Sun Java System Directory Server Enterprise Edition 6.3 Deployment Planning Guide

Directory Proxy Server and Availability

With features such as configurable load balancing, failover, and failback, Directory Proxy Server ensures that systems have access to required data.

Directory Proxy Server works with Directory Server to ensure reliability and to protect against denial-of-service attacks. Directory Proxy Server automatically routes requests appropriately and provides secure firewall-like services for Directory Server.

To prevent a single point of failure for mission-critical applications, Directory Proxy Server detects outages and routes traffic around affected areas, effectively load balancing requests across systems. When the affected areas are restored to operation, Directory Proxy Server detects the restored servers automatically.
