CAN/CSA-ISO/IEC-8072-95 (R1999)

The international community has decided to make this standard available only in the English language version. It has been adopted as a National Standard of Canada on this basis. This National Standard of Canada is equivalent to International Standard ISO/IEC 8072:1994. 1 Scope This Recommendation | International Standard defines in an abstract way the externally visible service provided by the OSI Transport Layer in terms of: a) the primitive actions and events of the service; b) the parameter data associated with each primitive action and event; c) the relationship between, and the valid sequences of, these actions and events. The service defined in this Recommendation | International Standard is that which is provided by all OSI Transport Protocols (in conjunction with the Network Service) and which may be used by any OSI Session Protocol. This Recommendation | International Standard does not specify individual implementations or products, nor does it constrain the implementation of entities and interfaces within a system. Comformance of equipment to this Recommendation | International Standard is achieved by conformance to the protocols specified to fulfil the Transport Service defined in this Recommendation | International Standard,
