Need Help please!!

Oct 12 2006 6:43 PM
Hi,
 
I need help in understanding the following project. I am new in the world of programming so I need your help. I really wish if you could help me out.
Thank you very much.
 

 

Purpose:

This project requires you to develop the infrastructure for, and demonstrate, a remote execution facility.  This facility is based on message-passing communication and the use of application and library wrappers to support a very flexible system for connecting applications.

 

The purpose of this system is to support the building of applications from parts that may be distributed across processes, machines, or even networks, using message-passing communication based on sockets or web services.   Wrappers support the inclusion of legacy code that was not designed for this pluggable architecture.  Of course, new application parts can be designed to directly support the message-passing protocol you choose for this system, and would then need no wrapper.

 

The system you are required to implement is composed of a message-passing communication facility, that client's access through a communicator interface and object factory, local and remote executives that know how to spawn processes and load libraries, and wrappers that derive from a wrapper interface or abstract class [1] .  You are required to build a demonstration system that uses one existing application, one existing library, and an application or library you build specifically for this demonstration.   The demonstration entails supporting a user interface in one process and its applications and libraries in another process.   That process may reside on another machine.

 

Requirements:

Your RemExec program:

 

  1. shall compile, link, and execute using the Visual Studio.Net development environment.  You shall implement these programs using C# and the .Net framework class libraries.
  2. shall provide a Forms-based user interface, local and remote executives, wrapper class(es) and one new demonstration application (hello world is acceptable), that support the processing described below.
  3. shall establish communication [2] between a user's form and remote processing, based on XML message-passing [3].
  4. shall support the execution of code that resides in legacy applications and libraries via XML message-passing.
    1. shall support loading, execution of code in legacy libraries, and communication of results back to the user's form, via wrappers designed for this purpose.  
    2. shall support startup, execution of code in legacy applications, and communication of results back to the user's form, via wrappers designed for this purpose.  
  5. shall support file transfer between local and remote executives, as one means of communication between user's form and legacy code.
  6. shall demonstrate partitioning a new application across processes, using local and remote executives.

[1] You may wish to use an abstract class instead of an interface so that the class can provide message handling used by all derived classes.

[2] You may use .Net sockets, tcpClient and tcpServer classes, .Net Remoting, or .Net web services for this communication function.

[3] In message-passing, the sender encodes a request in an XML-based message, the receiver decodes the message, acts on its contents, and may send back a reply, also encoded as an XML message.
