The OSI (Open Systems Interconnection) model is a standard defined by the International Organization for Standardization that defines a layered protocol architecture for data communication. A layer of functionality in one computer communicates with its peer layer in other computers. This is discussed under "Network Architecture."
The session layer provides protocols that applications use to establish sessions with one another across a network or other communication system. The session layer is not used much in modern network communications because it was primarily designed to specify how sessions are set up between remote time-sharing systems. Authentication routines are defined in this layer.
