NEMO: Network Mobility in IPv6 (NEMO: movilidad de redes en IPv6)

Also published in Spanish in: "Novática. Revista de la Asociación de Técnicos de Informática", n. 174, March-April 2005, p. 37-43.Nowadays, users request Internet access in more and more heterogeneous scenarios. In particular a need to access the Internet from mobile platforms, like trains, buses or planes, has appeared. A new working group has been formed within the IETF (Internet Engineering Task Force) NEMO WG (NEtwork MObility Working Group) whose main goal is to provide mechanisms allowing the management of the mobility of a network as a whole, enabling that network to change its point of attachment to an IP-based (Internet Protocol) fixed infrastructure without disrupting ongoing communications. This article describes the IPv6 (Internet Protocol version 6) network mobility basic support solution defined by the NEMO WG, analysing its limitations. In addition, some of the contributions to the network mobility research area developed within the framework of the European project DAIDALOS (Designing Advanced network Interfaces for the Delivery and Administration of Location independent, Optimised personal Services) are presented
