Summary: 
Technologies to access remote devices from mobile computers over network are drawing attentions. Nowadays, growth of wireless and hot-pluggable devices causes a new problem: dynamic change of network configuration such as an IP address change and device connective configurations such as a device migration. We propose a system called "NextD" which makes it easy to cope with such problems while keeping conventional APIs intact. NextD allows applications to access remote devices in exactly the same way as they access local devices, through device file interface. NextD supports a host migration and a device migration enable application to continue accessing to remote devices. This paper describes design and implementation of NextD. We have implemented a prototype system on Linux OS. Experimental results show that required features are naturally supported and the overhead of the proposed system is small enough for actual use.
