Research and Deployment Possibilities based on MIPv6
Budapest, July 5th 2007

Workshop Description
This workshop will be organized by the IST ENABLE project, a Specific Targeted Research Project funded by EU FP6 program, in collaboration with the Integrated Project Daidalos. The goal is to provide researchers, engineers and IT managers with a concentrated day on the state of the art technologies on mobility along with their security and applicability aspects. The workshop will present to the participants a comprehensive knowledge of mobility technologies and their respective benefits, and inform them about technologies developed within EU projects. It will focus in particular on the recent developments and open issues of mobile networking, its evolution to B3G/4G and advanced mobile network services.

The one-day workshop is organized in three sessions that will be based on both, invited and solicited papers. Two sessions will consist of 3 paper presentations (20 minutes each) plus one invited paper/keynote speaker (30 minutes) and the third one will consist of 2 papers (20 minutes each) plus a final panel session from researchers and industry addressing the state of the art technologies and hot topics in the area of mobility within Europe. All accepted papers will be presented and discussed. The final accepted papers will be published in a booklet being edited by the ENABLE project.

Topics
The workshop will include the presentation of the relevant work performed in FP6 projects and its implication for future research in FP7 with contributions in areas including, but not limited to:

Security and Localised Mobility support for Mobile Networks

Abstract

Nowadays, users do not only expect o have Internet access from fixed locations (e.g., at home, work, or through hotspots deployed in airports, hotels or cafes), but also from mobile platforms, such as trains or buses. Host mobility support in IP networks was a first step towards achieving such a ubiquitous Internet environment. Nevertheless, supporting the movement of a complete network that changes its point of attachment to the fixed infrastructure, without requiring the intervention of the nodes attached to the network, also presents some advantages. Additionally, access to this kind of public Internet access networks must be secured and authenticated, in order to avoid unauthorised users to gain connectivity. A third issue that needs to be tackled is the performance of the mobility management solutions deployed in these scenarios, since handover latencies should be small enough to enable the deployment of realtime applications (e.g., VoIP). The use of Localised Mobility management mechanisms aids improving this performance, while reducing the overall system signalling overhead. This paper introduces some relevant scenarios where the integration of Network Mobility, Security and Localised Mobility management mechanisms is required and proposes a solution that fulfils the requirements posed by this kind of scenarios.

Analysis of fast-reauthentication alternatives in EAP-based wireless networks

Abstract

EAP authentication in current wireless techonologies suffers from two major drawbacks that need to be addressed. First, the EAP authentication is a time consuming process, usually involving three or more rountrips to the EAP server, and it must be performed everytime the mobile node moves to a new EAP authenticator, even if the MN is already authenticated by the server and has fresh keying material. Second, this problem is aggravated by the fact that, in roaming scenarios, the EAP server is located in the home domain of the user, which is usually far away from the mobile node's current point of attachment. This paper describes the analysis of the possible alternatives to provide fast-reauthentication in eap-based wireless networks that has been done within the EU-funded project ENABLE (Enabling Efficient and Operational Mobility in Large Scale Heterogeneous IPv6 networks).

Provision of HA reliability for operational MIPv6 service deployment

Authors: Fritsche Wolfgang and Karl Mayer.

Abstract

Within the MIPv6 protocol design the Home Agent (HA) clearly plays the central role in mobility service provision, as a Mobile Node (MN) has to continuously register its current location with it. From this perspective the HA represents a single point of failure, and could cause disruption of the complete communication capability of a MN. For this purpose it is from an operational service point of view absolutely necessary to provide an appropriate reliability for the HA service.

This presentation starts with the description of a basic approach for providing HA reliability as currently discussed in the IETF mip6 Working Group, that is, explaining the roles of Active and Standby HAs, and their composition into a redundant HA set. It will then continue to describe in more detail the functionality of HA reliability, explaining the open issues and the way to address them, and going thereby beyond the IETF work by outlining how HA reliability could be integrated in a deployable MIPv6 architecture as designed by the EC funded ENABLE project.

Analysis of Options for Securing NSIS NATFW for MIPv6

Authors: Qin Wu and John Zhao

Abstract

NSIS NATFW is one client initiated firewall traversal solution that allows hosts to signal on the data path for NATs and firewalls to be configured according to the needs of the application data flows. However, securing signal for firewall traversal is one main issue. This document investigates the different options for securing NSIS NATFW with the goal of using existing credentials, user and policy databases and other security infrastructure. Transport Layer Security (TLS) with X.509 PKI, Extensible Authentication Protocol (EAP), 3GPP Generic Bootstrapping Architecture (GBA) and authorization token among these options are examined. The advantage and drawbacks of these options is evaluated.

Abstract

Daidalos II is defining a network architecture to provide ubiquitous access integrating heterogeneous access networks and providing seamless movement among them. The architecture will also support the following features:

This paper addresses the support of MANETs integration developed under the framework of Daidalos II. This architecture aims at seamlessly support nodes moving between infrastructure and ad-hoc networks, maintaining its access to the Internet with the same quality.

Mobile IPv6 deployment opportunities in next generation 3GPP networks

Abstract

In 3GPP the evolution of radio and core networks is now under study. In particular a new radio interface, called E-UTRAN (Evolved-UTRAN) is being specified to support mobile broadband peak data rates exceeding 100Mbps. In this context a new core network is also under study in the EPS (Evolved Packet System) specification. The goal of the project is to have an evolved system to offer a high bandwidth and a set of services completely based on IP.

To satisfy the needs of a mobile user this network will also need to support accesses from non-3GPP and legacy 3GPP networks (e.g. UMTS). In this context a mobility management solution is needed to guarantee session continuity when the user will roam from an access to another. In this paper we analyze the mobility management problem in 3GPP networks illustrating the adopted solutions and their open issues. Finally we provide an overview on possible future extensions.

Abstract

The increase will of ubiquitous access of the users to the requested services points towards the integration of heterogeneous networks. In this sense, a user shall be able to access its services through different access technologies, such as WLAN, Wimax, UMTS and DVB technologies, from the same or different network operators, and to seamless move between different networks with active communications.

In this paper we propose a mobility architecture able to support this users. ubiquitous access and seamless movement, while simultaneously bringing a large flexibility to access network operators

Abstract

IPv6 and Network Mobility (NEMO) support allows new usages of the Internet while on the move. This talk will focus on possible use cases of NEMO, particularly in the transportation industry with automotive, aviation, train and emergency scenarios. Some initiatives and experimentation of NEMO around the world will be overviewed and the related standardization activities at the IETF and the ISO will be emphasized.
