Internetworking for Mobile Computers

互联网软件允许连接到物理上不同的数据网络的计算机相互通信。最近便携式计算机的出现表明，很快就会有相当大一部分计算机能够并将会移动。由于目前的计算机很少移动，因此需要采用新的方法实现互联网互连。本研究探讨如何扩展现有的网际网络协议以支持移动计算机。该方法结合了转发、组播、地址重新分配和链路级技术。结果将是一套协议，用于地区发现、动态地址分配、转发链的建立和销毁，以及向更高级别的协议通知地区的变化。这项工作将通过在IP互连软件中模拟和示范实施他们的想法来进行评估。

Internetworking software allows computers attached to physically distinct data networks to communicate with one another. The recent advent of portable computers suggest that soon a substantial fraction of all computers can and will move. Because present computers rarely move, new approaches to internetworking are required. This research investigates how to extend present internetworking protocols to support mobile computers. The approach is a combination of forwarding, multicasting, address reassignment, and link-level techniques. The results will be a suite of protocols for locale discovery, dynamic address assignment, establishment and destruction of forwarding chains, and notification to higher-level protocols of a change of locale. The work will be evaluated via simulation and demonstration implementation of their ideas within IP internetworking software.
