NETWORK PERFORMANCE: LINKS BETWEEN LATENCY, THROUGHPUT AND PACKET LOSS

3 major network performance indicators / Base for network troubleshooting:
– Latency is the time required to vehiculate a packet across a network.
Latency may be measured in many different ways: round trip, one way, etc…
Latency may be impacted by any element in the chain which is used to vehiculate data: workstation, WAN links, routers, local area network, server… and ultimately it may be limited, for large networks, by the speed of light.

– Throughput is defined as the quantity of data being sent/received by unit of time.

– Packet loss reflects the number of packets lost per 100 of packets sent by a host.
