Video Bandwidth Calculation

[jesusdavidzambrano]

Hi,

I have 33 sites with video, but, I dont know if is necesary aditional bandwith depending of the layout on the screens. Aditional I need to know how to calc the bandwith to datacenter MPLS channel in where is allocated the Meeting Server.

1 Site SX20

32 Sites SX10

Bandwith per site 1472 kbps to a 1080p30 video.

Datacenter Bandwith: ?

Thanks for any help!

Hi,

You can reference the White paper  "Tested Bandwidth Usage for Cisco TelePresence Endpoints in a Point-to-Point Call" 

http://www.cisco.com/c/dam/en/us/products/collateral/collaboration-endpoints/tested_bandwidth_whitepaperx.pdf

and the Bandwidth section of the Collaboration SRND

http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/srnd/collab11/collab11/cac.html

"Table 13-3 Cisco TelePresence Endpoints – Example Bandwidth Usage" and "Table 13-9 Example of Group Region Matrix" of the above link can be used as a reference.

Every call will consume a portion of the total bandwidth at each site.

For example, using a call rate of 1152kbps:

• One remote site with 1 endpoint calls into the Meeting Server will consume 1152kbps at both the remote site and data center.
• One remote site with 2 endpoints call into the Meeting Server will consume 2304kbps at both the remote site and data center.
• Two remote sites with 1 endpoint each call into the Meeting Server will consume 1152kbps at each remote site, and 2304kbps at the data center.
• Two remote sites with 2 endpoints each call into the Meeting Server will consume 2304kbps at each remote site, and 4608kbps at the data center.
