About the Bandwidth Optimization report
The Bandwidth Optimization report summarizes the overall inbound and outbound bandwidth improvements for your network. You can create reports according to the time period, of your choice, application, and type of traffic.
The values in the data reduction graph of the Bandwidth Optimization report for WAN and LAN Throughput are divided by 1000 rather than 1024. Thus, the calculated values for data reduction will be slightly higher than you might expect.
The Bandwidth Optimization report includes these statistics that describe bandwidth activity for the time period you specify:
Data Reduction% displays the peak and total decrease of data transmitted over the WAN, according to this calculation:
(Data In – Data Out)/(Data In)
It displays the capacity increase x-factor below the peak and total data reduction percentages.
WAN and LAN Throughput specifies one of these, depending on that direction you select:
• Bi-Directional—Traffic flowing in both directions.
• WAN-to-LAN—Inbound traffic flowing from the WAN to the LAN.
• LAN-to-WAN—Outbound traffic flowing from the LAN to the WAN.
The navigator shadows the data reduction series.
The Bandwidth Optimization report answers these questions:
• How much data reduction has occurred?
• How much data was removed from the WAN link?
• How much data was sent/received through the LAN/WAN ports?

The Riverbed system reports on performance for periods up to one month. However, due to performance and disk space considerations, data representation in reports for periods longer than the last five minutes are interpolated from aggregate data points. The Optimized Throughput report displays these data granularities:
• Last 1 hour's worth of data is available at 10-second granularity.
• Last 1 day's worth of data is available at five-minute granularity.
• Last 1 week's worth of data is available at one-hour granularity.
• Last 1 month's worth of data is available at two-hour granularity.
