A WAN Traffic Policy is a set of rules that control the generation of NDS traffic.
A policy is text stored as an NDS property value on the Server object, the LAN Area object, or both. The policy is interpreted according to a simple processing language.
The property in which this text is stored is Wanman: Wan Policy. Multiple policies are handled as multiple values of this property.
Predefined policy groups are distributed with WAN Traffic Manager. You can use these policies as they are, you can modify these policies, or you can write new policies.
You create or apply policies from the WAN Policies page of the Server object or of the LAN Area object.
You can apply policies to individual servers or you can create LAN Area objects and assign several servers to one of these objects. Any policy that is then applied to the LAN Area object is automatically applied to all servers that are assigned to the object.
