Asia/Pacific ATN Regional Planning

ATN Seminar Chiang Mai, 11th - 14th December 2001

Presented by Craig Head

ATN Transition Task Force

�The ATN Transition Task Force (ATNTTF) was established by APANPIRG/9 (1998) to address ATN Issues and to deal with residual AFS Issues.

�The ATNTTF reports are reviewed by CNS/MET Sub-Group before being submitted to APANPIRG

�The ATNTTF will schedule its fourth meeting in Mumbai in April 2002.

ATNTTF ATN Responsibilities

�The ATNTTF is Responsible for the Development of:

�ATN Transition Guidance Material�ATN Transition Plan�ATN Interface Control Documents�Technical Information on security, performance and

system management issues�Provide Planning and Implementation Information

in the Air Navigation Plan�Develop the ground ground part of the CNS

Facilities And Services Implementation Document (FASID)

ATNTTF Working Groups

�The ATNTTF Established Two Working Groups:

�Working Group A�Development of ATN technical plans

�Working Group B�Development of an ATN transition plan and other

ATN technical documents

ATNTTF Working Group A

�Established to develop the following Plans:�ATN Routing Architecture Plan�ATN NSAP Addressing Plan�AMHS Naming Plan�ATN NSAP Registration Plan

�WG A Includes Representatives from:�Australia�Japan�Thailand�United States

Status of Plans

�Plans submitted for review at the ATNTTF/3 in March 2001.

�Plans were reviewed at CNS/MET Sub Group/5 in July 2001.

�Plans were approved by APANPIRG/12 in August 2001.

�Plans to be circulated to States for comments.

ATN Routing Architecture Plan

�The establishment of Backbone Boundary Intermediate Systems (BBIS)

�Describes the role of a BBIS:�Must be very reliable�Capacity - capable of supporting significantly

more traffic�Alternative Routing - have access to multiple

links�Routing Policies - must support Regional

transit traffic and dynamic re-routing of traffic

AMHS Naming Plan

�Aligned with the Global AMHS Naming Convention to be adopted by ICAO

�ATN Panel Working Groups have recommended that the Global AMHS Naming Convention be included in Edition 3 of the ATN Manual

AMHS Name Assignments

�Proposed to use the following name attributes:�Country Name - XX�ADMD - ICAO�PRMD - States to register preferred name with

ICAO�Organisation Name�Unit Name�Common Name (includes the AFTN

Indicator)

ATN Transition Plan

�Recommends a Three Stage ATN Transition Phase:�Stage 1 - Upgrade Current/Existing

Infrastructure�Stage 2 - Establishment of a Ground ATN

Backbone Router Network�Stage 3 - Connectivity of User ATN Routers to

the Backbone

Existing AFTN Infrastructure

�AFTN Infrastructure�Based on point to point circuits�Majority of Circuits are low speed: 50 baud

through to 9600bps�Circuit Protocols range from no protocols

through to COPB and X.25

Stage 1 - Upgrade of Circuits

�ATN at present requires Subnetworks to interface at X.25

�Currently the majority of AFTN circuits (88%) will not be suitable for ATN

�This will require new circuits to be implemented or existing circuits to be upgraded

Stage 1 - Bandwidth Issues

�Bandwidth for circuits will need to be increased substantially.

�Speeds from 9.6kbps to 64kbps or higher will need to be considered.

�Overheads from each layer of the OSI stack will increase total message size as much as 94% (standard AFTN message size using AMHS)

AMHS ICD - (1)� Development of an Interface Control Document

for interconnection of AMHS in the Asia Pacific Region.

� Document based on the AMHS work performed between Japan and USA.

� Outlines the Mandatory and Optional Requirements described in the AMHS PICS that are to be implemented within the Asia Pacific Region to maintain operability.

� Document will be presented at the Fourth ATNTTF meeting.

AMHS ICD - (2)

�The ICD does not include any additional features such as CIDIN/AMHS Gateway, Security and Directory Service which are in ICAO Doc 9705/AN-965, THIRD EDITION.

� The ICD can be enhanced to include such additional features in the future.

AFTN to AMHS Transition

�ATS Message Handling System will most likely be one of the first ATN Applications to be implemented by most States in the Region.

�Transition to AMHS can involve a number of steps�Introduction of AFTN/AMHS Gateways.�To full AMHS Interconnection between States.

AIDC Implementation

�ATS Inter-facility Data Communication� ATN AIDC is not Compatible with AIDC

over AFTN.�Implementation of ATN AIDC will need to

be implemented by agreement between States.

�Possible phased implementation could be AIDC over AFTN to AIDC/AFTN over AMHS.

Summary

�Implementation of new links or Upgrade existing AFTN links where appropriate to be compatible with ATN protocols.

�Plan for adequate bandwidth which can be increased without restriction.

�Interim arrangements can be set up between States which have already started their implementation programs.
