What is Network Latency? Causes, Impact & How to Reduce It

A user thinks that clicking a hyperlink on the website or typing messages requires immediate responses. Still, there is always a distance that needs to be traveled by information before it reaches the server. When such a process takes more time than planned, users have to wait. It is essential because it impacts the overall speed of communication.

Basics of Network Latency

Network latency is the term for any delays or lag time associated with information transfer. Usually, it is measured in milliseconds.

To give you an example, think of the postal service. The time spent by your letter on traveling to the recipient and getting the answer back will represent RTT in case of latency. The less time spent in this process, the better.

Common Reasons behind Network Latency

Once the reasons behind latency become apparent, addressing the problem becomes simpler. Here are some possible reasons why it happens that data can be delayed during transfer:

• Distance Traveled

  While data moves incredibly fast, this does not mean that it breaks the natural laws. Therefore, the longer distance between the user and the host machine translates to extra time required for data transmission.

• Media Used

  The speed of information transmission depends greatly on whether it goes through fiber optic cables, older copper wiring, or slower satellite technologies.

• Network Traffic

   Similar to a regular highway where too many cars slow things down, the transmission slows down when many devices are connected to a network.

• Outdated Hardware

  Routers, switches, and other hardware that are too old to handle the incoming stream of data create a bottleneck, delaying packets in the process.

Effective Methods for Addressing Delays

Though there is no way to overcome all delays due to geographic location, a company can still implement several strategies:

• Leverage CDNs: CDNs will store the content of a website on servers around the world so that each individual accessing the site gets it from the closest possible server making them essential for improving speed and reliability in global e-commerce environments.
• Compress Data: Images and code that are very large can be optimized for efficiency.
• Upgrade Equipment: Old routers should be upgraded, and slower internet access lines should be replaced with fiber-optic connections.

Conclusion

There can be no doubt that speed and stability of the network have ceased to be a matter of luxury, but have become the basic condition of our daily work with computers. After all, the only way to ensure the efficient functioning of business processes and to retain user loyalty is to maintain low network latency.
