Cisco Cisco IPCC Web Option Design Guide

Calculating bandwidth requirements for servers that have only one network interface card (NIC) requires 
adding the totals for each link entering the system. For example, for a standard reporting deployment 
with an Administrative Workstation (AW), an Historical Data Server (HDS), and one NIC, you would 
calculate the required bandwidth as follows:

Total bandwidth for reporting = Report data bandwidth + Reports bandwidth

However, for a large reporting deployment, the bandwidth is calculated as follows:

Total bandwidth for reporting = Report data bandwidth + WebView sever bandwidth

Due to the nature of the recovery process, it is possible to experience a period of network slowdown 
during periods of recovery.

The following sections describe the calculations necessary to determine bandwidth requirements for 
each network path shown in 

 and 

.

The factors that affect the bandwidth between the Central Controller and a Distributor AW with an HDS 
are calls per second (cps), the number of agents, and the use of Extended Call Context (ECC) variables. 
Test result indicate the following general guidelines:

For every 10 cps, bandwidth consumption is about 42,000 bytes per second.

10 agents require approximately 12,000 bytes per second.

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

Unified CCE provides a bandwidth calculator that aids in determining the bandwidth requirements for 
report data. This calculator is available at
