Chapter 11 Bandwidth Provisioning and QoS Considerations<br />

OL-8669-05<br />

However, for a large reporting deployment, the bandwidth is calculated as follows:<br />

Total bandwidth for reporting = Report data bandwidth + WebView sever bandwidth<br />

Bandwidth Provisioning<br />

Note Due to the nature of the recovery process, it is possible to experience a period of network slowdown<br />

during periods of recovery.<br />

Report Data Bandwidth<br />

WebView Server Bandwidth<br />

The following sections describe the calculations necessary to determine bandwidth requirements for<br />

each network path shown in Figure 11-6 and Figure 11-7.<br />

The factors that affect the bandwidth between the Central Controller and a Distributor AW with an HDS<br />

are calls per second (cps), the number of agents, and the use of Extended Call Context (ECC) variables.<br />

Test result indicate the following general guidelines:<br />

For every 10 cps, bandwidth consumption is about 42,000 bytes per second.<br />

10 agents require approximately 12,000 bytes per second.<br />

For each 1000 ECC bytes and 50 cps, the bandwidth consumption is 1,200,000 bytes per second.<br />

<strong>Unified</strong> CCE provides a bandwidth calculator that aids in determining the bandwidth requirements for<br />

report data. This calculator is available at<br />

WebView bandwidth becomes a factor only in large reporting deployments where the WebView servers<br />

are not co-resident with the Distributor AW.<br />

If WebView is deployed on separate servers, some configurations support up to four WebView Servers<br />

per Distributor AW with an HDS. For more specific information on the number of supported WebView<br />

servers, refer to the <strong>Cisco</strong> ICM/CCE & Hosted Editions Release 7.0(0) Hardware and System Software<br />

Specifications (Bill of Materials), available at<br />

http://www.cisco.com/univercd/cc/td/doc/product/icm/ccbubom/index.htm<br />

The factor that affects the bandwidth between the Distributor AW and a WebView server is the total<br />

amount of reporting users that connect to the WebView server(s). Test results indicate that 50 reporting<br />

users require approximately 314,573 bytes per second. A reporting user is defined as someone running:<br />

Two real-time reports refreshing every 20 seconds, with each report returning 50 or fewer rows. This<br />

is equivalent to running a monitoring script.<br />

One historical report per hour<br />

– Half-hour historical reports are run for an 8-hour period<br />

– Daily historical reports run for a 40-hour period<br />

the WebView server. This calculator is available at<br />
