Definition

In depth

Ping — or more precisely round-trip time (RTT) — is the single most important latency metric for online gaming. It measures how long the network takes to acknowledge one small packet, expressed in milliseconds.

Ping is a physical constraint first and a routing problem second. The speed of light through fibre puts a hard floor on how low your ping can go for a given distance; no product can beat that floor. What can be improved is the extra time added by suboptimal routing, congestion or wireless overhead.
