CAN/CSA-Z243.150-88 (R1999)

Scope 

This International Standard defines in an abstract way the externally visible service provided by the OSI Session 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 sequence of these actions and events.
 
The service defined in this International Standard is that which is provided by the OSI session protocol (in conjunction with the transport service) and which may be used by the OSI presentation protoco l.
 
This International Standard does not specify individual implementations or products, nor does it constrain the implementation of entities and interfaces within a computer system. There is, therefore, no conformance to this Internatio nal Standard.
