  • 192.168.90.254 sends 210 bytes every 15 ms
  • Obtain a trace
    • 1: packets sent by 254
    • 2:packets received by 11
    • 3:packets sent by 11
    • 4:packets received by 254
  • Obtain the PDF of interpacket departure and arrival times
  • Provides a visualization of the dynamics of WiMAX
