The two models are often briefly called the 5-layer and 7-layer models the 5-layer although all major (and many minor) computer vendors now have osi products, the osi protocols were never widely implemented, and tcp/ip has become the. This sample chapter explores network models, specifically the osi 7-layer model and the tcp/ip 5 network protocols are modular by design and function at specific layers of a hierarchical protocol stack each layer in the hierarchy provides services to the layer above it and uses the services. As such, networking professional can use these models to describe the behavior of protocols and applications in the osi model, data is passed from one layer to the next where the data proceeds back up the hierarchy.

Is an osi protocol deployment clns is the service provided by the connectionless-mode network protocol (clnp) clnp is widely used in many telecommunications networks around the world because is-is (an osi routing protocol) is mandated by the itu-t as the protocol for management of synchronous digital hierarchy (sdh) elements.
