Network latency testing tools help determine whether your network infrastructure is sufficiently capable of supporting your business goals by identifying any performance bottlenecks.

These network latency testing tools evaluate quality of service (QoS), which is an important and performance-limiting factor for network communications. Challenges to QoS and network latency drive the need to test network performance thoroughly across different locations, devices, and applications – so these testing tools play a key role. 

What is Network Latency?

Latency is the time it takes for data to travel between two points on a network. It includes both delay (the time between the sender sending out a packet and the receiver receiving it) and jitter (the variation in the time taken by successive packets) as well as other factors like queuing delays, transmission errors and bottlenecks in network components such as switches, routers, modems and servers.

It’s measured in milliseconds (ms) for the “round-trip time” (RTT), or the time it takes for a message to be sent, travel through a network, and then return to the computer that sent it, of a network transaction. Because of the physical limitations of the transmission process, some latency is unavoidable.

While latency is inherent in all networks, it should be kept to a minimum to ensure optimal performance. For example, the time it takes for data to travel from one computer to another over a wired network is usually much less than the time it takes to travel over a wireless network. The main reason is that wired networks generally have much lower latency than wireless networks.

What are Network Latency Testing Tools?

Network latency impacts user experience, application performance, and statistical network analysis. Therefore, enterprises need to monitor network latency and test it frequently to identify fluctuations and sources of high-latency locations in their networks.

Network latency testing tools identify and track the time it takes for packets of data to travel between two locations on the internet or from one network device to another. This data gives network engineers valuable insights into the speed of their networks and helps them diagnose network issues related to speed and delays in data communication.

Ping (Packet Internet or Inter-Network Groper) is a network latency testing tool available on all operating systems. It uses the Internet Control Message Protocol (ICMP) to measure how long it takes for a message to be delivered from one computer to another.

The lower the latency, the better. Network administrators use ping tools and quality assurance tools to diagnose and troubleshoot network problems. Ping tools will help you identify where your infrastructure is causing problems on your network and help you get them fixed quickly. It’s a simple way to check if connectivity issues exist between two devices or on any segment of your network.

To use ping, open a console or terminal window and type “ping” and a domain like or an IP address. You should see some statistics, including TTL (time to live), which measures how many hops away the destination is, and round-trip time which gives an idea about how much lag is happening.


  • It is the fastest way to monitor network latency.
  • Works on all operating systems with console or command line capability.


It’s free to use.


Traceroute, or tracert, is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an IP network. Van Jacobson originally developed it in 1987.

It uses ICMP echo request messages to determine latency, packet loss, round-trip times, and other connection parameters from one host to another over an IP network. This method of testing latency is also available on all OS systems. For example, use the tracert command on Windows machines and the traceroute command on Linux and Mac machines.


  • Traceroute utilizes IP packets’ TTL fields to find intermediary routers.
  • Traceroute implementations use ICMP echo reply messages.


This tool is free to use.

Key Features of Network Latency Tools

The best tools provide users with real-time visualization, alarm notification, and graphical reports. Practitioners can also integrate these tools into network management software, such as network monitoring, IT management, and network security.

Network latency tools typically have a wide range of features, including:

  • Automatic Discovery of Devices in a Network: You don’t have to configure the tool to collect data manually. It can discover devices on the network, collect data, and store it in a central database.
  • Continuous Monitoring: The tool can constantly monitor network traffic and identify trends in network latency, bandwidth utilization, and device health.
  • Customizable Alerts: You can customize alerts to let you know when network latency is rising or if a network connection has failed.
  • Graphical Visualization: Network latency tools provide real-time graphical visualization of data collected from different devices in your network.

Why are Network Latency Tools Important?

With the recent growth of cloud storage, high-bandwidth video streaming, and cloud computing, there has been increased attention on the ability of networks to provide consistent performance. Network latency is an important factor in measuring the performance of any network, as minimum acceptable performance thresholds will depend on the applications you’re running over your network.

Latency is also important in measuring a network’s service quality or how well it performs. You’re primarily concerned with the latency of your network when you need real-time communication between applications or when you are transmitting data with strict performance requirements.

For example, with the rise of virtual and augmented reality applications, wireless network latency has become a big issue for businesses. In addition, enterprises rely heavily on instant messaging, video conferencing and other multimedia communications, which can slow down latency issues.

Network latency tools provide insight into many key performance indicators for your network, including network paths, network health, transmission errors, and network utilization. These tools help monitor the time data packets reach their destination. It measures the round trip time of messages transmitted from one node, such as one computer, on a network to another and back again. When used properly, this tool can help identify sources of lag within your network as well as help solve them.
