Message Delivery
•
•
•
•
•
Communication between different Environments within the Simulation is
coordinated with a Message delivery system
Each Environment has an Inbox, an Outbox, and a MessageHandler
who knows how to sort/deliver Messages.
Messages include a delivery address and some Agent Information
(pointer, actual Agent object, or perhaps other descriptors )
Each Environment must take three actions per Step
– ReceiveAgents (Take Messages in Inbox and distribute to the
appropriate AgentLists)
– UpdateAgents (Update sub-Environments first, then update all
AgentLists)
– SendAgents (Take any Messages placed in the Outbox during the
Step and deliver it to the appropriate Inboxes)
Some Caveats
– The Simulation Object only has an Inbox as it does not generate any
of its own Messages to be delivered.
– SpaceEnvironments would need to know the address of neighboring
SpaceEnvironments
– Addressing convention must be assumed that can correctly route
the Messages to the right AgentList within the right Environment
