1. Add json.jar file from libs folder to build-path to handle json.

2. Booking ID format to be {campusName}B{4-digitID}. Example: KKLB0012

3. seperate logic into start and stop methods in server

4. udp messages format to be {4-digit-sequenceNumber}-={function}-={param1}-={param2} etc.

   Example:

   Function	Message Format
   createRoom	0001-=create-={adminID}-={roomNum}-={date}-={timeslots(comma seperated)}
   deleteRoom	0002-=delete-={adminID}-={roomNum}-={date}-={timeslots(comma seperated)}
   bookRoom	0003-=book-={studentID}-={campusName}-={roomNumber}-={date}-={timeslot}
   changeReservation	0004-=change-={studentID}-={oldBookingID}-={campusName}-={roomNumber}-={date}-={timeslot}
   cancelBooking	0005-=cancel-={studentID}-={bookingID}
   getAvailableTimeSlots	0006-=availability-={studentID}-={date}

5. FrontEnd UDP Message to Replica Manager to be of formats

   • error:not-available if server is not available.
   • error:{expected_correct_answer} if wrong response.

6. Server response messages:

   Function	Success Message	Failure Message
   createRoom	success	failed
   deleteRoom	success	failed
   bookRoom	success: {bookingID}	failed
   changeReservation	success: {bookingID}	failed
   cancelBooking	success	failed
   getAvailableTimeSlots	success: KKL0 DVL0 WST0	failed

7. Ports

   Component	Port
   FrontEnd	4001
   Sequencer	5001
   ReplicaManger	6001
   KKL Server	7001
   DVL Server	7002
   WST Server	7003

8. JSON format for representing database is available in file

P.S. { } in above formats needs to be excluded in actual implementation.
