Ubimex

Ubiquitous message exchange for ATS message centers

Ubimex is IDS’s field tested and proven Air Traffic Service (ATS) Message Handling System (AMHS). While AMHS technology is relatively new to the field of air traffic management, IDS has extensive experience in the underlying X.400 technologies having deployed numerous X.400 message switches around the world. The result of these years of experience is an AMHS system that is both feature-packed and highly reliable.

Ubimex message exchange

Ubimex consists of 5 core components:

  • Message Transfer Agent (ubiMTA): Provides the core message switching and AMHS communications of Ubimex
  • Message Store (ubiMS): A robust database for short and long-term message storage
  • Access Unit (ubiAU): Provides bidirectional protocol/message/address conversion between AMHS and a number of different standards
  • Directory Services (ubiDS): An x.500 directory service that contains information about AMHS entities and makes it available to the AMHS community
  • User Agent (Ubimex Web): A secure web-based portal through which both operator and administrator users can perform all the functions of AMHS

Ubimex Web also provides operators with an integrated environment for AMHS and AFTN messaging modeled after popular email applications such as Microsoft’s Outlook Web Client and Google’s Gmail. In addition, it allows system administrators to configure, maintain and monitor AMHS operations using a graphical user interface.

Applications

message exchange
for ATS message centers

Ubimex - Main Applications

ICAO introduced AMHS (or ATSMHS – Air Traffic Service Message Handling System) in the early 2000s to replace the aging and limited AFTN technology previously in use. AMHS allows data such as flight plans, meteorological data and NOTAMs to be transmitted at high data rates between ground-ground users, primarily Air Navigation Service Providers (ANSPs) but also airports, air forces and meteorological services.

Ubimex consists of 5 core components:

ubiMTA provides the core message switching and AMHS communications of Ubimex:
  • Dual-Stack [OSI & IPS]
  • 400 P1 communications with adjacent MTAs
  • Delivery/Reception to/from the message store
  • Routing of messages, probes and reports
  • Automatic generation of reports
  • Validation and authentication of originator & recipients
  • Detailed transaction and event logging
  • High message throughput with low latency
  • Support for binary message attachments
  • Optional security using x.509 Public Key Infrastructure
ubiMS is a robust database for short & long-term message storage:
  • Receives messages from ubiMTA on behalf of users [Inbox]
  • Submits messages to ubiMTA on behalf of users [Outbox]
  • Keeps all message traffic for a user-configured duration
  • Provides high-performance message searches
  • Simple tools for backup and archival
ubiAU [also known as an AMHS/AFTN Gateway] provides bidirectional protocol/message/address conversion between AMHS [x.400] and the following:
  • AFTN
  • NADIN [I, II, IP]
  • CIDIN
  • SITA
  • Email
  • WMO
  • Fax
ubiDS is an x.500 directory service that contains information about AMHS entities and makes it available to the AMHS community:
  • Supports LDAP, DAP, & DSP protocols
  • Provides directory lookup for users
  • Serves as the validation source for message addressing
  • Optionally can store the end user x.509 certificate
Ubimex Web User Agent is a secure web-based portal through which both operator and administrator users can perform all the functions of AMHS:
  • Operator, Supervisor, Reject, & Intercept Messaging
  • AMHS/AFTN Gateway [ubiAU] Control Position
  • System Configuration, Maintenance, & Monitoring
  • Directory User Agent
Ubimex Web offers operators an integrated environment for AMHS and AFTN messaging modeled after popular email applications such as Microsoft’s Outlook Web Client and Google’s Gmail:
  • View message traffic easily using Personal or Group Inboxes, Outboxes, & Sent Items
  • Ease the transition to AMHS by choosing to create messages using AMHS or AFTN views
  • Simplify message creation using ICAO-compliant forms
  • Save draft messages for future use or setup message templates to reduce repetitive data entry
  • Manage contacts using personal and global address books from the directory server
Ubimex Web allows system administrators to configure, maintain and monitor AMHS operations using a graphical user interface:
  • Manage users, groups, rights & privileges
  • View logs of messaging transactions & system events
  • Configure internal AMHS & AFTN system parameters
  • Monitor the status of system processes & components
  • Run diagnostics to test system performance

Ubimex is designed for 24/7 operations in a mission-critical environment:

  • No-Single-Point-of-Failure anywhere within the system
  • Master & Hot-Standby server architecture with automatic switchover mechanism
  • Multiple LANs to ensure network connectivity
  • ‘n’ Replication seamlessly replicates messages from the Master server to any number (’n’) of Standby servers
  • No blind database replication; ‘n’ Replication uses shared memory replication at the application level
  • Defined process of replication confirmations ensures both the Master & Standby ubiMS are independent but in lock-step
  • Standby servers can be co-located with the Master or separated geographically at Disaster Recovery Locations
  • Software Process Auto-Recovery monitors key applications to detect abnormalities and initiate process restarts
