Each Active Directory domain controller is represented in the site topology by a server object that is associated with a specific site. Replication decisions are made based on links from this site to other sites that contain domain controllers.
Other types of services can also add server objects to the site topology. The way you can distinguish which ones are domain controllers is the presence of a NTDS Settings (nTDSDSA) object that is a child of the server object. Only domain controllers will have that object.
