Multicast-Group-Messenger

Implemented ISIS algorithm with modification to achieve FIFO-Total ordering of messages that is multi-casted to 5 AVDs. Ordering of the message is preserved even during the failure of the application.

Steps To Run The Program:

1. Use python-2.7 to run the commands
2. Create AVD:

python create_avd.py
python updateavd.py

3. Start the AVD:

python run_avd.py 5

4. Starting the emulator network:

python set_redir.py 10000

5. Test the program by running the grading script along with the build APK file of the program. (The grading is done in phase as mentioned below)

.\groupmessenger2-grading.exe app-debug_groupmessenger.apk

Testing Phases:

1. 4%: Group messenger provides total-FIFO ordering guarantees with messages stored in the content provider.
2. 6%: Group messenger provides total-FIFO ordering guarantees with message stored in the content provider for all correct app instances under a single app failure.
