Discuss the tasks of encapsulation, concurrent processing, protection, name resolution, communication of parameters and results, and scheduling in the context of the UNIX file service distribuidls that of another kernel that is familiar to you. Distributed Objects and Components Distributed Objects and Components Introduction This essay will identify the differences between objects and components and what it means for a component to be distributed.

The computer network is A Network computer with cable B Network computer. Take into account all of the conditions causing a connection to be broken. Topics to be covered. Is there a need for asynchronous invocation if the client and server processes are threaded?

Today networks More information. Twisted pair, coaxial cable. The OSI model has seven layers. Networking layers More information. A service is implemented by several servers. Bandwidth Aggregation, Teaming and Bonding Bandwidth Aggregation, Teaming and Bonding The increased use of Internet sharing combined with graphically rich web sites and multimedia applications have created a virtually insatiable demand for Internet More information.

Event-based middleware services 3 Event-based middleware services The term event service has different definitions. Network Pop Quiz 5 Brought to you by www. Assuming a DSM system is implemented in middleware without any hardware support and in a platform-neutral manner, how would you deal with the problem of differing data representations on heterogeneous computers? In publish-subscribe systems, explain how channel-based approaches can trivially be implemented using a group communication service?


Now give an example showing how the client will invoke the pairin method, explaining how it will acquire the value returned via the second argument. XML elements can carry strings represented as base Would you expect process migration to have a significant cost?

Explain the advantage of copy-on-write region copying for UNIX, where a call to fork is typically followed by a call to exec.

Distributed Operative Systems

The value in the pair is supplied to the client via a second parameter. Introduce the concepts of internetworking More information. Is there a need for asynchronous RMI if processes are multi-threaded? Suggest a design for a notification mailbox service that is intended to store notifications on behalf of multiple subscribers, allowing subscribers to specify when they require notifications to be delivered.


Give examples of applications where the use of mobile code is beneficial. If no matching pair is available, an exception is thrown. Basic Networking Concepts 1. Is this the future of web based software development?

The client takes 5 milliseconds to compute the llvro for each request, and the server takes 10 milliseconds to process each request. Introduce the concepts of internetworking.

Is it a necessary condition for idempotence that the operation should not be associated with any state? Bandwidth Aggregation, Teaming and Bonding The increased use of Internet sharing combined with graphically rich web sites and multimedia applications have created a virtually insatiable demand for Internet. How would you implement the equivalent of a remote procedure call using a tuple space? Chapter 10 1 2 Statement Complexity Distributed systems consist of many interacting components.

Define an exception that can be thrown whenever any one of the operations cannot be carried out.

Consider a simple server that carries out client requests without accessing other servers. The service acquires events.

What is novel about cloud computing as a concept? What are the advantages and disadvantages of implementing a remote procedure call style interaction in this way? William Distribudos Data and Computer Communications.
