VI.3 Using a formal description technique for the termsABNF is used as an example formal language in this Appendix. VI.3.1 Formal specification of flow descriptor (flow level conditions)Table VI.3.1 provides a formal description of the flow level conditions, which is in line with the prose specification for flow (clause 3.1.3) and flow descriptor/flow level conditions (clause 3.2.16). Table VI.3.1 – Formal specification of flow descriptor (flow level conditions)
VI.3.2 Formal specification of application descriptor (application level conditions)Table VI.3.2 provides a formal description of the application level conditions, which is in line with the prose specification of clause 3.2.2. Table VI.3.2 – Formal specification of application descriptor (application level conditions)
VI.3.3 Formal specification of DPI SignatureTable VI.3.3 provides a formal description for DPI signature, which is in line with the prose specification of clause 3.2.14. Table VI.3.3 – Formal specification of DPI Signature
Appendix VII Illustration of terminology (This appendix does not form an integral part of this Recommendation) VII.1 IntroductionThe main body of the Recommendation defines requirements for DPI. Some of these requirements refer to identification of packets (and aggregates like flow) and indicate possible actions after identification. The terms of filtering, classification, modification, etc. of packets are used in this context. There are commonalities and differences between these terms as used in the scope of this Recommendation. The purpose of this appendix is to illustrate the underlying concept. VII.2 Rule-oriented Packet ProcessingThe consideration of packet inspection as rule-based packet processing allows to depicting the key differences between the used terms. Figure VII.1 shows the generic model, based on the rule definition according clause 3.1.2. 
Figure VII.1 – Generic Model for Rule-oriented Packet Processing The generic model uses a dual-stage server, given by the processing of conditions and actions as principle parts of a rule. Such a separation allows to indicate, e.g., that all basic requirements of DPI share the common characteristic of packet identification. The generic model may be applied on the DPI requirements (as specified in the main body of this Recommendation), see next sub-clause.
