First Project

Compile and start RMI

sh compile.sh
rmiregistry

Run

Peer

Peer <version> <server id> <access_point> <MC_IP_address> <MC_port> <MDB_IP_address> <MDB_port> <MDR_IP_address> <MDR_port>

E.g.: Peer 2.0 1 Peer1 224.0.0.15 8001 224.0.0.16 8002 224.0.0.17 8003

Backup Protocol

App <host>/<peer_access_point> BACKUP <file_path> <desired_replication_degree>

E.g.: App localhost/Peer1 BACKUP C:\Users\johndoe\Documents\sdis.pdf 2

Restore Protocol

App <host>/<peer_access_point> RESTORE <file_path>

E.g.: App localhost/Peer1 RESTORE C:\Users\johndoe\Documents\sdis.pdf

Delete Protocol

App <host>/<peer_access_point> DELETE <file_path>

E.g.: App localhost/Peer1 DELETE C:\Users\johndoe\Documents\sdis.pdf

Reclaim Protocol

App <host>/<peer_access_point> BACKUP <max_amount_disk_space>

E.g.: App localhost/Peer1 RECLAIM 65000

State

App <host>/<peer_access_point> STATE

E.g.: App localhost/Peer1 STATE

Second Project

Compile and start RMI

sh compile.sh
rmiregistry

Run

Peer

Peer.Peer <version> <server id> <access_point> <MC_port> <MC_IP_address> <MDB_port> <MDB_IP_address> <MDR_port> <MDR_IP_address>

Eg.: Peer.Peer 1.0 1 1 8000 224.0.0.1 8001 224.0.0.2 8002 224.0.0.3

Backup Protocol

RMI.Application //<host>/<peer_access_point> BACKUP <file_path> <desired_replication_degree>

Eg.: RMI.Application //localhost/1 BACKUP /usr/users2/2015/Desktop/file.txt 3

Restore Protocol

RMI.Application //<host>/<peer_access_point> RESTORE <file_path>

Eg.: Application //localhost/1 RESTORE /usr/users2/2015/Desktop/file.txt

Delete Protocol

RMI.Application //<host>/<peer_access_point> DELETE <file_path>

Eg.: RMI.Application //localhost/1 DELETE /usr/users2/2015/Desktop/file.txt

Reclaim Protocol

RMI.Application //<host>/<peer_access_point> RECLAIM <max_disk_space>

Eg.: RMI.Application //localhost/1 RECLAIM 30000

State

RMI.Application //<host>/<peer_access_point> STATE

Eg.: RMI.Application //localhost/1 STATE

Notice: The Backup, Restore, Delete protocols can be called with ENH so that the enhanced version can be used.

Eg.: RMI.Application localhost/1 ENHBACKUP /usr/users2/2015/Desktop/file.txt 3
