Application Services Layer

The uppermost layer of the Internet protocol suite (TCP/IP) is the Application Services Layer. Here we find the definition of some of the basic network services, tools, and utilities that are used by many user applications. Unlike the OSI Reference Model (OSI-RM), this layer does not merely define protocols, but in some cases also defines the applications themselves. The TCP/IP community is a little less clear in defining the boundary between the application and the protocol than the ISO was.

Some of the more important Applications Services Layer protocols include:

Other Application Services protocols are listed below.
