Open Systems Interconnections Protocol

Open Systems Interconnection Protocol The Open System Interconnection Protocol is a model for international means. Regardless of the network architecture, this model enables communication between various hardware systems and software systems around the world. Without a similar protocol, the Internet itself and other various communication methods are very limited. The open system interconnection model is mainly used for computers and devices communicating via a network or other network, but it can also be implemented locally between two devices.

Initially, the Open Systems Interconnection (OSI) model was designed by the International Organization for Standardization (ISO) to provide a framework for building open system protocols. Vision is that this agreement will be used to build an international network that is independent of its own system. Unfortunately, due to the speed of use of the TCP / IP based Internet and its expansion speed, the OSI protocol suite was developed and accepted. Protocols currently being developed using OSI specifications are rarely used widely, but the seven-layer OSI model makes a significant contribution to the development of other protocols and products for all types of new networks did.

Since Sowa's article, there are more examples. OSI (Open Systems Interconnection) is a major international effort to create "comprehensive, if not all, inexpensive and agile transmission control protocols and computer network standards to replace Internet Protocol (TCP / IP) . As pioneering researcher Einar Stefferud said, "OSI is a beautiful dream, TCP / IP is its life." The common point for winning the fact is to simplify "promote effective expansion" and promote broader recruitment. The Xanadu project is a competitor of the World Wide Web, but the more ambitious feature set of the former is not comparable to the network limitation, and the core has a minimal protocol (HTTP) and a simple data format (HTML) included.
