This document specifies an updated Overlay Routable Cryptographic Hash Identifiers (ORCHID) format that obsoletes that in RFC 4843. These identifiers are intended to be used as endpoint identifiers at applications and Application Programming Interfaces (APIs) and not as identifiers for network location at the IP layer, i.e., locators. They are designed to appear as application-layer entities an...

This paper focuses on a measurement-based comparison of the handover for different mobility protocols: Mobile IPv4, Mobile IPv6 and Fast Handovers for Mobile IPv6. The paper studies the handover using active and passive measurements computing the handover latency, packet losses and the provided QoS level in a real testbed. Our experimental results show that there are severe QoS fluctuations bef...

In the face of looming IPv4 address exhaustion and the slow pace of IPv4 to IPv6 migration, this work deploys the IPv4/IPv6 translation gateway as a mechanism to ensure most of IPv6 mission critical applications to continuously interoperate with legacy IPv4 nodes. However, the existence of translation gateway between two IPSec nodes from disparate address realms imposes some incompatibility iss...

Content distribution networks have become widespread in the current IPv4-based Internet, and request-routing in CDNs today are primarily based on DNS mechanisms. This paper considers request-routing in CDNs as and when IPv6 networks begin to be deployed. Unlike IPv4, IPv6 includes explicit support for host mobility. Specifically, the functionality and mechanisms of a separate protocol, such as ...

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...

Tunneling is commonly used in several transition mechanisms. Some of the mechanisms discover the tunnel endpoint automatically by their own means. This paper describes several tunnel discovery mechanisms for IPv6 traversal beyond IPv4 legacy networks and suggests a new mechanism by which the DHCPv4 server can automatically provide configuration information about IPv6-in-IPv4 tunnel. Dual stack ...

The issues of an IPv6 stack within the today’s network are the major part of the research. IPv6 is currently being deployed in the world, and will be the Internet Protocol for at least the next fifty years. The objective of the article is to present the main Issues of IPv6 and how we tackle the new mechanisms introduced by IPv6. Finally, this paper provide some major differences between the mos...

The emerging and growing deployment of IPv6 networks will introduce cases where connectivity with IPv4 networks crossing IPv6 transit backbones is desired. This document describes a mechanism for automatic discovery and creation of IPv4-over-IPv6 tunnels via extensions to multiprotocol BGP. It is targeted at connecting islands of IPv4 networks across an IPv6-only backbone without the need for a...

The IETF Mobile IPv6 protocol has been developped to manage global (macro) mobility. It is not adapted to local (micro) mobility since it does not support any kind of hierarchy. This report presents a hierarchical protocol, built on top of Mobile IPv6, that separates local mobility (within a site) from global mobility (across sites) management. Local handoffs are managed locally and transparent...

the present universities are deploying IPv6 campus network actively, protecting the existing investment and equipment need a gradual transition process safely. In order to achieve the fast communication between IPv4 /IPv6 hybrid network, a BRT three-dimensional interchange system is proposed. By introducing kinds of technologies and communication solutions in this paper, the system is realized ...
