1. An apparatus for analyzing a data packet, the apparatus comprising:
- a deriving unit configured to access data of the data packet and output first and second information relating to the data packet,a calculating unit configured to, on the basis of the first information, select one of a plurality of predetermined functions, and derive third information by applying the selected function to the second information, andan output element configured to output the third information together with at least part of the data packet,wherein the deriving unit is configured to output the first information relating to a type of the data packet, a standard to which the data packet conforms and/or which data item(s) is/are present in the data packet,the apparatus further comprising a plurality of outputs, wherein the output element is configured to, for a data packet, identify an output on the basis of the third information relating to the data packet and output the third information relating to the data packet and the at least part of the data packet on the identified output.

Abstract
An apparatus and method for analyzing a data packet, where the first and second information is derived relating to the data packet. The first information relates to a type of the data packet, a standard to which the data packet conforms and/or which data item(s) is/are present in the data packet. The first information is used for identifying a function into which the second information is input to generate third, and this third information is output together with at least part of the data packet.

8. A method of analyzing a data packet, the method comprising:
-
deriving and outputting, from the data packet, first and second information relating to the data packet, selecting, on the basis of the first information, one of a plurality of predetermined functions, deriving third information by applying the selected function to the second information, and outputting the third information together with at least part of the data packet, wherein the first information relates to a type of the data packet, a standard to which the data packet conforms and/or which data item(s) is/are present in the data packet, and wherein the outputting step comprises, for a data packet, identifying one of a plurality of outputs on the basis of the third information relating to the data packet and outputting the third information relating to the data packet and the at least part of the data packet to the identified output. - View Dependent Claims (9, 10, 11, 12, 13, 14)
