Ps_OWD analysis

[yuanlii]

Analytics Plan: (Oct.11)

1. for the entire network, get the average delay_mean, delay_median, delay_sd values (根据距离不同, delay_mean和delay_median 可能在pair之间不具可比性，但delay_sd可以在不同pair 之间比较

2. for each src - dest pair, get the average delay_mean, delay_median, delay_sd values

   • can compute multiple (e.g., 10 days), then averaged those 10 days results (注意：同比, week over week, year over year, etc.)

3. for each src - dest pair, 可以比较从timestamp t1 --> t2这期间，delay_median, delay_mean, 'delay_sd`的变化trend (注意：时间区间的选择同样注意·同比· | 时间间隔长度needs more thoughts)

4. cross-correlate owd data among multiple src-dest pairs => needs more thoughts

5. cross-correlate owd metric with other network metrics, e.g., throughput, packet_loss, etc. => for anomaly detection
