Communication device for token ring communication network, has communication processing module transferring or copying messages, that are not intended for device, between inputs-outputs, and blocking messages that are intended for device

摘要

The device has an application processing module (14) connected to a communication processing module (13) to receive messages from input-outputs of communication, and to transmit messages towards input-outputs of communication. The module (13) transfers or copies messages, which are not intended for the device, between inputs-outputs (11, 12), and blocks the messages which are intended for the device and are supplied to the module (14). Independent claims are also included for the following: (A) a ring communication network including at least three communication devices (B) a communication method for a ring communication network.
