High jitter, or high variation in delivery time, results in choppy voice calls or glitchy-sounding looking video quality for businesses using cloud-based phone systems. Jitter can affect applications that rely on very accurate timing, such as those in manufacturing or other automation-based industries. If your business relies on video streaming, VoIP, or other applications where real-time data is important, you should test your internet quality regularly.
Low quality can result in frustrated employees, lower productivity, and lost opportunities. If you are Fusion Connect customer, contact our customer service team for any questions you have about your connection quality. Return to Your Previous Service Results. Internet Quality Test Upload and Download speeds are one thing, but connection metrics like jitter, packet loss, and latency affect the reliability and clarity of applications like VoIP and video streaming.
Test Your Internet Quality You will be redirected to our internet quality test tool. Packet Loss, Latency, and Jitter Explained Packet Loss Packet loss occurs when packets of data do not reach their intended destination - usually because of network congestion.
Test Internet Quality Regularly If your business relies on video streaming, VoIP, or other applications where real-time data is important, you should test your internet quality regularly. Check for Available Speeds See services and special offers for your business. The time it takes the data package to complete the roundtrip is called latency, also known as ping.
To achieve an accurate reading, multiple ping tests are conducted consecutively, with the final result being the average of all these tests.
All these are automatically handled for you when using Speedcheck. But you should take one crucial aspect into account to test speed accurately. Choose the right tool. This depends on the device you want to use, being a phone or tablet, or a computer. To check internet speed on a computer, use your browser and the app on this website.
To achieve accurate results on mobile devices, you should download our iOS or Android app, respectively. This is especially important when running a WiFi speed test. Because browsers on mobile devices have poor performance, we suggest using a mobile app written in native code to ensure the most accurate speed test results. The speed at which your device can receive data from the internet. It's calculated by dividing the total throughput of data in a given time frame by its duration.
Therefore its unit is denoted by units of data over time. As opposed to download speed, upload speed characterizes the amount of data your device can send to the internet. It's calculated the same way and is therefore denoted in the same units. The ping or latency describes the delay of a signal due to the time it takes that signal to travel to its destination. In this context, it represents the time it takes a data package to complete its roundtrip over the network and the acknowledgment from the server that it was received.
As a value of time, it is denoted as such, most often in Milliseconds ms. This sharing is disabled by default and must be enabled by your administrator. The results are shown in the Summary and Details tabs. The summary tab shows a map of the detected network perimeter and a comparison of the network assessment to other Microsoft customers nearby. It also allows for sharing of the test report. Here's what the summary results view looks like:. Here's an example of the details tab output.
On the details tab we show a green circle check mark if the result was compared favorably. We show a red triangle exclamation point if the result exceeded a threshold indicating a network insight. The following sections describe each of the details tab results rows and explain the thresholds used for network insights. The user location is detected from the users web browser. It can also be typed in at the user's choice.
It is used to identify network distances to specific parts of the enterprise network perimeter. Only the city from this location detection and the distance to other network points are saved in the report.
We identify the network egress IP address on the server side. Location databases are used to look up the approximate location for the network egress. If the location looked up from the network egress IP address is not accurate, this would lead to a false result. To validate if this error is occurring for a specific IP address, you can use publicly accessible network IP address location web sites to compare against your actual location.
We determine the distance from that location to the office location. This is shown as a network insight if the distance is greater than miles kilometers since that is likely to increase the TCP latency by more than 25 ms and may affect user experience. The map shows the network egress location in relation to the user office location indicating the network backhaul inside of the enterprise WAN. Implement local and direct network egress from user office locations to the Internet for optimal Microsoft network connectivity.
Improvements to local and direct egress are the best way to address this network insight. We identify whether proxy server s are configured on the local machine to pass Microsoft network traffic in the Optimize category. We identify the distance from the user office location to the proxy servers. The distance is tested first by ICMP ping. We show a network insight if the proxy server is further than miles kilometers away from the user office location.
This test detects if you're using a VPN to connect to Microsoft A split out workload avoids the VPN entirely. A tunneled workload is sent over the VPN. A selective tunneled workload has some routes sent over the VPN and some split out. A passing result will show if all workloads are split out or selective tunneled.
Network latency between the user office location and the Exchange Online service is compared to other Microsoft customers in the same metro area. This means their users will have better performance in the Microsoft user interface. This network insight is generated on the basis that all users in a city have access to the same telecommunications infrastructure and the same proximity to Internet circuits and Microsoft's network.
This shows the DNS server configured on the client machine that ran the tests. The distance from the user office location to the DNS Recursive Resolver server location is then calculated. This is shown as a network insight if the distance is greater than miles kilometers.
The location looked up from the network egress IP Address may not be accurate and this would lead to a false result from this test. To validate if this error is occurring for a specific IP Address you can use publicly accessible network IP Address location web sites. This network insight will specifically impact the selection of the Exchange Online service front door. To address this insight local and direct network egress should be a pre-requisite and then DNS Recursive Resolver should be located close to that network egress.
The in-use Exchange service front door is identified in the same way that Outlook does this and we measure the network TCP latency from the user location to it. The TCP latency is shown and the in-use Exchange service front door is compared to the list of best service front doors for the current location. This is shown as a network insight if one of the best Exchange service front door s is not in use.
Not using one of the best Exchange service front door s could be caused by network backhaul before the corporate network egress in which case we recommend local and direct network egress. It could also be caused by use of a remote DNS recursive resolver server in which case we recommend aligning the DNS recursive resolver server with the network egress.
We calculate a potential improvement in TCP latency ms to the Exchange service front door. This is done by looking at the tested user office location network latency and subtracting the network latency from the current location to the closets Exchange service front door.
