Netscape DIRECTORY SERVER 6.0 - DEPLOYMENT Deployment Manual page 165

Each locality contains two suppliers, which share master copies of the data for that
site. Each locality is therefore responsible for the master copy of its own data.
Using a multi-master architecture ensures the availability of the data and helps
balance the load of work managed by each supplier server.
To reduce the risk of total failure,
read-write master directory servers at each site.
The following diagram illustrates the interaction between the two supplier servers
in Europe and the two supplier servers in the US:
