5 separate programs split between senders and receivers running concurrently

Main Project:

• Create 2 Receivers and 3 Senders where the Senders are sending data to the Receivers.
• The 5 Programs are running concurrently on the same machine.

Jobs

Sender

• Create a random 32 bit number generator for each of the senders
• Assign and store the values 251, 257, or 997 to the respective project where each of the senders will behave differently
• Sender #997
  • Sends to who:
    • Sends each event to ALL RECEIVERS
  • Requirements:
    • Requires acknowledgement for each message from BOTH RECEIVERS before it continues execution
  • Termination cause:
    • Terminates when it gets/observes a RANDOM NUMBER SMALLER THAN 100
• Sender #251
  • Sends to who:
    • Sends each event to only ONE RECEIVER
  • Requirements:
    • Does not accept any acknowledgement messages
  • Termination cause:
    • Terminates on a “KILL” COMMAND FROM A SEPARATE TERMINAL
    • The above will be supplied by the professor as a patch code to be integrated with this sender
• Sender #257
  • Sends to who:
    • Sends each event to only ONE RECEIVER
  • Requirements:
    • Does not accept any acknowledgement messages
  • Termination cause:
    • Terminates when ITS RECEIVER STOPS RECEIVING EVENT NOTIFICATIONS

Receiver

• Each receiver repeatedly gets a message and displays the value and the Sender’s identity
• Receiver #1
  • Accepts from who:
    • Only accepts messages from 251 AND 997 SENDERS
  • Termination cause:
    • Terminates after BOTH OF ITS SENDERS HAVE TERMINATED
• Receiver #2
  • Accepts from who:
    • Only accepts messages from 257 AND 997 SENDERS
  • Termination cause:
    • Terminates after it has RECEIVED A TOTAL OF 5000 MESSAGES
