History Edition Recommendation Approval Study Group 1.0 ITU-T A Suppl. 3 2001-11-30 TSAG 2.0 ITU-T A Suppl. 3 2012-07-04 TSAG ii ITU-T A series Supplement 3 (07/2012) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommu
4、nications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommuni
5、cations on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedu
6、re laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.

14、 the understanding of collaboration on standards development between the Telecommunication Standardization Sector of the International Telecommunication Union (ITU-T) and the Internet Engineering Task Force (IETF) of the Internet Society (ISOC). Early identification of topics of mutual interest will
15、 allow for constructive efforts between the two organizations based on mutual respect. In the IETF, work is done in working groups (WGs), mostly through open, public mailing lists rather than face-to-face meetings. WGs are organized into areas, each area being managed by two co-area directors. Colle
16、ctively, the area directors comprise the Internet Engineering Steering Group (IESG). In the ITU-T, work is defined by study Questions which are worked on mostly through meetings led by rapporteurs (these are sometimes called “rapporteurs group“ meetings). Questions are generally grouped within worki
17、ng parties (WPs) led by a WP chairman. Working parties report to a parent study group (SG) led by an SG chairman. Work may also be conducted in ITU-T focus groups (see clause 2.7). To foster ongoing communication between the ITU-T and IETF, it is important to identify and establish contact points wi
18、thin each organization. Contact points may include: 1. ITU-T study group chairman and IETF area director An IETF area director is the individual responsible for overseeing a major focus of activity with a scope similar to that of an ITU-T study group chairman. These positions are both relatively lon
19、g-term (of several years) and offer the stability of contact points between the two organizations for a given topic. 2. ITU-T rapporteur and IETF working group chair An IETF working group chair is an individual who is assigned to lead the work on a specific task within one particular area with a sco
20、pe similar to that of an ITU-T rapporteur. These positions are working positions (of a year or more) that typically end when the work on a specific topic ends. Collaboration here is very beneficial to ensure the actual work gets done. 3. Other contact points It may be beneficial to establish additio
21、nal contact points for specific topics of mutual interest. These contact points should be established early in the work effort, and in some cases the contact point identified by each organization may be the same individual. ITU-T has an additional level of management, the working party chairman. Fro
22、m time to time, it may be beneficial for this person to exchange views with IETF working group chairs and area directors. NOTE - The current list of IETF area directors and working group chairs can be found in the IETF working group charters. The current ITU-T study group chairmen and rapporteurs ar
23、e listed on the ITU-T study group web pages. 2 ITU-T A series Supplement 3 (07/2012) 2 Guidance on collaboration This clause describes how the existing processes within the IETF and ITU-T may be utilized to enable collaboration between the organizations. 2.1 How to interact on ITU-T or IETF work ite
24、ms Study groups that have identified work topics that are related to the Internet protocol (IP) should evaluate the relationship with topics defined in the IETF. Current IETF working groups and their charters (IETF definition of the scope of work) are listed in the IETF archives (see clause 2.8.1).
25、A study group may decide that development of a Recommendation on a particular topic may benefit from collaboration with the IETF. The study group should identify this collaboration in its work plan (specifically in that of each Question involved), describing the goal of the collaboration and its exp
26、ected outcome. An IETF working group should also evaluate and identify areas of relationship with the ITU-T and document the collaboration with the ITU-T study group in its charter. The following clauses outline a process that can be used to enable each group to be informed about the others new work
27、 items. 2.1.1 How the ITU-T is informed about existing IETF work items The responsibility is on individual study groups to review the current IETF working groups to determine if there are any topics of mutual interest. Working group charters and active Internet-Drafts can be found on the IETF web si
28、te (http:/datatracker.ietf.org/wg/). If a study group identifies a common area of work, the study group leadership should contact both the IETF working group chair and the area director(s) responsible. This may be accompanied by a formal liaison statement (see clause 2.3). 2.1.2 How the IETF is info
29、rmed about existing ITU-T work items The IETF through its representatives will review the current work of the various study groups from time to time. Each ITU-T study groups web page on the ITU-T web site contains its current list of Questions as well as its current work programme. When an area or w
30、orking group identifies a common area of work, the matter is referred to appropriate working group chairs and area directors, where they may consider sending a liaison statement to the appropriate study group. 2.1.3 How the ITU-T is informed about proposed new IETF work items The IETF maintains a ma
31、iling list for the distribution of proposed new work items among standards development organizations. Many such items can be identified in proposed birds-of-a-feather (BoF) sessions, as well as draft charters for working groups. The IETF forwards all such draft charters for all new and revised worki
32、ng groups and BoF session announcements to the IETF new-work mailing list. An ITU-T mailing list is subscribed to this list. Leadership of study groups may subscribe to this ITU-T mailing list, which is maintained by the Telecommunication Standardization Bureau (TSB). Members of the SG-specific list
33、name may include the SG chairman, SG vice-chairmen, working party chairmen, concerned rapporteurs, other experts designated by the SG and the SG Counsellor. This will enable the SGs to monitor the new work items for possible overlap or interest to their study group. It is expected that this mailing
34、list will see a few messages per month. Each SG chairman, or designated representative, may provide comments on these charters by responding to the IESG mailing list at iesgietf.org clearly indicating their ITU-T position and the nature of their concern. Plain-text email is preferred on the IESG mai
35、ling list. It should be noted that the IETF turnaround time for new working group charters can be as short as two weeks. As a result, the mailing list should be consistently monitored. ITU-T A series Supplement 3 (07/2012) 3 2.1.4 How the IETF is informed about ITU-T work items The ITU-T accepts new
36、 areas of work through the creation or update of Questions and these can be found on the ITU-T study group web pages. In addition, the ITU-T work programme is documented on each ITU-T study groups web page on the ITU-T web site. Study groups send updates to the IETF new-work mailing list as new Ques
37、tions are first drafted or created, terms of reference for Questions are first drafted or updated, or otherwise when there is reason to believe that a particular effort might be of interest to the IETF. Area directors or WG chairs should provide comments through liaison statements or direct email to
38、 the relevant SG chairman in cases of possible overlap or interest. 2.2 Representation ISOC, including its standards body IETF, is a Sector Member of the ITU-T. As a result, ISOC delegates are afforded the same rights as other ITU-T Sector Members (see clause 2.2.1). Conversely, ITU-T delegates may
39、participate in the work of the IETF as representatives of the ITU-T (see clause 2.2.2). To promote collaboration, it is useful to facilitate communication between the organizations as further described below. 2.2.1 IETF recognition at ITU-T Experts and representatives from the IETF that are chosen b
40、y IETF leadership normally participate in ITU-T meetings as ISOC delegates. The ISOC focal point will facilitate registration and verification of these people, as appropriate. 2.2.2 ITU-T recognition at ISOC/IETF ITU-T study group chairmen can authorize one or more members to attend an IETF meeting
41、as an official ITU-T delegate speaking authoritatively on behalf of the activities of the study group (or a particular rapporteur group). The study group chairman sends the ITU-T list of delegates by email to the working group chair, with a copy to the area directors, and also to the study group. Ac
42、cording to IETF process, opinions expressed by any such delegate are given equal weight with opinions expressed by any other working group participant. 2.3 Communication outside of meetings Informal communication between contact points and experts of both organizations is encouraged. However, formal
43、 communication from an ITU-T study group, working party or rapporteur group to an associated IETF contact point must be explicitly approved and identified as coming from the study group, working party, or rapporteur group, respectively. Formal liaison statements from the ITU-T to the IETF are transm
44、itted according to the procedures described in RFC 4053 2. These liaison statements are placed by the IETF onto a liaison statements web page at https:/datatracker.ietf.org/liaison/. An individual at the IETF is assigned responsibility for dealing with each liaison statement that is received. The na
45、me and contact information of the responsible person and any applicable deadline is listed with the links to the liaison statement on this web page. Formal liaison statements from the Internet Architecture Board (IAB), the IESG, the IETF, an IETF working group or area to the ITU-T are generated, app
46、roved, and transmitted according to the procedures described in RFC 4053 2 and Recommendation ITU-T A.1 15. Formal communication is intended to allow the sharing of positions between the IETF and the ITU-T outside of actual documents (as described in clause 2.5.1). This covers such things as comment
47、s on documents and requests for input. 4 ITU-T A series Supplement 3 (07/2012) 2.4 Mailing lists All IETF working groups and all ITU-T study group Questions have associated mailing lists. In the IETF, the mailing list is the primary vehicle for discussion and decision-making. It is recommended that
48、the ITU-T experts interested in particular IETF working group topics subscribe to and participate in these lists. IETF WG mailing lists are open to all subscribers. The IETF working group mailing list subscription and archive information are noted in each working groups charter. In the ITU-T, the TS
49、B has set up formal mailing lists for Questions, working parties, and other topics within study groups (more detail can be found on the ITU-T web site). These mailing lists are typically used for ITU-T correspondence, including technical discussion, meeting logistics, reports, etc. NOTE Individual subscribers to this list must be affiliated with an ITU-T member or associate (at this time, there is no blanket inclusion of all IETF participants as members, however, as a member, the ISOC focal point can facilitate access by IETF technical experts, l
