[TCP/IP] Computer network performance indicators

Network performance indicators are indicators for measuring network performance, mainly including rate, bandwidth, throughput, delay, and bandwidth-delay product.

Rate: The rate at which a host connected to a computer network transmits data bits on a digital channel. The unit is b/s kb/s mb/s gb/s

Bandwidth: The digital channel The highest data rate that can be transmitted. Check that my network card is 144Mbps
Throughput: the amount of data passing through a certain network per unit time
Latency: send delay, transmission delay, processing delay, queuing delay
Send Delay = data block length (bits)/bandwidth (bits/second)
The delay bandwidth product represents how much data is on the way

RTT round trip time
Use ping test, ping the gateway first, Then ping Baidu and Google dns

# Utilization rate: Channel utilization rate (with data passing through time/total time) and network utilization (weighted average of channel utilization)
