Methods for the configuration of a device in a data network are provided. According to one method, a domain name is first stored in the device. The device then transfers an inquiry message comprising the domain name to an addressing server that serves for the conversion between the domain name and the associated internet addresses. In a further step, the addressing server transmits an address information of a parameter server associated with said device to the device as a response to said inquiry message. The device establishes a link to the parameter server on the basis of said address information. The parameter server transmits via this link parameters to the device which serve to configure the device.

Method and arrangement for configuring a device in a data network

According to the invention, an availability request is transmitted by a client to a server in order to verify whether a server is available. A response to said availability request is transmitted by the server to the client by means of a confirmation message if the server is available. The client transmits a message regarding the availability of the server to other clients who then prevent the transmission of an availability request to the server at least for a predefined period of time.

Verification of the availability of a server

To assign clients distributed across a plurality of subnetworks to a server, one of the clients is first selected in a respective subnetwork. A search is carried out across the subnetworks by a respective selected client for other selected clients and for the server, whereby when it locates the server, the selected client stores server address information identifying said server and when it locates another selected client, it requests the server address information from that client and stores it on receipt. The stored server address information is transmitted by the selected client to one or a plurality of other selected or non-selected clients.

Method for assigning clients distributed across a plurality of networks to a server and a client for implementing the method

In a system having distributed components arranged in a logical ring structure, each component monitors only their respective neighboring component in the structure and the condition of the neighboring component is determined. If a component determines a condition of its neighboring component that corresponds to a predefinable condition, the component informs the other components of the system of the predefined condition of the neighboring component.

The invention relates to a method and an arrangement for the configuration of a device in a data network. According to said method, a domain name is first stored in the device. The device then transfers an inquiry message comprising the domain name to an addressing server that serves for the conversion between the domain name and the associated internet addresses. In a further step, the addressing server transmits an address information of a parameter server associated with said device to the device as a response to said inquiry message. The device establishes a link to the parameter server on the basis of said address information. The parameter server transmits via this link parameters to the device which serve to configure the device.

For alternate operation of a terminal (EG) at at least two communication nodes (GK, GK), the terminal (EG) is first registered with a first of the communication nodes (GK). In this case, registration is followed by there being a logical connection between the terminal (EG) and the first communication node (GK). The obtainability of the first communication node (GK) is monitored, and in the event of the first communication node (GK) being unobtainable a status information item relating to the unobtainability is produced, and the status information item is taken as a basis for setting up a logical connection between the terminal (EG) and the second communication node (GK). The terminal (EG) is then automatically operated at the second communication node (GK).

Method and communication arrangement for alternately operating a terminal at at least two communication nodes

In order to configure a device (EG) in a data network (LAN), an address for an address assignment server (DHCP) is first of all stored in the device (EG). The device (EG) then transmits an inquiry message, which includes a distinguishing data record, to an address assignment server (DHCP). In a further step, as the response to the inquiry message, the address assignment server (DHCP) transmits address information for a parameter server (ADS) associated with the device (EG) to this device (EG), and this address information is stored in a freely useable data field. The device (EG) then uses the address information to produce a connection to the parameter server (ADS). The parameter server (ADS) uses this connection to transmit to the device (EG) parameters which are used for configuration of the device (EG).

Method and arrangement for configuration of a device in a data network

In order to operate a communication terminal for packet-oriented data transmission, at least one piece of status information is stored, for a communication terminal, in a memory unit associated with the communication terminal. Said status information is provided with a digital signature that is calculated from the status information by means of a private key for an asymmetrical encoding method associated with a first control unit associated with the communication terminal, for the resolution and/or conversion of network addresses. If the first control unit fails, a request is transmitted comprising the status information and the digital signature to associate the communication terminal with at least one second control unit, and the digital signature is checked. In the event of a positive check result, the communication terminal is associated with the second control unit.
