The relationship between network latency and network speed, network latency and network speed

Network latency is not necessarily inversely or directly proportional to network speed.

The network latency is fast, which means that the reflection time between your host and the server is short, even if you have a speed of 512k, the delay will be very small if you only do ping.

Slow network latency, means that the reflection time between your host and the server is long, you have 100m optical fiber, but your ten machines at the same time ** the bandwidth is full, at this time, no matter what address you ping the external network, there will be a large delay, or packet loss. Except, of course, if the router is set with ICMP precedence**.

So to speak. So if you want to ping normally. It's a good idea to limit the downlink and uplink bandwidth of each computer on the intranet, so that even if one machine fills up its own bandwidth, it won't affect anyone else.

Network latency is the performance of slow network speed or server card.

First of all, for the same access traffic in a certain time in the network segment, the network delay is inversely proportional to the network speed (bandwidth), that is, the larger the bandwidth, the smaller the delay, of course, the bandwidth is only a factor that affects the delay, and there is the problem of the processing speed of the nodes in the network to the packet, when the packet is large, the processing time requires more and the delay increases, and the processing capacity of the server node being accessed in the network also directly affects the speed of your access. It is also important to consider the difference between a LAN and a WAN. It's a bit more complicated in between.

Therefore, the network speed limit cannot theoretically reduce the network latency. In addition, you can trace the route path with traceroute for further analysis.

Theoretically, the higher the bandwidth, the higher the priority in the network topology, and the faster the corresponding response speed, and the higher the bandwidth between the user and the ISP, the more data per second, and the smaller the latency.

However, the latency of Qihuai is determined by many factors, every server (router) on the network is a node, and the response speed of all nodes together is their own network delay.

The other nodes will recalculate the route, but there will be a timeout timer before the route is recalculated, and the route will be recalculated only when the response time of the destination node exceeds the timer. There is also the influence of DNS servers and so on.

Not to be confused. The ISP can only ensure that the user's access network bandwidth and network latency are not problematic, and the service with other nodes cannot be guaranteed.

Network latency (network latency) refers to the time it takes for a packet to travel from a user's computer to a server and then immediately from the server back to the user's computer. In layman's terms, it is the time it takes for data to travel from one side of the computer to another.
