Method for filtering and processing data in a packet-switched communication network

A packet-switched communication network, comprising:

• a plurality of network nodes between which data packets are transmitted while the packet-switched communication network is operating, with the packet-switched communication network programmed to perform a method for processing data in the packet-switched communication network, which method comprises the steps of:
• extracting, at least partially, information contained in the data packets received in the network nodes;
• ascertaining physical transmission parameters of the data packets, the physical transmission parameters specifying or being dependent on at least one characteristic of a physical transmission of the data packets;
• filtering the data packets on a basis of a set of rules that take at least a part of the information extracted and at least a part of the physical transmission parameters into account and processed further in dependence on a filtering process;
• and
• wherein the data packets received in the network nodes include configuration-data packets transmitted within a scope of a predefined configuration process, with the network nodes being configured through the predefined configuration process, with a measure of confidence therein being ascertained on a basis of the at least one physical transmission parameter of the configuration-data packets received, the measure of confidence indicating a confidence that the configuration-data packets received belong to the predefined configuration process, with the predefined configuration process being canceled or interrupted if the measure of confidence represents a degree of confidence that is less than or less than or equal to a predefined minimum confidence.

A network node for use in a communication network, the network node comprising:

• a radio receiver;
• a filter connected to said radio receiver;
• a processing unit connected to said filter;
• the network node programmed to:
• extract information contained in data packets received in the network node in the communication network from the data packets while the network node is operating;
• ascertain at least one physical transmission parameter of the data packets while the network node is operating, with the physical transmission parameter specifying or being dependent on at least one characteristics of a physical transmission of the data packets;
• filter the data packets on a basis of a set of rules taking account of at least a part of the information extracted and at least a part of the physical transmission parameter while the network node is operating and processed further in dependence on a filtering process;
• and
• wherein the data packets received in the network node include configuration-data packets transmitted within a scope of a predefined configuration process, with the network node being configured through the predefined configuration process, with a measure of confidence therein being ascertained on a basis of the at least one physical transmission parameter of the configuration-data packets received, the measure of confidence indicating a confidence that the configuration-data packets received belong to the predefined configuration process, with the predefined configuration process being canceled or interrupted if the measure of confidence represents a degree of confidence that is less than or less than or equal to a predefined minimum confidence.
