Abstract: The invention relates to a method for computer-implemented monitoring of a goods delivery from a seller to a buyer by using an access-restricted DLT system. The DLT system comprises a first DLT node assigned to the buyer and a second DLT node assigned to the seller. In addition, the DLT system provides at least one smart contract with program instructions for entering and checking delivery orders, order confirmations, and outgoing goods logs in the course of goods deliveries from the seller to the buyer, and for validating the goods delivery. The method comprises, for example, initialising the goods delivery in the DLT system, for example, logging the goods delivery in the DLT system and/or, for example, validating the goods delivery in the DLT system.

Abstract: In the future, integrated wideband networks, especially the arrangement of switching networks and switching network controls, will be of particular importance. To avoid bottle-necks in the switching network a number of different measures or combinations thereof are taken. These measures include that: a) the transfer rate of the switching network is enlarged by a structural change; b) the switching network is multiplied; c) the input buffers are re-arranged; and d) the allocation strategy is changed.

Abstract: With the aid of a traffic simulator telephone exchanges can be tested, the simulator imitating the traffic conditions in the exchange. To that end, the traffic simulator of the invention comprises, in addition to circuit means for simulating subscriber and line behavior, a program-controlled control arrangement connected thereto which generates random variables such as call distances, call durations and reaction periods, controls the test run and checks the reactions of the exchange, and also mixes the exchange-technical parameters. To obtain a realistic picture of the traffic conditions, a plurality of subscriber and line simulation are provided which are changeable in dependence on the reaction of the exchange. On the basis of the exchange reaction (signifying an event) a realistic picture of the external conditions of the exchange are obtained by linking such reactions with random variables and event instants.
