USITS 2001 Abstract
Dynamic Host Configuration for Managing Mobility Between Public and Private Networks
Allen Miu, MIT Laboratory for Computer Science; and Paramvir Bahl, Microsoft Research
The usage and service options of a pubic network generally differ from
a private (enterprise or home) network and consequently, the two networks are
often configured differently. The existence of both types of networks motivates
our need to improve support and management of nomadic users who frequently roam
between them. We describe a solution that allows client devices to configure
themselves dynamically to adapt to the local network configuration. In addition
to supporting mobility, we describe how our solution also provides fail-over
mechanisms for providing highly available service, load balancing, and location
services. Furthermore, our solution can be used to scale networks that are
deployed in a large setting. We discuss
in detail the various issues that need to be dealt with for achieving true
device-level mobility, pointing out several unsolved problems in this area. The
algorithms and software proposed in this paper have been implemented, are
deployed, and are currently being used in a real-world public network that is
operational at the Crossroads Mall in Bellevue, Washington.
