Abstract: The invention relates to a method for producing an assembly (1) and to an assembly (1) for distributing data, comprising an input/output device (2) with at least two interfaces (11, 13) for transmitting data between participants (8, 9) connected to the interfaces (11, 13), wherein data cables (3, 4) are provided, via which the respective participant (8, 9) is connected to the interface (11, 13) corresponding to said participant at the completed input/output device (2). The invention is characterized in that a housing of the input/output device (2) is produced in a plastic injection molding method, and in the process a respective end region of the data cable (3, 4) is surrounded by the housing.

Abstract: The invention relates to a distribution module (1) and method for operating a distribution module. A distribution module comprises a housing (2) and a bus connection (3) and multiple device connections (4). Selection means (5), in particular a rotary selector switch, are provided, by means of which one of multiple communication protocols which are stored in a memory within the housing (2) can be manually selected from outside the housing (2). Alternatively, the selection means can also be configured as a DIP switch, membrane keyboard, touchscreen or key switch. The memory is preferably non-volatile. When a protocol is chosen and the controller parameterises the distribution module via said protocol, and a device then starts cyclic data exchange, the ID of said protocol is thereby also stored in a non-volatile manner. Electronic units such as computing units, memories, power supply and the suchlike are accommodated in the housing (2).

Abstract: A private IP address is converted into a public IP address in a communications network without adapting a client software. The conversion of the private IP addresses into the public IP addresses is carried out via a network address translation. The private IP address of each terminal included in a payload of the IP data packet is convertible into a corresponding public IP address and, if necessary, vice-versa.

Abstract: A guaranteeing a quality of service in a decentralized network, wherein at least one first network element at least temporarily provides a service for at least one second network element is provided. The parameters relevant for the quality of service are provided via an authentication of the first network element.

Abstract: There is described a method for locking on or legal interception of encrypted communication connections, preferably in a peer-to-peer network. If all users in a communication network have a digital certificate, a good authentication and an end-to-end encryption of communication data is possible. A modification of network elements is disclosed to nevertheless provide legal tapping from authorized positions. The above can be used on a special tapping mode, in which the keys for all incoming and outgoing messages are provided to an authorized control position.

Abstract: In decentralized networks such as, for example, peer-to-peer networks, services are not furnished by centralized units, but between the network elements. These also carry out access controls and notify the centralized servers of charge registrations of the services utilized. By suitable valid or invalid inquiry messages, it is monitored by using random sampling, whether the peers fulfill their tasks with regard to charge registration and access controls.

Abstract: In peer-to-peer networks, the services are not provided by central units, but the individual subscriber peers provide them reciprocally, with digitally signed data being stored as resources in the peer-to-network. The data can act as non-rejectable data for billing information if they are transmitted to central collection points. For optimization, only the hash values of the data records and appropriate information that is relevant to the billing process are signed instead of the data records themselves.

Abstract: An electric appliance (1) comprising modules (2, 3) that can be juxtaposed to one another and interconnected using bridge elements (4) for transmitting electric signals and operating voltages. The modules (2, 3) and bridge elements (4) are provided with a pair of plug-in connectors (31) and also a pair of mating plug-in connectors (25, 26). The plug-in connectors (31) are each mounted in a cylindrical outer sleeve (36), and the mating plug-in connectors (25, 26) are mounted in cylindrical ducts or penetrations (19). An O-shaped sealing ring or gasket (38) is arranged about the circumference of each outer sleeve (36), so that the O-shaped gaskets (38) are under pressure when the outer sleeves (36) are inserted in the penetration (19) to interconnect the plug-in connectors (31) and the mating plug-in connectors (25, 26).

Abstract: The invention relates to an electric appliance (1) comprising modules (2, 3) that can be juxtaposed to one another and can be connected by means of bridge members (4) for transmitting electric signals and an operating voltage. Said members are provided with two plug-in connectors (31) respectively which can be plugged in adapted mating plug-in connectors (25, 26) of two modules (2, 3) that are arranged adjacent to one another. A cylindrical duct (19) of the module housing (7) is allocated to the mating plug-in connectors (25, 26) respectively. Moreover, the plug-in connectors (31) are provided with an essentially cylindrical outer sleeve (36) respectively. An O-shaped sealing ring (38) is arranged on the circumference of said sleeve. Said ring being under pressure rests on the wall (20) of the duct (19) when the plug-in connector (31) is plugged in.
