Chart and Table Descriptions
Note At the device level for WAAS Express devices, only charts for supported accelerators are available. In
all charts, pass-through traffic for WAAS Express devices is considered as zero.
TCP Optimization Charts
The following TCP optimization charts are available:
• Compression Summary, page 1-15
• Compression Summary Over Time, page 1-15
• Effective WAN Capacity, page 1-15
• Throughput Summary, page 1-16
• Traffic Summary, page 1-16
• Traffic Summary Over Time, page 1-16
• Traffic Volume and Reduction, page 1-16
Compression Summary
The Compression Summary chart displays a bar chart of the percentage of traffic reduction (excluding
pass-through traffic) for the top ten applications with the highest percentage of traffic reduction. Two
additional tabs allow you to see the compression of the top ten applications by volume and the bottom
ten applications with the lowest compression.
Formula:
% Reduction Excluding Pass-Through = (Original Excluding Pass-Through – Optimized) / (Original
Excluding Pass-Through)
Compression Summary Over Time
The Compression Summary Over Time chart displays a graph of the percentage of total traffic that was
reduced by using the WAAS optimization techniques. This chart excludes pass-through traffic in the
results. You can customize the chart by choosing specific applications to include; the default is all traffic.
Formula:
% Reduction = (Original Excluding Pass-Through – Optimized) / (Original Excluding Pass-Through)
Effective WAN Capacity
The Effective WAN Capacity chart displays the effective increased bandwidth capacity of the WAN link
as a result of WAAS optimization, as a value between 1X (times) and 100X. You can choose which
applications to include; the default is all traffic.
Formula:
Effective WAN Capacity = 1 / (1-% Reduction Excluding Pass-Through)
% Reduction Excluding Pass-Through = (Original Excluding Pass-Through – Optimized) / (Original
Excluding Pass-Through)
