Compare and Contrast Tcp/Ip and Osi Models - 1528 Words

The two, OSI and TCP/IP are Standardized Protocol Architectures developed specifically for: 1. Devices to communicate 2. Vendors to have more marketable products 3. Customers to insist on standards based equipment The OSI is a reference model whilst TCP/IP is the suite which is the most widely used. Description of Open Systems Interconnection (OSI Model) Developed by the International Organization for Standardization (ISO) It is made up of seven layers and each layer: 1. performs a subset of the required communication functions 2. relies on the next lower layer to perform more primitive functions 3. provides services to the next higher layer 4. Changes in one layer should not require changes in other layers The layers can be†¦show more content†¦http, SMPT Relationship between OSI and TCP/IP Models Approach OSI Model TCP/IP Horizontal Approach Vertical Approach 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 TCP/IP, each application entity is composed of whatever set of function it needs beyond end to end transport to support a distributed communications service. In OSI, each distributed application service selects functions from a large common â€Å"toolbox† of application service element (ASEs) and complements these with application service elements that perform functions specific to given end-user service Most of these application processes builds on what it needs and assumes only that an underlying transport mechanism (datagram or connection) will be provided. Reliability OSI Model TCP/IP Emphasis on providing a reliable data transfer service Treats reliability as an end-to-end problem Each layer of the OSI model detects and handles errors, all data transmitted includes checksums. The transport layer of the OSI model checks source-to-destinationShow MoreRelatedTcp/Ip674 Words   |  3 PagesThe Transmission Control Protocol/Internet Protocol (TCP/IP) suite is indisputably one of the most popular networking protocol suites ever developed. TCP/IP is an industry standard designed for large networks consisting of network segments connected by routers, and is the protocol used on the Internet (Hillpot Ivy, 2005). TCP/IP’s roots can be traced back to research conducted by the United States Department of Defense (DOD) Advanced Research Projects Agency (DARPA) as early as 1960.
