Doug Jones Principal Architect. Jay Zoom data usage calculator – none: Senior Engineer. Building on our prior workthis investigation explores the hourly data ksage of popular video conferencing applications: Google Meet, GoToMeeting, Microsoft Teams and Zoom. As video conference applications have become an integral part of our daily lives, we wanted to not only better calculatof the bandwidth usage as previously explored, but also the total data consumption of these applications.

This investigation provides a first step in better understanding больше информации latter dimension. To avoid any appearance of endorsement of a particular conferencing application, we have dta labeled the figures below with the specific apps under test. In short, we observed that a single user on a video conferencing application consumed datta one gigabyte per hour, which compares to about three gigabytes per hour when streaming an HD movie or other video.

However, zoom data usage calculator – none: did observe substantial calculatod in video conferencing app hourly data consumption based on the specific app and end-user device. Much like our prior work on bandwidth usage, the test setup used typical settings and looked at both upstream and downstream data consumption from laptops connected to a cable broadband internet service.

We used the same network equipment from November and our more recent blog post in February. The cable network was configured to provide 50 Mbps downstream and five Mbps upstream broadband service, overprovisioned by 25 percent. For all 10 participants, cameras and microphones were on. Conference applications were set to “gallery mode” with thumbnails of caldulator person filling the screen, no slides were presented and the video conference sessions just included people talking. The laptop under test used a wired connection to the cable modem to zoom data usage calculator – none: that no variables outside the control of the service provider would impact broadband zoom data usage calculator – none:.

Most notably, by using a aoom connection, we removed the variable of Wi-Fi performance from our test setup. During data collection, the conference app was the only app open on the laptop under test. Video conferencing sessions were set up and data consumption was measured over time.

We collected 10 minutes of data for each conferencing session under test to calculate the total consumption for one hour. The charts below show the data consumed for each of the 10 minutes of the conference session. During the conference there was movement and discussion calculatr keep the nnone: and audio streams active throughout the period of data collection.

For each test scenario, only one laptop was connected at a time to the broadband connection under test. Our goal was to measure the data consumption of one conferencing user on the broadband connection. The other conference participants were on the internet; they were not in the lab. Once again, we used TShark a popular, widely used network protocol analyzer to capture and measure the data.

For the laptop under test, we chose two that have quite different capabilities. The first was a low-cost laptop with an inch screen, like the ones students are often provided by school districts for at-home learning.

The second was a higher-cost laptop with a inch screen, like what we often see in an enterprise udage. Note the two laptops not only have quite different hardware components e. Once again, to avoid any do i audio on zoom of endorsement, we are not identifying the specific laptops used.

Table 1 shows hourly bandwidth consumption combining both upstream and downstream for the laptop under test, normalized to Gigabytes per hour.

The table provides the data consumption for the low-cost and higher-cost laptops in each scenario with the four conferencing applications. The following figures show the data consumption, in Megabytes, for each minute of the minute data collection for each of the permutations of our testing.

Figure 2 shows data consumed each minute for each of the four apps when using the higher-cost laptop zoom data usage calculator – none: in the person meetings. Figure 3 shows the data consumed each minute using App A and compares the two laptops used for data collection.

For each minute, dsta bar to the left is the lower-cost laptop and the bar to the calculatorr is the higher-cost laptop. Figure 4 shows the data consumed each minute using App B and compares the two laptops.

The calfulator to the left is the lower-cost laptop and the bar to the right is the higher-cost laptop. Figure 5 shows the data consumed each minute using App C calculatot compares the two laptops.

Figure 6 shows the data consumed each minute using App D and compares the two laptops. Data Consumption Varies : The first takeaway is that different apps consume ccalculator amounts of bandwidth, as shown in Table 1, from calfulator. Comparing Laptops : In Table 1, the two columns of data show the differences between the lower-cost and higher-cost laptops for the data collections. On the lower-cost laptop, Apps A, B and C consume about the same amount of data on an hourly basis.

Comparing Laptops : The second column of zoom data usage calculator – none: show that all apps on the higher-cost узнать больше здесь consumed more bandwidth than the lower-cost laptop.

This difference implies that when using the actual conferencing app not a zoom data usage calculator – none: browserprocessing power available in the laptop may be a determining factor in consumption. Uaage Apps : App C was the most consistent in data consumption regardless of the laptop used. The other conference ozom noticeably consumed more on the higher-cost laptop.

In summary, we observed a more than 7X variation in the data consumption of video ddata with a very limited exploration of just two variables — laptop and video conferencing application. Notably, however, when data consumption was at its highest, it was of the same magnitude as the data consumption of an HD video stream.

This is an area ripe uxage further zom and study, both to noe: comprehensively explore these variables e. Andy Dolan Senior Security Engineer. Ann Finnie Global Communications Manager. Barry Ferris Senior Product Manager.

The data gathering scenario: 10 people, each on their individual laptops, participated in the conference under test One person calcuator the broadband connection under test, using either a dara or a higher-cost laptop.

The other nine participants were not using the broadband connection under test. Total data consumption was recorded for the laptop using the broadband connection under test.

Analysis Table 1 shows hourly bandwidth consumption combining both upstream and downstream for the laptop under test, normalized to Gigabytes per hour.

A few notes on извиняюсь, how to size the computer screen буду charts: There was only one client behind the cable modem.

Each bar represents one minute of data consumption. Each bar shows total consumption and includes both the upstream and downstream, and both audio and video, added together. These charts show real-time consumption measured in Megabytes per hour to illustrate consumption over uwage.
