A device for processing data, including at least two data interfaces, a first data interface of the at least two data interfaces being designed to at least temporarily exchange first data with at least one first external unit according to a first communication protocol, in particular CAN and/or FlexRay and/or LIN and/or MOST and/or Ethernet, a second data interface of the at least two data interfaces being designed to at least temporarily exchange data with a second external unit and/or the first external unit according to a second communication protocol, which is different than the first communication protocol, the device including a security unit, which is designed to at least temporarily carry out at least one security function with regard to at least one of the at least two data interfaces.

Device for processing data including at least two data interfaces, and operating method therefor

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 () for buffering the data to be transmitted and a TCP protocol operation block () are provided within the communication system, wherein the TCP protocol operation block () handles references on the transported data stored in the storage means () instead of the data itself. The invention also refers to an embedded acquisition device () located between the two devices of the communication system, between which the data is to be transmitted. The acquisition device () comprises means adapted for performing the method according to the present invention.

A bus interface unit for exchanging data via a bus system includes at least one bus control unit for connection to the bus system, having a control unit that is configured to output data received via the bus control unit from the bus system, and/or data derived therefrom, to an external unit, and/or to output data obtained from an external unit, and/or data derived therefrom, via the bus control unit to the bus system.

Bus interface unit and operating method therefor

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.

Method for classifying a data segment with respect to its further processing

In a method for classifying a data segment with regard to its further processing in a data transport unit, which data segment includes a header information of a data packet of an encapsulated network protocol, a parameter for the further processing of the data segment is ascertained as a function of a table entry in a lookup table that corresponds to an ascertained key for the lookup table.

Method for classifying a data segment with regard to its further processing

A method for selecting one of several queues and for extracting one or more data segments from a selected queue for transmitting with the aid of an output interface includes: selecting the output interface by a first scheduler; selecting a number of queues by a second scheduler; selecting one queue from the number of queues by a third scheduler; and sending one or more data segments from the selected queue to the output interface for transmission.

Method for selecting one of several queues

A gateway module for connection of at least two sub-networks is described. A first sub-network of the at least two sub-networks supports a data transmission in accordance with a first communications protocol, especially CAN, FlexRay, LIN, MOST or Ethernet, and a second sub-network of the at least two sub-networks supports a data transmission in accordance with a second communications protocol, especially CAN, FlexRay, LIN, MOST or Ethernet. The gateway module has a configurable hardware circuit which is adapted to manipulate and forward data from the first sub-network and to the second sub-network taking into consideration the first communications protocol and the second communications protocol.

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.

Method for setting up an array of technical units

A method of reconfiguring a data unit communication network that comprises bridge nodes is described. Each bridge node comprises two or more ports for receiving and sending data units, a controller for controlling said bridge node and for handling received data units, and a record for associating data unit address information with port identification information. The controller is capable of querying said record for determining which one or more ports to forward a received data unit to. The method comprises performing a topology reconfiguration procedure for said data unit communication network when detecting an occurrence of any one of one or more topology reconfiguration conditions, and performing a purge procedure of the records of the bridge nodes when detecting an occurrence of an indication of an upcoming topology reconfiguration of the data unit communication network, the indication being different from any of said topology reconfiguration conditions, and continuing to handle data units in the bridge nodes during the purge procedure.

Network reconfiguration method

A network bridge comprising two ports for connection to two networks, a spanning tree controller and a wireless bridge link controller for each port. The ports employ an adaptive modulation technique. The wireless bridge link controller is connected to the port to exchange physical layer information with said port. When the port detects a change of its PHY mode, it sets the path cost of the link to a value configured for the new PHY mode and forces the bridge to recalculate its spanning tree. The wireless bridge link controller is also connected to the spanning tree controller. If the bridge detects that it has not received BPDUs for a certain time period and the timer will expire soon, the bridge forces the port, via the wireless bridge link controller, to use a more robust PHY mode.
