LANs Connected by WAN Links

The rules outlined for extended LANs that use bridges also apply to LANs that are connected by WAN links. Each LAN in such a network is a separate entity, so several DTS servers must be configured on all of the LANs. Configure each LAN according to the following guidelines:

· Configure at least three DTS servers on each LAN.

· Configure at least one server on each LAN as a courier.

· Configure at least one global server on each LAN.

· If you are using time-providers, install them at the global servers.

These recommendations lead to higher DTS efficiency and availability despite the irregular delays that are associated with WAN links.
