Control and Test Sessions:

  • Control Session: Establishes the parameters for the test session, such as the IP addresses, ports, packet sizes, and the duration of the test.
  • Test Session: Where the actual performance measurements occur, involving the exchange of test packets between the two endpoints.
Key Metrics
  • Latency: The time taken for a packet to travel from the sender to the receiver and back.
  • Jitter: The variation in latency over a series of packets.
  • Packet Loss: The number of packets sent that are not received by the destination.
