Making Zoom go Zooooom!

Because of COVID-19, Zoom has experienced phenomenal usage growth. For many people, this is their first experience with video chat.

All video chat requires adequate bandwidth as a start. However, in order to experience the best possible video calls - both audio and video - there is another necessary ingredient: Quality of Service (QoS). QoS, when used, prioritizes network traffic, thereby giving video chat such as Zoom higher priority over other network traffic such as web browsing.

Zoom has published technical articles on implementing QoS at both the router level, and at the PC level for Windows.

QoS is available in routers, but most users, especially home users, are not acquainted with using it.

The following is a link to a Zoom article on implementing DSCP (Differentiated Services Code Point) Marking in a router for QoS, and for implementing it on Windows PCs.

This is especially useful if you are low on bandwidth, or have a lot of users at home, all consuming bandwidth. Implementing either or both will improve your Zoom calls.

If you are using Windows 10 Home or Home Premium, you will not be able to implement this on your PC, as it lacks the Group Policy Editor. 

We will be publishing a separate article next week on how to add the Group Policy Editor to PCs running these versions of Windows so you can then implement QoS for Zoom. Group Policy Editor is part of Windows 10 professional by default.
