Information technology. Open systems interconnection. Connectionless presentation protocol. Protocol specification | Status: Project Underway, Current

1 Scope This Recommendation | International Standard1)specifies

1. a) procedures for the transfer of data and control information from one presentation-entity to a peer presentation-entity ;
2. b) the structure and encoding of the presentation-protocol-data-units used for the transfer of data and control information.

The procedures are defined in terms of

1. c) the interactions between peer presentation-entities through the exchange of esentation-protocol-data-units;
2. d) the interactions between a presentation-entity and the presentation-service-user in the same system through the exchange of presentation-service primitives;
3. e) the interactions between a presentation-entity and the session-service-provider through the exchange of session-service primitives.

These procedures are defined in the main text of this Recommendation | International Standard supplemented by state tables in Annex A. These procedures are applicable to instances of communication between systems which support the Presentation Layer of the OSI Reference Model and which wish to transfer presentation service data units using connectionless-mode presentation service primitives. This Recommendation | International Standard also specifies conformance criteria for systems implementing these procedures. It does not contain tests which can be used to demonstrate this conformance.
