Project Title:

Baseline Application Description:

Configuration:

• EJB
• Linux
• Java

Third-party software, if any (databases):

• MySQL
• JBoss
• LOMBOZ
• xDoclet
• MySQLConnecterJ (JDBC)
• Eclipse
• Ant

Baseline Application Features:

• Allow one player to play on one board.
• Allow the player to fill in numbers and receive feedback on the correctness.
• Allow players to create a new game.
• Allow players to start a game.
• Tell players when a game is over.

• Allow up to five players to play on one board.
• Give players 5 points for each correct answer.
• Allow players to join an existing game before any box is filled in.
• Keep track of each player's score.
• Allow players to load or generate boards.
• Tell players who won.

Reliability Requirements:

• One server crash will not affect the continuation of the game, but it is acceptable for the server to report an error to clients trying to j oin or create a game and require them to try again.
• A client request will not be lost.
• One client crash will not affect the game.
• If the client is available, a server's response will not be lost.
• The server will avoid box collisions.

Real-Time Requirements:

• All client requests, during fault-free operation, are responded to within 200 ms.
• The server, during fault-free operation, will update all clients from other clients' moves in 500 ms.
• During fault-free operation, the game will start within 1 second of the player clicking start.
• The game will resume fault-free operation in less than 2 seconds after a single server crashes.

Performance Requirements:

• The system will allow 2 to 5 clients (1 player per client) per game.
• The system will allow 100 concurrent games.
• The system will allow 100 requests / sec.
