Bandwidth requirement for Storage over WAN

Working on a project for storing data across geographically dispersed locations, I need to be able to estimate how much bandwidth that will be required to do remote mirroring. I assume the initial data has been loaded on my backup servers at the 2 locations but I need to have a fair idea of how much bandwidth remote mirroring will translate to for approx 1Gb change in my main site server data.
Could anyone please help out.

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.

Bandwidth required for Peoplesoft

Hi,
We are doing sizing in terms of the bandwidth required for peoplesoft v9.0. The server is going to be based in a central location. It is my understanding that Self service and GP would be the most bandwidth consuming modules. GPl would be run from a central location and all employees who will be spread over different geographical locations would have access to Self Service. Do you have any idea of what the minimum bandwidth required would be in this case? I understand that Peoplesoft is PIA but there will be some minimum bandwidth requirement for good performance. I would appreciate any input in this regard, even rough estimates or past experiences will be really helpful. Thanks

I don't have any solid tcp/ip numbers for you. Most of the network traffic is between the web, app, and database servers. If your users can browse the web (MSN, Google, etc) from their location without complaints, they will be able to use PeopleSoft. If you turn on gzip compression in your web profile, that will help a lot. Most of the PeopleSoft JavaScript, CSS, and images are stored as external files so they benefit from client side browser cache. Once a user loads a page, all that will travel back and forth is the HTML that comprises the page itself. Yes, the HTML is a bit bloated as it is based on the HTML design model from several years ago (lots of tables for formatting). A FieldChange, button click, or save will reload the entire page.
Are your users going to be using 56k modems or something better? Really, latency is probably more important than bandwidth in this case.
PeopleSoft doesn't maintain a persistent connection between the web server and browser, so I'm not sure that distance is really an issue.
Just to give you some rough numbers, with JavaScripts, etc in my browser cache, the contents of the Timesheet page is 39k without gzip compression and 6k with gzip compression. So, with gzip compression turned on, you should get much better use of your bandwidth.

Bandwidth requirement for voice calls

Hi All,
Need expertise advise on the following concern about voice call.
1. Bandwidth requirement for video call across all other endpoint(using Polycom / Lifesize end point at their end)
a)Standard Video
b)1K HD Video
c)4K HD Video
2. Plus can we determine bandwidth required for all the following below:
a. 1 to 1 VC end point ( Cisco TP – Cisco TP)
b. Bridge call ( Cisco TP to Polycom / Lifesize)
c. 1 to 1 VC end point ( Cisco TP – Polycom / Lifesize)

Thanks for the info Wayne. I missed out information about the endpoint.
Client using CTS 3010. Acoording to datasheet it says
11.9 Mbps (1080p, 30 fps best motion handling), 10.1 Mbps (1080p, 30 fps better motion handling), 8.8 Mbps (1080p, 30 fps good motion handling)
6.4 Mbps (720p, 30 fps best motion handling), 4.5 Mbps (720p, 30 fps better motion handling), 3.1 Mbps (720p, 30 fps good motion handling)2
My question is does the bandwidth required for both ways or only one way?
And I'm aware CTS 3010 doesn't support 4K video.

Bandwidth required for Lync 2013 audio video call

Hi,
what is the required bandwidth required for lync 2013 audio video call from out side of company network. considering users will use owa integration with exchange 2013 for audio video call.
i tried with lync bandwidth calculator but could not figure it out.
actually i have some remote site where users have connectivity of 160 kbps only.

There are a number of variables such as call type and video resolution, but I would suggest using this table as a guide:
http://technet.microsoft.com/en-us/library/jj688118.aspx
For example for capacity purposes with a Lync peer-to-peer call you're looking at 57Kbps (86 with FEC)

Total Bandwidth requirement for 720p 30fps video call to mcu 5300 and P2P call

Hi All,
One of customer purchased 5300 MCU VCSC and VCSE from us.
All infra will be setup in their HQ and all endpoints are from internet. All endpoints will register to VCSE.
customer requirements are 5 concurrent encrypted calls to MCU with 720p 30fps and point to point 10 concurrent encrypted calls.
endpoints are cisco c series endpoints and polycom HDX endpoinds.
They haven't subscribe the line yet. we need to propose the minimum bandwidth requirement to customer.
1) what is the minimum bandwidth requirements to achieve 720p 30fps encrypted call to MCU?
2) what is the total bandwidth requirements for 5 concurrent encrypted calls to MCU?
3) what is the total load of bandwidth requirements for 5 concurrent encrypted calls to MCU and point to point 10 concurrent encrypted calls?
Thanks advance for you answer!

point to point 10 concurrent encrypted calls?
Even with a miltisite license installed on the codec to enable the built in bridge on the endpoint, you're only going to be able to connect up to 3 sites max, the endpoint hosting the conference that has the multisite option + 3 others. You'll have to rely on the MCU to host these conferences.

I can't get FaceTime to work. A 'Ping' check tells me that I've got 20Mb download and 1 Mb upload. Is this enough ? What are bandwidth requirements for FaceTime? If I've theoretically got a fast enough connection, then where is the restriction of bandwidth occurring?   How can I find out whether the problem is inside my computer, or on the net?

Bandwidth Requirement for VT advantage..

How much BW is required for a Video calls for g729 codec and g.711 calls.
Where to define the codec for video calls.
How to size the BW for calls over LAN as well as for WAN.

There is no g729 or g711 codec for video, it is wideband, h.263, etc. G729 and g711 are for audio calls only.
The VT Advantage video cameras support Wideband video codec, i.e., up to 8128 kbps, which if used is ofcourse recommended only with the same LAN, and H.263 video codec, i.e., from 128 kbps to 1.5 Mbps, over the WAN.
Codec for video calls are defined in System > Region but in terms of bandwidth (128kbps, 384kbps, etc in increments of 64kbps) and not the actual codec.
For connections over the WAN, 128 kbps is the minimum and considered low-quality video, and from 384kbps upwards considered high-quality video. However the actual bandwidth used on the WAN and the QoS configs would be the bit-rate + 20% overhead, which for a video call at 128 kbps would be 154 kbps and for a video call of 384kbps, would be 460 kbps. This bandwidth includes both video and audio channel of the video call.

Dynamic bandwidth selection for PPPoE over Ethernet/VLAN

Hello all, hope you are doing great.
I'm planning to deploy PPPoE Server (Cisco Router 7609) for a ISP. This ISP will provide Internet connection for customer over Ethernet.
I have to provide a solution to assign bandwidth to each customer by RADIUS and I find some clues that Dynamic Bandwidth Selection (DBS) should be the answer. Unfortunately, DBS only support PPPoA or PPPoE over ATM.
If you have any experience with equivalent function, please help me. Thank you very much.

Bandwidth requirement for a Mobile solution

Hi
Is there any data that I can use to determine the bandwidth requirement needs for a mobile solution? (In a connected mode). Lets assume that we have only 1 user using only one app/screen - mobile sales order. For each sales order, what will be the bandwidth used? Assumption is that the screen is also loaded and data is also transmitted.
Thanks in advance

Hello Robert,
please have a look at the SDN Mobile Infrastructure "homepage" and select the implementation case studies from the e-learning iview. Maybe there you can get an impression about possible implementation efforts.

Bandwidth Requirement for Video Call

Hi,
I am having Cisco 9951 phones in my all location now we want to configure Video call between two location (Head office to SRST locaiton). Please help me how much bandwidth is require to make video calls.
Also, what all configuration is require for the same.
Regards,
Shambhu

The default is inter-region max video call bit rate is 384K, close to one video call.
The default Interregion max video call bit rate is 384K.
The bandwidth would depend on the resolution being used. The recommended bandwidth for resolutions are as follow:
VGA 360p@30fps: 768 - 2000kbps
VGA 360p@15fps: 448 - 767kps
CIF@30fps: 320 - 447kbps
CIF@15fps: 256 - 319kbps
QCIF@30fps: 128kbps – 255kbps
QCIF@15fps: 64 - 127kbps
And 9971 IP Phone supports below formats:
SQCIF (128 x 96 pixels)
QCIF (176 x 144 pixels)
QVGA (320 x 240 pixels)
SIF (352 x 240 pixels)
CIF (352 x 288 pixels)
VGA (640 x 480 pixels)

How to reduce bandwidth required for spa9000 to spa941 link

Anyone can help me with this situation?
I have an spa400-spa9000-spa941 configuration over a satellite internet link. It works fine, during low traffic hours (night) but during the day the voice quality goes really bad (cutted voice, constant interruptions, etc).
We have already measured the bandwidth consumed by the spa941 to spa9000 link, and have found it at 80kbps upstream by 80 kbps downstream. We require to reduce it at least half of the actual values (40 kbps up by 40 kbps down).
We have already tried changing the codecs through the spa941 configuration menu: ( EXT1 –> Audio Configuration -> Preferred Codec -> G726-16 ), without success.
It seems that although we do that changes, the link between spa941 and spa9000 keeps working with the G711u codec.
We require that both calls coming in and out the spa9000 are compressed with a less bandwith consuming codec.
Which options do we need to change in the spa9000 and spa941 in order to make the G726-16 (or a less bandwidth consuming codec) the default codec between both equipments?
We are using firmware version 5.1.9 for spa9000 and version 5.1.8 for spa941.

I have the following options selected in SPA9000 SIP configuration:
SDP Payload Types
-->RTP-Start-Loopback Codec: G726-16
Internal Music Source Parameters
-->Internal Music LBR Codec: G726-16
-->Internal Music Preferred Codec: Low Bit Rate
Auto Attendant Parameters
-->AA LBR Codec: G726-16
-->AA Preferred Codec: Low Bit Rate
... and the following options selected in SPA941 EXT1 configuration:
Audio Configuration
-->Preferred Codec: G726-16
-->Use Pref Codec Only: Yes
With this configuration when we try to dial from SPA941 to remote SPA9000 we get BUSY tone.
Any other thing we should check?

Hosted dns-sd for bonjour over wan

Has anyone found a company that will host a dns domain that supports dns-sd registration..
I have installed the bonjour pref pane and would love to have someone manage a dns server that I can have a domain and register my services. For example, I would like to be able to access my airdisks at work and do so via bonjour and not use something like dyndns.org
I know how to work around this, but it would be nice to pay $20 a year for a domain or subdomain that supports bonjour wan service registration

As I mentioned above, dyndns is not the optimal solution. dnydns.org does not support dns service discovery.
http://www.dns-sd.org/
Normal link-local bonjour uses multicast dns to do service discovery. (eg. what airdisks are available on this network). Bonjour over the WAN relies on having a dns server configured with some apple extensions that let applications "register" their services with a central dns server that then keeps track of different service types. Usually this registration is controlled via simple authentication (username/password). Then, I would configure the bonjour pref pane (http://www.dns-sd.org/ClientSetup.html) to register my hosts services (itunes shared library, ichat bonjour, ssh server, web server, etc) in a specific domain. Then when another client that is configured correctly fires up an application that supports bonjour (like itunes) not only will it see itunes shares on the same subnet, but it should also see ones that are in bonjour dns-sd/wan domains that my host is configured to query.
You can only register services in one domain, but you can query multiple domains.
So, what I want is to have something like dyndns.org, but would let me use it to register my services (like my airport extreme connected printers and airdisk) so that when I am at work, I can use the airport disk utility menu bar item to mount my drives from home at work.

ARD or DS for deployment over WAN?

Hi, I was hoping to get some advice on best practice for a particular scenario, any input would be appreciated :-)
Scenario
We have two sites, site "A" and site "B".
We have a server at both site A and B.
Site A is our primary location - all clients / server reside on a LAN - management is very straight forward.
Site B however, is located over 40 minutes away and is accessible via a WAN.
I use a combination of tools for management at site A, including DeployStudio, ARD and OS X Server 10.9, however I now have to start managing both sites.
1) When using ARD at site A, is it possible to direct clients (at site B) to a local repository, rather than transferring huge packages over the WAN - which seems to be exceptionally unreliable?
2) Is there a more effective way of doing this, would DeployStudio or similar product be a better tool for this job?
Thanks

ARD itself does not have any repository at all not even for a single site. It works by you browsing for and pushing the package. As has been pointed out this does not work well for a multi-site situation.
For a multi-site situation your options would be to use -
Munki,
Simian,
Casper JDS
Simian can be considered an extension of Munki with more support for a geographically distributed setup.
Casper can have multiple JDS servers and the master can feed packages to additional JDS server with at least one being located at each site. I feel Casper would be the easiest to get running but unlike the others it is not free.
DeployStudio is something else entirely but it also has the ability to have a master server and slaves that sync to it.
