Abstract.
This paper addresses the issue of defining
a location service suitable for very dynamic and highly populated networks
(millions of users), where services might experience highly correlated
peaks of traffic or synchronized access to specific servers. A cooperative
mobile agent solution is proposed to solve the major problems, allowing
the dynamic deployment of new application servers when needed. But it requires
an adequate location service to route the clients to the application servers,
which scales to a large number of clients and still allows a high number
of updates. This paper presents a very dynamic location service, which
adapts to overload situations by modifying the routing information distribution
and (possibly) its servers’ internal structure. The responsive and fast
route update results in a load re-distribution, which allows it to scale
to a broader range compared to other alternative approaches.
