Foreword This Technical Specifi
14、cation (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
15、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 netw
16、orks is essential in todays 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
17、technology options is specified, implemented and deployed in various forms and stages. The present document is based on the requirements ETSI TS 101 569-1 1. The present document is part 1 of a multi-part deliverable covering the conformance test specification for DS-Lite technology. Part 1: “Protoc

ETSI ETSI TS 103 241-1 V1.1.1 (2015-01)51 Scope The present document provides the Protocol Implementation Conformance Statement (PICS) proforma for conformance test specifications for the IPv6 transition technology DS-Lite as defined in ETSI TS 101 569-1 1 in compliance with the relevant requi
21、rements and in accordance with the relevant guidance given in ISO/IEC 9646-7 3. A supplier of an implementation which is claimed to conform to ETSI TS 101 569-1 1 is required to complete a copy of the PICS proforma provided in the annex A of present document. 2 References 2.1 Normative references Re

29、46-1 2 and ISO/IEC 9646-7 3 apply. In particular, the following terms given in ISO/IEC 9646-1 2 apply: Implementation Conformance Statement (ICS): statement made by the supplier of an implementation or system claimed to conform to a given specification, stating which capabilities have been implement
30、ed. The ICS can take several forms: protocol ICS, profile ICS, profile specific ICS, information object ICS, etc. ICS proforma: document, in the form of a questionnaire, which when completed for an implementation or system becomes an ICS Protocol ICS (PICS): ICS for an implementation or system claim

34、PICS proforma to be filled in by a supplier shall be technically equivalent to the text of the PICS proforma given in annex A, and shall preserve the numbering/naming and ordering of the proforma items. A PICS which conforms to the present document shall be a conforming PICS proforma completed in ac
35、cordance with the instructions for completion given in clause A.1. ETSI ETSI TS 103 241-1 V1.1.1 (2015-01)7Annex A (normative): DS-LITE PICS Proforma Notwithstanding the provisions of the copyright clause related to the text of the present document, ETSI grants that users of the present document may
36、 freely reproduce the DS-LITE PICS proforma in this annex so that it can be used for its intended purposes and may further publish the completed DS-LITE PICS. A.1 Guidance for completing the PICS proforma A.1.1 Purposes and structure The purpose of this PICS proforma is to provide a mechanism whereb
37、y a supplier of an implementation of the requirements defined in ETSI TS 101 569-1 1 may provide information about the implementation in a standardized manner. The PICS proforma is subdivided into clauses for the following categories of information: - guidance for completing the PICS proforma; - ide
38、ntification of the implementation; - identification of the ETSI TS 101 569-1 1; - global statement of conformance; - PICS proforma tables. A.1.2 Abbreviations and conventions The PICS proforma contained in this annex is comprised of information in tabular form in accordance with the guidelines prese
39、nted in ISO/IEC 9646-7 3. Item column The item column contains a number which identifies the item in the table. Item description column The item description column describes in free text each respective item (e.g. parameters, timers, etc.). It implicitly means “is supported by the implementation?“.
40、Status column The following notations, defined in ISO/IEC 9646-7 3, are used for the status column: m mandatory - the capability is required to be supported. o optional - the capability may be supported or not. n/a not applicable - in the given context, it is impossible to use the capability. x proh
41、ibited (excluded) - there is a requirement not to use this capability in the given context. o.i qualified optional - for mutually exclusive or selectable options from a set. “i“ is an integer which identifies an unique group of related optional items and the logic of their selection which is defined
42、 immediately following the table. ETSI ETSI TS 103 241-1 V1.1.1 (2015-01)8ci conditional - the requirement on the capability (“m“, “o“, “x“ or “n/a“) depends on the support of other optional or conditional items. “i“ is an integer identifying an unique conditional status expression which is defined
43、immediately following the table. i irrelevant (out-of-scope) - capability outside the scope of the reference specification. No answer is requested from the supplier. NOTE 1: This use of “i“ status is not to be confused with the suffix “i“ to the “o“ and “c“ statuses above. Reference column The refer
44、ence column makes reference to ETSI TS 101 569-1 1 V1.1.1 (2013-10) except where explicitly stated otherwise. Support column The support column shall be filled in by the supplier of the implementation. The following common notations, defined in ISO/IEC 9646-7 3, are used for the support column: Y or
45、 y supported by the implementation. N or n not supported by the implementation. N/A, n/a or - no answer required (allowed only if the status is n/a, directly or after evaluation of a conditional status). NOTE 2: As stated in ISO/IEC 9646-7 3, support for a received PDU requires the ability to parse
46、all valid parameters of that PDU. Supporting a PDU while having no ability to parse a valid parameter is non-conformant. Support for a parameter on a PDU means that the semantics of that parameter are supported. Values allowed column The values allowed column contains the type, the list, the range,
47、or the length of values allowed. The following notations are used: - range of values: example: 5 20 - list of values: , , ., example: 2, 4, 6, 8, 9 example: 1101B, 1011B, 1111B example: 0AH, 34H, 2FH - list of named values: (), (), ., () example: reject(1), accept(2) - length: size ( ) example: size
48、 (1 8) Values supported column The values supported column shall be filled in by the supplier of the implementation. In this column, the values or the ranges of values supported by the implementation shall be indicated. References to items For each possible item answer (answer in the support column)
49、 within the PICS proforma a unique reference exists, used, for example, in the conditional expressions. It is defined as the table identifier, followed by a solidus character “/“, followed by the item number in the table. If there is more than one support column in a table, the columns are discriminated by letters (a, b, etc.), respectively. EXAMPLE: 5/1 is the reference to the answer of item 1 in table A.5 of annex A. ETSI ETSI TS 103 241-1 V1.1.1 (2015-01)9Prerequisite line A prerequisite line takes the form: Prerequi
