Understanding Originating Writes

Replication of objects between DCs is accomplished through the use of a property known as originating writes. As changes are made to an object, this property is incrementally increased in value. A DC compares its own version of this value with the one received during a replication request. If it is lower, the change is applied; if not, it is discarded. This simple approach to replication is also extremely reliable and efficient and allows for effective object synchronization. For more information about replication, including a detailed analysis of originating writes and its other key components, see Chapter 7.
