Figure 9-6 Connection Traffic Dropped Window
The statistic types used to plot this report are based on the end-point type of the connection. Table 9-4
describes the statistics types needed. The Report Application retrieves all instances (within the plot
period) of the statistics types from the database and calculates the following:
• Percentage of received bytes dropped = (number of bps of received bytes dropped / CIR) * 100
• Percentage of transmitted bytes dropped = (number of bps of transmitted bytes dropped / CIR) * 100
When the Include Peak Data button is enabled, the percent peak values of the dropped traffic for a
selected PVC are displayed. Data for both ends of the connection are plotted side by side. The statistic
types used to plot this report are based on the end-point type of the connection. The Report Application
retrieves statistics from the database and calculates the following:
• Peak number of bytes received bytes dropped (in percentage of CIR) = (peak number of bits received
per second) / CIR) * 100
• Peak number of bytes transmitted dropped (in percentage of CIR) = (peak number of bits transmitted
per second) / CIR) * 100
The following conversions are used to convert to bits per second:
• For FR endpoints, convert bytes received to bits per second (peak number of bytes received * 8) /
(peak interval * 60)
• For ATM/CE endpoints, convert cells received to bits per second, using cmgrd’s conversion formula
(each cell has a 48 byte payload)
peak bps = (peak number cells received * 48 * 8) / (peak interval * 60)
