Bandwidth Provisioning
WebView Server Bandwidth
WebView bandwidth becomes a factor only in large reporting deployments where the WebView servers 
are not co-resident with the Distributor AW.
If WebView is deployed on separate servers, some configurations support up to four WebView Servers 
per Distributor AW with an HDS. For more specific information on the number of supported WebView 
servers, refer to the Hardware & System Software Specification (Bill of Materials) for Cisco ICM/IPCC 
Enterprise & Hosted Editions
, available at 
http://www.cisco.com/en/US/products/sw/custcosw/ps1844/prod_technical_reference_list.html
The factor that affects the bandwidth between the Distributor AW and a WebView server is the total 
amount of reporting users that connect to the WebView server(s). Test results indicate that 50 reporting 
users require approximately 314,573 bytes per second. A reporting user is defined as someone running:
  •
Two real-time reports refreshing every 20 seconds, with each report returning 50 or fewer rows. This 
is equivalent to running a monitoring script.
  •
One historical report per hour
  –
Half-hour historical reports are run for an 8-hour period
  –
Daily historical reports run for a 40-hour period
Unified CCE provides a bandwidth calculator that aids in determining the bandwidth requirements for 
the WebView server. This calculator is available at 
http://www.cisco.com/en/US/products/sw/custcosw/ps1844/prod_technical_reference_list.html
Reports Bandwidth
The factors that affect the bandwidth between the WebView server and WebView clients are the number 
of reporting users and whether Secure Socket Layer (SSL) is set to full-encryption mode. Test results 
indicate that for every 50 reporting users, bandwidth consumption is approximately 524,288 bytes per 
second, and full SSL encryption adds approximately 2,097 bytes per second.

Bandwidth Requirements for Cisco E-Mail Manager
Cisco E-Mail Manager communicates with a distributor AW for the following purposes:
  •
Authenticating agents
  •
Fetching configuration information from Unified ICM
  •
Uploading configuration information when a new agent or skill group is created in Cisco E-Mail 
Manager
  •
Synchronizing the configuration between the Unified ICM AW database and the Cisco E-Mail 
Manager database
Due to the high bandwidth requirements between these two components, Cisco recommends that they be 
deployed on the same LAN segment.
