Nosaukums | <p>This QOS Framework is a structured collection of concepts and their relationships which describes QOS (Quality of</p> <p>Service) and enables the partitioning of, and relationships between, the topics relevant to QOS in Information</p> <p>Technology (IT) to be expressed by a common means of description. In particular, this QOS Framework is directed at IT</p> <p>systems and their use in providing Open Distributed Processing services.</p> <p>This QOS Framework is intended to assist those designing and specifying IT systems, and those defining</p> <p>communications services and protocols, by providing guidance on QOS applicable to systems, services and resources of</p> <p>various kinds. It describes how QOS can be characterized, how QOS requirements can be specified, and how QOS can</p> <p>be managed.</p> <p>This QOS Framework defines terminology and concepts for QOS in IT. It introduces the concept of QOS characteristics,</p> <p>which represent the fundamental aspects of QOS that are to be managed in various ways; and it defines a number of</p> <p>QOS characteristics of particular importance. These definitions are independent of how QOS is represented or controlled</p> <p>in a real system.</p> <p>This Framework describes how QOS requirements can be expressed, and identifies a number of QOS mechanisms (such</p> <p>as three-party negotiation) that can be used as components of QOS management functions to meet QOS requirements of</p> <p>various kinds. It also describes the circumstances in which various combinations of mechanisms may be appropriate.</p> <p>This QOS Framework provides a basis for the specification of extensions and enhancements to existing or planned</p> <p>standards, as a result of the need for, and application of, the QOS concepts defined in this Recommendation |</p> <p>International Standard. It is not the intent of this Recommendation | International Standard to destabilise any existing</p> <p>Recommendations | International Standards; rather, it is intended that this QOS Framework may be used by:</p> <p>· developers of new or revised IT-related standards which define or use QOS mechanisms; and</p> <p>· IT users expressing requirements for QOS.</p> <p>This QOS Framework does not attempt to provide a basis for the specification of performance objectives or network</p> <p>signalling of QOS in public communications networks. The QOS aspects of these communications services are</p> <p>addressed by other ITU-T Recommendations.</p> <p>The intent of this Recommendation | International Standard is to provide a common vocabulary to both service providers</p> <p>and service users. Nothing in this Recommendation | International Standard should be construed as placing requirements</p> <p>on either service providers or service users. It is hoped that a common approach and vocabulary for QOS will assist</p> <p>multiple service providers to deliver end-to-end QOS to end-systems.</p> <p>This QOS Framework specifically excludes the detailed specification of QOS mechanisms. It is not the intent of this</p> <p>Recommendation | International Standard to serve as an implementation specification, to be a basis for appraising the</p> <p>conformance of implementations, or to define particular services and protocols. Rather, it provides a conceptual and</p> <p>functional framework for QOS which allows independent teams of experts to work productively on the development of</p> <p>Recommendations | International Standards.</p> <p>As applied to OSI, this QOS Framework is consistent with the OSI Basic Reference Model in that it describes operations</p> <p>and mechanisms which are assignable to layers as specified in the OSI Basic Reference Model. It is consistent with the</p> <p>OSI Management Framework (see ITU-T Rec. X.700 | ISO/IEC 7498-4) and the Systems Management Overview (see</p> <p>ITU-T Rec. X.701 | ISO/IEC 10040) in its assignment of functions to management entities. In Annex A, this QOS</p> <p>Framework presents a model of QOS for OSI which identifies the entities that participate in the management of QOS,</p> <p>defines the flow of QOS-related information between them and describes how this information is used.</p> |
