22、specific cable industry requirements as defined in ETSI TS 101 569-1 10 in compliance with the relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 6. The objective of the present document is to provide a basis for conformance tests for 464XLAT technology equipm
23、ent giving a high probability of inter-operability between different manufacturers equipment. The ISO standards for the methodology of conformance testing (ISO/IEC 9646-1 3 and ISO/IEC 9646-2 4) as well as the ETSI rules for conformance testing (ETSI ETS 300 406 7) are used as a basis for the test m

38、is a process providing the test behaviour for testing an IUT. Thus it will emulate an entity which is capable of proving the IUT functionalities. This type of test architecture provides a situation of communication which is equivalent to real operation between real devices. The test system will simu
39、late valid and invalid behaviours, and will analyse the reaction of the IUT. Then the test verdict, e.g. pass or fail, will depend on the result of this analysis. Thus this type of test architecture enables to focus the test objective on the IUT behaviour only. In order to access an IUT, the corresp
40、onding abstract protocol tester needs to use lower layers to establish a proper connection to the system under test (SUT) over a physical link (Lower layers link). SUTTest systemLower layersAbstract protocol testerLower layersIUTLower layers linkPDUsFigure 1: Generic abstract protocol tester The “Pr
41、otocol Data Units“ (PDUs) are the messages exchanged between the IUT and the abstract protocol tester which permits to trigger the IUT and to analyse its reaction. The result of the analysis allows to assign the test verdict. Further control actions on the IUT may be necessary from inside the SUT, f
42、or instance to simulate a primitive from the upper layer or the management/security entity. Further details on such control actions are provided by means of an upper tester presented in clause 4.3. ETSI ETSI TS 103 242-3 V1.1.1 (2014-12)9The above “Abstract Test Method“ (ATM) is well defined in ISO/
43、IEC 9646-1 3 and supports a wide range of approaches for testing including the TTCN-3 abstract test language 8.The abstract protocol tester used for 464XLAT test suite is described in figure 2. The test system will send and receive IP packets, by using other upper layer protocols such as DHCP, DNS a
44、nd FTP, in order to analyse 464XLAT functionality.
