http://en.wikipedia.org/wiki/Active_Directory see the topic replication.

The Knowledge Consistency Checker is a built-in process that runs on all domain controllers and generates replication topology for the Active Directory forest. The KCC creates separate replication topologies depending on whether replication is occurring within a site (intrasite) or between sites (intersite). The KCC also dynamically adjusts the topology to accommodate new domain controllers, domain controllers moved to and from sites, changing costs and schedules, and domain controllers that are temporarily unavailable http://technet.microsoft.com/en-us/library/cc756899(v=ws.10).aspx

Hello, Please see this article about how Active Directory Replication Topology Works: http://technet.microsoft.com/en-us/library/cc755994%28v=WS.10%29.aspx There is a part about KCC and Topology Generation.
