The OSI reference model

  title={The OSI reference model},
  author={John Day and Hubert Zimmermann},
  journal={Proceedings of the IEEE},
The early successes of computer networks in the mid-1970's made it apparent that to utilize the full potential of computer networks, international standards would be required. [] Key Method The paper first describes the basic building blocks used to construct the network model. Then the particular seven-layer model used by OSI is briefly described, followed by a discussion of outstanding issues and future extensions for the model.

A Performance Model of the OSI Communication Architecture

The analytical model proposed in this paper aims at predicting the performance of software implementations which would be built according to the OSI basic reference model, which is basically a closed multiclass multichain queueing network with a processor-sharing center modeling process contention at the processor and a delay center modeling times spent waiting for responses from the corresponding peer processes.

Application Specific Optimization of Ethernet Cluster Communication

The implementation of a networking protocol, which is adopted from a previous work, is refined to a state where it is ready for production use and it is demonstrated that the protocol gives usable results with real-world scientific applications.

Efficient High-Level modeling in the networking domain

This paper will propose an efficient actor-oriented modeling approach for complex systems by integrating hierarchical FSMs into dynamic dataflow models, and providing new channel types to allow concurrent processing of multiple connections.

General theorems are developed and architectural breakouts of the layers of the Reference Model are analyzed to address minor inconsistencies in layer services and tunctions presently specified in OSI documents.

Local-Area Distributed Systems

The forces leading to distributed systems and the obstacles to realizing the full value of the systems are discussed and systems that represent the main approaches are described.

A design strategy for the complete OSI Reference system is presented and some implementation options in the Transport protocol (class 4) which can enhance the performance of the system are discussed.

OSI Reference Model A Seven Layered Architecture of OSI Model

In July 1979 the specification of this architecture was passed under the name of “(OSI) Reference Model” to Technical committee 1997 “Data processing” along with the recommendations to start

An Estelle compiler

This document describes the design and implementation of one of the few existing compilers for the one such FDT, the language "Estelle" ([IS085], [IS086], (IS087]).

SNA: Current Requirements and Direction

Known requirements for enhanced application and transaction services, for additional provisions for very large networks, for continuing adaptation of small-system and transmission media advances, for inclusion of additional management capabilities, and for further integration of network standards are discussed.



Presentation and major design aspects of the CYCLADES computer network

A computer network is being developed in France, under government sponsorship, to link about twenty heterogeneous computers located in universities, research and D.P. Centers to provide various departments of the French Administration with access to multiple data bases located in geographically distant areas.

Computer network development to achieve resource sharing

An overview of the need for a computer network, the requirements of a computer communication system, a description of the properties of the communication system chosen, and the potential uses of such a network are described.
