This scenario is similar to the central publisher scenario, except that separate computers perform the publication and distribution tasks. This is useful when the publication server¾for example, a heavily used online transaction processing (OLTP) server¾should be freed from the distribution role because of performance and storage space considerations. The publication server must be connected to the distribution server by a reliable, high-speed communications link.
For information about implementing this scenario, see Chapter 14, Setting Up Replication.
