SNA initially aimed at competing with ISO's Open Systems Interconnection, which was an attempt to create a vendor-neutral network architecture that failed due to the problems of " design by committee ".

The Open Systems Interconnection ( OSI ) model ( ISO / IEC 7498-1 ) is a conceptual model that characterizes and standardizes the internal functions of a communication system by partitioning it into abstraction layers.
23.
In the 1970s, two organizations, the International Organization for Standardization ( ISO ) and the The Basic Reference Model for Open Systems Interconnection, was published by ISO and as standard X . 200 by the ITU-T.
24.
NTCIP refers to levels in NTCIP, rather than layers to distinguish the hierarchical architecture applied from those defined by the Open System Interconnection Reference Model ( OSI Model ) of ISO and the Internet Engineering Task Force ( IETF ).
25.
The Open System Interconnection ( OSI ) reference model was developed under the auspices of the International Organization for Standardization ( ISO ) and provides a rigorous description for layering protocol functions from the underlying hardware to the software interface concepts in user applications.
26.
The application layer in the TCP / IP model is often compared as equivalent to a combination of the fifth ( Session ), sixth ( Presentation ), and the seventh ( Application ) layers of the Open Systems Interconnection ( OSI ) model.
27.
The details of implementation and semantics of the Transport Layer of the TCP / IP model ( RFC 1122 ), which is the foundation of the Internet, and the Open Systems Interconnection ( OSI ) model of general networking, are easily compared.
28.
Even when the layers are examined, the assorted architectural documents there is no single architectural model such as ISO 7498, the Open Systems Interconnection ( OSI ) model have fewer and less rigidly defined layers than the OSI model, and thus provide an easier fit for real-world protocols.

In the midst of this IBM ( the then market leader in computing ) and BT attempted to launch a joint venture, called Jove, for managed SNA services in the UK . And for a time significant extra expenditure was allowed for BT's data services, PSS being the major part, as one concern of regulators was this joint venture might damage work on Open Systems Interconnection.
