Bandwidth remote vs bandwidth interzone

The gatekeeper configured one local zone and one remote zone. We will use gatekeeper bandwidth CAC for controlling the number of calls from local zone to remote zone.
In this case, which bandwidth command I should use. Bandwidth remote or bandwidth interzone? Is there any difference between those two commands in this case?
Thanks,
JJ

So in my case, I can also use bandwidth interzone command instead of bandwidth remote for controlling the number of calls between the local zone and the remote zone which is configured on a remote gatekeeper? see the following:
Gatekeeper
zone local localzone cisco.com
zone remote remotezone cisco.com 10.10.10.1 1719
bandwidth interzone localzone 128
no shutdown
Is it correct?

CAC complex scenarios - please help!!!

I have read the CAC section of the SRND and I think I'm still confused on certain sections of the document. Would greatly appreciated anyone help on this :-)
Just assume RSVP is not a feasible option for now...
Re: Diagram 1
i) In this scenario, how many CCM clusters would you have & why? Would you put a cluster to each hub and remote site (i.e. to all sites)?
Ii) If each site has it's own cluster, how many GK would you use and why?
Re: Diagram 2
Iii) Assume it is a "Centralized model" where the HO hosts the only CCM cluster, do you see any problems in terms of CAC?
Iv) What would you configure for the location for the Non-GK controlled trunk between hub office (site D) & HO (site G)?
V) Do you ever configure any locations for the HO site? Or just leave the HO phones and HO Intercluster trunk as "none"?
Vi) Say if site A makes 7 calls to site B, and if site C also makes 8 calls to site B simultenously, can site B still call HO? I think the answer is no. Location CAC is not really designed to support multi-tier environment? anything we can do to fix this problem if the scenario has to be in Centralized model?
(N.B:- I have changed the location to be 'number of calls' rather than 'bandwidth' for simplicity)
Re: Diagram 3
Vi) In the centralized model,.If we have to reserve a certain bandwidth along all links end-to-end by RSVP, how is that differenet from using CAC? Don't we still need to over-pump the links? Say if a certain path along the RSVP path reserves 60 calls, wouldn't we need to RSVP for 60 calls through the whole path just like CAC?
Re: Diagram 4
Vii) For Tail End Hop off, assume all the voip dial peer has been setup on all the VGs, and the Route Pattern at Centralized CCM has been setup to point to the local VG (at site G) as Route List. But If the bandwidth between the hub (site D) & HO (site G) are all used up, but I want the user at site H to still be able to call the PSTN, can I use AAR in this scenario?
Thanks!

Hi thisisshanky,
Re: Case 1 (Diagram 5)
i) At Hub (site D), shall the 'locations' for the 3 x Non-GK intercluster trunk be left as 'none'?
ii) For the 'locations' for GK Inter-cluster trunks, shall they be set to 'none' as the traffic passing thru the GK are already being managed by GK already?
iii) If Hub (site D) wants to make 30 calls to site E, F, G & H at any time, would the total interzone bandwidth for ZoneA be 70 calls?
iv) Now, assume Zone B (site E, F, G & H) only needs to make 20 calls in total back to Zone A at any time, but since Zone A needs to make 70 calls as per iii, what should we do at GK?
bandwidth interzone ZoneA '70 calls'
bandwidth interzone ZoneB '20 calls' (would this restrict ZoneA to only be able to make 20 calls to Zone B?)
Re Case 2:
Can you please explain more on what problems will be faced since you mentioned it is not a true hub & spoke?
Re Case 3:
Can anyone else please shed some light on RSVP?
Re Case 4:
I'm a bit confused between the difference between the following 3 ways of setting up PSTN fallback if WAN bandwidth is insufficient in GK scenario
Say I want to call extn 3xxx on the remote office. The intercluster prefixs are *801, and the PSTN digits for the site is 9231-3xxx.
Method 1:
Configure a route list that contains two route groups. The first route group contains the intercluster trunk that routes outgoing calls over the IP WAN. Second route group contains the Voice Gateway.
Method 2:
Just on the Voice Gateway:
dial-peer voice 1 voip
destination-pattern 8013xxx
session target ras
preference 0
dial-peer voice 2 pots
destination-pattern 092313xxx
port 1/0:23
preference 1
Method 3:
Use AAR
Another extra Q regarding bandwidth for GK.
According to Cisco SRND, GK uses double the bandwidth as the codec call rate, so...
G.711 - GK uses 128kbps
G.729 - GK uses 16kbps
However, this is excluding all Layer 2, IP & RTP overhead... so when i am planning for number of calls, what values should i use as 'bandwidth per call'?
Cheers,
Hunt

Proper bandwidth for a remote standby db

We'd like to setup a remote managed stdby db on 8.1.7.4 solaris 2.8. Our line will be 768kps with bursts up to T1.
Is that enough? If not, what would be the optimal?
Jason

1) I'm assuming this is a dedicated connection-- you're not going to have database replication traffic and email attachments fighting for the same bandwidth.
2) It depends on your rate of archive log generation, the size of your archive logs, and your tolerance for how stale your standby can be. You need to look at your average and maximum archive log generation and figure out whether you can move the archive logs over the wire fast enough to satisfy your staleness tolerance.

Bandwidth for remote Lion Profile Manager server

Hi all,
Can anyone shed some light on what kind of upstream bandwidth you'd need to have for a remote Lion Profile Manager server to manage your Macs? I'm not thinking about accessing home directories over the Internet, just the configuration profiles.
Thanks in advance for any input,
Chris

Hi
64kbps for sites with approx 3-5 users or using ADSL lines with 512kbps

Remote Panel bandwidth

I am attempting to use the remote panel to connect over the Internet - the server VI is fairly intensive in terms of the controls/indicators etc., so that there is a bit of a draw on the available network bandwidth when I access it.
Is there a way to set the refresh or update rate for the the remote panel (either the client or the server), so that I query the remote panel at a slower rate (or update on demand)?
Or, would using data sockets on selected controls/indicators be a more efficient way of minimizing the bandwidth (this means I have to create a duplicate app on the client PC that subscribes to the selected controls, I imagine).
Thanks.

Another solution is to not try to transfer the screen image back and forth but just the data that's significant. I have done this in the past and it works well. A major advantage to this approach is that you get to control what data gets passed and how often it's transfered. For example, you could only send data that changes.
To implement this approach you will need to define a communications protocol. It could be built on the LV TCP/IP routines, Telnet, datasockets, remote VI server calls or any of several methods. It all depends on what features you need--and how much time you want to take.
If you have specific questions about this sort of technique I would be glad to answer them.

Remote Agent Bandwidth requirement & UCCX on the cloud

Hi,
There are Remote Agents working from home:(UCCX 9 & CUCM 9.1)
- Can they use jabber ?
- How much bandwidth do they need? for Call-signaling, just to log in and receiving the Call? I knoe in UCCX 7 it requires 16Kbps
- How recording works for those users?
If I want to put the UCCX on the cloud ( with all UC solution), how much bandwidth do I need and how the recording works?
Thanks,
Hamed

The amount of bandwidth required will be a function of two details. 1) what is the timeframe that the change takes place over? ie. does the 1gb change happen in 1 hr, 1 day, or 1 week? and 2) Since this remote mirroring will be async, how much delta between the databases are you willing to allow? ie. can the remote be 1 min out of sync, 10 min out of sync, or more? Since most db work is bursty, if we are given longer periods to sync the data, we can use a lower bw link.
These two questions need to be thought about and answered before a good answer can be given. You need to balance the cost of lost data vs. the cost of higher throughput circuits.

Hi Thomas,
You can use "Interface Graphs" in Pix Device Manager. This is a monitoring tool that will serve the purpose that you mentioned.

Creative Cloud Files – Syncing issues/Bandwidth hogging – Does it ever work?

Having been a Dropbox user for several years I was keen to start using the 100gb of Creative Cloud storage to enable me to work on a project from home and pick up where I left off in the office.
However it simply doesn't work properly!
For example:
I worked from home on Monday and Tuesday on a project. All the files were successfully uploaded from my home Mac within seconds/minutes. I came into work on Wednesday and the files had not appeared in my CC Files folder. I rebooted my Mac and paused and restarted the sync and left it running, a couple of the files appeared but the process seems to hang fairly quickly. I've left it running overnight and my files have still not synced! the status bar at the bottom of the CC app shows "Syncing file 7 of 181 (9hr left)" but it never gets any further.
When syncing is switched on and running the process kills all the bandwidth of my work Mac causing outgoing emails to spend up to an hour in my outgoing mail queue, slowing web browsing to a crawl, hampering any other web usage/downloads/streaming/remote access etc. To prevent this I changed the preferences to only allow CC 50% of the available upload and download bandwidth.
I have repeatedly logged out/rebooted my Mac, closed and relaunched the CC app, paused and restarted the sync process and run the
rm ~/Library/Application\ Support/Adobe/CoreSync/options.tix
command in Terminal as suggested in another thread.
The files I am syncing are not even that large, in total I am only using around 3% of my storage.
Am I on my own in experiencing these issues? Or are other people suffering too?

Hi Matt,
In order for us to take a deeper look at what's happening here, we would need to take a look at the log files on both your machines. The location of the coresync.log file is included below.
Could you also tell me what version of the Creative Cloud Desktop app you're using (from preferences) and the spec of the Macs?
Log file location:
Mac - /Library/Application Support/Adobe/CoreSync/CoreSync-yyyy-mm-dd.log
(On Mac, you need to use the Go To Folder option from the Go option in Finder (menu at the top). Then in the pop up enter:
/users/username/Library/Application Support/Adobe/CoreSync/
Then select go, this will take you to the folder containing the .log files.)
Please email this to me directly on [email protected]

SMTP chewing up bandwidth like crazy! Please help!

I've got a crazy problem with a client's server. First, it's an xServe running 10.4.11 with all software updates. It's been in service as a WWW, Mail, FileMaker, FTP, AFP & Windows file server for several years now. Up until the other day, the machine ran without too many glitches.
The other day, users started complaining that the Internet was really slow. After looking into it, I was able to conclude that SMTP was bogging down the connection. With SMTP off, repeated speed test resulted in about 6 Mbps consistently. When SMTP was fired back up, our speed test results would drop to 300 Kbps or less!!! If my math is correct, that means that SMTP alone was using more than 95% of our 6 Mbps of bandwidth!!!
I found that if I stopped Mail service using Server Admin -- or if I issue "sudo killall smtp", the connection speed would go back up. Then over the course of an hour or so, enough SMTP daemons launch and eventually bog down the connection again.
SMTP relay is OFF and I've confirmed that the server cannot be used as a relay. I've also confirmed it's not another machine on the network -- I literally unplugged the rest of the network so it was just me, my server, my router and my cable modem.
I booted the server from my service drive and examined the hard disks with Disk Utility and then DiskWarrior. I found and repaired only a couple of very minor problems. I also ran repair permissions on the boot volume. I have tried turning off mail service and creating a new, fresh IMAP database and mail store just to eliminate those as a cause. I tried removing the blacklist servers from the config, but that had no effect either.
When I look at the logs, nothing jumps out at me. Maybe because I'm not accustomed to looking at mail logs. Again, this problem is "all-of-the-sudden". Over the past several years, I would regularly connect to this server over the Internet for screen control with Remote Desktop and would get reasonably smooth performance. Now, SMTP has the Internet connection so jammed that I can barely connect with Remote Desktop (unless I kill off the SMTP processes first).
Below, I've included the postfix config files (/etc/postfix/main.cf & /etc/postfix/master.cf) AND the last 50 entries in the mail.log file. Hopefully I've answered most questions and made it clear that this problem is extreme and all-of-the-sudden. NOTE: I've changed my client's domain to 'mydomain.com' to protect their privacy -- But i've altered no other information.
Any suggestions??? I am at a total loss! If I install Mac OS X server, I create a lot of work for myself and the only reason I'm thinking of reinstalling is because I DON'T KNOW WHAT ELSE TO DO!!!

Further investigation shows that after killing all the smtp (or otherwise restarting it) it works fine for a while then goes nuts launching SMTP and SMTPD processes.
So if the connection is bogged down and SMTP is out of control, I issue:
sudo killall "smtp"
and the connection speed goes back to normal for a while and the output of
ps -aux | grep "smtp"
is as follows:
[server:~] admin% ps -aux | grep "smtp"

Bandwidth Utilization Avg or Max for capacity Planning best practice

Hello All - This is a conceptual or Non-Cisco product question. Hope you can help me to get this best industry practice
I am doing a Capacity planning for the WAN Link Bandwidth. To study the last month bandwidth utilization in the MRTG graph, i am seeing two values
Average
Maximum.
To measure how much bandwidth my remote location is using which value i have to use. Average or Max?
Average is always low eg. 20% to 30%
Maximum is continuous 100% for 3 hour in 3 different intervals in a day and become 60% in rest of the day
What is the best practice followed in the networking industry to derive the upgrade size of the bandwidth by using the Utilization graph
regards,
SAIRAM

Hello.
It makes no sense to use average during whole day (or a month), as you do the capacity management to avoid business impact due to link utilization; and average does not help you to catch is the end-users experience any performance issues.
Typically your capacity management algorithm/thresholds are dependent on traffic patterns. As theses are really different cases if you run SAP+VoIP vs. youtube+Outlook. If you have any business critical traffic, you need to deploy QoS (unless you are allowed to increase link bandwidth infinitely).
So, I would recommend to use 95-percentile of maximum values on 5-15 minutes interval (your algorithm/thresholds will be really sensitive to pooling interval, so choose it carefully). After to collect baseline (for a month or so) - go and ask users about their experience and try to correlate poor experience with traffic bursts. This would help you to define thresholds for link upgrade triggers.
PS: proactive capacity management includes link planning for new sites and their impact on existing links (in HQ and other spoke).
PS2: also I would recommend to separately track utilization during business hours (business traffic) and non-business (service or backup traffic).

Cisco SRP 527W Restricting Bandwidth on one SSID

Hi, We have a Cisco SRP 527W. I have set up two SSID's one for our office use and one for our customers to check emails and surf the net. At the moment we are finding that some customers are streaming content and using too much bandwidth, using too much bandwidth. I have set up the second SSID as a guest, though cant work out how to limit bandwidth or if this is possible. I can find my way around settings and follow instructuctions - though do not have a strong grasp on the terminology/jargon thus would greatly appreciate any instructions/advice and if relevant referrerals to paid support contractors who can help me implement (remotely) if too difficult. Thanks very much!

Thanks for the reply Paolo , unfortunately I do not have access to the U model of that router to test with , however I can provide details from the router that is operating sucessfully on the line at present as well as posting information from the dsldiag page when we go back out and retest.
The line settings that are sucessfully in use at present with the other vendors router are as follows:
VC MUX Encapsulation
VPi 0
VCI 38
Protocol PPPoA
ADSL2+ G.992.5
SNR Margin 9
Loop Attenuation 17
Many Thanks

P2P multicast and upstream bandwidth

Hi,
I'm in the process of developing a realtime video chat application where multiple users can send video streams simultanuously. The number of users receiving the streams can be very big, e.g. 10 broadcasters and 500 receivers, each receiver should get all streams.
I use RTMFP connections to an FMS and streams are published in P2P multicast groups by passing the groupspec to the NetStream constructor. Currently I'm having problems with audio/video synchronization and video stream 'jumps' (not continuous). From what I read on other threads, this is related to the fact that there is not enough upstream bandwidth for sending the streams. So my questions are:
How to calculate the required upstream bandwidth on every peer for the given example of 10 broadcasters and 500 receivers (is it 10*bandwidth of one stream)?
What settings (on NetStream, Camera, Microphone etc.) should be used for best results and how to adapt them based on the number of broadcasters?
I hope my questions make sense!
Thanks,
Haykel

I have done some tests to find out how much upstream bandwidth is used for different situations. The data is taken from the 'multicastInfo' property of all involved 'NetStream' objects as follows:
Multicast Data: average of 'multicastInfo.sendDataBytesPerSecond' of all streams.
Multicast Control : average of 'multicastInfo.sendControlBytesPerSecond' of all streams.
Different measurements have been done for different situations:
The user is broadcasting and not broadcasting
Varying number of connected users
Varying number of users broadcasting
I have limited the maximum video bandwidth to 16 KBytes with 'Camera.setQuality(1024 * 16, 0)'.
The application uses only application level multicast (passing a groupspec to the NetStream constructor). In this test all peers are on the same LAN and the FMS server is on a remote machine.
The results in Bytes/s (click to enlarge):
What I have noticed is that the outgoing multicast data volume grows by ~15 KByte with every new connected user (receiver) and goes down when the number of broadcasters grows. Is that normal? Does it mean that only the broadcasters are sharing the streams with the other peers? I thought that every peer would share the data with a number of neighbours (i.e. 3) which would share with their neighbours and so on.
During the tests I have also checked for a/v delays and noticed the following:
For every new stream, at the beginning audio and video are in sync but have a delay of ~3 seconds
After ~20 seconds the video delay becomes marginal but the audio remains delayed and so goes out of sync with video
After ~30 seconds the audio delay becomes marginal and goes in sync with video (a/v are now stable)
The delays of 20 and 30 seconds grow up to more than a minute when the number of broadcasters grows
My questions:
Are my measurements correct?
Why is the outgoing multicast data volume growing with every new receiver? Is the publishing stream sending the data to all peers?
Should I expect the bandwidth to grow indefinitly with the number of receivers or will it stabilize at some value?
How to decrease the time required for a/v to become stable (in-sync with a small delay)?
Is P2P multicast a good choice for this kind of applications (up to 10 broadcasters and a very big number of receivers)?
Any advices???
Thanks.

Bandwidth Error

Hello. My friend and I are trying to connect with each other via the iChat video chat but there seems to be an error. On her computer it says there is a bandwidth error but she can connect to everyone else but me. On my computer it says she has timed out. Here is the error screen. Someone please help.
2009-07-23 23:31:44 -0400: No data has been received for the last 10 seconds.
Audio channel info: local machine using 192.168.2.104:16402, expecting remote machine to send to 69.40.146.247:33779
Video channel info: local machine using 192.168.2.104:16402, expecting remote machine to send to 69.40.146.247:33779

Hi
First have you both set the Quicktime streaming setting, goto sys prefs/quicktime/streaming/streaming speed, set to 1.5mbps
In ichats prefs click on video and change bandwidth limit to 500.
Restart iChat.

Why is there no updates to the firefox throttle add-ons ? Is there an alternative? throttle is Bandwidth utilization throttling and monitoring extension for Firefox

Why is there no updates to the firefox throttle add-ons ? Is there an alternative? throttle is Bandwidth utilization throttling and monitoring extension for Firefox

Well, it's probably one of two things: either the awesome dude(tte) who developed this awesome extension was tired of updating or the changes in FFox software architecture carried out between version 3.x and 4+ created challenges that were too difficult for him to surmount or a combination of both. Honestly, I love Mozilla but I think they dropped the ball on the throttle issue. It's such an obvious and necessary function and it's so easy to implement. They should have included it a long time ago as in built feature. And, if you are browsing and looking at this post and you agree. Add a suggestion in mozilla.org. The more of us asking for this function, the better.
Meanwhile, I have the following solution for you:
Solution 0.6.9.23.11 (DIY Version of my Solution ):
Setting Up a Separate Portable Firefox 3.6.x that runs independently of and simultaneously to your latest version of Firefox
Get FireFox Portable 3.6.24:
http://portableapps.com/apps/internet/firefox_portable/localization#legacy36
It's a portable app, meaning that it's got all it's profiles and preference and application files in the same directory. It won't compete with your current installation of Firefox, has it's own separate extension folder etc...
Get Firefox Throttle 1.1.6
http://firefox-throttle.en.softonic.com/ (I couldn't find it in the official mozilla site)
It will be flagged as incompatible with even that old version of firefox (but it isn't). You just need to turn off compatibility checking. You can do that with this extension:
https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/?src=search
If you have Bookmarks you want to port to the portable (bad pun intend), backup them up to bookmarks.json file on your desktop and import them to the portable version. You can export/import more stuff using FEBE addon but that's a whole world of headaches if you don't your doing.
Many of your extensions favourites extensions will no longer work on FFox 3.6.x but if, in that same addon's page, you look around until you find a link to previous versions of the addon, you will notice that the compatibility info is right below the version numbers. Just download and install the latest version that is compatible with you 3.6.x....
Voila mon ami! Your FFox 3.6 portable has just become your own private Download Mule whom you can throttle to your hearts content (ever throttle a real Mule??? I wouldn't try it, personally...) Do your regular browsing in another (unthrottled) browser and do your big downloads in the Mule...
If you want to keep using your brand spanking new Firefox for other types of browsing while using this portable Mule edition for the downloads, just add -p -no-remote to the shortcut leading to your Firefox Portable Mule edition.
For example, my taskbar shortcut to my Firefox Portable is:
""C:\Program Files (x86)\FirefoxPortableLegacy36\FirefoxPortable.exe"
I just changed it to:
"C:\Program Files (x86)\FirefoxPortableLegacy36\FirefoxPortable.exe" -p -no-remote
This will make it occupy it's own independent instance and I can use the both my Firefox Nightly and the Firefox Portable editions at the same time (each one, using a different profile ie. extensions, cookies, password, cache etc).
If you're on Linux, you can just run this on Wine and set the Windows Version to Windows 2000 in the Wine config,

Solution 0.6.9.23.11 (Non-DIY Version of my Solution):
Download my preconfigured but SWAGGED-THE-HECK-UP PortableFirefox 3.6
Having realized that some of you may find the above to be daunting. I took my own customize firefox portable, took out all my data and compressed the folder (it's portable, so it'll run as soon as you unzip it).
Here is a screenshot:
http://www.mediafire.com/?o95nkwo8y6q535j
Here is the download link:
http://www.mediafire.com/?xdw87ivf3184u2s
Don't forget to modify your Start/Taskbar shortcuts:
"C:\wherever you decide to put it\FirefoxPortableLegacy36-Swagged-UP!\FirefoxPortable.exe"
I just changed it to:
"C:\wherever you decide to put it\FirefoxPortableLegacy36-Swagged-UP!\FirefoxPortable.exe" -p -no-remote
