Sample configurations

Two-level unicast

About two-level unicast

In this configuration, multiple branch offices in a non-multicast corporate WAN share the same ISP line.

ContentDirector conserves bandwidth by using one transport group leader for the entire WAN. Data is transmitted over the Internet only once, then distributed within the WAN via unicast from the group leader to the group members.

This configuration assumes that the core application is not resident within the corporate WAN. If the core application is within the WAN, it is probably more efficient to use one-level unicast.

Configuring transport group members for two-level unicast
