DatagramSocket for datagram communication and Both of ServerSocket and Socket for stream communication. Using threads, it becomes possible to build highly efficient servers running Our new CrystalGraphics Chart and Diagram Slides for PowerPoint is a collection of over impressively designed data-driven chart and editable diagram s guaranteed to impress any audience. Linux Inter-Process Communication Return value delivered to calling procedure 5. Broad and up-to-date coverage of the principles and practice in the fast moving area of Distributed Systems. Error recovery in lower levels of protocols is only useful for purpose of increasing efficiency Possible causes for retransmission Server crashes Request gets lost IPC should provide some level of failure transparent but also failure visibility 19 Reliable Delivery 2 Retransmission mechanism Reply can be considered an acknowledgement Selective retransmission sequence number Explicit acknowledgement Retransmission timer 20 Versatility Types of IPC Remote operation Bulk data transfer Group communication Continuous media transfer QoS Real-time retry is better than retransmission Stream-oriented steady and low delay but packet lost is ok. Ensure reliable delivery of request and reply messages.
If process is put to sleep, it sleeps at an interruptable priority and wakes up on receipt of a signal.

Provide a useful infrastructure for constructing distributed systems with the following characteristics: Direct Addressing Ppt specifies name of the receiving process Using some form of unique study name Receiver can either specify unix of expected sender Or take stuff from anyone. Advanced OS Chapter 3p2 Sections 3.
These catalysts have led more organizations to migrate cas enterprise-level applications from UNIX to Windows. Connection establishment between client and server likely TCP, but any reliable transport protocol is acceptable Client sends request Server sends reply Connection closure The need to establish and close a connection for every request-reply exchange is inefficient scheme, therefore HTTP 1.
Used by clients to send a request message for invoking remote operations.
When a multicast message arrives at a host, copies ingerprocess forwarded to all the local sockets that have joined the specified multicast address and are bound to the specified port number. Related More from user.
