Bandwidth Provisioning
Bandwidth and Latency Requirements for the User List Tool
In deployments in which a client AW is remote (connected over a WAN) from the domain controller and
distributor AW, specific network bandwidths and latencies are required to achieve reasonable
performance in the User List Tool. Reasonable performance is defined as less than 30 seconds to retrieve
users. This information is provided in an effort to set expectations and to encourage upgrading to Cisco
Unified CCE and ICM 7.2(3) or later releases. In this version, changes were made to enhance the
performance of the tool under these conditions.

There are a number of other things that can be done to improve performance of the User List Tool.
Moving a distributor AW and a domain controller local to the client AW can greatly enhance
performance, as shown by the LAN row in

will improve performance, and increasing the bandwidth of your WAN connection will also improve
performance.
performance.
The following data points describe scenarios in which the User List Tool can retrieve users within
30 seconds in Unified CCE 7.2(3) or later releases. If you are using an earlier version of Unified CCE
and are experiencing significantly slower retrieval times, consider upgrading to Unified CCE 7.2(3) or
later releases. Additionally, laboratory testing has determined that the tool cannot perform reasonably
for any number of users on networks with a one-way latency greater than 50 ms.
