Understanding tradeoffs in incremental deployment of new network architectures

Despite the plethora of incremental deployment mechanisms proposed, rapid adoption of new network-layer protocols and architectures remains difficult as reflected by the widespread lack of IPv6 traffic on the Internet. We show that all de-ployment mechanisms must address four key questions: How to select an egress from the source network, how to select an ingress into the destination network, how to reach that egress, and how to reach that ingress. By creating a de-sign space that maps all existing mechanisms by how they answer these questions, we identify the lack of existing mech-anisms in part of this design space and propose two novel approaches: the “4ID ” and the “Smart 4ID”. The 4ID mech-anism utilizes new data plane technology to flexibly decide when to encapsulate packets at forwarding time. The Smart 4ID mechanism additionally adopts an SDN-style control plane to intelligently pick ingress/egress pairs based on a wider view of the local network. We implement these mech-anisms along with two widely used IPv6 deployment mech-anisms and conduct wide-area deployment experiments over PlanetLab. We conclude that Smart 4ID provide better overall performance and failure semantics, and that inno-vations in the data plane and control plane enable straight-forward incremental deployment

Effectiveness of security tools to anomalies on tunneled traffic

Tunneling mechanism has been proven as an option to link the communication between IPv6 networks and IPv4 environments without incurring the high costs of upgrading equipment. However, this mechanism has reduced the network performance and downgrade the level of security if compared to the native IPv6 network. The Transition Mechanism has also become a covert channel for spreading threats without being acknowledged by the network security tools. Even though the issue has been raised in the set of IETF rules, still they do not provide any recommendation to overcome the problem. Based on this reason, this study explored the effectiveness of conventional network security tools to detect any anomalies occurring on a tunneling mechanism especially against packet flooding attack in IPv6 tunneling. In order to achieve this objective, a testbed that has been deployed with conventional firewall and IDS is used to simulate the IPv6 to IPv4 tunneling mechanism, several network attacks are then launched and the network traffic is then captured to be analyzed. The result shows that the firewall with the default settings had blocked all the tunneling packets, while the firewall and IDS with the default rule of set had performed well in IPv4 but not in the IPv6 tunnel

Técnicas para el despliegue de IPv6 en redes LAN

El crecimiento de Internet registrado a lo largo de los, aproximadamente, últimos 20 años trajo consigo el problema del agotamiento de las direcciones IPv4 (Internet Protocol versión 4). Como solución a este problema, el IETF (Internet Engineering Task Force) propuso la adopción de un nuevo protocolo al que se denominó IPv6 (Internet Protocolo versión 6). Lentamente, desde hace varios años, IPv6 está reemplazando a IPv4 en Internet mediante la aplicación de variadas técnicas de transición. Hoy coexisten en Internet ambos protocolos. El avance del despliegue de IPv6 en Internet no es uniforme a nivel mundial y existen regiones en las cuales todavía este no es importante. Este es el caso de la Argentina. Este trabajo tiene como propósito principal aportar información que facilite e incentive el despliegue de IPv6 en redes de área local (LAN – Local Area Network) como forma de mejorar la penetración del nuevo protocolo tanto en ámbitos académicos, pequeñas organizaciones en general y en el hogar. La poca comprensión del nuevo protocolo y su tardía adopción en nuestras redes podría traer como consecuencia elevados costos derivados de apresurados despliegues y, en el peor de los casos, pérdidas de conectividad a sitios de Internet que solo operen con IPv6.Eje: Arquitecturas, Redes y Sistemas Operativos.Red de Universidades con Carreras en Informátic

Migration cost optimization for service provider legacy network migration to software-defined IPv6 network

This is the peer reviewed version of the following article: Dawadi, BR, Rawat, DB, Joshi, SR, Manzoni, P, Keitsch, MM. Migration cost optimization for service provider legacy network migration to software-defined IPv6 network. Int J Network Mgmt. 2021; 31:e2145, which has been published in final form at https://doi.org/10.1002/nem.2145. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.[EN] This paper studies a problem for seamless migration of legacy networks of Internet service providers to a software-defined networking (SDN)-based architecture along with the transition to the full adoption of the Internet protocol version 6 (IPv6) connectivity. Migration of currently running legacy IPv4 networks into such new approaches requires either upgrades or replacement of existing networking devices and technologies that are actively operating. The joint migration to SDN and IPv6 network is considered to be vital in terms of migration cost optimization, skilled human resource management, and other critical factors. In this work, we first present the approaches of SDN and IPv6 migration in service providers' networks. Then, we present the common concerns of IPv6 and SDN migration with joint transition strategies so that the cost associated with joint migration is minimized to lower than that of the individual migration. For the incremental adoption of software-defined IPv6 (SoDIP6) network with optimum migration cost, a greedy algorithm is proposed based on optimal path and the customer priority. Simulation and empirical analysis show that a unified transition planning to SoDIP6 network results in lower migration cost.U.S. National Science Foundation (NSF), Grant/Award Number: CNS 1650831 and HRD 1828811; ERASMUS+ KA107; Nepal Academy of Science and Technology (NAST); Norwegian University of Science and Technology; University Grant Commission (UGC), Nepal, Grant/Award Number: FRG/74_75/Engg-1Dawadi, BR.; Rawat, DB.; Joshi, SR.; Manzoni, P.; Keitsch, MM.

Migration to a New Internet Protocol in Operator Network

This thesis explains the differences between IPv4 and IPv6. Another important part of the thesis is to review the current readiness of IPv6 for worldwide production use. The status (in terms of readiness, adaptability, compatibility and co-existence) of IPv6 in TeliaSonera is discussed in more detail. The most important reason for migrating to IPv6 is the address exhaustion of IPv4. This may not be a big problem in the developed countries but in developing countries the growth of Internet is fast and lots of more addresses are needed. The need for addresses is not only from computers but from many devices connected to the Internet. Attempts to slow down the exhaustion of free addresses have been made but current solutions are not enough. IPv6 will solve the problem by using much longer addresses. It will also add security features and simplify headers to speed up routing. TeliaSonera has started to roll out IPv6 services. At the beginning the corporate customers will receive IPv6 connectivity and consumers will follow later. TeliaSonera International Carrier is already serving its customers with IPv6. It seems that IPv6 is ready, standards have been ready for years and support in devices and software is prevalent. To achieve and keep up the global connectivity, IPv6 is a must and should not be avoided

Etude comparative des mécanismes de transition de l’IPv4 à l’IPv6

Actuellement le concept de la transition de l'IPv4 à l'IPv6 est largement étudié pour faciliter le déploiement de l'IPv6. IPv4 et IPv6 sont deux protocoles incompatibles. En outre l'infrastructure réseau actuellement et la majorité des services internet sont disponibles sur IPv4, et par conséquent, il est impossible de migrer de l'IPv4 à l'IPv6 en un jour. IPv4 et IPv6 doivent coexister pendant une longue période et le déploiement de l'IPv6 ne peut se faire que progressivement. Plusieurs mécanismes de transition ont été développés et peuvent être utilisés pour cette raison. Dans cet article nous allons présenter une étude comparative approfondie des mécanismes de transition de l’IPv4 à l’IPv6 que nous avons classé en 3 familles : pour chacune d’entre elles nous allons décrire les mécanismes concernés, leurs principes de fonctionnement, leurs domaines d’utilisations, leurs avantages et leurs inconvénients. Ce travail n'est pas seulement destiné à établir la comparaison entre les différents mécanismes de transition mais également pour pouvoir choisir le mécanisme de transition le plus convenable en fonction des exigences et des besoins particuliers des utilisateurs
