    摘要： The invention relates to a method for analyzing services (2A, 2B, 2C) of nodes (1A, 1B, 1C) of a network which communicate with each other over the network, wherein the communication of the nodes with each other over the network comprises sending messages from at least one node to at least another node over the network, the method comprising the following method steps:
    a) checking for at least a part of the messages whether a respective message comprises a service information (6) and ignoring a message if the respective message does not comprise a service information (6),
    b) analyzing the service information (6) of messages which comprise a service information (6) by identifying from the service information (6) of a respective message at least one of the following information: the sending node (10), the receiving node (12, 14), the service identification number, the service action (30) between the sending node (10) and the receiving node (12, 14), the status of the communication connection (40) between the sending node (10) and the receiving node (12, 14), and the time to live of the communication connection,
    c) saving the previously identified service information (6) in a plurality of service instance history tables (3), and
    d) visualizing the previously identified service information (6) by a visualization unit (4) on the basis of the plurality of service instance history tables (3). This way a method for analyzing the services in a network is provided that is simpler and less error-prone.

    摘要： The invention relates to a method for monitoring a communication between a first entity (110) and a second entity (130). The method comprises: receiving (210) measurement data indicative of a payload data; receiving (220) metadata from data storage configured to store metadata received prior to the payload data traffic; comparing (230) at least one parameter derivable from the measurement data to respective at least one parameter derivable from the metadata, and setting (240) a detection result to express one of the following: (i) the payload data between the first communicating entity (110) and the second communicating entity (130) complies with the metadata, (ii) the payload data between the first communicating entity (110) and the second communicating entity (130) deviates from the metadata. The invention also relates to a network node (120), to a communication system, and to a computer program.
