For server sites distributed over a city, a country, or even the world,
Eddie's Enhanced DNS allows the entire distributed web
server capacity to be usable. The individual sites may have different numbers
of servers, different vintages of computer, even different operating systems.
The load information passed between servers at a site is processed locally
and summary information passed to each Eddie Enhanced DNS
server, across the Internet if necessary.
The Eddie Enhanced Domain Name Service package dynamically
balances client domain name resolution requests across all sites in the
distributed server, and more specifically, across each Front End
within each site. The balancing is performed to keep each site
working at approximately the same fraction of its overall capacity,
rather than equalising the number of requests sent to each site, as
occurs with Round Robin based schemes.
This ensures maximum efficiency of Front End Server resources within
each site.
