• When a new platform front-end starts it creates an internal RMI registry on the current host, as well as the ACC, AMS, and DF.
• When a new container starts it looks up the RMI registry and gets the platform front-end object reference.
• When an agent sends a message, three things are possible.
  1. If receiver is on same container then pass ACL message using event object.
  2. If receiver is on same platform but different container then ACL message is sent using RMI.
  3. If receiver is on different platform then IIOP protocol is used, as per FIPA standard. The ACL message is transformed into a character string and the remote invocation is done using IIOP.
