| Configuring the WSM using Device Manager |
|
The Internet name registry has become so large that a single server cannot keep track of all the entries. This is resolved by splitting the registry and saving it on different servers. If you have large DNS server farms, the WSM lets you load balance traffic based on DNS names. To load balance DNS names, the host name is extracted from the query, processed by the regular expressions engine, and the request is sent to the real server.
The following figure shows a DNS server farm load balancing DNS queries based on DNS names. Requests having DNS names that begin with A through G go to Server 1; DNS names that begin with H through M go to Server 2; DNS names that begin with N through T go to Server 3; DNS names that begin with U through Z go to Server 4.
