Figure 8-2 Multi-Master Replication - Netscape DIRECTORY SERVER 6.1 - ADMINISTRATOR Administrator's Manual

Replication Scenarios
This type of configuration can work with any number of consumer servers. Each
consumer server holds a read-only replica. The consumers can receive updates
from both suppliers. The consumers also have referrals defined for both suppliers
which are used to forward any update requests that they receive. Such scenarios
are called multi-master configurations.
Figure 8-2 shows an example of multi-master replication scenario.
Figure 8-2
Multi-master configurations have the following advantages:
• Automatic write failover when one supplier is inaccessible
• Updates are made on a local supplier in a geographically distributed
environment

Multi-Master Replication
Replication, especially multi-master replication, works better over
high speed links than over slow links such as a WAN used in
geographically distributed environments.
