1. Introduction

1.1 Backgrounds The Internet Protocol (IP) is the primary protocol used for relaying the network packets from source to destination through the Internet. It was initially designed in 1974 by Vint Cerf and Bob Kahn to connect systems that are in different geographical locations(Conta, 2012, pp. 49-51). The term "Internet," simply means Internetwork, that is, a connection between multiple networks. During the early stages of development, this protocol was used only by the military and research universities, but gradually, computers from companies and additional universities were added(Hinden, 2012, pp. 102-106). Today, much of the world's population is becoming more connected to and reliant on the Internet(Sailan, Hassan, & Patel, 2009, pp. 133-136).

Internet Protocol is the backbone of the Internet. It specifies how independent networks can work together to form a global network. Each of the hosts connected to the Internet has an associated IP address(Radwan, 2011, pp.121-123). Packets are exchanged between these hosts. A source and a destination IP address are assigned with in a packet and forwarded into the network (Narten, 2011, pp. 166-168). When packets are sent to a host, which is not located within the same network as the source host, networking devices such as routers, are used to receive packets from the source host and forward it one step closer to the location of the network where the destination host resides(Convery, 2013, pp. 11-13).

The concept of forwarding packets arrived as a new idea to early research scientists. The telephone network was a global network which did not use the concept of packet forwarding. Telephone networks used a circuit switch implementation, consisting of a fixed circuit source arid destination (Caicedo, Joshi & Tuladhar, 2009, pp.162-165). All the traffic was sent over this connection. With the advent of IP, packets do not travel along established fixed circuits. The packets are addressed with a source and destination address; then forwarded through the network(Hermann, 2012, pp. 121-126).

IP allows a packet to be forwarded through different networks in order to reach the destination. These individual networks may define their own rules of sending data through their routing devices with each network adhering to their respective rules. IP allows a packet to adapt to each of the individual networks as it traverses. The size of the packet may vary from ...
