I was wondering if the DNS-321 has the QoS tagging support feature and if not could it be added in a future firmware upgrade like the DIR-615 REVB F/W 2.25 with the added QoS engine?

[ECF]

What feature are you referring to? QoS should be handled by the QoS engine of the router that supports QoS. A device like this would not need an extra feature as QoS tagging.

802.1Q is traffic shaping and is usually only included in Corporate Hardware.
As for QoS, it's usually on the gateway device and in most cases only affects outbound WAN traffic.

[alan3885]

Is this feature on the DNS-321 or can it be added?

[ECF]

alan3885

What feature? Where you referring to 802.1Q in your first post?

[Praxis]

The DNS-321 does not come with the QoS feature, just remember that QoS refers to Frame Relay, Asynchronous Transfer Mode (ATM), Ethernet and 802.1 networks, SONET, and IP-routed networks that may use any or all of these underlying technologies. At this point the main idea is to configure your router and your network environment  including dedicated bandwidth, controlled jitter and latency (required by some real-time and interactive traffic), and improved loss characteristics. The DNS-321 will be included in your network with this feature.

So QoS will be included in the DNS-321 I'm confused?

QoS is a gateway implementation.

Actually I think is an interesting question ...

Whilst QoS is usually viewed in a network context as a method of providing priority to certain types of traffic (to guarantee the quality of service), it does have a parallel when considering a NAS such as this one.

With QoS priority is given to - voice and video (interactive media & voice - priority level 5) and streaming multimedia (priority level 4) with business critical coming in at a lower level (priority level 3).

Let's consider a scenario where the AV server is in use - streaming video to whatever device the user has - and a second user starts a file transfer - which of these services will be given priority - the file transfer, the AV server or neither?

My guess is the answer is neither, but is that how it should work?  Would the file transfer take noticeably or (significantly) longer if priority was given to the AV server (both as a process and as traffic overthe LAN port)?

Food for though - eh?

And now a disclaimer - I'm not into multimedia etc., don't use the AV server and in fact, I'm just looking the the original poster's question and guessing as to why he might have asked.

[Lycan]

Fact is, we do not offer traffic shaping or QoS on our LAN side devices, unless you're talking about switches. Even then it's a gateway device. As for protocol prioritization, we can ask. Odds are they'll say it's unnecessary.

[alan3885]

I just remembered the Linksys NAS200 has this feature also.

[fordem]

I'm thinking you must NOT be talking about QoS as it is normally discussed - I took a look at both the spec sheet and the manual for the NAS200 - the term QoS appears in neither.

Check out this version info for the Linksys NAS200 version 3.4R75:

3. Updated Media Server with QoS tagging support.

Does it really matter when connected to a Gigabit network? I've got two 80GB drives in RAID1 mode. When I ran benchmarked connectivity to and from the drive, I managed to reach 12% maximum usage of it.

If I'm doing the math correctly, 12% o***igabit = 120mbit. Divide that by 8, and we get 15MB (megabyte) per second. Sounds like having the need for QOS is a moot point, is it not?

That seems to be only for the UPnP AV media server while streaming.
