Connections are established in several steps. First, an attempt is made to connect to the cp which has been specified in the configurationA set of constituent components that make up a system.

If it is possible to establish a connection, the cp sends performance values regarding this connection and all cp addresses known in the system to the client (UserInterface or agent). The cp addresses serve to update the corresponding section in the configuration file. The client connects to all these processes and obtains their performance values in order to identify the cp with the most optimal values i.e. the lowest work load. This communication process is then used to start job processing as required. The connections to all other communication processes are terminated.
A AE system can have up to 12288 active agent connections and 1024 active user connections.
