Network delay refers to the round-trip time when a data packet is sent from the user's computer to the website server and then immediately returned from the website server to the user's computer. There is a delay between transmission and final reception of signals, and every network is dominated by this delay.
In many games, the word network delay often appears, some players are high and some players are low. Because of the complexity of the Internet, the dynamic change of network traffic and the dynamic choice of network routing, the network delay is constantly changing. The smaller the network delay and the change of network delay, the better the network quality.
Extended data
Causes of network delay
1. When there are too many routing and forwarding processes in the link between the local computer and the server, the network delay will be obvious.
2.? Insufficient network bandwidth. If the bandwidth is only 10Kbps, but there are many applications that need to transmit 200Kbps data far beyond the bandwidth, a lot of data will be lost, which is manifested as response delay.
3. Insufficient server processing capacity will also cause response delay.
