WGN AMSG 02 (New Orleans)

1Introduction

This document reports about the decisions taken by the ATN Maintenance Sub-Group (AMSG) at its 2nd meeting held in New Orleans on the 15th November 2004.

2General Issues

Directory Sub-Volume. There is no acting Subject Matter Expert (SME). As a consequence, the Proposed Defect Reports (PDR)related to the ATN Directory specification (Doc 9705 SV-VII) submitted to AMSG are not actively handled. In addition, no engineering version has been produced to reflect the RESOLVED PDRs. There is an urgent need for appointing a SME for SV-VII.

AMSG mailing lists. As agreed at AMSG-01 (Montreal, May 04), 4 additional mailing lists have been created on the CENA server. As a result, there are 1 general list for amsg and 1 list for each sub-volume. The CCB procedure document has been updated and is available on the CENA server under the "shared web" directory at .

Engineering versions. The Engineering version for SV-I, II, III, IV, VIII and IX are on the CENA server (under amsg "shared web" directories) and are aligned with the PDRs resolved before the AMSG-02 meeting.

4.4Sub-Volume III

-Most of the new PDRs are issued from the FIRST project (DFS/AENA/German AirForce – AMHS implementation and validation), are due to different interpretationsof Annex 10 (AFTN) and Doc 9705 (ATN) and concern the AMHS/AFTN gateway. They address 'tail of the tail' situations.

-5 PDRs for which further work is required have their status unchanged (ACCEPTED).

-7 PDRs progressed to RESOLVED.

-Impact Status was changed for 3 PDRs (interoperability problems or bug)

-1 rumored PDR expected to be produced by NATS.

4.8Sub-Volume VII – ATN Directory

The sub-volume VII as published by ICAO in Edition 3 Doc 9705 is not correct (PDR M4050006). Additional work is needed to retrieve the correct baseline version, if such one still exists. PDR M4110002 addresses an issue which cannot be resolved independently of the work currently performed by SGN/3 on the minimum global AMHS profile. The PDR is therefore FORWARDED to SGN/3. PDR M4110001 asks whether the ATN Directory should be a separate directory or can be integrated in a more global directory. The issue is presented to WG/N.

The feeling of AMSG is that all the PDRs related to Directory need to be worked out by WG/N altogether with the new version of the base specification.

5Recommendations

The WG/N members are invited :

  1. to note the progress of the AMSG on Doc 9705,
  1. ask the ACP Secretary to post the current version of the P/OICS on the ACP web site,
  1. to formally designate a new SME for SV-VII,
  1. to provide advices to AMSG on Directory PDRs (see PDRs attached), and
  1. to explicitly task SGN/3 to work on the ATN Directory and associated PDRs.

Summary of Defect:

The ATN Directory has a single overall Root, and a ‘relative’ root for the AMHS Publication Service. Currently, Doc. 9705 does not state which register of country names (ISO 1366 vs. ICAOState identifiers) are to be used for each case. Also, the precise relationship between the ATN Directory and the Global Directory (if any) is not clear. This paper outlines the possibilities and suggests updates to Doc. 9705 to avoid implementation and configuration ambiguities.

Each entry in a Directory Information Tree must be associated with a registration authority to ensure that its subordinate entries are identified unambiguously. This paper deals with two ‘roots’ that are of importance to AMHS, and also seeks to clarify the relationship between the ATN Directory and the Global Directory.

Relation of ATN Directory to Global Directory:

Doc. 9705 defines an ATN Directory starting at the Root entry, with Country Names as the first level entries under the root. This is identical to the top-level structure of the Global Directory as defined in X.500. Several questions arise:

-- Is it the intention that the ATN Directory should share a common root with the Global Directory?. If so, then this should be stated in Doc. 9705.

-- Is it the intention to maintain a separate ATN Root to that of the Global Root? If so, this should be stated in Doc. 9705.

-- Is it the intention to use the ISO 3166 register of country names as the first level (which potentially allows a shared root with the Global Directory), or is it the intention to use ICAO state names as the register? (in which case any form of interoperability with the Global Directory would probably be impossible). Doc. 9705 should state the outcome of this intention.

Country Name Register for the (AMHS) Address Publishing Service:

The Address Publication Scheme that has been developed for AMHS>AFTN>CIDIN address translation information distribution also has a ‘relative root’ within the main DIT, under which the addressing information for ATSPs is held. There are several questions:

-- At what point in the ATN DIT is this APS Root located (i.e. what is its Directory Name)?

-- What register of country names is to be used to identify the first level entries under this root – the ISO 3166 register (using the X.500 defined Country Name attribute) or the ICAO register of State names (using the atn-icao-country-code attribute)?

Proposed SARPs amendment:

The answers to these questions need to be included in Doc. 9705.
