CSA Preface
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-I).
This International Standard was reviewed by the CSA TCIT under the jurisdiction of the Strategic Steering Committee on Information Technology and deemed acceptable for use in Canada. (A committee membership list is available on request from the CSA Project Manager.) From time to time, ISO/IEC may publish addenda, corrigenda, etc. The CSA TCIT will review these documents for approval and publication. For a listing, refer to the CSA Information Products catalogue or CSA Info Update or contact a CSA Sales representative. This Standard has been formally approved, without modification, by these Committees and has been approved as a National Standard of Canada by the Standards Council of Canada.
Scope
This Recommendation / International Standard provides the framework for the realization as an OSI application context of the abstracts concepts of operation package and association contract defined in ITU-T Rec. X.880 / ISO/IEC 13712-1. Such an application context is described in terms of a collection of application service elements, in particular the Remote Operations Application Service Element (ROSE), which drives the general purpose protocol for invoking and reporting the returns of arbitrary operations.
The terms, definitions, and mechanisms defined in ITU-T Rec. X.880 / ISO/IEC 13712-1 apply here and are specialized for an OSI realization as specified in this Recommendation / International Standard. This Recommendation / International Standard focuses on the services provided by ROSE, and the way ROSE is used. The ROSE services are provided by the use of the ROSE protocol (specified in a companion Recommendation / International Standard, ITU-T Rec. X.882 / ISO/IEC 13712-3), in conjunction with the Association Control Service Element (ACSE) services (ITU-T Rec. X.217 / ISO 8649) and the ACSE protocol (ITU-T Rec. X.227 / ISO 8650), and, optionally, the Reliable Transfer Service Element (RTSE) services (ITU-T Rec. X.218 / ISO/IEC 9066-1) and the RTSE protocol (ITU-T Rec. X.228 / ISO/IEC 9066-2), and the Presentation service (ITU-T Rec. X.216 / ISO/IEC 8822).
No requirement is made for conformance to this Recommendation / International Standard.
