20、-04)61 Scope The present document contains the Abstract Test Suite (ATS) for Transmission of IP packets over GeoNetworking as defined in EN 302 636-6-1 1 in compliance with the relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 5. The objective of the present

21、document is to provide a basis for conformance tests for Transmission of IP packets over GeoNetworking equipment giving a high probability of interoperability between different manufacturers equipment. The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 2 and ISO/IEC 9646-2 3

22、) as well as the ETSI rules for conformance testing (ETS 300 406 6) are used as a basis for the test methodology. Annex A provides the Tree and Tabular Combined Notation (TTCN) part of the ATS. Annex B provides the Partial Protocol Implementation Extra Information for Testing (PIXIT) Proforma of the

23、 ATS. Annex C provides the Protocol Conformance Test Report (PCTR) Proforma of the ATS. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

37、 4.2 Test Configuration The IPv6OverGeoNetworking test suite uses a unique test configuration in order to cover the different test scenarios. In this configuration, the tester simulates one ITS station implementing the IPv6OverGeoNetworking protocol. IUTGVL_AREA1GVL_AREA3GVL_AREA2ItsNodeAFigure 2: T

38、est configuration CF01 Both IUT and Test system are located in the GeoAreas associated with the three predefined GVLs. Each GVL is associated with an IPv6 prefix which can be parameterized using module parameters. ETSI ETSI TS 102 859-3 V1.2.1 (2014-04)9Table 1: Association between IPv6 prefixes and

Figure 3 shows the TTCN-3 test architecture used in for the GeoNet

40、working ATS. The IPv6OverGeoNetworking test component requires using only the Main Test Component (MTC). The MTC communicates with the IPv6OverGeoNetworking SUT over the ipv6OverGeoNetworkingPort and geoNetworkingPort. The ipv6OverGeoNetworkingPort port is used to exchange IPv6 protocol messages bet

41、ween the test component and the IUT. The geoNetworkingPort port is used to exchange GeoNetworking protocol messages between the test component and the IUT. The Upper tester entity in the SUT enables triggering IPv6OverGeoNetworking functionalities by simulating primitives from applications. It is re

42、quired to trigger the IPv6OverGeoNetworking layer in the SUT to send IPv6OverGeoNetworking messages, which are resulting from upper layer primitives. Furthermore, receiving IPv6OverGeoNetworking messages may result for the IPv6OverGeoNetworking layer in sending primitives to the upper layer. ITS TTC
