Here is the definition of QoS according to techopedia.com:
Quality of service (QoS) refers to a network’s ability to achieve maximum bandwidth and deal with other network performance elements like latency, error rate and uptime. Quality of service also involves controlling and managing network resources by setting priorities for specific types of data (video, audio, files) on the network. QoS is exclusively applied to network traffic generated for video on demand, IPTV, VoIP, streaming media, videoconferencing and online gaming.
Now lets break it down into more simple terms...
Typically, you have a lot of different devices on your network. If you work at an office you could have 20 computers, 24 VoIP phones, and a few other various devices.
If you work from home you could have your laptop, desktop, VoIP phone, and be streaming your favorite binge worthy series on Netflix (don't worry we won't tell your boss about that).
If you are like the average employee you have 10 different tabs open and those may include listening to your favorite music app, watching a YouTube video, and you might be on a conference call with your other office across the country.
While all these activities are going on in your network it could slow the speed down. Which is why it is important to have a Quality of Service device to direct the network to where you want it to work first.
A QoS device can make sure that the device you prioritize gets the bandwidth first so it runs smoothly. A delay in service while working on your computer is rarely noticeable, however a delay on you VoIP service can cause mission critical error and make it sound like you are going in and out of service on your cell phone.
There are a lot of QoS devices on the market. Here are 3 top questions to ask to make sure that you choose the right one to make sure your calls are crystal clear at all times:
1. What is your QoS service and warranty plan?
2 Are you able to pull reports from your Qos?
3. What capabilities and features does your Qos offer?
When picking a QoS remember to do your research and ask your trusted IT partner for recommendations!
