A pool contains load balanced servers. You can define multiple servers for a pool. Each LBDN must have at least one pool associated with it to be operational. For sites with a large amount of incoming traffic, you can configure DNS Traffic Control to distribute client requests to multiple servers using a load balancing pool. An individual server can belong to one or multiple load balancing pools, depending on how you want to manage your network traffic. You can also set the order of servers in the pool and define a ratio on a server basis.
A pool can contain preferred and alternative load balancing methods. You can define permissions on these pools and associate extensible attributes with them. Each pool can contain one or more health monitors associated with it. You can define TTLs at the LBDN level. These TTLs are valid for dynamic RRsets that are created by the querying process for each query.
