Figure 10-8. The Traffic Pattern after Dividing into Workgroups

A table shows the nodes included in each workgroup, the projected utilization of the workgroup, and the recommended segment bandwidth for each work- group.

The Network Performance Advisor analyzes segments that have historical traffic data exceeding a maximum threshold to determine how to create separate workgroups that would reduce utilization. The newly formed work- groups are analyzed to determine if any further division is recommended. If a newly formed workgroup does not have enough traffic to exceed a minimum threshold, it is merged back into the original segment.

N o t e	A recommendation to divide a segment is made only if the amount of traffic
	within a workgroup exceeds the amount of traffic between workgroups.
