Abstract: The invention relates to a method and a device for the optimized negotiation of communication parameters for a transmission of data in communication links. A list is initialized in a communication initializing device and is sent one after another to all devices involved in the communication during the connection set-up phase. Each of the devices adds its own and most suited transmission parameters to the list. Said parameter list is sent to the communication initializing device by the last device involved in the communication. The initializing communication device finally selects the transmission parameters. The parameter list established in this way is one after another sent to all devices involved in the transmission to inform them on the valid parameter selection. Each device configures its parameter setting for a corresponding connection by means of the received parameter list. Thus, a configuration of the devices involved in the communication is effected for the subsequent data transmission.
