The most expensive operation from a network perspective is the agent or supervisor login. This operation involves the web page load and includes the CTI login and the display of the initial agent state. After the desktop web page loads, the required bandwidth is significantly less.
Because Cisco Finesse is a web application, caching can significantly impact the required bandwidth. For example, the first time an agent logs in, the number of bytes transmitted is approximately 2 megabytes. If caching is enabled in the browser, during subsequent logins, the number of bytes transmitted is 138 kilobytes.
Because of the additional gadgets on the supervisor desktop (Team Performance, Queue Statistics), this number is higher for a supervisor login – approximately 2.5 megabytes without caching and 333 kilobytes with caching. To minimize the amount of bandwidth required for login, make sure that caching is enabled in the browser.
Cisco does not mandate
a minimum bandwidth for the login operations. You must determine how long you want the login to take and determine the required bandwidth accordingly. To help you with this calculation, Cisco Finesse provides a bandwidth calculator (at http://www.cisco.com/c/en/us/support/customer-collaboration/finesse/products-technical-reference-list.html) to estimate the bandwidth required to accommodate the client login time.
Note that during failover, agents are redirected to the alternate Finesse server and required to log in again. For example, if you configure your bandwidth so that login takes 5 minutes and a client failover event occurs, agents will take 5 minutes to successfully log in to the alternate
After login is complete, the most intensive operation for both an agent and a supervisor is making an outbound call to a route point. For the supervisor, updates to the Team Performance and Queue Statistics gadgets may be occurring concurrently. You can use the Cisco Finesse bandwidth calculator to calculate the total bandwidth required for connections between all Finesse clients and the Finesse server.
The Cisco Finesse bandwidth calculator does not include the bandwidth required for any third-party gadgets in the Finesse container or any other applications running on the agent desktop client.
Other applications at the remote client location may compete for total bandwidth to that remote client.
The bandwidth listed in the bandwidth calculator must be available for Finesse after you account for the bandwidth used by other applications, including voice traffic that may share this bandwidth. The performance of the Finesse interface, and potentially the quality of voice sharing this
bandwidth, may degrade if sufficient bandwidth is not continuously available.
