You can set a limit on the maximum number of concurrent connections that a user can have by counting the number of connections associated with a username. When user concurrency management is enabled, SBR Carrier servers in the cluster compare the number of active connections for a user to the user’s maximum limit each time a new connection is requested. If a new connection exceeds the limit, Session State Register may reject or allow the additional connection. In either case, the event is logged in the server log.
When counting connections, Session State Register does not distinguish between multi-link connections and new user authentication attempts.
