This document specifies the operation of mobile computers using IPv6. Each mobile node is always identified by its home address, regardless of its current point of attachment to the Internet. While situated away from its home, a mobile node is also associated with a care-of address, which provides information about the mobile node’s current location. IPv6 packets addressed to a mobile node’s ho...

Although Mobile IPv6 allows maintaining transport layer connections alive when an IPv6 node roams to different access networks, certain enabling mechanisms are needed for it to work in large scale network scenarios, including, most notably, issues with Mobile IPv6 bootstrapping and firewall traversal. This paper tries to address these problems by extending the IETF PANA and NSIS protocols to fo...

USAGI Project [8] has improved Linux IPv6 [1] stack. IPv6 IPsec is one of the products of our efforts. Linux IPsec [6] stack is implemented based on XFRM architecture which is introduced in linux-2.5. We design and implement Mobile IPv6 (MIPv6) [4] Stack on the architecture. MIPv6 uses IPsec for its secure signaling. Accordingly IPv6 IPsec and MIPv6 closely cooperate each other. In this paper w...

This document lists security threats related to IPv6 multihoming. Multihoming can introduce new opportunities to redirect packets to different, unintended IP addresses. The intent is to look at how IPv6 multihoming solutions might make the Internet less secure; we examine threats that are inherent to all IPv6 multihoming solutions rather than study any specific proposed solution. The threats in...

This document specifies a method for connecting IPv6 hosts and routers (nodes) within predominantly IPv4-based sites. This method is based on an IPv6-IPv4 compatibility aggregatable global unicast address format (described herein) that embeds the IPv4 address of a node within the EUI-64 format interface identifier of an IPv6 address. This document assumes that, during the IPv4 to IPv6 coexisten...

Adoption of IPv6 technology has been accelerated in the last few years but there is limited experience in the deployment of Quality of Service (QoS) for IPv6 traffic in backbone networks. As available software and hardware is designed to handle IPv4 packets, there is a need to accurately measure the performance of QoS mechanisms in an IPv6 environment. This paper discusses tests in the deployme...

Since IPv6 has more benefits over IPv4, the development and deployment of the IPv6 protocol-based products are currently taking place and the migration of IPv4 to IPv6 has also been steadily happen. In these mixed network environment, Network management for both IPv4 and IPv6 is a serious issue. In this paper, we focus on the design and implementation of an active measurement system which can b...

IPv6 is a network layer protocol of the OSI reference model. IPv6 uses the Neighbor Discovery Protocol (NDP) that works on link local scope of IPv6 network. NDP covers host initialization and address auto configuration that is one of IPv6 advantages and other important functionalities. IPv6 mandates to support Internet Protocol Security (IPSec) for end‐to‐end communication security. However, th...

In this article we analyze IPv6 handover over wireless LAN. Mobile IPv6 is designed to manage mobile nodes’ movements between wireless IPv6 networks. Nevertheless, the active communications of a mobile node are interrupted until the handover completes. Therefore, several extensions to Mobile IPv6 have been proposed to reduce the handover latency and the number of lost packets. We describe two o...

This document specifies an intra-site automatic tunneling protocol (ISATAP) for connecting IPv6 hosts and routers (nodes) within predominantly IPv4-based networks. This method is based on an IPv6 aggregatable global unicast address format (described herein) that embeds the IPv4 address of a node within the EUI-64 format interface identifier. This document assumes that, during the IPv4 to IPv6 c...
