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.
