CSA Group Technologies de l'information - Protocole assurant le service de transport en mode sans connexion de l'OSI (norme ISO/CEI 8602:1995 adoptée)

Scope This Recommendation/International Standard specifies (a) procedures for the connectionless-mode transmission of data and protocol control information from one transport entity to one peer transport entity. (b) the encoding of the transport-protocol-data-units used for the transmission of data and control information; (c) procedures for the correct interpretation of transport protocol control information; and (d) the functional requirements for implementations claiming conformance to this Recommendation/International Standard. The procedures are defined in terms of (a) the interactions among peer transport entities through the exchange of transport-protocol-data-units; (b) the interactions between a transport entity and a transport service user through the exchange of transport service primitives; and (c) the interaction between a transport entity and a network service provider through the exchange of network service primitives. This Recommendation/International Standard specifies the connectionles s-mode transport protocol and provides the PICS Proforma in compliance with the relevant requirements, and in accordance with the relevant guideline, given in CCITT Rec. X.291 / ISO/IEC 9646-2. The protocol for providing the connection-mode transport service is specified in ITU-T Rec. X.224 / ISO/IEC 8073.
