Wireless technologies are rapidly evolving and the users are demanding the possibility of changing its point of attachment to the Internet (i.e Access Router) without breaking the IP communications. This can be achieved by using Mobile IPv6. However mobile clients must forwards its data packets addressed towards its home network through a special entity, the Home Agent (HA). This HA is a key point when considering the performance of Mobile IPv6-based networks.

The Home Agent (HA) is a key point when
considering the performance of Mobile IPv6-based networks. This paper presents the first steps towards characterizing the load of a HA. This may be useful both for researchers that aim to propose novel architectures that improve the performance of the HAs and for ISPs willing to deploy Mobile IPv6. To achieve our goals first
we analyzed the internal traffic of a medium-size department. Then we reviewed the existing models and we evaluated their applicability to this particular scenario. Our results showed that the estimated load of a HA serving a medium-size department (around 1500 hosts) is high with a maximum throughput of 262 Mbps.

AgentLink III is proposed as a follow-on to AgentLink II, the IST-funded Network of Excellence for agent-based systems established in August 2000. Agent-based systems are one of the most vibrant and important areas of research and development to have emerged in information technology in the 1990s, and underpin many aspects of the broader IST FP6.
Many observers believe that agents represent the most important new paradigm for software development since object-orientation. An agent is a computer system that is capable of flexible autonomous action in dynamic, unpredictable, typically multi-agent domains. Some application domains where agent technologies will play a crucial role include: Ambient Intelligence, the seamless delivery of ubiquitous computing, continuous communications and intelligent user interfaces to consumer and industrial devices; Grid Computing, where multi-agent system approaches will enable efficient use of the resources of high-performance computing infrastructure in science, engineering, medical and commercial applications; Electronic Business, where agent-based approaches are already supporting the automation and semi-automation of information-gathering activities and purchase transactions over the Internet; the Semantic Web, where agents are needed both to provide services, and to make best use of the resources available; Bioinformatics, where intelligent agents may support the coherent exploitation of the data revolution occurring in biology; and others including monitoring and control, resource management, and space, military and manufacturing applications, for example.
AgentLink III will act as a unifying focus for agent-based activities in these different domains. As with AgentLink and AgentLink II, the long-term goal of AgentLink III is to put Europe at the leading edge of international competitiveness in this increasingly important area.
