What is the difference between bandwidth delay and latency?

Bandwidth is a measure of how much data can move (measured in X bits per second) and latency is a measure of the delay in moving that data (measured in milliseconds), between two nodes. In other words, bandwidth measures size and latency measures speed. Bandwidth is crucial when you need to move large files.

What is the difference between throughput and bandwidth?

Throughput and bandwidth are two different but closely related concepts. To summarize, throughput is an actual measure of how much data is successfully transferred from source to destination, and bandwidth is a theoretical measure of how much data could be transferred from source to destination.

How does latency affect throughput?

The delay before acknowledgment packets are received (= latency) will have an impact on how fast the TCP congestion window increases (hence the throughput). When latency is high, it means that the sender spends more time idle (not sending any new packets), which reduces how fast throughput grows.

What is the difference between throughput and Goodput?

The average throughput tells a user how much data is being transferred from the desired source. Similar to throughput, goodput is the rate at which useful data arrives at a destination. While throughput is the measurement of all data transferring (whether that be useful or not), goodput measures useful data only.

Is Ping the same as latency?

While the ping is the signal that’s sent from one computer to another on the same network, latency is the time (in milliseconds) that it takes for the ping to return to the computer. So latency is a measurement of the entire round trip of that signal while ping is just one way.

Is RTT the same as latency?

Network latency is closely related, but different than RTT. Latency is the time it takes for a packet to go from the sending endpoint to the receiving endpoint. RTT includes processing delay at the echoing endpoint.
