Mobile IPv6 (MIPv6) is one of the most mature and widely accepted technologies for mobility support in IPv6 networks. In MIPv6, home agent acts as the anchor points of mobile nodes and is responsible for receiving data packets on behalf of them and tunneling the packets to the current points of attachment of the mobile nodes in the Internet. Two problems existing in the current MIPv6 scheme motivate the study of this paper. First, we do not have any proper load sharing mechanism for multiple HA deployment. Second, Home Agent failure detection in MIPv6 is very slow and there is no specified failure recovery mechanism.In this paper 1 we propose a mechanism to address the above mentioned problems of load sharing and failure recovery while trying to reduce the time of home agent failure detection and recovery. We will present simulation results to demonstrate that our solution can fairly distribute loads among multiple home agents.

Abstract. This paper describes the practical implementation of a federated health record server based on a generic and comprehensive architecture, deployed in a live clinical setting and accessed from wireless and IPv6 network test-beds. The authors, working at the Centre for Health Informatics and Multiprofessional Education (University College London), have built up over twelve years of experience within Europe on the requirements and information models that are needed to underpin comprehensive multi-professional electronic health records. The UCL federated health record server is running in the Department of Cardiovascular Medicine at the Whittington Hospital in north London. Through the EU 6WINIT project this infrastructure has been modified to enable secure wireless access via IPv6.

The Silk network is a VSAT-based network connecting a number of NRENs in Central Asia and the Caucasus into the Internet. While most of the network uses IPv4, this paper discusses how it was possible to provide native IPv6 facilities onto the Network. Our initial experiences with that system are described.
