Abstract: The invention refers to a method and a communication system for transmitting in either direction data between any two devices in a client layer and/or a transport layer of a communication system. The data transmission is performed according to the transport control protocol, referred to hereinafter as TCP. In order to achieve a high data transmission rate it is suggested that central storage means (12) for buffering the data to be transmitted and a TCP protocol operation block (10) are provided within the communication system, wherein the TCP protocol operation block (10) handles references on the transported data stored in the storage means (12) instead of the data itself. The invention also refers to an embedded acquisition device (1) located between the two devices of the communication system, between which the data is to be transmitted. The acquisition device (1) comprises means adapted for performing the method according to the present invention.

Abstract: A method is provided for classifying a data segment with respect to its further processing in a data transporting unit, in particular in a network processor. The data segment is provided by an input interface. A first key for a lookup table is ascertained as a function of an identifier (chid) established in advance and as a function of an identifier (devid) of the input interface from which the data segment stems. A second key for the lookup table is ascertained.

Abstract: A method for setting up an array of technical units and such an array are presented. The method is used for the independent setup and operation of an array of technical units, the technical units being connected to one another via a system communication bus, a query for a system resource being transmitted from a querying unit to all other units, all other units checking whether the resource has already been assigned to this unit itself, and all querying units transmitting an appropriate response to the querying units and the system resource being assigned thereto if it is not already assigned to one of the other units.
