MATIP-Type B
MATIP-Type B (Mapping of Airline Traffic over Internet Protocol) facilitates the transmission of traditional airline reservation and operational traffic over IP networks. It allows legacy airline proprietary protocols to be encapsulated and sent across TCP/IP or UDP/IP, enabling seamless integration with modern communication infrastructure while maintaining support for existing airline applications..
The MATIP protocol, standardized by IETF as RFC 2351, enables airline applications relying on proprietary protocols like SITA X.25 to migrate onto IP-based networks efficiently. MATIP is designed to map various airline-specific message formats into TCP or UDP datagrams, offering support for applications such as reservations, messaging, and operational data. It acts as a lightweight encapsulation, maintaining data integrity and protocol framing inside the IP transport.
Port 351 is designated for MATIP-Type B sessions, typically used for server-side implementations receiving client connections. MATIP provides a minimalistic approach, simplifying the adaptation layer between legacy airline data streams and modern IP stacks without requiring complex gateways. It supports both connection-oriented (TCP) and connectionless (UDP) transport, granting flexibility based on performance or reliability needs.
Due to its functionally critical role within airline data infrastructure, MATIP promotes interoperability among carriers and service providers, reducing reliance on expensive legacy networking solutions. Its implementation allows airlines to continue using existing back-office systems over newer, cost-effective IP networks, improving scalability and maintaining compliance with aviation communication standards.
