CASE STUDY INTERPROCESS COMMUNICATION IN UNIX PPT
Distributed Objects and Components: A request ID taken from an increasing sequence by the client process to make the identifier unique to the client. ObjectInputStream class is opened on a stream of data to deserialize an object from that stream using the readObject method. Signals Inform process of occurrence of asynchronous events. And, best of all, most of its cool features are free and easy to use.
Used by a server process to send the reply messages to clients Its arguments are the reply, and IP address and port of designated client. Cloud computing, network virtualization, operating unix virtualization, message ppt interface, unstructured peer-to-peer, communication spaces, loose coupling in relation to web services. Not all computers store primitive data values in the same order. Devoted to a major new case study on the Google study. Semantics of RPC Similar to regular procedure call 1. Making generic serialization and deserialization is possible using reflection rather than to generate special marshalling functions for each type of object as in CORBA.
To provide modularity by a well defined interface mechanism Concerned with the flattening and external data representation of any single object or tree of objects. Address of this routine is located in uarea next to signal number.
Acknowledgments are not required since requests are followed by replies.
