Ways of Distributing Objects

• Message Passing

  • Object knows about network, Network data = Min needed.

• Argument/Return Passing

  • Like RPC, Network data = Size(Args) + Size(Return) + Size(Name).

• Serializing & Sending Object

  • Actual object including code is sent. Might need synchronization. Network data = Size(object code) + Size(object state) + Size(synchronization)

• Shared Memory

  • Rely on DSM implementation. Network data = Size(data touched) + Size(synchronization).
