Next Generation Internet Protocol IPV6 Essay

IPv6 is more flexible in using protocols which, are mainly defined as the Request for Comment (RFC) that we discussed in the discussions. Protocols are defined in the RFC, but the name of the protocol will be something like Internet Protocol, Internet Control Message Protocol, Telnet Protocol, and many more. The reason why these Protocols are more flexible in the IPv6 is for one, the IPv6 is a newer technology than the IPv4, and the IPv6 also has more functionality and allows more flexibility in the protocols, whereas the

As we all know, the growth of computer networks continues to rapidly grow. The digital revolution has changed the way we work and communicate almost beyond recognition. Provided that, foreseeing the changes and potential compatibility problems, in the mid nineteen eighties, the international standard organization (ISO) developed a networking reference model to standardize how network systems communicate with each other. It is a logical model for how network systems are supposed to communicate with each other. It breaks down the different components of the network communication and puts them into layers which reduce complexity. This reference model consists of seven layers: Application Layer, Presentation Layer, Session Layer, Transport Layer, Network Layer, Data Link Layer, and the Physical Layer. Each layer provides a service to the layer above it in the protocol specification and then communicates with the same layer’s software or hardware on other computers. It's important to realize, that these layers are separated into 2 sets: Transportation Set (Laters 1- 4) and Application Set (Layers 5 – 7). More importantly, the OSI model is 7 logical

With admirable foresight, the Internet Engineering Task Force (IETF) initiated as early as in 1994, the design and development of a suite of protocols and standards now known as Internet Protocol Version 6 (IPv6), as a worthy tool to phase out and supplant IPv4 over the coming years. There is an explosion of sorts in the number and range of IP capable devices that are being released in the market and the usage of these by an increasingly tech savvy global population. The new protocol aims to effectively support the ever-expanding Internet usage and functionality, and also address security concerns.

1) Set of protocols developed to support the secure exchange of packets IPv4 and IPv6

The Internet Protocol (IP) has some vulnerability that can be exploited to transfer information along the network by being anonymous. Some attempts have been made using IPv4 but now since IPv6 is the new mode of network the challenge is to design it to fit the new trend.

IPv6 uses NDP (Neighbor Discovery Protocol) to find the MAC address. NDP manages interaction between nodes via message exchanges. These messages provide the data necessary for the processes of host auto configuration and packet transmission on a local link. Host auto configuration involves separate tasks of Parameter discovery, address auto configuration and duplicate address detection. Packet discovery is facilitated through router discovery process. It obtains the necessary parameters required for host configuration. Duplicate address detection is used to detect the presence of duplicate addresses on the same link. Packet transmission process requires data which can be obtained by router discovery, prefix discovery, address resolution, neighbor

The world of technology is dynamic. Technology has been revolutionized to its current status of industry four. This has seen various changes in the information technology, in the previous time the Internet Protocol 4 (IPV 4) was used to identify the IP address. Times have changes leading to the development of IPV 6 which can handle multiple addresses at a time. The IPV 6 handles 3.4 x 1038 addresses at a single time. This recommendable since the world has evolved to use of digital systems that require IP addresses every time. This paper explains the effects of technology developments, benefits and the flaws involved. The development of technology has been used in various industrial fields that include, industrial production, aquatic study, and research, smart lighting among others.

The need for IPv6 is growing by the day. There are good amount of reasons why the migration of IPv6 is not only desirable, but necessary in days to come. Some of the areas were IPv6 benefit from are reduced address space, advanced security features, enhanced quality of service, and stateless auto configuration. (IPv6 and the Future of the Internet).

Efficient and hierarchical addressing and routing infrastructure - IPv6 global addresses that are used on the IPv6 portion of the Internet are designed to create an efficient, hierarchical, and summarizable routing infrastructure that is based on the common occurrence of multiple levels of Internet service providers.

A Global transition to Internet Protocol version 6 is initiated. The government and organizations understand the benefits of this new protocol and are making change plans. The Information technology industry is undergoing a massive transformation. This research paper would outline the migration, transformation, and configuration of Internet Protocol version 6 from Internet Protocol version 4. Currently; we are close to exhausting a lot of our options regarding current Internet Protocol version 4 addresses. The new Internet

At the Internet layer there is a prerequisite of extra security solution (IPv6 features concepts and configurations)

Software defined networking is a new concept that redefined the current network device architecture and the way they behave. Due to the exponential growth of the Internet and services attached to this worldwide infrastructure, a number of issues have cropped up in modern day networks. This paper discusses a few of these limitations and how the software defined networking approach tries to alleviate them. OpenFlow, released in the year 2008, is a commercially viable implementation of this concept that is being well received by the networking industry at large. The paper also discusses the OpenFlow protocol, its implementation and the challenges facing its widespread acceptance

IPv4 and IPv6 are communication protocols (rules) which allow remote computers, servers, and other IT related devices to communicate. Both owe their existence to the massive growth of the internet. There was no need for IP-versions in 1969 when the internet began as ARPANET, a network set up by the United States Defense Advance Research Project. With only a few dozen computers on the net, each identified by a host name, they were able identify, contact and communicate with each other using host name only. When ARPANET went public and became what we know as the internet today, using host names only to identify devices became untenable.

The two TCP/IP transport layer protocols (TCP and UDP), are very crucial for the smooth operation of network services for both the computer applications and application layer protocols such as HTTP, FTP, SMTP and Telnet. These two transport layer protocols TCP and UDP execute these services via the employment of IP. They use IP in the efficient routing of packets to their respective destination networks (Steinke,2001).The TCP is further noted by Steinke (2001) to be responsible for the provision of a reliable and yet connection-oriented byte-stream packet delivery while its counterpart UDP is noted to be responsible for the provision of a connectionless but rather unreliable packet delivery. In this paper we explain the work of the two TCP/IP transport layer protocols (TCP and UDP). In addition, describe how TCP and UDP manage key functions such as reliability, port addressing, and segmentation.
