With the spread of broadband and wireless Internet access, there is a growing need for a nomadic network environment enabling the use of network services anywhere, via various access media. In a nomadic network environment, however, the connectivity is decreased because users move among different access networks, and the bandwidth is narrow and fluctuating, especially for radio propagation in wireless networks. To solve these problems, we propose a multilink system with three key functions: IPinIP tunneling, dynamic distribution of packets, and reordering of distributed packets. In particular, our dynamic distribution algorithm makes novel use of the available bandwidth estimation technique. A prototype implementation of our proposed system is evaluated, and its feasibility is discussed
