Reorganize Your Current Equipment

Recommendation Details Section

The Recommendation Details section of the report supplies the supporting information for the recommendations made by the Network Performance Advisor. It includes a textual explanation and the “before” and “after” graph- ical representations of the affected network. The recommendations are in priority order, starting with High Priority.

A “before” representation of the network might look like the following figure:

Figure 10-5. The traffic pattern before implementing reorganization recommendations

In this situation, the node chris.rose.hp.com communicates most frequently with nodes on another segment. Network utilization can be improved by moving chris.rose.hp.com to the switch segment 10.4.12.10::B3. This is a High Priority recommendation because it will significantly decrease network utilization for switch segment 10.4.12.10::B4.

The “after” representation would look like the following figure:
