Distributed Director works great when used in conjunction with Local
Directors spread across multiple sites. When deploying DD bear in mind that
the DD merely determines the best server (webfarm) that can service the
client, based on configurable parameters, then returns the IP address of the
server to the client.
This means that the DD is authoritative over the subdomain (www.abc.com).
The primary DNS server for abc.com needs to have an NS entry in its zone
file for the DD.
I guess the most important part of the deployment is how the DD determines
the best server. It can use feedback from edge routers (DFP) to determine
the server closest to the client. This is quite sophisticated, and can
include BGP attributes (such as AS-Path), and RTT.
Hope this helps.
