Changing your telephone adaptor or other VoIP-specific software can help. Even your headset can cause latency. Signal conversion — If your system is converting your signal to or from analog and digital, this could cause latency.
The slowing of your network can be extremely problematic in the business world, where time is such a precious commodity. As your network grows bigger, having additional connections means more points where delays and issues can happen. Problems can increase again as more and more organizations connect to cloud servers, use more applications and expand to accommodate remote workers extra branch offices. Everyone has experienced latency in various aspects of daily business, and it can severely threaten deadlines, expected outcomes and eventually ROI.
This is where comprehensive network monitoring and troubleshooting comes into its own. Network monitoring and troubleshooting can quickly and accurately diagnose and identify the root causes of latency and put solutions in place to reduce and improve the problem.
Before you can do anything to improve your network latency, you need to know how to calculate and measure it. If you feel that your network is running slow, you can check your latency manually by using Windows.
Add up all the measurements, and the resulting quantity is the latency between your machine and the website in question. Then, check application performance to determine whether applications are acting unexpectedly and potentially placing pressure on the network. Subnetting is another way to help reduce latency across your network, by grouping together endpoints that communicate most frequently with each other. Additionally, you could use traffic shaping and bandwidth allocation to improve latency for the business-critical parts of your network.
Finally, you can use a load balancer to help offload traffic to parts of the network with the capacity to handle some additional activity. Manually troubleshooting issues across a large network can become complex, which highlights again the importance of network monitoring and troubleshooting tools.
To check if any of the devices on your network are specifically causing issues, you can try disconnecting computers or network devices and restarting all the hardware.
Testing network latency can be done by using ping or traceroute tracert , although, comprehensive network monitoring and performance managers can test and check latency more accurately. Maintaining a reliable network is an important part of a smoothly operating business. Network monitoring and troubleshooting tools are the best way to keep tabs on latency, as well as the other most troubling network problems, packet loss and jitter. You can typically set network standard expectations for latency and create alerts when the network latency reaches a certain threshold above this baseline.
Network monitoring tools can help you set up data comparisons between different metrics. This can help you identify performance issues, such as application performance or errors also affecting network latency. A network mapping tool can also help you pinpoint where within the network latency the performance issues are occurring, which allows you to troubleshoot problems more quickly. By improving your network speed and reducing latency, your business processes will also make leaps and bounds towards efficiency and high performance.
This comprehensive guide has been created to define network latency and to help identify, understand and troubleshoot the most common problems related to latency in computer networks.
The key takeaways are that network latency, jitter, and network packet loss can severely impede clear communication and universally affect your user experience.

How 'literally' can mean "figuratively". Imagine a network path is a long pipe filling a bucket with water. TCP requires that once the bucket is full, the sender has to wait for an acknowledgement to come back along the pipe before any more water can be sent.
In real life, this bucket is usually 64KB in size. It's called the TCP Window. Let's imagine a scenario in which it takes half a second for water to get down the pipe, and another half a second for the acknowledgement to come back In this scenario the TCP protocol would prevent you from sending any more than , bits in any one second period. The most you could possibly get down this pipe is , bit per second bps - otherwise expressed as half a megabit per second.
Notice that barring other issues that may slow things down the only thing driving this is latency. Clearly, if you have latency-sensitive applications then you need to be mindful of the latency of your network. Look out for situations where there might be unexpectedly excessive latency that will impact throughput. For example, international circuits. Another interesting case is with 4G Cellular WAN , where one uses the 4G network to create a reliable, high speed connection to your corporate network, or to the internet.
This involves the use of multiple SIMs that are often bonded together into a single, highly reliable connection. In this case, the latency of the bonded connection tends towards the greatest latency of all the individual connections.
If you consider the difference between 3G and 4G in the list above, you'll see that including 3G connections can have a big impact on the overall latency. Remember, though, that latency is not the only cause of poor application performance. To get to the bottom of such problems, you often need an Application Performance Audit , or perhaps to set up Critical Path Monitoring on your IT estate.
Generally, you'll track latency and other performance-impacting indicators using a Network and Application monitoring toolset. See this post for more on building the best managed network provider monitoring. Have a look at this calculator. RH13 6HS.
