QoS for Video Data

Hello Together,
I like to implement a QoS Policy class to prioritise "Windows Netmeeting". Does somebody know the well known port number and can somebody recommend an bandwidth that i should provide at least to this class ?
Thanks in advance.

As you can find in the Netmeeting IP ports table below, netmeeting uses dynamic ports for Video streaming. So I am not really sure how you can configure QoS for the same.
Anyone has a good tip to achieve this.?
Port Purpose
389 Internet Locator Server (TCP)
522 User Location Server (TCP)
1503 T.120 (TCP)
1720 H.323 call setup (TCP)
1731 Audio call control (TCP)
Dynamic H.323 call control (TCP)
Dynamic H.323 streaming (RTP over UDP)

Basic qos for video using mqc

I have two 2800 routers connected via T1. I need a basic configuration for prioritizing my video using MQC and LLQ.
Thanks.

Hi,
you have to build only 2 priorization-queues. One for Voice and one for Video (with lower performance).
The third queue will be a wfq-queue with lfi to be sure that big-packets are not reasons for bad voice or video.
the signalling should be in the voice-queue.

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,
Fredrik

You 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 for video conference

Hi,
Can somebody help me design the best way to configure qos in the following scenario? and where to apply the qos policy?
Central office:
2600xm router and Polycom video conference device
Remotes:
2600xm router and Polycom
Note: The remotes are connected using a ipsec tunnel from pix to pix and the 2600xm is in the inside doing GRE to the main router which is a 3660 which is connected via a ptop t1 to the location where the other 2600xm is.(2600>pix>pix>3660>2600).
Thanks very much,
Uriel.

I think this documents give a good idea about the QoS requirement in a video deployment .

Using 3750 switches & 2821 router for video & http qos

Hello all,
I know that the 3750 switches and 2821 routers are aging platforms, though, was curious if it they are capable of providing QoS for video (such as WebEx) and HTTP/HTTPS, in addition to voice traffic?
Thanks

Thank you Reza.
One reason we're looking into this, is that we wanted to see if we could give priority to traffic destined for, and arriving from, certain servers (in addition to certain classes of traffic). Is that possible? Most of our switches have IPBase images (12.2(55)SE1).
Thanks

Qos for H323 Video tele conference traffic

Hi All,
I am using Tandberg video equipment(bridge MPS200, endpoint MPX2000, MPX6000). My WAN routers are Cisco 2800/3800 connecting to MPLS network.
Jitters are between 4ms - 20ms. Picture quality is not very good when I use the bridge calls out to 8 endpoints at 384Kbps.
would you put audio and video traffic into the same class and mark it as EF, or seperate them with marking RTP audio as EF and RTP video = Ip precedence 4?
thanks
PH

Just for the record
The Cisco Enterprise QoS SRND reccomends putting Video AF41 in the PQ.
1st ref 3-12
policy-map WAN-EDGE
class Voice
priority percent 18 ! Voice gets 552 kbps of LLQ
class Interactive Video
priority percent 15 ! 384 kbps IP/VC needs 460 kbps of LLQ
class Call Signaling
bandwidth percent 5 ! BW guarantee for Call-Signaling
class Network Control
bandwidth percent 5 ! Routing and Network Management get min 5% BW
class Critical Data
bandwidth percent 27 ! Critical Data gets min 27% BW
random-detect dscp-based ! Enables DSCP-WRED for Critical-Data class
class Bulk Data
bandwidth percent 4 ! Bulk Data gets min 4% BW guarantee
www.cisco.com/go/srnd
When provisioning for Interactive Video (IP Videoconferencing) traffic, the following guidelines are
recommended:
? Interactive Video traffic should be marked to DSCP AF41; excess Interactive-Video traffic can be
marked down by a policer to AF42 or AF43.
? Loss should be no more than 1 %.
? One-way Latency should be no more than 150 ms.
? Jitter should be no more than 30 ms.
? Overprovision Interactive Video queues by 20% to accommodate bursts
Because IP Videoconferencing (IP/VC) includes a G.711 audio codec for voice, it has the same loss,
delay, and delay variation requirements as voice, but the traffic patterns of videoconferencing are
radically different from voice.

QoS config for Video Traffic

Hello all,
I have a campus network with several remote sites, at the campus I have a 6509 at the core and 3560 and 3750 switches at the access layer. I do have QoS enable on the 6509 and I am using auto QoS on the 3560 and 3750 switches and all seems to be working fine with my existing VOIP environment. But now as I am in the middle of rolling out a video conferencing solution with the existing QoS config I am experiencing a noticeable delay between audio and video. Example like during a video call I can tell that the voice and the lips of the person speaking are not in synch.
Has anyone run into this issue ? can someone provide me a sample QoS config for the 6509 and 3560/3750 switches ?
P.S. I am using a Tandberg/Codian solution for video conferencing with Tandberg/Codian MCU, IP Gateway, ISDN Gateway and Tandberg endpoints. And both the endpoints and the back-end infrastructure devices and are set for IP Precedence 5.
Thank you very much in advance !!!
Danny

The main concern with configuring your back-end infrastructure devices with IP Precedence value 5 is that the 3560/3750 auto-qos will map this value to Q1 which is ordinarily the strict priority Q.
In most cases auto-qos will also configure or map Video to Q3, you can see this as a majority SRR bandwidth is assigned to the Q.
In order to use the strict priority queue, it has to be enabled on the interface 'priority-queue out', without it Q1 will not be emptied before the others. It will be serviced according to the weight.
With auto-qos Q1 will not have enough bandwidth as it will be assigned to Q3. Therefore you could initially enable priority-queue if not already enabled so that Q1 is emptied first, or you increase the weight.
The next question is whether you are using egress scheduling within the Core? and this conforms to your edge classification for Video?
HTH.

QoS - Why DSCP AF-41 for Video

Guys,
I wanted to ask the forum one question why DSCP AF-41 marking is used for Video. I know Cisco designed and recommedded it in that way, but is there any other technical reason behind it?
Cheers,
Sugata

Hi Sugata,
Firstly as you may know already, traffic marking are done to classify traffic into different classes according to the priority so that they are meted with a different behaviour. It ensures smaller and critical traffic does not get stuck behind bulkier traffic which may not need priority.
Among the real time traffic, audio is the most critical. The Cisco recommended markings are according to the priority of the traffic type. Voice has a higher priority than video. Video is further separated into two categories - Interactive (Video conferencing etc.) and Streaming (playing a unicast or multicast video). The order of priority and reason for that is below:
1) Audio - Voice traffic is very sensitive to packet loss, latency. It requires no packet loss and latency of about 150 ms.
2) Interactive Video - Sensitive but can tolerate packet loss of about 1% and latency almost same as voice
3) Streaming Video - Less sensitive - can tolerate about 4-5% packet loss and latency of about 4-5 seconds
So it’s a general guideline\standard from Cisco to mark voice with a dscp 46 or ef, Interactive video 34 or af41, Streaming video as dscp 32 or cs4. Since this is Cisco recommended best practise, Cisco's most UC apps by default mark the traffic like this.
You can change it but strongly not advised unless you have a very good reason. Another reason not to change is some of the auto templates etc. you can normally use at access level catalyst switches use these markings, which otherwise you will have to manually change the mappings etc.
Hope this clarifies - if you have any further questions please feel free to ask.

Does the Music Store have a place for release dates on TV shows and videos?

Just wondering if they will have any idea when they will get new episodes of various shows they carry.I have heard it takes 24 hours for them to get them but I have come across about five shows that have episodes that are well over 72 hours and still not released.
Do they have a guide for release dates?Or a website that shows when they will carry certain episodes of shows?

yeah, you're right. I got an email yesturday from iTunes stating pretty much just that. I complained that they weren't getting my SG1 and SGA shows up on time. Anyway, I was an idiot for blasting them. We pay iTunes bills...not some advertisers...so they will deff get the shows out to us when they get them from the studios. Moreover, the email stated that they'll let sci fi (i'm assuming that's the network we're talking about here?) know to send those recent epps. BTW, I also posted this info on the sci fi board.

URGENT: QoS Design on Data Center MPLS - MediaNet Question...

Hello,
I am posting this in hopes I can get some guidance from anyone who has done this in the field. We have a large enterprise customer with 21 sites all around the world, they have Verizon MPLS and are experiencing QoS related issues on their WAN regarding Video/Voice. We have proposed remediating their network acccording to the Enterprise QoS SRND 3.3 and the new MediaNet SRND to account for Video and TP QoS (
http://www.cisco.com/en/US/docs/solutions/Enterprise/WAN_and_MAN/QoS_SRND_40/QoSCampus_40.html )
Here is the problem/question that was proposed in our presales meeting and I honestly don't know where to look for an answer... I am not asking for anyone to design a solution for me, just merely point me in the right direction:
The Data Center has a ~40MB MPLS Connection ( full mesh ) into the cloud ( Verizon )
Site A has a 8MB connection
Site B has a 4MB connection
I know on the Service policy and the interfaces at SiteA and SiteB I can assign "Bandwidth xxxx" and use ~95% of the bandwidth to do queuing and shaping/policing ect. I am not concerned with SiteA and SiteB, that I think I can handle...
Question was posed from the customer, "How can we ensure at the DataCenter level the 40MB MPLS is "chopped" up so that only 8MB of the total speed goes to SiteA ALONG with an attached QoS policy designed for that specific site, as well as ensure only 4MB goes to SiteB with an attached QoS policy.
So I am looking for a way to allocate bandwith per site on the DC 40MB connection going into the cloud ( so that SiteB cannot use more than 4MB ) and attach a MediaNet specific QoS Service policy to that site. The customer does not have seperate MPLS circuits for each site, they all come into the DC on 40MB shared ethernet connection ( no VC, or dedicated circuits to other sites ).
Any thoughts on if this is possible?
Thanks!
Alex

This is an example I have seen and I hope that is useful to you.
Site A
Subnet: 172.16.1.0/24
Site B
Subnet:172.16.2.0/24
HeadOffice:
ip access-list extended Site_A
permit ip any 172.16.1.0 0.0.0.255
ip access-list extended Site_B
permit ip any 172.16.2.0 0.0.0.255
class-map match-any Site_A
match access-group name Site_A
class-map match-any Site_B
match access-group name Site_B
policy-map To_Spokes
class Site_A
shape average 8000000
service-policy Sub_Policy(Optional)
class Site_B
shape average 4000000
service-policy Sub_Policy(Optional)
class class-default
shape average 28000000
service-policy Sub_Policy(Optional)
Interface G0/0
Description To MPLS cloud
bandwidth 40000000
service-policy output To_Spokes
interface G0/1
Description To HeadOffice
bandwidth 40000000
service-policy output To_Spokes
It would be greatly appreciated if someone can correct this or improve it as I am still learning.
Please see the netflow graph from one of our routers using a similar policy as above.

QoS for App-V

Hello,
I'm currently configuring new 3750X switches.
I must implement QoS on the stack. The QoS must be the following:
VOIP Class (50%)
App-V Class (40%)
Movie Class (10%)
How I can do this (in particular for AppV)? I do the following for the moment:
class-map match-any VOIP
match protocol voice
match dscp ef
match protocol sip
match protocol skype
match protocol rtp audio
match protocol rtp video
exit
class-map AppV
exit
class-map Movie
match protocol rtp video
exit
policy-map BandwidthTraffic
class VOIP
priority percent 50
set dscp ef
class AppV
bandwidth remaining percent 40
class Movie
bandwidth remaining percent 10
interface Gig1/0/3
ip nbar protocol-discovery
service-policy input BandwidthTraffic
Anyone can says me if it's correct or not? And why?
Thank you for your help.
Florent

It appears you've some router QoS. 3750X QoS is quite different for egress as you're limited to working with four egress queues. I don't recall 3750X supporting NBAR.
Suggest you read the configuration guide's chapter on QoS, for you 3750X IOS version, and then post questions as necessary. (My concern is, 3750X QoS is so different, it wouldn't be helpful to suggest a QoS configuration until you had a basic understanding of the 3750 QoS architecture and features.)

Optimum Settings for Video Streaming (Netflix, Sling, etc) with E1500?

I recently started using an E1500, which, for the most part, has worked great. However, my Roku devices no longer connect at maximum speed/quality, according to the connection gauge. I no longer get the HD indication. The highest I get is 4 dots. With my Panasonic Netflix software, where there is no specific HD indicator, just a horizontal bar, it is always one notch shy of max. With previous routers (Dlink, Actiontec, 2Wire) I had no problem connecting at the maximum, even with "G" connections.
So, I was wondering if there were settings within the E1500 that would optimize video data transport. I do have WMM enabled. I also added the Roku boxes to QOS. But, I am still getting less-than-maximum connections with Roku and Panasonic Netflix apps.

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 .

Why does itunes say that my iphone has 9GB of video data even though I've deleted every video I've ever made

Hello,
When I use itunes on my macbook to view the contents of my iphone 5, the bar at the bottom of the window that shows me how much data is taken up for different categories says that I have 9 GB of video data. The thing is, I deleted all of the videos that I've ever recorded on my phone, but itunes still says I have 9.15 GB of video data! I ejected my iphone and plugged it back in multiple times to see if it was a problem with refreshing, but that didn't work. Itunes also says that I only have about 3 GB of free space left and when I go to the settings on my iphone, it says the same thing, so I know that there really are mysterious files on my iphone taking up 9 GB of space. Also, both itunes and my iphone says that I have 83 video files. I've deleted as much apps as I could, just incase there were apps that had video files included in them, but that didnt really work. I also opened the video app in utilitties on my iphone and it said that I do not have ANY videos. I don't really know what else to do.
Is there any way to just see all of the files on my iphone? Itunes does not let me do that. It only lets me view certain files from apps like adobe reader. I need to find out what video files itunes is detecting on my iphone. Again, I've deleted all of the videos that I made on the phone by using the photos app. I never downloaded video files from safari either.
Thanks in advance

since moving to the mac from windows, this seems to happen less. I also found that having some videos marked as "remember playback position" resulted in a lot of updates to the ipod when i had watched them through itunes.
