This is a list of network protocols, categorized by their nearest Open Systems Interconnection (OSI) model layers. This list is not exclusive to only the OSI protocol family. Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP)...
The Open Systems Interconnection model (OSI model) is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system without regard to their underlying internal structure and technology.
TCP/IP is the communication protocol to connect hosts to the Internet, while OSI is a reference model for communication between end users in the network.
Work on the OSI model began in the late 1970s, mostly as a reaction to the growing influence of big companies like IBM, NCR, Burroughs, Honeywell (and others) and their proprietary protocols and hardware.
The Open System Interconnection (OSI) protocol suite is comprised of numerous standard protocols that are based on the OSI reference model. These protocols are part of an international program to develop data-networking protocols and other standards that facilitate multivendor...
The OSI model has been around since 1977. It is simply a set of protocols which govern the various aspects of networking. This Buzzle article presents information about the various layers of the OSI reference model.
