GOPHUR, not a bug but need to know which program is wwiiol

[Sudden]

Short story.

I want to use my router's QOS settings to give wwiionline priority when it is running. I need to know the name of the file to give this priority to.

Thanks

[Sudden]

In case anyone is wondering why...

I'm flying now and every bit of connection is needed. I knew about this setting for a while now but never used it. If I can't prioritize the file, I will just prioritize the hard wired gaming computer of all the wireless devices in my house.

Asking KFSONE to comment. above my pay-grade.

Pretty sure he'll say QOS is CRAP but not sure.

I don't understand what you're trying to configure that would be interested in a file name unless it is something on the actual PC running the actual executable, and then a quick glance at taskmanager would tell you that it's WW2.exe.

My ( limited ) knowledge of QoS suggests that it would be based on IP ranges and ports, in which case a quick glance at the faq firewall stuff would tell you TCP/UDP port 27015-27021 to/from addresses 66.28.224.128/25 and 209.144.109.128/25.

But what the article you linked suggests is that you need the Mac address of your gaming PC, and not some filename. You'll need to get that from your local computer.

But then again, I don't believe you've described a situation that benefits from QoS. WWIIOL is not a streaming app, it's very unlikely that your router is congested with traffic from WWIIOL.

Well configured QoS will:

- prevent apps like Java, Adobe, Flash, etc from killing your game connection by running their "I know you disabled auto-updates but we're going to download auto-updates to see if they exist" update,

- prevent BITS from doings it's job, just like if you disabled the service,

But mostly, QoS will:

- change the way lag/network outage issues appear on your computer, making them difficult to diagnose,

- cause non-prioritized apps to increase CPU usage,

- cause failures of important network services like DNS etc that the app is relying on,

- increase the CPU load on your router and reduce it's performance reducing your throughput,

- cause your ISP to drop/disconnect you due to lack of responsiveness to various control packets.

My home Lan is on a gig backbone with 3 discrete switches and a router, a Windows Server 2008 R2 domain controller, an Ubuntu Orchestra server, a distributed build system, plus laptops, PCs, xbox, smart phones, kindles, etc.

Oh, and I forgot to mention - a WWIIOL game cluster

QoS = Quality of Service. It lets you tag certain packets as being more important than others.

The concept is simple: if I have two packets waiting to be sent, instead of sending them in normal first-come-first-serve order, check their priority.

If you don't have two packets waiting to be sent, then it has no effect -- which is the normal case in most home networks because the home-router is able to offload packets to the isp-modem much faster than the modem can offload packets to the ISP.

QoS doesn't/can't interrupt a low-priority packet being sent in order to force the transmission of a higher-priority packet: it only has any effect when your router is congested and packets are queued up.

It does, however, force the router to perform additional stateful inspection of every packet that it handles, which uses router-CPU, and given that most routers run at 200Mhz or less, that's quite an overhead.

There's one last quirk: Most home routers/switches delay all non-priority packets by a factor of Nx lowest-speed-port-time-to-receive-a-network-frame - i.e. if you have a 10Mb port connected, then N x 8 microseconds.

Remember that these routers tend to run at 200Mhz, the value of N is usually quite high, delaying all non-QoS packets for upto 2-10 milliseconds.

This gives the router the opportunity to forward bursts of high-priority QoS packets without always finding the ports congested with outgoing low-priority packets.

For my home network, I squeezed a little extra juice out of the connection by replacing my LinkSys firmware with TomatoWRT and overclocking to 250Mhz

Thx kfs1,

The article was just the first one that popped up so I used it as an example.

I want to prioritize my gaming computer over any other device that might connect to my wireless router. The gaming computer is connected directly to the router. The IP of that computer now has the highest bandwidth priority of any device that may connect to the router.

The reason for the file name question had to do with something I read about qos being used to prioritize a single application for bandwidth allocation. That's all.

There is probably too much detail but here's where I get my info.

Rookies, Don't try this at home! You can brick your router.

These are the specs for the router I have now (if it matters).

RT3052, 384MHz embedded RF/MAC/BBP

Gigabit: Realtek 8366SR/RB

Memory 32MB SDRAM (16 + 16; enhanced performance)

Flash 4MB

Thanks for the information. This is what I was looking for.

When you're using two separate interfaces like that, QoS is going to kick in when the router has simultaneous activity on all three intefaces (wan, lan, wl0). Having harvested packets from all interfaces, QoS may result in prioritization of your gaming packet.

However, the benefit of QoS is going to be offset by the cost of QoS, which is that each and every packet requires stateful inspection by the very-slow router CPU: all packets are going to be spending much longer at the router in the first place.

Remember: QoS is really about streaming, 10-90ms extra delay on a VoIP stream is a perfectly acceptable cost for a smooth, non-stuttering stream.

Overclocking your router slightly can make a big difference - 200Mhz-250Mhz on my border router made a huge difference to the home network.

In my router I have my gaming computer as priority1

Congratulations, Sudden, you have managed to entice Oliver to post more text in this one thread than I have seen him post in over 5 years here. He's an interesting guy, click the blog link in his sig if you are interested in programming stuff. I go there from time to time and have both learned some odds and ends as well as come away with things to think about.

Anyway, I think that the point is that he told you that QoS is somewhere between useless and evil except in the context of pure streaming like VoIP which is pretty much what I've always heard. I am a simple developer and don't deal with network plumbing, but can recall when we attempted to improve the performance of a client/server application between the US and UK by giving priority to the app's packets and it didn't do a damn thing. That was using Cisco enterprise routers, so I'd be surprised if you don't actually take a hit using some home kit.

Anyway, I'm glad you drew him out and posting.

[Sudden]

All good info. Bottom line for me is that I can try it and see what happens in-game. I'm more interested in throttling everything connected by wireless but I don't want to make it permanent, just active when I'm gaming here. qos seemed like an option.

[GOPHUR]

Glad I could help.

[rubbish]

So qos is of no advantage, but is port forwarding still worth the effort?

[GOPHUR]

You should only need to port forward if your router is blocking the port.
