Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Integrated broadband cable
telecommunication networks (CABLE).
The present document 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 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 today's business and private life.
A plethora of transition technologies have been proposed in IETF, other standardization 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 of ETSI TS 101 569-1 [1].
The present document is part 2 of a multi-part deliverable covering the conformance test specification for DS-Lite
technology.
Part 1: "Protocol Implementation Conformance Statement (PICS) proforma";
Part 2: "Test Suite Structure and Test Purposes (TSS&TP)";
Part 3: "Abstract Test Suite (ATS) and Protocol Implementation eXtra Information for Testing (PIXIT)".
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "may not", "need", "need not", "will",
"will not", "can" and "cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms
for the expression of provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.

1 Scope
The present document provides the Test Suite Structure and Test Purposes (TSS&TP) descriptions for the IPv6
transition technology DS-Lite to validate its implementation within a cable communications networks.
The tests are in reference to [1], the ETSI specifications for IPv6 transition technology.
The ISO standards for the methodology of conformance testing (ISO/IEC 9646-1 [2] and ISO/IEC 9646-2 [3]) as well
as the ETSI rules for conformance testing (ETSI ETS 300 406 [4]) are used as a basis for the test methodology.

5 Test purposes
This clause proposes a TP proforma which is used in the present document. The fields of this proforma as used in the
present document are explained in table 2.
Table 2: TP proforma field description
TP Header
TP ID The TP ID is a unique identifier according to the TP naming convention 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 the
conformance requirement is expressed.
TP Behaviour
Initial conditions The initial conditions define in which initial state the IUT has to be to apply the actual TP.
(optional) In the corresponding "Test Case" (TC), when the execution of the initial condition does
not succeed, it leads to the assignment of an Inconclusive verdict.
Expected behaviour Definition of the events, which are parts of the TP objective, and the IUT are expected to
(TP body) perform in order to conform to the base specification. In the c
