| Index | Index number of a measurement record. Each measurement record is corresponding to a continuous measurement period. Clicking on the index number will lead you to the raw data files of each record. |
| Path | This is the identifier of the measured path. It is in the format of <source host_id>-<destination_host_id>. Clicking on it will lead you to graphs of spatial congestion distribution across links of a path over different time-scales. |
| Duration | Duration of the measurement. |
| Samples | Total number of probe samples collected during the measurement. Each probe sample consists of a set of probes. For example, if 4-packet probing is in use, the set of probe includes an f probe, a b probe, an s probe, and a d probe. |
| WCC | This is the summarized weighted congestion count (WCC) of a path. Clicking on it will lead you to the graphs of per-link WCC trace. |
| WCF | This is the summarized weighted congestion frequency (WCF) of a path. Clicking on it will lead you to the graphs of per-link WCF trace. WCF is also called congestion intensity. |
| Sender | The sender host. Clicking on it will lead you to a directory that holds all raw measurement records of this sender. |
| Receiver | The receiver host. Clicking on it will lead you to a directory that holds all raw measurement records of this receiver. |
| Start_time | The time when a measurement starts. |
| E.R. |
End reason — a code representing the reason that measurment ends. The following are meanings of codes: 0 - Unknown reason 1 - Route alteration or route change 2 - Normal quitting due to undesirable conditions 3 - No heartbeat detected for a certain period of time 4 - Ended by SIGTERM signal 5 - No heartbeat detected during router alteration tracing 6 - "pong_daemon" quits 7 - Measurement finished |
