37、n figure 1 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 syste

38、m will simulate 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,

39、the corresponding 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).

40、ter The “Protocol 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

41、 the SUT, for 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. The above “Abstract Test Method“ (ATM) is well defined in ISO/IEC 9646-1 3 and supports a w

42、ide range of approaches for testing including the TTCN-3 abstract test language 8.The abstract protocol tester used for 6rd 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 and FTP, in order to analyse 6rd f

44、6rd 4.2 Test configurations The test suite for 6rd uses two test configurations to cover the different test scenarios. Distinction between the two configurations is given by the two main components in 6rd, which are the Customer Edge router (CE), also referred to as a Customer Premises Equipment (CP

45、E) and Border Relay router (BR). 4.2.1 CF01: CPE as IUT In this configuration, the CPE is the IUT and the test system simulates a 6rd BR in one side and a IPv6 host in the other side.

ETSI ETSI TS 103 243-3 V1.1.1 (2014-12)11 The “6rd lower layers“ enable to establish a proper connection to the system under test (SUT) over a physical link (Lower layer transport link). 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 “6rd test system“ contains: The “TTCN-3 test components“ are processes
