Video streaming often just needs a guarantee of sufficient bandwidth that packets are not lost. It's also often tolerant of packet delay and/or jitter. Do know, video streams are further often very bursty, so they need sufficient queuing.
e.g.
policy-map sample
class videoStream
bandwidth x (where x is set to nomimal bandwidth, plus perhaps 10%)
queue-limit y (where y is deep enough you don't see drops)

Video streaming - is Qos the answer?
We're having problem with a video stream we are distrubuting to a few users. Lately we got a lot of complaits regarding glitches/freezing in the video.
Hardware in 7600's: WS-X6704-10GE
Topology:
Incomming stream<<--port channel 2G Fiber-->>7600(SUP720)<<--10G fiber-->>7600(RSP720 SVI for video)<<--10G fiber-->> Switch<<-1G RJ45->>PC
- I've checked the interfaces on the 7600's but cant see any errors on the interfaces or output drops on the interfaces(no congestion?)
- We're seeing TX drops from the edge switch to the pc's. Investegating the cause with vendor. But my guess can be buffer problem going from 10G to 1G?
- We have not implemented any Qos on the 7600's however we have enabled qos to prioritize the video vlan on the edge switch.
- Peak traffic between 7600 and edge switch is about 1G(5min average)
- Would enabling QoS on the 7600 and do End to End Qos solve the problem? As far I understand qos will only help if the interface is congested which isn't the case here?
- What would be the best strategy for video streaming? Would the solution be to use the CBWFQ + LLQ for this kind of traffic or would LLQ starve the rest of the queue's?

Probably, and those drops could be the cause of your "...glitches/freezing in the video."
So, what you might want to first address is using QoS on egress edge ports to insure video traffic isn't dropped.
"...we have enabled qos to prioritize the video vlan on the edge switch."
Prioritized in what sense? Dequeuing priority often makes little difference for typical buffers depths at gig or better bandwidths. Priority avoiding drops, though, might be worthwhile. -
Help implementing QoS for Video Streaming
Hello friends!
I am trying to implement a quality of service logic for a videoplayer based on the Brightcove API. As I have learned it's a better idea to use methods in NetStreamInfo class (eg. currentBytesPerSecond) rather than using a native bandwith check.
E.g. (where nc is a NetConnection object)
var ns:NetStream = new NetStream(nc);
var nsi:NetStreamInfo = ns.info;
var cbytes:Number = nsi.currentBytesPerSecond;
use cbytes to evaluate which quality to chose...
The problem is that streams are initiated (by videoplayer) using the Brightcove API and not directly using NetConnection.connect(). The BC API doesnt seem to give me any access to the classes listed above either, altough I'm certain it's utilizing them.
Are there any Brightcove or video streaming experts out there that have a clue as to how I can access the NetConnection object used by Brightcove? Or if i can access the NetStream object or even tge NetStreamInfo object directly.
best regards,
FredrikYou don't have your egress queuing setup. You need to map your COS values to a queue, then you can allocate bandwidth to those queue's. This makes lower priority traffic wait while higher priority traffic gets transmitted.
I have a few configuration examples on my site that may help you. Remember that the config that I have may not be the best for your network so you will have to figure that out yourself.
http://goatnetworking.com/CiscoCSwitchQOSConfig.php
Make sure that your QOS profile on the WLC is set correctly. I found one of my controllers didn't even have a value set in the profile, but the profile was applied and doing nothing.
You need to apply the policy map to mark packets on the port where the video source is on your network.
You need to Trust DSCP on all of your trunk ports or the switch will ignore the dscp markings.
QOS may only be one of many issues that may be causing your problem. Your AP's could be overloaded with clients, your data rates may not be optimized, etc..
I hope this helps

QoS and DSCP settings for Video Streaming
So I've got this beautiful topology at home that consists of three WAP 121 and a RV320 as the default gateway.
How should I tweak their QoS and DSCP parameters to optimize Video Streaming applications like YouTube, Netflix and such?
Thanks community!Open the set up page of the router by typing the IP address of 192.168.1.1 or open Cisco connection go to router settings
Then go to advanced settings and then click copy password and hit OK ..once you on the router page
Go to wireless and click manual after that create network name (SSID) Then set the wireless security as WPA2 personal
Which would give you stabilize connectivity then upgrade the latest firmware on the router and reduced the MTU to 1462..
Unplug the power from the modem and the router
Wait for 1 minute and plug them back wait for 1 minute and then check the speed . -
Could someone point to the recomended priority of 750Kb of streaming video.
Thank you
MarioThe below links can help you.

Configuring QoS for FIOS Router MI-424WR: Traffic Priority and Shaping
Please only read on if you are an experienced internet user familiar with setting the advanced QoS and Firewall settings for the MI-424WR and make use of wireless adaptors from a PC to provide connectivity.
This is my first post and my first week since I moved from Time Warner Cable over to FIOS for iNet (plus HDTV and phone). While all my services work, the router as delivered and setup is not optimum for internet quality of service. Instead it was probably out of the box optimized for HDTV and telephone to satisfy most customers and reduce support overhead. The average FIOS consumer is multimedia sensitive, but that is not so in my genre of internet consumer. Here in lies the core of my reason for seeking help from like minded and experienced users in this community.
One of the main driving forces in my switching to FIOS was to improve my multiplayer gaming experience where ultra low ping latency and high upload data rates dramatically affect the quality of connection and thus gameplay. The cable internet service from TimeWarner was providing solid 2MB/1MB down/up data rates with no issues like what Im having now with FIOS. Again the reason for the switch was both financial and in hope of gaining better data rates and quality of service. Now with FIOS Im getting about 24/15 down/up data rate on the Extreme FIOS 25/25 plan when measured from my house to Los Angeles server (50 miles away) via Speedtest.net or DslReports.com/tests. Latency wise, the ping has gone down from 150 to 50ms when measured to my friends who I connect to online that are on the East coast. The data rate and latency has greatly improved in going from Cable to FIOS. So far, so good.
Where the problem shows up now, is that now I get an internet "hiccup" every 5-10 minutes that lasts about 1/2 to 2 seconds. For the average internet user that just streams multimedia or cruises on the net; this is probably undetectable or noticed. I never had this problem over the same PCs connected wirelessly to my DLINK DGL-4500 Gaming Router when my ISP was TimeWarner's cable service. Now, using the FIOS and MI-424WR router with everythings being the same; Im experiencing this degregation in quality of service. Even putting the PC's IP into the DMZ doesnt make any difference, so it is not related to port forwarding. The issue is squarely in the lap of FIOS and this router as delivered and configured. This is where the "game" is a foot, and where I need expertise in an area Im new to.
I am not new to being hands on with inet trouble shooting asI have been setting up my own home network (I work from home over VPN to work) for decades; I would like to leverage the skills of those who are experts in the area that I think can address this issue. That being QoS and the other device class mechanisms of this router. Its my guess that this periodic hiccup can be minimized and even eliminated using these advanced features of this all-in-one TV/iNet/Tele router.
With that context being laid down, this hiccup doesnt show up if:
a. I connect two PCs connected to the same ethernet hub of the MI-424WR (traffic just over the LAN and not WAN)
b. When I was on Cable with my own gaming router wirelessly DHCP connected to my PC and using port forwarding or using the DMZ.
The hiccup does exist when:
a. Going from internet through the MI-424WR to the wireless DHCP connected PC with port forwarding
b. Even putting the wireless DHCP connected PC into the MI-424WR's DMZ has no effect
I did read the manual and tried some QoS pritority and shaping and managed to reduce how often the hiccup occured, but I was just making guesses at the settings. I put in the IP for the PCs I use for my gaming applications (which are very ping and jitter sensitive) into the QoS priority (value 7) and shaping GUI. Im hoping someone with experience can tell me exactly how to use it and what settings to input. Im not clear on the device and connection types offered in the QoS menus.
Another thing, is I couldnt find settings for the turning on/off the ICMP echo. But I assume this is on because it can be pinged by folks on the net to my WAN IP.
Here is the manual for the Verizon provided M424WR router (Current Version of firmware: 20.10.7)
download link
Here are the QoS traffic priority and shaping values Ive been experimenting with:
Click to view QoS Traffic Priority
Click to view QoS Traffic Shaping
And why it matters to have a solid and stable inet connection for internet gaming? The hiccup causes slewing or jitter which equates to positional errors in the 3D world that ruins the smooth gameplay that is needed for high end gaming.
Heres a snapshot of me flying the wing of another flight simmer who is on the East coast and me on the West coast.

That's not accurate. VZ telephone service does not go through the Actiontec. Also, there are no default settings for QOS in the Actiontec since QOS is rarely needed with FIOS upload speeds.

You should not be experiencing periodic "hiccups". Something is clearly amiss.

Lets see. The issue shows up on a wireless connection, but not a wired connection. You think this is a QOS issue and not a wireless issue why? Have you tried changing the wireless channel? It very possible you have neighbors on the same channel. Is the DGL-4500 wireless still on? Could that be interfering?TMAS wrote:

The settting to enable/disable ICMP echo is on the Firewall/Remote Administration page.

The traffic proirity settings you linked are applied only to your wireless connections. QOS between the router and your wireless PC will only serve to prioritize traffic between the router and that PC and have no affect on your internet traffic. Assuming you are not running browsers, VOIP and other traffic from that PC while you're gaming, then that will not accomplish anything. i.e. You're giving your only traffic highest priority, but that traffic is not competing with anything (except other nearby wireless connections on the same channel).
On the traffic shaping screenshot, you have broadband ethernet checked, but according to your other thread, your WAN connection is Broadband Coax, not Broadband ethernet. -
Home Sharing Streaming with Apple TV Network problem - Solution
Was not able to stream video from my library in iTunes, able to select, but would not stream to play, I tried everything in the Apple Support Community
Setup: Windows 7 PC iTunes 11
AppleTV 3 generation v5.2

I change the settings for WMM on the Linksys WET610N.
What is Wi-Fi Multimedia?
Wi-Fi Multimedia (WMM), previously known as Wireless Multimedia Extensions (WME), is a subset of the 802.11e wireless LAN (WLAN) specification that enhances quality of service (QoS) on a network by prioritizing data packets according to four categories. Network administrators can change priority levels as they see fit. Ranging from highest priority to lowest, these categories are:
Voice: Giving voice packets the highest priority enables concurrent Voice over IP (VoIP) calls with minimal latency and the highest quality possible.
Video: By placing video packets in the second tier, WMM prioritizes it over all other data traffic and enables support for three to four standard definition TV (SDTV) streams or one high definition TV (HDTV) stream on a WLAN.
Best effort: Best effort data packets consist of those originating from legacy devices or from applications or devices that lack QoS standards.
Background: Background priority encompasses file downloads, print jobs and other traffic that does not suffer from increased latency.

Hope this helps someone, please let me knowUpdate
Also disable this feature on your router, the data packets are not being read correctly. Temporally while Apple figures this out.
Disabling WMM will just tell your router to stop regulating it, giving every bit of data transfer the same priority. Most routers come with it disabled by default, but some have it enabled by default as well.

Can Anyone Help Me Configure My Verizon (D-Link) DSL-2750B "Traffic Shaping" (QoS)?
Well ... I just spent a wonderful hour and a half (not) bouncing around VZ technical support, etc. trying to get assistance regarding configuring my DSL router.* Between the low-quality Skype connection to India and my lack of success, I'm a little bummed out right now.
Could one of you perhaps help me? I'm trying to configure a single, wire-attached network node (port 4 of the router) so that it can only consume up to 320 Kbps of my 750 Kbps (7.5 Mbps) DSL bandwidth ... no matter what. This results from this node consuming virtually all of the circuit's bandwidth when streaming or during bulk file transfers.
I have tried to remedy the problem using priority with no discernible impact.
The Quality of Service (QoS) element called Traffic Shaping (Services | QoS | Traffic Shaping), described on Page 51 of the VZ DSL-2750B User Manual , appears to be the ideal solution to my problem. Repeated attempts at activating this QoS have all resulted in no throttling of bandwidth consumption.
My most recent attempt was to define the device on Port 4 as the DMZ host ... and then apply a new rule (320 TX, 320 RX) to this interface. Again, no joy.
Does anyone have any experience with this service on this router?
Am I chasing my tail trying to configure the router without validating that my circuit is not configured with "Fastpath (PSE) inactive"?
If the circuit configuration is a potential problem, which office should I ask for at VZ customer service?
Here is the information from the System page of the Router Control Panel:
Gateway ID: PX2M1BC000000
Software Version: 5.4.12.1.44
Release Date: Feb 19 2012
Platform: D-Link DSL-2750B
Board Tag:... Ntag-5_4_12_1_44
Compilation Flags:... LIC=/home/bat/bat/dlink_bcm96328_5_4_12_1/20120219_1343/conf/jpkg_bcm9636x_dlink.lic CONFIG_RG_PROD_IMG=y DIST=DLINK_DSL2750B
I'll note that the Router provides a notification that "RX QOS might not operate when Fastpath (PSE) is active" when I update the router configuration page concerning Traffic Shaping. Because Fastpath is not mentioned in the User Manual, I'm guessing that Fastpath (PSE) might be a configurable attribute of the circuit servicing my PoP, but I have no idea if this is the case.
I searched for relevant messages on this board ... without success. If this has already been addressed, please provide a link, and accept my apologies. (My Google-Fu tends to be weak.)The asterisk in the first post refers to the following summary of events:
10:40 - Attempt to solve my configuration question using VZ chat begins.
10:49 - VZ chat agent Danish refers me to phone support. (Chat ID number is 020813176471 if you're with VZ and are interested.)
10:50 - Call VZ phone support.
11:02 - Talk with Angel. Because she has not heard of, nor received training in, "traffic shaping," she says my question about configuring this VZ DSL modem must be addressed by "Premium Technical Support." She transfers me.
11:13 - Talk with Pamela. Premium Technical Support only responds to questions about 3d party products. Because my question concerns a VZ DSL modem, Basic Technical Support is responsible. She transfers me.
11:17 - Talk with Joe. He says either the vendor (D-Link) or premium technical support is required. Because I had already tried with D-Link (they referred me to Verizon, as this modem was built exclusively for VZ), I explained what I had already experienced, and described how I wanted "assistance configuring my VZ DSL modem, specifically a feature described on page 51 of the User Manual." He transfers me.
11:23 - The automated phone system asks for my 12-digit customer ID. I wasn't able to find it fast enough, and rolled through to Financial Services. Eventually Trig picked up, listened to my story, and transferred me to "Technical Support" providing the direct dial number, just in case (866.945.79xx).
11:32 - Entered the phone queue. Lots of hissing and clicks.
11:35 - Talk with Monika. (The voice clarity from this point onward was on the order of 1st-generation Skype. Between the horrible language problem -- Monika is in India don'cha know -- and the lousy line quality, this was the most frustrating.) No matter what I said, I couldn't convey the reason for my call. I asked to talk with a supervisor, which Monika related was not possible. She also related that she could not transfer me to an American POC or supervisor.
12:01 - Hung up the phone ... and started down the path that led to my post immediately above.
I was repeatedly queried about the account name and number throughout the process. Conveying this information was especially challenging during the Indian call segment. -
Need advice with routers (gaming, stability, QoS?)
Hi.I use Sky Broadband for gaming. Unfortunately, my housemate has about 4 devices on the go at once and being an ignoramus has no idea what they are doing half the time... His Xbox may be downloading a huge update for a game he doesn't play, his iPhone and laptop may be uploading a load of pointless information to the iCloud and he may be simultaneously downloading a HD stream on Sky of some programme he's barely watching cos he's looking at videos of cats on his phone. Meanwhile, I often get completely locked out and lose connection to servers. It's infuriating. -_- Rather than get frustrated about it, I figure it's time I got a decent router with QoS that prioritises the stability of my ping so that these inconveniences can be a thing of the past and he can get on with his aimless downloading without myself getting annoyed. Unless I am mistaken, the Sky routers are all incredibly average and have nothing that can help (correct?) so I'm guessing I need to buy and plug in a second router (with QoS presumably?) into the Sky Hub and setup QoS this way? Can anyone advise me on routers that may suit this purpose (preferably under £100) and how I would go about setting it up? Thanks in advance.Matt
An update from me. I bought the TP-Link AC1750 as recommended. Before installing it you need to download the latest firmware to your PC because it doesn't work without it. I used the disk to install it though I may have needed this information (I can't remember if it did it automatically or not but it's handy to have it in front of you just in case you need it): Username: [email protected]
Password: install
Connection Type: PPPoA
VPI: 0
VCI: 38 After installation go into your router (192.168.1.1 in browser, user/pw: admin) then system tools>firmware upgrade and install the firmware. The QoS works like a BEAST. Completely neutralizes annoying flatmates. You just have to give your PC a static IP then go into the 'Bandwidth Control' menu, allocate yourself priority 1 and guarantee yourself some medium-high download/upload speeds. I did, however, find the wifi still caused me issues - the 5Ghz was virtually useless through walls and the 2.4Ghz had too many neighbour's routers overlapping causing lag. My final step was to buy a set of POWERLINE ADAPTERS. TP-LINK TL-PA4020PKIT AV500 to be exact. Easy to install. Since the day these were installed I have not had 1 single lagspike. Not 1. If you're on Sky and a gamer, this is possibly the best setup to avoid lagspikes. It certainly is for me. The router cost about £95 and the adapters cost about £39. You might be able to find them cheaper if you look around though. (Sorry if this is patronising or not aimed at anyone specific, I'm just leaving it here for future googlers in a similar situation and looking for a fix to save them all the hours I spent googling to collect all this information). -
Query related to QoS Telepresence
Hi All,
Wonder if someone has experience on QoS configuration specific to CTS Telepresence and able to answer on my below query :
I am trying to understand how can we check the QoS configuration applied on CTS's :
- If I go to Telephony settings in CTS, it gives me :
DSCP For Audio: EF DSCP (101110)
DSCP For TelePresence: CS4(precedence 4) DSCP (100000)
I was under impression that CTS's get this settings from CUCM clusterwide setting option, but I came across another client CUCM where clusterwide setting was AF41 for video but CTS's still reflecting the above settings , any idea from where the CTS derived these settings and how can we edit it.
The other question is , I was capturing the call statistics for a P2P call between two CTS's , I am trying to understand what these logs states :
2013-12-18 11:26:38: INFO Audio DSCP Current Marking: [BE], Previous Marking: [BE]
2013-12-18 11:26:38: INFO Audio COS Current Priority: [0], Previous Priority: [0]
2013-12-18 11:26:38: INFO Video DSCP Current Marking: [BE], Previous Marking: [BE]
2013-12-18 11:26:38: INFO Video COS Current Priority: [0], Previous Priority: [0]
Does it mean, that local CTS is running on QoS Best effort settings ? Both these above and below logs represent local CTS QoS Status or giving information about remote CTS QoS settings also ?
'cos when I go to log files, I get this information , but if I go to Call statistics for the same call, I get the below info :
Audio/Video Call: Audio Stream Statistics
Local : [IP Address removed]
Remote : [IP Address removed]
Average Latency (Call) 2
Average Latency (Period) 2
DSCP Current Marking: [BE]; Previous Marking: [CS4]
CoS Current Priority: [0]; Previous Priority: [4]
And, that's same for Video stream Statistics.
Can someone please try to shed some light on this and help me in understanding the actual behaviour .
Thank you.I posted it on both the forums with the thought that different people view and address them..... :-)
I thought you directed me to the answer, but sadly, it was my post on different section of this community. -
I am trying to test and document the performance of QoS. I have an E3000 with firmware version 1.0.04.
I have tried various traffic generators (like Netperf), and settled on D-ITG; It can send, receive, and report on many different traffic streams.
I have set up QoS rules on the E3000: port 12865 Low priority, port 12875 High priority. The traffic flow is from computers on my LAN, through the internet port on the router to a WAN addressed computer in the same room.
Cisco documentation states that QoS works only on "upstream" traffic, hence the particular traffic flow.
My problem is that the QoS appear not to prioritise when enabled.
Stream 1 on port 12865 achieves ~45Mbps, stream 2 on a seperate computer simultaneously on port 12875 achieves ~45Mbps also.
I have tried both TCP and UDP traffic.
Can anyone suggest why? Has anyone else found issues with QoS?Do you have a similar set up? Can you tell me how you have approached the problem? Have you got any different results?
-
Ooo err. QoS nose dived. Anyone else?
Is there a problem with the QoS atm?

This test was not conclusive and further testing is required.This might be useful for your ISP to investigate the fault.
The QoS has been in the region of 5000 Kbps for some time now.....
-+-No longer a forum member-+-(would of replied last night, but the waiting for the page took too long)
Hi Guilbo and thanks for the reply
Good point, they may of finally got their 'ears' in gear and sorted it out.
I too have been having QoS results that exceed the max of 600 Kbps and 1600 Kbps (the latter, as you know, when VOD has been watched).
Last night (after you posted), the speedtest results after watching a Vision help video was in the 4200 Kbps region.Will the upper limit be tweaked to represent the higher result or will the speedtest start to max out at 1600 Kbps? I guess only time will tell.....
Today with no VOD being watched, the result is 618 Kbps, so slightly over the 600 Kbps acceptable range.
So for now, all seems well.....

QoS removed from line :@ Getting to the point of c...
Hello,
After a week of getting BT to fix my BT Vision service which they did and enabled QoS.
I am ****** off to say that the QoS has been removed from our line and again we cant watch anything at all On Demand without the dreaded VO4 error!!
It's getting to the point of us jacking in the TV package and go to Sky for TV services unless it's fixed within the next 48 hours...

ThanksThere is an issue with BBC iPlayer software update which has buggered up the box
It isnt very stable at all, it's all well and good having iPlayer but if it doesnt work properly I want the new version fixed or the old software back and lose access to BBC iPlayer.
Nothing wrong with the QoS at all- I have had to factory rebuild the software 5 times since the iPlayer update on Thursday morning, box keeps locking up and if you rewind/ ffw anything on demand you get VO4- wasnt an issue before the iPlayer release.
The box is about the same speed as the antiquated Scientific Atlantic V+ HD Box which is slow... -
Netflix streaming affects network ping
I know that it sounds crazy, and I've been trying to fix it, but when I stream from netflix (HD content only) the ping times of my network will jump to about 600-900ms (from 40-ish ms) every 10 seconds. Very goofy! I've tried doing the same thing from my blu ray player, PS3, iPad, iPods, and a couple of laptops. No problem, BUT when I use the Apple TV (1080p version) this is even over Ethernet and not Wifi. I have another AppleTV (720p version) that is over WiFi and it affects the ping times too. Everything is ok, but these screwy ping times make certain online games challenging or unplayable. The second that you pause or stop the stream ... boom, fixed.
So, only NETFLIX, and only HD content. This doesn't occur on my home media center, or with HULU, or streaming from iTunes. WHAT???? Any ideas?

Happy streaming!!
