Replication

The success of the AD infrastructure largely depends on healthy replication. Every domain controller in the network should be aware of every change in configuration. When a domain controller triggers a sync, it passes the data through the physical network to the destination. It consumes the bandwidth of the wire for the data. Depending on the used media and available bandwidth, the impact made by this replication traffic will vary. If it has high-speed links, such as 40 Gbps, 10 Gbps, 1 Gbps, or 100 Mbps, then the impact made by replication traffic will be very low. But in slow links, such as 128 Kbps or 256 Kbps, the impact will be significantly higher.

Most of the time, links between remote networks are slow links and come with ...
