Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Integrated broadband cable telecommunication networks (CABLE). The present doc
4、ument produced for the transition technologies accommodates an urgent need in the industry to define requirements that enable seamless transition of Cable Networks to IPv6. Considering the depletion of IPv4 addresses, transition to IPv6 is required in order to enable continued growth of the customer
5、 base connected to Cable Networks and ensure service continuity for existing and new customers. High-quality connectivity to all kinds of IP-based services and networks is essential in todays business and private life. A plethora of transition technologies have been proposed in IETF, other standardi
6、zation organizations and by manufacturers of IP technology to allow coexistence of IPv4 and IPv6 hosts, access and core networks as well as services. Each of these technology options is specified, implemented and deployed in various forms and stages. The present document is based on the requirements
7、 of ETSI TS 101 569-1 1. The present document is part 2 of a multi-part deliverable covering the conformance tests specification for 6rd technology.

The fields of this proforma as used in the present document are explained in table 2. Table 2: TP proforma field description TP Header
18、TP ID The TP ID is a unique identifier according to the TP naming conventions in table 1 Test objective Short description of test purpose objective according to the requirements from the base standard. Reference The reference indicates the clauses of the reference standard specifications in which th
19、e conformance requirement is expressed. PICS selection Reference to the PICS statement involved for selection of the TP. Contains a Boolean expression. May contain PICS acronyms specified in table. This section is only used in case an optional or conditional behaviour needs to be selected. Mandatory
20、 behaviour is not identified here. TP Behaviour Initial conditions (optional) The initial conditions define in which initial state the IUT has to be to apply the actual TP. In the corresponding “Test Case“ (TC), when the execution of the initial condition does not succeed, it leads to the assignment
21、 of an Inconclusive verdict. Expected behaviour (TP body) Definition of the events, which are parts of the TP objective, and the IUT are expected to perform in order to conform to the base specification. In the corresponding TC,“ Pass“ or “Fail“ verdicts can be assigned there. 5.1 TPs for CPE 5.1.1
