The invention relates to a system (), comprising at least two asynchronous computers (-), on each of which at least one application (A) is executed, which provides control data (SD) for at least one actuation system (), wherein the provided control data (SD) are transmitted by a control-authorized computer (-) that assumes a master computer status (M-RS) to the actuation system () for the control thereof, wherein the computers (-) of the system () cyclically exchange state data (ZD) and performance data (LD) with each other by means of a data interface in a data exchange (DAS), wherein the computers (-) each determine, on the basis of the state and performance data (ZD, LD) received from other computers (-) and on the basis of the computer's own state and performance data (ZD, LD, in a master/slave selection (MSA) performed on the computer (-), a computer status (RS) as a control-authorized or non-control-authorized computer (-) to be assumed by the particular computer (-) itself.

A method and a network system for communicating confidential measured data between a plurality of decentralized, measured data-generating producers and a consumer in an automation network is provided. The following is carried out on the part of the producers: measuring or providing measured data from a plurality of sensors and classifying the measured data into security levels; checking a reliability of consumer-generated processing instructions depending on the respective classified security level; and in the case of a positive check, processing the measured data on the basis of the processing instructions, proven to be reliable, to generate an analysis result data set; and transmitting the analysis result data set to the consumer.

The Specific service instances are requested by a client via a client application. The request is received by a Domain Name System (DNS). The request is resolved by the DNS by determining from information recorded in a DNS system memory and conveyed in the request, a first type Tof service and a first list Lof service instances associated with the first type T. The DNS then searches for a linked structure in a TXT resource record for the first type T. The linked structure identifies another list Lof service instances associated with a subtype Tof service. Then iteratively, for i=2, . . . , N+1, N being a number of the subtypes of service associated with the first type Tof service, searching a TXT resource record for a linked structure identifying a corresponding subtype Ti of service and identifying a list Li+1 of service instances associated with the subtype Ti+1.

An autonomous network has a plurality of autonomous terminals, equipped with at least one programmable transceiver, and which are embodied to independently identify frequency ranges provided for a communication link and used to reconfigure the programmable transceiver thereof. One or more technical system states of the network, with which a specific operation of the network is described, is defined. One or more sets of rules are defined for the autonomous terminal, one rule comprising authorized operational states and/or configurations of the autonomous terminals. The effects of the actual operation state and/or configurations of the autonomous terminals on the actual system state of the network is monitored. The sets of rules and/or definition of new rules, which comprise actual operational states or configurations of the autonomous terminals, is adapted when the actual system state of the network differs from the defined system state of the network.

A system and a method implements a business model for determining a reliable eco-balance of a specific product. An eco-balance typically has consumption of resources, e.g. water consumption, energy consumption and waste products, e.g. CO2 production. Incoming products and outgoing products having a Radio Frequency Identification (RFID) tag for storing their own ecological balance. A calculation unit for each link of a whole product chain of the specific product, is calculating an aggregated ecological balance from parameters of the process of the actual link and from ecologic balances of incoming products, if there are any, and storing it to the Radio Frequency Identification (RFID) tag of the outgoing product of the actual link.

A respective agent platform in network elements and producer-specific agents that are installed directly on platform or by way of agent proxies of agent providers. The agents then receive raw information on arising operating errors by way of a defined interface of the agent platform, and, together with producer-specific information on the respective terminals or types of terminal that are known only to the respective producer, from corresponding compressed decision information for evaluating cases of error and/or for optimizing reconfiguration decisions. The agents then provide the information for the network element or the network operator and/or the agent provider or the terminal producer, via the defined interface. This leads to a higher reliability of the interoperability of terminals and network elements in mobile radio networks including reconfigurable terminals.
