Although site design is relatively independent from domain structure, the replication topology depends on how available domain controllers are and how they are configured. The KCC running on each domain controller monitors domain controller availability and configuration, and it updates replication topology as changes occur. The designated ISTG in a site performs similar monitoring to determine the best way to configure intersite replication. This means that as you implement or change the domain controller configuration, you will change the replication topology.
To develop or revise a site design, you should do the following:
Map your network structure and then map this structure to site structure.
Design your sites and ...
