Comparison and Contrast between the OSI and TCP/IP Model

[attachment=18074]

Introduction

This presentation would discuss some comparison and contrast between the 2 main reference models which uses the concept of protocol layering.

Open System Interconnection Model (OSI)
Transport Control Protocol /Internet Protocol (TCP/IP)

The Session Layer

The Session layer permits two parties to hold ongoing communications called a session across a network.
Not found in TCP/IP model
In TCP/IP,its characteristics are provided by the TCP protocol.
(Transport Layer)

The Application Layer

The Application Layer is the top layer of the reference model. It provides a set of interfaces for applications to obtain access to networked services as well as access to the kinds of network services that support applications directly.

OSI - FTAM,VT,MHS,DS,CMIP
TCP/IP - FTP,SMTP,TELNET,DNS,SNMP

Although the notion of an application process is common to both, their approaches to constructing application entities is different.

ISO Approach

Sometime called Horizontal Approach
OSI asserts that distributed applications operate over a strict hierarchy of layers and are constructed from a common tool kit of standardized application service elements.
In OSI, each distributed application service selects functions from a large common toolbox of application service element (ASEs) and complements these with application service elements that perform functions specific to given end-user service
