Chapter 12 Bandwidth Provisioning and QoS Considerations
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 Administration & Data Server, an Historical Data Server (HDS), and one NIC, you would
calculate the required bandwidth as follows:
adding the totals for each link entering the system. For example, for a standard reporting deployment
with an Administration & Data Server, 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
Note
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 Figure 12-12 and Figure 12-13.

Report Data Bandwidth
The factors that affect the bandwidth between the Central Controller and an Administration & Data
Server are calls per second (cps), the number of agents, and the use of Extended Call Context (ECC)
variables. Test results indicate the following general guidelines:
Server are calls per second (cps), the number of agents, and the use of Extended Call Context (ECC)
variables. Test results 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

WebView Server Bandwidth
WebView bandwidth becomes a factor only in large reporting deployments where the WebView servers
are not co-resident with the Administration & Data Server.
are not co-resident with the Administration & Data Server.
If WebView is deployed on separate servers, some configurations support up to four WebView Servers
per Administration & Data Server. For more specific information on the number of supported WebView
servers, refer to the Hardware & System Software Specification (Bill of Materials) for Cisco CCE

The factor that affects the bandwidth between the Administration & Data Server and a WebView server
is the total number of reporting users who 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:
