Method for processing messages in a communication network comprising a plurality of network nodes

摘要

A method for processing messages in a communication network, wherein messages are transmitted between network nodes of the communication network, which are each combined with test information that is verifiable to determine whether a corresponding message is admissible, where an admissible message leads to a positive test result and an inadmissible message leads to a negative test result. For at least one message that is provided for a respective network node, an action coupled to the message is performed from the respective network node in time a message is received in the respective network node without checking the test information combined with the message, wherein, upon execution of the action, the test information is verified by the respective network node and, when the test result is negative, at least one predefined measure is performed.

1. A method for processing messages in a communication network of an automation system comprising a plurality of network nodes, the method comprising the steps of:
transmitting messages between network nodes of the plurality of network nodes of the communication network of the automation system which are each combined with test information which is verifiable to determine whether a corresponding message is admissible, an admissible message leading to a positive test result and an inadmissible message leading to a negative test result; and performing an action coupled to the message without verification of the test information from the respective network node that is combined with the message for at least one message out of a quantity of messages which are provided for a respective network node of the plurality of network nodes, of at least a portion of the plurality of network nodes, in each case when a message is received in the respective network node of the plurality of network nodes, the test information being verified by the respective network node of the plurality of network nodes upon execution of the action and at least one predefined measure is performed when the test result is negative.
