AMHSAMHS


AMHS is a message handling system that allows Office of Air Traffic Services (ATS) Messages to be exchanged between service users. It based on ISO/IEC 10021 or ITU-T X.400. AMHS message service provides Basic Service and Extended Service

• Basic Service - Based on ISO/IEC 10021: 1990• Extended Service - Based on ISO/IEC 10021: 1999

Extended Service is a superset of Basic Service, support more complex message structures (body parts), use of the directory service, and support security

• ATN SARP compliant MTA and Router states can exchange traffic from their MTA to any MTA

• IP based MTA and Router will require its traffic to be forwarded by ATN SARP compliant MTA

• Discussion:

- Address allocation - IPv4 vs. IPv6 - Documentation
