What Is the Difference Between the Packet Loss Rate Displayed During the Ping Test and That Displayed on a Hard Terminal? How Does the System Detect the Packet Loss Rate of a Hard Terminal?

  • In the ping test, the Internet Control Message Protocol (ICMP) is used to ping a server address at the network link layer. A pingable server address indicates that the network layer is normal. Video meeting packets are transmitted using IP+UDP. The transport layer is normal and the ports are reachable only when the UDP connection is normal.
  • The system calculates the expected number of received packets based on the maximum and minimum packet sequence numbers within 6s. It also records the actually received packets. Then the system uses the following formula to calculate the packet loss rate: (Expected number of received packets – Actual number of received packets)/Expected number of received packets.
