1.6 Protocol Stack Architecture

Protocol stack architecture defines how service delivery may require different functions to be divided along well-defined boundaries so that responsibilities can be decoupled. It does not describe how actual resources might be used or needed. There are different types of protocol stack architecture. Some of them are OSI reference model, IP protocol stack architecture etc.

OSI:

		An ISO standard for worldwide communications that defines a networking framework for implementing protocols in seven layers.
		Control is passed from one layer to the next, starting at the application layer in one station, and proceeding to the bottom layer, over the channel to the next station and back up the hierarchy.

IP protocol stack architecture:

		A set of network protocol layers that work together.
		The OSI Reference Model that defines seven protocol layers is often called a stack, as is the set of TCP/IP protocols that define communication over the internet. (For details see subsequent pages).
