37、aviour 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 simulate valid and invalid behaviours,

38、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 corresponding abstract protocol tester nee

39、ds to use lower layers to establish a proper connection to the system under test (SUT) over a physical link (Lower layers link). Figure 1: Generic abstract protocol tester The “Protocol Data Units“ (PDUs) are the messages exchanged between the IUT and the abstract protocol tester which permits to tr

40、igger 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, for instance to simulate a primitive from the upper layer or the management/security entity. Further details on such contr

41、ol actions are provided by means of an upper tester presented in clause 4.3. The above “Abstract Test Method“ (ATM) is well defined in ISO/IEC 9646-1 2 and supports a wide range of approaches for testing including the TTCN-3 abstract test language 7. The abstract protocol tester used for MAP-E test

42、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 and FTP, in order to analyse MAP-E functionality. ETSI ETSI TS 103 239-3 V1.1.1 (2014-12)9NOTE: * Those protocols are used to prove certain MAP-E functionalities.

43、Figure 2: Abstract Protocol Tester - MAP-E 4.2 Test configurations The test suite for MAP-E uses two test configurations in order to cover the different test scenarios. Distinction between the two configurations is given by the two main components in MAP-E, which are BR and CPE. 4.2.1 CF01: BR as IU

44、T In this configuration, the BR is the IUT and the test system simulates an CPE in one side and a IPv4 host in the other side.

46、is the IUT 4.3 TTCN-3 Test architecture In general, a conformance test system architecture based on TTCN-3 is as figure 5 shows. Figure 5: Global test architecture The “System Under Test“ (SUT) contains: The “Implementation Under Test“ (IUT), i.e. the object of the test. The “Upper tester applicatio

47、n“ enables to trigger or capture some actions (i.e. higher layer service primitives) on the IUT. The “MAP-E lower layers“ enable to establish a proper connection to the system under test (SUT) over a physical link (Lower layer transport link).

49、4-12)11 The “Upper tester transport“ is a functionality, which enables the test system to communicate with the upper tester application. Then the upper tester can be controlled by a TTCN-3 test component as part of the test process. The “MAP-E test system“ contains: The “TTCN-3 test components“ are processes providing the test behaviour. The test behaviour may be provided as one single process or may require several independent processes. The “Codec“ is a functional part of the test system to encode and d
