The Effect of IPv4 and IPv6 Over Network and Application Servers Load and Delay

Abstract

IP internet protocol is the set of technical rules or standards which set forth that how computer communicates over a network. Internet protocol version 4 IPV4 has been introduced in 1981. But the growth of internet applications causes space exhausting . Moreover, IPV4 based internet causes problems of IP addressing space depletion and routing overhead[1] . Some temporary solutions were offered, such as NAT (Network Address Translator) or CIDR (Classless InterDomain Routing) , however work began on a new Internet Protocol, namely IPv6[2]. IPv6 is a new version of internet protocol designed as a successor to the current ipv4[1]. The main reason for a new version of the Internet Protocol was to increase the address space; IPv6 was designed with a 128 bit address scheme, enough to label every molecule on the surface of the earth with a unique address [2]. IPv6 - originally known as IPng- has been selected from several proposed alternatives as a suitable successor of the existing Internet Protocol (IPv4) [3]. Most of the existing protocol stacks, systems and applications run on IPv4-based systems. Changes to these systems can have significant impact on existing applications and must therefore be carefully implemented. While a principal design objective of IPv6 was to ease the transition from and coexistence with IPv4, the migration of IPv4-based systems to IPv6 will be a major challenge despite IPv6’s built-in features that are backward-compatible with IPv4[4]. It is envisioned that the transition from IPv4 to universal IPv6 will not happen in the near future
