About this interactive

How the demo turns readings into statistics: - **Loss:** the requests that got no reply, as a share of those sent. 182 sent and 182 received is 0% loss. - **Uptime:** the time the link was up, as a share of the time measured. Down 1 minute out of 10 is 90% uptime. - **Latency:** the average of the reply times. - **Jitter:** the demo's simple method takes how far each reply is from the average, then averages those gaps. Other tools measure jitter from one reply to the next, so their figure can differ. - **Bits and bytes:** a byte is 8 bits. A 200 Mbps speed test moves at most 25 megabytes each second. Network speeds use decimal prefixes: 1 Mbps is 1,000,000 bits per second.

Key terms

Packet Loss
The failure of one or more transmitted packets to arrive at their destination, typically expressed as a percentage of total packets sent.
Uptime
The amount of continuous time a network device or service has been running without interruption, often expressed as a percentage of total time available. High uptime percentages (such as 99.9%) indicate a reliable network, while planned and unplanned downtime reduces this figure.
Latency
The time delay between sending a request and receiving a response over a network.
Jitter
The inconsistency or variability in the timing of data delivery across a network, which can disrupt real-time applications like video conferencing and gaming.
Bandwidth
The maximum rate of data transfer across a network path, typically measured in bits per second.
Megabit per second
Mbps
A data transfer rate equal to one million bits per second, the standard unit for rating broadband internet connections and network interface speeds.
