network performance to determine how well the network would perform for a
Microsoft Teams or Skype for Business Online call. The tool tests the
connection to Microsoft Network Edge by streaming a set of packets to the
nearest edge site and back for approximately 17 seconds for a configured number
of iterations. The tool reports:
àPacket loss
àJitter
àRound-trip latency
àReorder packet percentage
