However, in many applications the communicating computers may be of different types. This means that they may use different programming languages and, more importantly, different forms of (2) interface between user(application) program, normally referred to, as application processes, and the underlying communication services may be (3) .

In an attempt to alleviate this problem, (5) , in the late 1970s, formulated a reference model to provide a common basis (or the coordination of standards developments and to allow existing and evolving standards activities to be placed into perspective with one another.
