SDIS: PROJECT 2 - Distributed Backup Service for The Internet

Second Project for the Distributed Systems (SDIS) class of the Master in Informatics and Computer Engineering (MIEIC) at the Faculty of Engineering of the University of Porto (FEUP). Detailed Report in the repository, Report.pdf

Installing

Compile all the source files

javac *.java

Running

Peer

First Peer

The First Peer to enter the ChordRing must create it

Peer <peer_id> <ip_Adress> <port_Number> CREATE

E.g.: java Peer 1 localhost 8888 create

Rest of Peers

To all the other Peers you must provide and IpAdress and Port of a Peer that already is on the ChordRing

Peer <peer_id> <ip_Adress> <port_Number> JOIN  <chord_Member_Ip_Address> <Chord_Member_Port_Number>

E.g.: java Peer 2 localhost 8000 join localhost 8888

Client Interface

The Client Interface provides the services availables to the Peers:

  • Backup Protocol: Insert the file path of your file and your desired number of copies to enter into the System
  • Restore Protocol: Insert the file path of the file that you want to restore from the system (The file must be previously put into the System by the user)
  • Delete Protocol: Insert the file path of the file that you want to delete from the system (The file must be previously put into the System by the user)
  • Reclaim Protocol: Insert the max amount of memory you want to provide to the System (KBytes)
  • State : Get information of the files you put into the System, the files you are storing for other Peers and your Node information on the ChordRing

Backup Protocol

ClientInterface <peer_id> BACKUP <file_path> <desired_replication_degree>

E.g.: ClientInterface 1 BACKUP test/souto.html 2

Restore Protocol

ClientInterface <peer_id> RESTORE <file_path>

E.g.: ClientInterface 1 RESTORE test/souto.html

Delete Protocol

ClientInterface <peer_id> DELETE <file_path>

E.g.: ClientInterface 1 DELETE test/souto.html

Reclaim Protocol

ClientInterface <peer_id> BACKUP <max_amount_disk_space>

E.g.: ClientInterface 1 RECLAIM 65000

State

ClientInterface <peer_idt> STATE

E.g.: ClientInterface 1 STATE
