Setting Up Parallel Propagation

In most cases, the master KDC is used exclusively to propagate its database to the slave KDCs. However, if your site has a lot of slave KDCs, you might want to consider load-sharing the propagation process, known as parallel propagation.

Parallel propagation allows specific slave KDCs to share the propagation duties with the master KDC. This enables the propagation to be done faster and to lighten the work for the master KDC.

For example, say your site has one master and six slaves (shown in Figure 3-2), where slave-1 through slave-3 consist of one logical grouping and slave-4 through slave-6 consist of the other. To set up parallel propagation, you could have the master KDC propagate the database to slave-1 and slave-4, and those slaves could in turn propagate the database to the slaves in their group.
