Solutions and Research Directions
–solutions addressing mobility:
nflexible directory services to enable mobile to
find location-dependent services, often based on “shopping” or
negotiation:
–scaleable, fault-tolerant architecture (exploit
communication locality, replicate directory data, weakened
consistency semantics: allow directory info to go stale as long
as we can improve on suboptimal routes during connection)
–brokerage service (e.g.: trading in ODP)
–accounting
service: mediate cost accounting between mobile client and
servers
–rebindable service interfaces (switch service providers
“on-line”)
nubiquitous security and authentication (IPv6
will go a long way towards providing this goal)
