Conference Paper

A Study on Comparison and Contrast between IPv6 and IPv4 Feature Sets.

In proceeding of: International Conference on Computer Networks and Security (ICCNS-2008)

ABSTRACT This document provides an analysis and comparison
of IPv4 and IPv6 under various circumstances. It is well
understood that IPv6 has been designed to replace IPv4. We have
done a feature-by-feature comparison and contrast of IPv6 versus
IPv4 and found that IPv6 offers many unique opportunities for
increasing a network architectures efficiency and agility. In some
sense, there is a competition going on between these protocols, as
they are not directly compatible, and network providers and users
are being forced to determine whether to support one or both
protocols for various network services. The new version of IP,(i.e.
IPv6), constitutes an effort to overcome the inborn limitations of
IPv4, in order for the new protocol be able to respond to the new
needs as they shape today in the Internet. This paper is aimed to
discuss about various comparison issues when porting an IPv4
application to IPv6 with focus on issues that an application
developer would face rather than a complete API reference.IPv4 is
the incumbent and currently has the most widespread usage for
conventional Internet applications.IPv6 is a large-scale re-design
and re-engineering of IPv4, based on many lessons learned as the
IPv4-based Internet grew and was used in unforeseen ways

    ABSTRACT: Already several approaches for supporting QoS in best effort IP networks have been developed and described in research papers and articles, projects could demonstrate their viability in the context of IPv4 networks. In an internet we know that packet delay and loss are the two important parameters of IPv6 QoS metrics.The first step for the QoS experiments was to decide upon the tests would be performed what traffic metrics would be used to evaluate them. In this paper we actually compare IPv6 and IPv4 QoS metric issues like jitter, delay, loss performance and path and tunnel discovery.This paper presents and discuss the measurement methodologies and show that IPv6 paths have a more delay and loss performance than their IPv4 counter parts.

    ABSTRACT: Deploying the next generation Internet protocol (IPv6) over Fibre is facing an important challenge as the Fibre standard is failing to support IPv6 functionalities. In fact unlike the other standards Fibre optic links is based on how to reduce the over head in terms of header processing at data link layer by removing CRC field and Transport layer in IPv6 packet format. As a result the IPv6 packets over Fibre optic links standard shows that error handling can be performed at the network layer of ISO/OSI model instead of Data link layer and Transport layer. As a result our simulation results shows that error handling using IPv6 extension header at network layer has a smaller packer processing time as compared to error handling at data link layer and Transport layer in ISO/OSI. In this paper, we present different architectures to consider when deploying IPv6 packets over Fibre such as FIPv6.Also we point out challenges and solutions related to this deployment by focusing particularly on the role of FIPv6 impact on hardware and software, network layer error handling issues, challenges, facts etc.

    ABSTRACT: The Internet protocol was started in early 1980.In the earlys1990’s the Internet was growing some temporary solutions were offered in order to cover the fast growth in number of Internet user’s such as Network address translation (NAT), CIDR (Classless Inter domain Routing).At the Same time IETF began working to develop a new Internet Protocol namely IPv6 which was designed to be a Successor to the IPv4 Protocol. This paper proposes the new concept of error handling at network layer (layer-3) instead of data link layer (layer-2) in ISO/OSI reference model by adopting new capabilities and by using IPv6 over Fiber. This paper also shows how to reduce the over head In terms of header processing at data link layer by eliminating cyclic redundancy check (CRC) field by using IPv6 over Fiber. Therefore we can also prove that ISO/OSI model contains 6 layers instead of 7 layers.
