Windows 7: What is QoS Packet Scheduler and how it affects my system?

What is QoS Packet Scheduler and how it affects my system?

Hello,
I'm wondering what is QoS Packet Scheduler's job exactly.
I have recently signed a higher priority to my computer through router. Does it affect anything either being enable or disabled? I hope not, otherwise anyone could bypass it.
I have seen people saying it is meaningless on a home network. Is this true?

I'm not talking about the 20% bandwidth myth.

Thanks in advance.

The larger the network the more relevant QoS becomes.

QoS is about assigning priorities to specific types of traffic and protocols (Eg TCP, UDP, IGMP etc)

I'd agree that on small home networks, it doesn't add much value.

I have 21 networked devices. My kids use skype and play lots of online games. They also do lots of downloads (game updates etc), and I run a Windows update server to keep all the PCs up to date.

My internet connection is not very fast.

Yet with all of this, the benefits of QoS are minimal, and I have experimented with it for some time.

Unless you give someone the password to your router, they generally cannot by-pass the traffic priorities you have configured.

...and i still beg to differ: QOS is essential for having the experience you want on your network. Thus, if you only have a few devices, there are are still immediately gratifying about shaping ones internet experience around their behavior.

I came here looking for more information about the necessity of this QOS Packet Scheduler (wondering if it added any value to its existence as an add-on for my network adapter), but it seems no one knows.

Was there ever a world where people explained the purpose of their software?

QOS is almost a necessity in a corporate environment where VOIP (Voice over IP) is used on networks with other network traffic. Voice doesn't require much bandwidth but it is critical that that small bandwidth is always available when needed. Otherwise there may be short but frequent interruptions making voice virtually unintelligible. With QOS that bandwidth should always be available. There are other situations with video over a network.

Such situations are less likely to occur in a home network.

Truth be told, the most significant adjustment I've made on my network (and my brother's network, who lives 2000 miles away from me---via TeamViewer) was adjusting MTU... That alone has cured error packets and provided a far smoother experience than I should probably have on my <2MB/<500KB (d/u) connection.

Regardless, yes, QOS was far more a hindrance on the direct connection I had three years ago (I move around a lot--for work and perspective lol).

Again, thanks for your input, TanyaC!
