ISO IEC 14753:1999 pdf download – Information technology一Open Distributed Processing一. Interface references and binding.
Interface references are crucial to interworking between ODP systems and federation of groups of ODP systems. An interface reference embodies the information needed to establish bindings, including binding to objects at nodes that support several different communication protocols and binding to objeets in different management domains. An interface reference further embodies the information required for the engineering mechanism to maintain bindings between computational objects in the presence of distribution transparencies such as migration transparency. They are the foundation of OL)P location and relocation transparency
This Recommendation p Intemational Standard includes:
• a franwwiirk for binding interfaces and a generic binding prous.’oI (for both stream and operational interfaces);
• a specification of the genenc information structure of interface references (for both stream and operational interfaces):
• representation(s) for interface references when transferred using standardized protocols:
• identification of procedures for the management and transfer of interface references with respect to individual transparencies;
• identification of node nsanagensent interfaces related to binding and federation which create or transfonn interface references;
• identification of requirements for quality of service infortnation and for invocation of QoS or related measurement procedures.
This Recommendation I International Standard provides an engtneering description of the lunctionality needed to support the computational binding of objects in 01W systems. Security and support for group communication are important issues, hut not within the scope of this Recommendation I International Standard

The following Recommendations and International Standards contain provisions which, through reference in this test. constitute provisions of this Recommendation I International Standard. At the tOne of publication, the editions indicated were valid. All Recommendations and Standards are subject to revision, and parties to agreements based on this Recommendation I International Standard are encouraged to investigate the pos.sibility of applying the most recent edition of the Reconinsendations and Standards listed below, Members of lEC’ and ISO maintain tegisters of currently valid International Standards. The Telecommunication Standardization Bureau of the ITU maintains a list of the currently valid ITU-T Recommendations.
The objective of ODP standardization is to develop standards that realize the benefits of distributing information processing services in a heterogeneous environment of IT resources and mutiple organizational domains. These standards address constraints on system specifications and provide a system infrastructure that addresses diffculies
inherent in the design and programming of distributed systems.
Distributed systems are important because of a grow ing need to interconneet information processing systems. This need arises because of organizational trends (such as downsizing), which demand the exchange of information not only between groups within an organization but also between cooperating organizations. Technological advances make it possible to respond to these trends giving increased importance to information networks and personal workstations, and
enabling distributed applications to be constructed :CTO88 large configurations of interconneeted systems.
In order to set up cooperation between organizations and their information systems. the parties must define and agree on a relationship and then maintain it. This relationship is ofen defined as a contract in commercial environments. To achieve cooperation between systems, after some initial contact, agreements must be made, contracts negotiated and intrfaces defined, created and made available. Interworking between ODP systems requires standardized communication methods between objects that reside at autonomous systems.
This Recommendation I Intermational Standard provides a framework for binding. incuding a refinement of the binding model of ITU-T Rec. X.903 I ISO/IEC 10746-3 and a generic structure of interface references. This Recommendation Intermational Standard is structured according to ODP view points.
