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-T). 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 the Technical Committee and has been approved as a National Standard of Canada by the Standards Council of Canada. Scope This Recommendation | International Standard is based on the framework of abstractions and concepts developed in the Reference Model for Open Distributed Processing (ITU-T Rec. X.902 | ISO/IEC 10746-2 and ITU-T Rec. X.903 | ISO/IEC 10746-3). This Recommendation | International Standard defines how interactions between computational objects in a computational specification of a system relate to protocol support for those interactions in an engineering specification of that system. In particular it: - defines a General Interworking Framework (GIF); - within the GIF, defines a set of facilities each comprising a set of functionally-related service primitives as abstract definitions of the interactions of basic engineering objects and channel objects; - defines the parameters of the service primitives of the GIF; - defines the permitted sequence of the service primitives by means of state tables; - specifies, in annexes, the mapping of the GIF service primitives and their parameters to the messages and fields of particular protocols. As specified in this Recommendation | International Standard, the GIF defines protocol support for a pragmatic subset of the possible computational interactions defined in ITU-T Rec. X.903 | ISO/IEC 10746-3. It is also restricted in the features of the protocol support and the supported transparencies. The GIF, as specified here, defines: - support for computational operations, but not for streams; - support using stub, binder and protocol objects hierarchically, such that any interaction at the interworking reference point of the supporting protocol object supports liaisons of one of those objects or of the basic engineering object, and any interaction to support those liaisons is passed via that interworking reference point; and - interactions at a single interworking reference point, from the perspective of one side; interceptors are not explicitly considered; NOTE 1- It is intended that the GIF could be extended, in a future amendment, to support streams and flows. The present specification is restricted to areas that are technically stable. The GIF supports at least some forms of: - access transparency; and - location transparency. The GIF as specified here also supports a limited equivalent of relocation transparency. Other transparencies are not addressed in this present specification. NOTE 2 - It is intended that the GIF could be extended, in future amendments, to support additional transparencies. The GIF does not explicitly model Quality of Service requirements. The application of security-related issues to the GIF are not included in the current text and are for further study. The set of mappings to particular protocols specified in annexes to this Recommendation | International Standard is not exhaustive. The GIF could be mapped to other protocols. NOTE 3 - In particular, a mapping to the DCOM protocol family would be a candidate for an additional annex.
