Performance Analysis of IPv6 Transition Mechanisms over MPLS

 Exhaustion of current version of Internet Protocol version 4 (IPv4) addresses initiated development of next-generation Internet Protocol version 6 (IPv6). IPv6 is acknowledged to provide more address space, better address design, and greater security; however, IPv6 and IPv4 are not fully compatible. For the two protocols to coexist, various IPv6 transition mechanisms have been developed. This research will analyze a series of IPv6 transition mechanisms over the Multiprotocol Label Switching (MPLS) backbone using a simulation tool (OPNET) and will evaluate and compare their performances. The analysis will include comparing the end-to-end delay, jitter, and throughput performance metrics using tunneling mechanisms, specifically Manual Tunnel, Generic Routing Encapsulation (GRE) Tunnel, Automatic IPv4-Compatible Tunnel, and 6to4 Tunnel between Customer Edge (CE)-to-CE routers and between Provider Edge (PE)-to-PE routers. The results are then compared against 6PE, Native IPv6, and Dual Stack, all using the MPLS backbone. The traffic generated for this comparison are database access, email, File Transfer, File Print, Telnet, Video Conferencing over IP, Voice over IP, Web Browsing, and Remote Login. A statistical analysis is performed to compare the performance metrics of these mechanisms to evaluate any statistically-significant differences among them. The main objective of this research is to rank the aforementioned IPv6 transition mechanism and identify the superior mechanism(s) that offer lowest delay, lowest jitter, and highest throughput

Mobile IP: state of the art report

Due to roaming, a mobile device may change its network attachment each time it moves to a new link. This might cause a disruption for the Internet data packets that have to reach the mobile node. Mobile IP is a protocol, developed by the Mobile IP Internet Engineering Task Force (IETF) working group, that is able to inform the network about this change in network attachment such that the Internet data packets will be delivered in a seamless way to the new point of attachment. This document presents current developments and research activities in the Mobile IP area

Design and Experimental Evaluation of a Route Optimisation Solution for NEMO

An important requirement for Internet protocol (IP) networks to achieve the aim of ubiquitous connectivity is network mobility (NEMO). With NEMO support we can provide Internet access from mobile platforms, such as public transportation vehicles, to normal nodes that do not need to implement any special mobility protocol. The NEMO basic support protocol has been proposed in the IETF as a first solution to this problem, but this solution has severe performance limitations. This paper presents MIRON: Mobile IPv6 route optimization for NEMO, an approach to the problem of NEMO support that overcomes the limitations of the basic solution by combining two different modes of operation: a Proxy-MR and an address delegation with built-in routing mechanisms. This paper describes the design and rationale of the solution, with an experimental validation and performance evaluation based on an implementation.Publicad

Analysis of IPv6 through Implementation of Transition Technologies and Security attacks

IPv6 provides more address space, improved address design, and greater security than IPv4. Different transition mechanisms can be used to migrate from IPv4 to IPv6 which includes dual stack networks, tunnels and translation technologies. Within all of this, network security is an essential element and therefore requires special attention. This paper analyses two transition technologies which are dual stack and tunnel. Both technologies are implemented using Cisco Packet Tracer and GNS3. This work will also analyse the security issues of IPv6 to outline the most common vulnerabilities and security issues during the transition. Finally, the authors will design and implement the dual stack, automatic and manual tunnelling transition mechanisms using Riverbed Modeler simulation tool to analyse the performance and compare with the native IPv4 and IPv6 networks

Reducing Packet Overhead in Mobile IPv6

Common Mobile IPv6 mechanisms, Bidirectional tunneling and Route optimization, show inefficient packet overhead when both nodes are mobile. Researchers have proposed methods to reduce packet overhead regarding to maintain compatible with standard mechanisms. In this paper, three mechanisms in Mobile IPv6 are discussed to show their efficiency and performance. Following discussion, a new mechanism called Improved Tunneling-based Route Optimization is proposed and due to performance analysis, it is shown that proposed mechanism has less overhead comparing to common mechanisms. Analytical results indicate that Improved Tunneling-based Route Optimization transmits more payloads due to send packets with less overhead

Performance analysis of tunnel broker through open virtual private network

Tunnel Broker uses automatic configuration tunneling mechanism for IPv6 clients connected to IPv4 internet. Connectivity between clients and service providers in IPv6 is urgently needed. Open VPN as a provider implemented configures it by a VPN network, so IPv6 and IPv4 public IP clients can easily connect to the server. In this research focused on the performance of tunnel broker mechanism by utilizing open VPN as access to the network. IPv6 tunnel broker is developed by installing Open VPN and providing IPv6 IPs. Implementation of public IP usage in observing the performance of tunnel broker development is done in BCN Telkom Laboratory Network. The measurement results show that TCP and UDP throughput of IPv6 is slightly higher than IPv4. The research using OpenVPN as a server Tunnel Broker for client access to the server is still rarely done, especially in the field of the network based on Internet Protocol
