Multithreaded client server architecture using UDP(Java)

Deadline: 5th of July 2022 6:00pm US time Reference Code attached Topic: You will use Java to implement a simplified cloud-based storage application. – Similar to Dropbox/Google Drive, but the focus will be on the core functionalities and concurrent programming. – The user interface can be command line, standalone GUI, or web interface. – No user management, i.e., you only need to support one user, but the user could use multiple devices (clients) to connect to the server Core Functionalities: File Sync: Files must be synced continuously as changes are detected – Text and binary files, small and large files (> 200MB) – Multiple files are synced for multiple clients simultaneously • Delta Sync: Minimize the amount of data that needs to be synced, instead of syncing the entire file, every time • Sync Status: Monitor and report sync status – Sync status of each file, e.g., in or out of sync, sync progress for each file that is currently being synced • Error Handling: Data consistency must be preserved in all situations, e.g., network failure, user errors, and others. Technical requirements: Data transmission must be implemented using UDP, i.e., not TCP – Commands can be sent/received using TCP. • Files must be managed and transmitted using blocks – Recommended block size: 4MB – Block retransmission should be minimized. • Maximum Concurrency: Create as many threads as needed to maximize computation efficiency – As a basic requirement, separate threads must be used for syncing different files, command vs data transmission, file read/write vs network send/receive, and status monitoring.
