You can use the Sun OpenDS Standard Edition proxy to route requests across multiple data sources or LDAP servers. These LDAP servers must be replicated in order to contain identical data.
When using the Sun OpenDS Standard Edition proxy, the client requests are routed to one of the data sources based on the load balancing algorithm set.
You can choose one of the following load balancing algorithms:
Proportional. All the LDAP servers handle requests, based on the proportions (weight) set.
Failover. There is one main LDAP server that handles all requests, until there is a failure.
Saturation. There is one main LDAP server that handles all requests, until a saturation limit is reached.
