13、ods for Testing and Specification (MTS). Introduction IPv6 is the next generation Internet. It gives vastly increased address space and true end-to-end communication. It has improved security and mobility features and allows “plug-and-play“ connection to the network. The complexity of implementing I

14、Pv6 technology and the relative openness of IETF standards means that wide-ranging and effective testing of IPv6 products will be one of the key factors in ensuring the deployment, interoperability, security and reliability of the IPv6 infrastructure. The present document specifies interoperability

15、tests for IPv6 Mobility. The test suite results from and analysis of RFC 3775 and RFC 3776, the extraction of the requirements contained in these documents, and a selection of the requirements which could be tested by interoperability means. The methodology and framework used to analyse the RFCs, to

16、 extract the requirements, write the Test Purposes, and the test descriptions is described in TS 102 351 1. The reader is strongly encouraged to read TS 102 351 1 in order to make the best usage of the present document. ETSI ETSI TS 102 598 V1.1.1 (2007-06) 5 1 Scope The present document specifies t

17、he interoperability Test Descriptions (TDs) with integrated Test Purposes (TPs) for the IPv6 Mobility standards. The TDs are presented in the tabular form specified in TS 102 424 (see Bibliography) and the TPs are defined using the TPLan notation also described in ES 202 553 (see Bibliography). 2 Re
