QoS and Airport Extreme

I have a question that I posed to the apple tech support, but they were unable to answer or knew anything about QoS. It may not have been a fair question since it is not necessarily standard technology or may be patented by D-Link.

Looking at the AirPort Extreme, I was interested in using an Apple Product router with my iMac. I am currently using an Linksys G Router (old technology).

My brother is a Network Engineer, but he lives in the world of PC.

Anyway, I had a nice conversation with the Apple Tech Support, and the question about QoS is being forwarded to their Engineers as far as I know. So I pose the same question to this forum for some feedback or opinions on the Apple Aiport Extreme vs other manufactures Routers. I definately like the QoS feature since it does prioritize video signals and VoIP.

Let me provide you this example. Both my brother and I have VoIP (Vonage) so while we were talking to eachother over the phone, I was watching a video signal from his Slingbox (that I bought for him), so I could watch some good old Canadian Hockey "Live Streaming". We both have Internet Cable service.
Synopsis: The phone call was clear and not choppy. (Talking US to Canada)
The video was streaming live delivered with a Slingbox device and both (Audio/Video) were clear and not choppy- smooth! Why was this? How can such bandwith hogging applications perform so well. My brother explain to be that it has to do with QoS. Not totally dependant on speed of network.

What I did was copy a blurb from the D-Link website on their product "DIR-655"

Right now I am confused if I should return my Airport Extreme and purchase a D-Link Router.
Looking forward to read other people's thoughts.


WHY INTELLIGENT QoS IS BETTER
With some routers, all wired and wireless traffic, including VoIP, Video Streaming, Online Gaming, and Web browsing are mixed together into a single data stream. By handling data this way, applications like video streaming could pause or delay. With D-Link’s Intelligent QoS Technology, wired and wireless traffic is analyzed and separated into multiple data streams. These streams are then categorized by sensitivity to delay, so applications like VoIP, Video Streaming, and Online Gaming are given priority over Web browsing. This enables multiple applications to stream smoothly to your TV or PC.

I should have done this first. I searched QoS and if "Tesserax" is correct about their statement, then unfortunately QoS is not supported by the Apple AirPort Extreme.

Apple, do you hear me, THAT'S CRAZY!!!! This would make your amazingly awesome computers work THAT MUCH BETTER!!!

Let me know if Apple Products do something similar to what QoS. But it's crazy, the Apple people didn't even know what it was. I want to believe apple is on top of their game and is going to release a product that does address the QoS.
Steve, don't let us down. The iPhone is great, but don't forget the other products that got you to where you are!!!

Re: Does Airport Extreme Base Station support QoS

I would like to get a confirmation answer on whether Airport Extreme Base Station support QoS?

Unfortunately, no, it does

I am not sure if the cable or DSL supports QoS, but I would imagine it could if the manufacturer does produce it to support that standard. I think Vonage does also do QoS in their products now because it just helps the quality of the calling that much more. To answer the question you asked, it's best to check your product specifications. But because so many people are now doing home networks, the best BANG for you buck is to have QoS supported in your router since that is where the BOTTLENECK is going to occur in your network!

It appears that the router configuration settings are pretty basic in the Airport line. I prefer the Apple products to provide wireless, but use other vendor's routers to handle firewall and NAT (line sharing) functions. In fact, the Linksys WRT54GL (Linux version) is one of my favorites, inexpensive ($50), and has an array of Linksys and third-party software options. It has wireless B/G standards built-in, and you can toggle the wireless off if you have an Apple unit that does 802.11N. The QOS function lets you preserve a slice of your bandwidth for VOIP, and the SPI (Stateful Packet Inspection) Firewall is much safer than just using NAT IP masquerading.
There is really no reason that Apple does not provide these capabilities, since their Airport is probably based on their own software router code in MacOSX, which is based on Berkeley Unix (BSD). They just don't provide the user interface screens to configure it, and possibly don't want to test for several more complex setups in their quality control. But they really should have it, no excuse.

hey guys.

to summarise:
QoS is NOT offered on Apple routers.

so if you are interested in QoS (should be if your an advanced home user with a lot of network traffic) then your better to look at the Linksys routers.

if you already have an Apple router. check this out:
http://www.hawkingtech.com/products/productlist.php?CatID=36&FamID=80&ProdID=216
this little box adds automatic QoS to your network.
however I havent looked into it with much detail (not sure how it performs or how configurable it is)
