Throughput is the number of packets a network can send through itself at any one time
Measured in bits over time (kbps, mbps)
Example: The number of cars that can fit on a road over a given time
Frame Loss is the number of packets that get lost over a given cable in a network.
Can be affected by internal factor such as network performance, and overall load, or external factors like interference or noise on the lines.
Often measured by percentage of frames lost
Example: The number (or percentage) of cars that don’t make it to their destination
Latency is the time it a takes a packet to get through a network Measured in time (often milliseconds)
Example: The speed a car can travel on a road at a given time
Jitter is the changes in packet speed over time, causing data bunching. Large amounts of jitter often cause frame loss.
Example: The difference between driving at a consistent speed on the freeway versus driving in stop-and-go traffic

LATENCY TEST
Latency Results Summary
To ensure the highest quality of service, latency on both switches is minimal at maximum distance. The accepted industry standard for VoIP is 150 milliseconds. Both switches perform at 0.005-0.018milliseconds
(5-18 microseconds) of latency at the maximum frame size tested. This is more crucial for real time applications like voice calls or video conferencing.
JITTER TEST
