Summary: This standard specifies the OSI session layer provided by the externally visible service: a) service primitive actions and events, b) with the primitive actions and events associated parameter data, c) primitive relationship between actions and events and effective order. As defined in this standard services are provided by OSI session protocol (together with transport services) provided, and can be used in OSI presentation protocol those services. This standard does not require the individual to achieve or product, nor an entity within a computer system and interface implementation restrictions, therefore, there is no conformance requirements of this standard. Symmetric synchronize functional unit with the text does not apply to the relevant ITU-T applications support.

Introduction

This standard is one of a set of standards in order to facilitate the development of computer systems interconnection. It is a set of standards and open systems interconnection (OSI) reference model as defined by other standards related. OSI reference model to interconnect standard Normalized range subdivided into a series of manageable size specification layer. The purpose of this standard is on the boundary of the session layer and the presentation layer reference model between the provision of services to the presentation layer is defined. meeting Then use the transport layer protocol services to provide session services. This standard also defines the protocol can take advantage of the characteristics of the session services. Figure 1 It illustrates the relationship between session service, session protocol, transport services and representation agreements between each standard. Diagram 1 OSI standards and other standards About session quality of service of this standard as described in Chapter 10, to recognize that, in order to pass through the Open Systems Interconnection (OSI) Reference Model Session quality of service of a comprehensive treatment of all layers, and each layer to ensure that their treatment and services to achieve the quality of services by a uniform manner (QOS) of the overall goal of the work is still in progress. Therefore, the future can add a Supplement to this standard, further reflecting the service Quality and comprehensive development.

1 Scope

This standard uses the following terms and abstract methods defined externally visible service provided by the OSI Session Layer. Primitive actions and events a) service; b) the parameter data with each primitive action and event associated; c) the relationship between the primitive actions and events and effective order. Service as defined in this standard is provided by the OSI session protocol (along with transport services), and can be used in OSI presentation protocol that These services. This standard does not specify individual implementations or products, nor be limited to the achievement of entities and interfaces within a computer system, therefore, does not exist In conformance requirements of this standard. Symmetric synchronize functional unit related to the text does not apply to ITU-T application support.
