  2. Outline • Remote Object Invocation • Message Oriented Communication • Stream-Oriented Communications

  3. Distributed Objects like client stub like server stub • Common organization of a remote object with client-side proxy. 2-16

  4. Parameter Passing • The situation when passing an object by reference or by value • Copy local object • Send only reference to remote object 2-18

  5. Outline • Remote Object Invocation • Message Oriented Communication • Stream-Oriented Communications

  6. Persistence and Synchronicity in Communication (1) • General organization of a communication system in which hosts are connected through a network 2-20

  7. Persistence and Synchronicity in Communication (2) • Persistence • Message is stored in the network or at the receiving machine as long as it takes to be delivered • E.g., mail system • Synchronicity • Sender blocks until the receiver gets the message

  8. Persistence and Synchronicity in Communication (3) • Persistent communication of letters back in the days of the Pony Express.

  9. Persistence and Synchronicity in Communication (4) • Persistent asynchronous communication • Persistent synchronous communication 2-22.1

  10. Persistence and Synchronicity in Communication (5) • Transient asynchronous communication • Receipt-based transient synchronous communication 2-22.2

  11. Persistence and Synchronicity in Communication (6) • Delivery-based transient synchronous communication at message delivery • Response-based transient synchronous communication

  12. Outline • Remote Object Invocation • Message-Oriented Communication • Message-Oriented Transient Communication • Message-Oriented Persistent Communication • Stream-Oriented Communications

  13. Berkeley Sockets (1) • Socket primitives for TCP/IP.

  14. Berkeley Sockets (2) • Connection-oriented communication pattern using sockets.

  15. The Message-Passing Interface (MPI) • Some of the most intuitive message-passing primitives of MPI.

  16. Outline • Remote Object Invocation • Message-Oriented Communication • Message-Oriented Transient Communication • Message-Oriented Persistent Communication • Stream-Oriented Communications

  17. Message-Queuing Model (1) • Four combinations for loosely-coupled communications using queues. 2-26

  18. Message-Queuing Model (2) • Basic interface to a queue in a message-queuing system.

  19. General Architecture of a Message-Queuing System (1) • The relationship between queue-level addressing and network-level addressing.

  20. General Architecture of a Message-Queuing System (2) • The general organization of a message-queuing system with routers. 2-29

  21. Message Brokers • The general organization of a message broker in a message-queuing system. 2-30

  22. Outline • Remote Object Invocation • Message-Oriented Communication • Stream-Oriented Communications

  23. Data Stream (1) • Setting up a stream between two processes across a network.

  24. Data Stream (2) • Setting up a stream directly between two devices. 2-35.2

  25. Data Stream (3) • An example of multicasting a stream to several receivers.

  26. Specifying QoS (1) • A flow specification.

  27. Specifying QoS (2) • The principle of a token bucket algorithm.

  28. Setting Up a Stream • The basic organization of RSVP for resource reservation in a distributed system.

  29. Synchronization Mechanisms (1) • The principle of explicit synchronization on the application level data units.

  30. Synchronization Mechanisms (2) • The principle of synchronization as supported by high-level interfaces. 2-41
