What Is Network Traffic?

For many IT professionals, the flow of data has become as essential as the air we breathe. This constant movement of information, akin to cars zooming down a busy freeway, is what we refer to as network traffic.

What is a network?

A network is composed of interconnected endpoints and network nodes, such as computers, servers, and routers, that communicate with each other to share resources and information. These networks can be small, like a home setup, or expansive, like the internet itself, which is a global network of networks.

What is network traffic?

Just as vehicles travel on roads, data packets move across networks. This movement of data packets from one device to another over a network is known as network traffic. It can include everything from emails sent, websites visited, files downloaded, and more.

Types of network traffic

Real-time traffic

Real-time traffic refers to the type of network traffic where data packets must be delivered within a specific time frame to retain their value. This is commonly seen in applications such as video streaming, online gaming, and VoIP calls. The delivery of these data packets is time-sensitive because delays can lead to buffering, lagging, or poor quality of service.

Non-real-time traffic

On the other hand, non-real-time traffic involves data that does not require immediate delivery. Emails, file downloads, and software updates are examples of this type of traffic. Even if there are slight delays in the transmission of these data packets, the overall user experience is not significantly affected.

Understanding these two types of network traffic helps in efficient network management. Prioritizing real-time traffic over non-real-time traffic can ensure smooth operation of time-sensitive applications, thereby enhancing user experience.

Common network traffic problems

Network traffic, while vital, can present certain challenges. Here are some common problems:

  • Congestion

Much like a traffic jam on a road, network congestion occurs when too much data tries to pass through at once, slowing down the entire network.

  • Bandwidth hogs

Certain applications or users may consume an excessive amount of bandwidth, leaving less for others and affecting overall network performance.

  • Security threats

Cybersecurity threats are on the rise, and threats like malware can infiltrate networks and create malicious traffic, leading to potential data breaches.

3 reasons to monitor network traffic

Monitoring network traffic is crucial for several reasons:

  • Performance optimization

By understanding what’s happening on your network, you can identify bottlenecks and optimize for better performance.

  • Security

Regular monitoring can help detect unusual patterns or suspicious activities, enabling swift response to potential threats.

  • Planning and forecasting

With insight into network usage trends, you can plan for future upgrades or expansions effectively.

Network traffic is essential in this digital world

Network traffic is the lifeblood of our interconnected world. Understanding its nature, addressing its challenges, and monitoring its flow are critical steps in maintaining a healthy and secure digital environment. Whether you’re a small business owner or an IT professional in a large corporation, monitoring and managing your network traffic with a network management tool like NinjaOne can lead to improved performance, enhanced security, and informed decision-making.
