Abstract. In the future Wireless Internet, mobile nodes will be able to choose
between providers offering competing services at a much finer granularity than
we find today. Rather than months, service contracts may span hours or minutes.
Connectivity, however, is just one of many possible services. Providers will begin to
offer network and application-level services targeted at improving the overall wireless
experience of the user. Determining the best path through the various networks will
require accurate information describing which services are being offered by each
provider. In this paper, we model the process of propagating this information as an
instance of a distributed, hierarchical cache. Access routers actively discover and
