Report Computations

The following describes the computed connection speed:

ConnectionSpeed = avg ResponseSize / avg ResponseTime 

where:

ResponseSize = ResponseHeaderSize + ResponseBodySize
ResponseTime = TimeLastResponsePacketAcknowledged - TimeOfFirstResponsePacket

Connection Speed is calculated as the average values of all hits in the session. Any detected client user interface events are ignored. Based on the computed Connection Speed, the Connection Types are derived by using the following thresholds:

• If speed < 57,344 bytes/sec (56 KB/sec), then Connection Speed = Dial Up.
• If speed < 131,072 bytes/sec (128 KB/sec), then Connection Speed = ISDN.
• If speed < 716,800 bytes/sec (700 KB/sec), then Connection Speed = DSL.
• Else Connection Speed = T1 (>=1544 KB/sec).

If the data is not available to compute Connection Speed, the Connection Type is designated as Unknown.
