How Can QoS Improve Your Company's Internet Reliability?
What Does Quality of Service Do? Imagine your bandwidth capability as a highway, and each internet activity as a vehicle on that highway. Some vehicles will be like a tiny smart car (sending a Slack message), while others will be a large semi-truck (streaming an HD video call). If you don’t have any controls as to which vehicles can use which lanes, the highway can easily come to a standstill for everyone when there is too much traffic. But imagine you added a special “high priority” lane to the highway and only allowed the most important vehicles to use it. Then, no matter how much traffic there was on the highway, the most important traffic could still go at top speed and be unaffected. That’s what QoS does for bandwidth. It’s a mechanism to tell your router which devices or applications should get the highest priority (i.e. be allowed to travel in the fast lane) and which should be limited so they don’t interfere with the connection of other apps. With QoS, you can:
Designate several different bandwidth priorities (e.g. highest, high, standard, low)
Designate bandwidth allocation by app or by device
Limit the amount of bandwidth a certain device or app can use
Keep traffic running more smoothly, reducing network slowdowns
