Design, Implementation, and Evaluation of Virtual Internet Protocol

چکیده
Miniaturization and increasing portability of computers will require users in the future to access the network regardless of location. In such an environment, host migration transparency will be an essential feature of wide area networks. In order to achieve host migration transparency, we introduced the concept of virtual network and the propagating cache method [7]. As an example of a virtual network protocol, we also proposed Virtual Internet Protocol (VIP). This paper describes the details of the design and implementation of VIP. We implement VIP by modifying a 4.3BSD-based operating system kernel. This paper also compares the overhead of VIP to that of IP. Measured results indicate that VIP can achieve host migration transparency in the Internet with negligible overhead.
