IPv4 and IPv6 Quality of Service First In First Out (FIFO) Using OPNET Simulator

Ali Ibrahim Yahia Mahmoud, Dr. Amin Babiker Abdel-Nabi Mustafa

Abstract: The quality of service is one of the most important areas of Internet development. As the Internet originally developed for data communications is now used more and more for real-time applications, there is a need for better service than the ``best effort'. In this study we will at first review the concept quality of service, what it is and then we study the two most important efforts to provide. The remarkable growth of the Internet Protocol version 4 (IPv4) -based Internet has highlighted several fundamental limitations with that protocol. Internet Protocol version 6 (IPv6) addresses these issues and provides additional enhanced services and functionality. IPv6, also called IP-NG (is the next generation) Internet Protocol and is the designated successor to IPv4. Although some aspects of IPv6 are still under development, the basic protocols, conventions, and formats have been stable for years and enjoy wide support. Real-world production deployment (allocation and assignment of production network addresses or prefixes) has been underway for several years, and IPv6 is no longer considered experimental.
