For a given time frame, NetScaler MAS provides a graph that shows the ratio of optimized to unoptimized video sessions in the time frame. It also displays the percentage of bandwidth saved by optimization. The percentage of bandwidth saved is calculated with the following formula:
Percentage of bandwidth saved = Average optimized ABR video Data Volume / Average of unoptimized ABR Video Data Volume.
To see the percentage of bandwidth saved by optimization, log on to NetScaler MAS, navigate to Analytics > Video Insight, and click ABR Video. Then, in the right pane, select a time frame from the drop-down list. You can further customize the time frame by using the time-frame slider. Click Go and select the Network Efficiency tab.
