TCP/IP and OSI Modal
OSI Reference Model:-
The seven layers of the OSI model are as follows:
· Physical layer: Converts the data into the stream of electric or analog pulses that will actually cross the transmission medium and oversees the transmission of the data
· Data Link layer: Provides an interface with the network adapter; maintains logical links for the subnet
· Network layer: Supports logical addressing and routing
· Transport layer: Provides error control and flow control for the internetwork
· Session layer: Establishes sessions between communicating applications on the communicating computers
· Presentation layer: Translates data to a standard format; manages encryption and data compression
· Application layer: Provides a network interface for applications; supports network applications for file transfer, communications, and so forth
TCP/IP Protocol Architecture
TCP/IP protocols map to a four-layer conceptual model. The four layers of model are: Application, Transport, Internet, and Network Interface. Each layer in model corresponds to one or more layers of the seven-layer Open Systems Interconnection (OSI) model.
The APRANET initially started with four Internet message processors (IMPs), located at the UCLA, UCSA, Stanford research institute and the University of Utah. In the early years, the purpose and usage of the APRANET network was widely discussed, leading to many enhancements and modifications as the users steady increased and requested demanded more from the network. As time passed many enhancements were made to the existing protocol but by 1973 it was clear that NCP (Network Control Protocol) was unable to handle the volume of traffic passing through it network and proposed a new functionality. A new protocol TCP/IP Transmission Control Protocol / Internet Protocol was developed over time to replace NCP.

Abstract
In today's world as technology is growing people are looking to adopt new technologies which offer them a feasible and easy access to the resources with a security that makes them away from common threats. This paper introduces the introduction to the internet protocols and concept of the IPV4 and IPV6, as well what are the disadvantages in the IPV4 and the advantages in IPV6. This paper describes the future concepts of the IPV6 and the future impact of the IPV6 on the network field by describing a brief history of the internet protocols and the statistical representation of the IPV6 users.
Introduction
Transport layer is the basic layer in the OSI and the TCP/IP model. The basic task of this layer is to send or receive the data or voice and video data grams or packets over the internet. IPV 4 is meant for Internet Protocol version 4. The network protocol that has been used in the Internet since its inception is IPv4 , which provides 2^32 distinct addresses. Its successor IPv6(Internet Protocol Version 6) provides 2^128 addresses, but IPv6 adoption has not proceeded as quickly as its designers expected (Erik Kline,2011). The main need for the migration to IPV6 from IPV4 is mainly for the ip addresses . IPv4 provides approximately 4.3 billion of ip addresses but there is a need for more ip addresses. For that reason they introduced IPV6.
History
The current trend of the Internet Protocol IPv4 was initially grown in the 1970s, and the primary convention standard RFC 791 that administers IPv4 usefulness was distributed in 1981. With the remarkable extension of Internet use - particularly by highly populated nations like India and China. The approaching deficiency of loca ...
As we deep dive into TCPIP and OSI protocols, looking at each .docxhanneloremccaffery
As we deep dive into TCP/IP and OSI protocols, looking at each one’s architecture. TCP/IP consists of four to five layers application, transport, network, data link, and physical. OSI (International Organization for Standardization) consists of seven layers application, presentation, session, transport, network, data link, and physical.
Both Protocols use application for their first layers. The application layer supports applications and sometimes support services such as encryption and compression. Which user applications like browser and word processing applications are not found within this layer they use protocols that function within the application layer. Application Protocols used for TCP/IP and OSI include HTTP (Hypertext Transfer Protocol) which allows browsers and servers to send and receive web pages. SMTP (Simple Mail Transfer Protocol) enables users to send and receive emails. FTP (File Transfer Protocol) moves files from one computer to another. SSH (Secure Shell) allows remote computers to securely log in to other computer systems. SNMP (simple Network Management Protocol) manages the numerous elements in a computer network to be managed at a single point.
Looking at the second layer of TCP/IP and OSI which they differ. TCP/IP second layer is the Transport Layer. Which uses TCP (Transmission Control Protocol) this allows for an error free end to end connection. TCP protocol is not the only protocol found in the Transport Layer. You can also find UDP (User Datagram Protocol) this is not commonly found within this layer and usually used when steaming data like music or videos. OSI uses the presentation layer for its second layer. We do not find this layer within TCP/IP. Which it performs functions for presenting data properly to the sender or receiver.
The Third layer of TCP/IP and OSI differ also. TCP/IP has the Network layer thirdly. The Network layer also known as Internet layer or IP layer is used to transfer data within, and between networks. IP (Internet Protocol) software which prepares packets of data for transmission between the networks. OSI third layer consists of the session layer and is not found within the layering of TCP/IP protocol. The session layer consists of transferring large amounts back and forth between two systems. It uses a point after each small section of transmission to ensure proper data transmission.
Now we are at the fourth layer of TCP/IP and OSI protocols. TCP/IP uses Data Link at this layer. Data Link layer which gets data from user’s workstations and passes it to the router connected to the Internet. Commonly the LAN gets the data from workstation to Internet. The Data Link Layer prepares data for transmission to a router sitting between the LAN and internet. OSI’s fourth layer is the second layer of TCP/IP, Transport Layer. Which verifies the data that arrived at the destination is the same sent from.

Internet protocol concepts and overview
1. Internet Protocol Concepts and Overview
IP is a very important protocol in internetworking; it wouldn't be an
exaggeration to say that you can't really comprehend modern networking
without a good understanding of IP. Unfortunately, IP can be somewhat
difficult to understand. This is probably because due to its importance, a large
amount of complexity has become associated with the protocol over the
years, to allow it to meet the many demands placed upon it.
Before diving into the details of how IP works, I feel it is worthwhile to take a
high-level look at IP and what it does. In this section I provide a brief
examination of basic concepts related to the Internet Protocol and how it
works. I begin with an overview of IP, how it operates in basic terms and the
most important characteristics of how it does its job. I then expand on this
discussion by describing the main functions of the Internet Protocol, which can
be used as an introduction to the remainder of the sections that explain IP in
considerably more detail. I conclude with a brief look at the history of
development of IP, its versions, and how it has spawned the development of
several IP-related protocols.
TCP/IP Lower-Layer (Interface, Internet and Transport)
Protocols (OSI Layers 2, 3 and 4)
The TCP/IP protocol suite is largely defined in terms of the protocols that
constitute it; several dozen are covered in this Guide. Most of the critical
protocols of the suite function at the lower layers of the OSI Reference Model:
layers 2, 3 and 4, which correspond to the network interface, internet and
transport layers in the TCP/IP model architecture. Included here are the all-
important Internet Protocol (IP) at layer 3 and Transmission Control Protocol
(TCP) at layer 4, which combine to give TCP/IP its name.
Due to the importance of these and other TCP/IP protocols at the lower
layers, this is the largest chapter of The TCP/IP Guide. It contains four
subsections. The first describes the two TCP/IP protocols that reside at the
network interface layer, layer 2 of the OSI model: PPP and SLIP. The second
describes a couple of “special” protocols that reside architecturally between
layers 2 and 3: ARP and RARP. The third covers the TCP/IP internet layer
(OSI network layer, layer 3), including IP and several other related and
support protocol. The fourth describes the TCP/IP transport layer protocols
TCP and UDP.
2. TCP/IP Internet Layer (OSI Network Layer) Protocols
The first two layers of the OSI Reference Model, the physical layer and data
link layer, deal primarily with physical network details. The various LAN,
WLAN and WAN protocols function primarily at these two layers to connect
devices to create networks, and perform functions such as physical
connection and signaling, media access control and local delivery of data
between devices on the same network. Above these layers, we move beyond
the hardware aspects of networking and closer to the more abstract realm of
software-related network functions.
The third OSI layer is the network layer. We are of course talking about
networks in this Guide, and it is no coincidence that the layer bearing that
name is one of the most important in comprehending how networks function. It
is here that we find protocols that tie networks together to create
internetworks, and also where cross-network addressing and routing are
performed. The network layer is also called the internet layer in the TCP/IP
model.
In this section I provide details for the various TCP/IP protocols that reside
architecturally at the TCP/IP internet layer / OSI network layer. Much of the
focus here is on the all-important Internet Protocol; the section covering IP
includes extensive coverage of IP version 4, IP version 6, and IP-related
protocols such as IPSec, Mobile IP and IP Network Address Translation
(NAT). The following three subsections cover IP support protocols such as the
Internet Control Message Protocol (ICMP) and IPv6 Neighbor Discovery (ND)
protocol, and the complete set of IP routing protocols.
Internet Protocol (IP/IPv4, IPng/IPv6) and IP-Related
Protocols (IP NAT, IPSec, Mobile IP)
The idea of singling out any one protocol as being more important than the
others in a network is kind of pointless, if you think about it. The protocols and
technologies work as a team to accomplish the goal of communication across
the network. Like any team, no single member can get the job done alone, no
matter how good they are. Still, if we were to try to pick a “most valuable
player” in the world of networking, a good case could be made that we have it
here in this section: the TCP/IP Internet Protocol (IP).
Even though it gets “second billing” in the name of the TCP/IP protocol suite,
IP is in fact the “workhorse” of TCP/IP. It implements key network-layer
3. functions including addressing, datagram handling and routing, and is the
foundation upon which other TCP/IP protocols are built. Even the ones lower
in the TCP/IP architecture such as ARP and PPP are easier to understand
when you know how IP works. In addition to the main functions implemented
by the IP protocol itself, there are also several protocols that have been
developed over the years that I call “IP-Related” because they are based on
IP but add new functionality or capabilities for special purposes.
In this section I provide considerable coverage of the TCP/IP Internet Protocol
and to several protocols that are closely related to IP. I begin with a section
that takes a general look at IP concepts and provides an overview of how IP
works. I then have a large section that looks at IP version 4, the current
version of the protocol that is in use on TCP/IP networks everywhere.
Following this I look at the “next generation” of IP, IP version 6. I then provide
sections covering three IP-related protocols: the IP Network Address
Translation protocol (IP NAT), the IP Security protocol set (IPSec), and the
adaptation of IP for mobile devices (Mobile IP).
IP Security (IPSec) Protocols
One of the weaknesses of the original Internet Protocol is that it lacks any sort
of general purpose mechanism for ensuring the authenticity and privacy of
data as it is passed over the internetwork. Since IP datagrams must usually
be routed between two devices over unknown networks, any information in
them is subject to being intercepted and even possibly changed. With the
increased use of the Internet for critical applications, security enhancements
were needed for IP. To this end, a set of protocols called IP Security or
IPSec was developed.
In this section I provide a brief description of IPSec concepts and protocols. I
begin with an overview of IPSec, including a discussion of the history of the
technology and defining standards. I describe the main components and
protocols of the IPSec suite, and its different architectures and methods for
implementation. I then move to actually discussing how IPSec works,
beginning with a description of the two IPSec modes (transport and tunnel)
and how they differ. I describe security associations and related constructs
such as the Security Parameter Index (SPI). The last three topics cover the
three main IPSec protocols: IPSec Authentication Header (AH), IPSec
Encapsulating Security Payload (ESP) and the IPSec Internet Key Exchange
(IKE).
