If you are connecting terminals to your UTM application via direct connections as well as via multiplex connections of the Session Manager, the messages are distributed as follows:
Figure 16: Combination of multiplex and direct connections
This means that messages via direct connections can overtake messages via multiplex connections. In particular load situations, this leads to shorter response times on the direct connection if a data jam occurs on the multiplex connections. There can be several reasons for this:
The volume of messages from the terminals is so high that the multiplex connections are overloaded.
All UTM processes are occupied with jobs and therefore cannot retrieve all incoming messages immediately.
There are two ways in which the UTM administrator can avoid the probability of a data jam:
Increase the number of multiplex connections and distribute the volume of messages evenly over these lines.
Increase the current number of UTM processes.
To guarantee the administrator the fastest possible access to the UTM application at all times, the administrator’s terminal should be connected to the application via a direct connection.
