connected to one another for transmitting data via cables which are each inserted into a respective port, wherein each port has signaling means which can be switched between at least two signaling states. The invention is characterized in that all signaling means of those ports of the network devices, which have the same configuration, are brought into an associated detectable signaling state.

Abstract: A method of operating a transmission system (1) having a first network (2) and at least one second network (3), data being exchanged between these at least two networks (2, 3) in that data of the first network (2) is fed to duplication means (4), the inputted data being transmitted wirelessly to separator means (5) via at least two transmission paths (6, 7) using PRP and forwarded from the separator means (5) to the connected second network (3), characterized in that the data is transmitted in the form of data packets, and it is ascertained whether or not a data packet was transmitted, and it is determined based thereon whether or not the transmission system (1) is operating in a fault-free manner.

Abstract: 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.

Abstract: Method for operating a network having a prescribable topology, wherein the topology contains a plurality of network devices which are connected to one another and interchange data via multiwire data lines connected to their data ports, wherein test messages are also sent to the data lines in order to check whether or not two data ports on two network devices have the connection between them via the interposed data line, characterized in that, in a prescribable time interval, the number of CRC errors which have occurred and the number of data items transmitted in this time interval are ascertained on a data line between two data ports, and at least these two values are used to calculate an error rate which is a measure of the operability of the multiwire data line.
