Open Systems Interconnect

networking (OSI-RM, OSI Reference Model, seven layer model)

A model of network architecture and a suite of protocols (a

protocol stack) to implement it, developed by ISO in 1978

as a framework for international standards in heterogeneous

computer network architecture.

The OSI architecture is split between seven layers, from

Each layer uses the layer immediately below it and provides a

service to the layer above. In some implementations a layer

may itself be composed of sub-layers.

OSI is the umbrella name for a series of non-proprietary

protocols and specifications, comprising, among others, the

OSI Reference Model, ASN.1 (Abstract Syntax Notation 1), BER

Information Protocol and Services), X.400 (Message Handling

System, or MHS), X.500 (Directory Service), Z39.50 (search

and retrieval protocol used by WAIS), and many others.

Apart from its actual application to real protocols, it also

serves as a useful teaching model.
