ISO reference model

For the data exchange between systems various prerequisites have to be met by the two
communication partners. Both stations must have compatible physical interfaces, and the form
of information routing, addressing, the type of error checking and the format of the information
have to be agreed by both communication partners.
For this reason, the International Standards Organization (ISO) has established a model for
communication procedures known as the ISO reference model.
