What is Network Latency?

You may be wondering what network latency is? The answer to that question is very varied and depends on many factors. Latency ranges are not the same for every network and depends on the application. VoIP needs lower latency, while video requires higher latency. Network administrators must consider these factors and allocate bandwidth accordingly. A latency that exceeds this range will not be effective and will make it difficult for your business to operate.

Latency is the time it takes for a request to travel across a network. This measurement is commonly referred to as round trip time, as it indicates how long a packet takes to travel from its origin to its destination. Ideally, network latency should be as low as possible. The best way to reduce latency is to make your network faster and more reliable. There are two ways to calculate network latency. You can calculate round trip time by dividing the request’s total time by the number of packets.

Latency affects the speed of page load times. While massive images and bad code may slow a website’s loading time, network latency affects the speed of the page. While data is stored on physical hard drives, the path to reach them is affected by network connectivity. As data travels across the internet, it passes through multiple Internet Exchange Points (IXPs). The routers break down the packets and process them. All of this additional activity increases the overall RTT.
