Project: Distributed Shared White Board

In these slides, we are offering mainly guidelines for satisfactory work, but be innovative and creative, which will be valued a lot.

Team/Members Size:

1 – Individual (like Assignment 1).

General Help:

Ask your tutor during/after tutorial session. Also use “Discussion Board” in LMS.

Marks Allocated:

25

Note:

We expect all students to just finish and submit only the features noted in this specification.

Planning Proposal:

To help you in planning, we propose:

  • Basic Features (first complete a system with these features as they are easier to implement)
  • Advanced Features

Main Challenges

Dealing with concurrency

Regardless of the technology you use, you will have to ensure that access to shared resources is properly handled and that simultaneous actions lead to a reasonable state.

Structuring your application and handling the system state

For example, you can have multiple servers that communicate with each other or a single central one that manages all the system state.

Dealing with networked communication

You need to decide when/what messages are sent across the network. You may have to design an exchange protocol that establishes which messages are sent in which situation and the replies that they should generate. If you use RMI, then you need to design your remote interface(s) and servants.

Implementing the GUI

The functionality can resemble tools like MS Paint. You can use any tool/API/library you want. For example, the Java2D drawing package is available at: http://docs.oracle.com/javase/tutorial/2d/index.html
