| 11 | 6 | Greg Burri | h3. [[FileManager]] |
| 12 | |||
| 13 | 12 | Greg Burri | * Kept up to date a list of shared files. |
| 14 | * Cuts file in chunks. |
||
| 15 | * Each chunk has a hash and can be read or write. |
||
| 16 | * Can make fast search with indexed words. |
||
| 17 | 17 | Greg Burri | * Can return the chunk associated to a given hash code. |
| 18 | 12 | Greg Burri | * The directory structure can be browse. |
| 19 | * Theses data (files/dirs/chunks/hashes) are persisted to avoid re-hashing. |

| 22 | 8 | Greg Burri | h3. [[NetworkListener]] |
| 23 | |||
| 24 | 1 | Greg Burri | * Listens for new TCP connections from peers. Forward it to the _PeerManager_. |
| 25 | * Listens for new UDP datagrams. |
||
| 26 | 12 | Greg Burri | * Provides some interfaces to listen some events. |
| 27 | ** New chat message. |
||
| 28 | ** New search result. |
||
| 29 | 9 | Greg Burri | * Sent periodically an UDP datagram to show its presence. |
| 30 | 12 | Greg Burri | ** This message contains the top chunks. |
| 31 | 16 | Greg Burri | ** For each chunk the known IP's are given to the _DownloadManager_. |

| 33 | |||
| 34 | 1 | Greg Burri | h3. [[DownloadManager]] |
| 35 | 8 | Greg Burri | |
| 36 | 12 | Greg Burri | * Has a download queue with different status. |
| 37 | 1 | Greg Burri | * Has a pool of downloader which will choose a free chunk and : |
| 38 | 12 | Greg Burri | ** Ask the chunk's peer source for the hashes if they are unknown. |
| 39 | ** Download it from a known peer. |

| 41 | 9 | Greg Burri | h3. [[UploadManager]] |
| 42 | 1 | Greg Burri | |
| 43 | 9 | Greg Burri | * Listens the _PeerManager_ for new upload requests. |
| 44 | * Manage a pool of uploaders which will read a chunk from _FileManager_ and send it to the remote peer. |
||
| 45 | |||
| 46 | 8 | Greg Burri | |
| 47 | h3. [[PeerManager]] |
||
| 48 | 10 | Greg Burri | |
| 49 | 12 | Greg Burri | * Knows all other peers and different information about them like nick, amount of sharing and speed transfer. |
| 50 | 10 | Greg Burri | * Each peer has a connection (socket) pool. |
| 51 | * Treats new messages (unicast) from other peers. |
||
| 52 | |||
| 53 | 12 | Greg Burri | |
| 54 | 13 | Greg Burri | h3. [[RemoteControlManager]] |
| 55 | 11 | Greg Burri | |
| 56 | * Manages all connections from remote controllers. |
||
| 57 | * Send periodically the state of the core to the controllers. |
||
| 58 | 12 | Greg Burri | * Send asynchronous events to the controllers. |
| 59 | 11 | Greg Burri | * Dispatch the controllers commands. |

| 68 | |||
| 69 | 7 | Greg Burri | * Logs some kind of severity messages |
| 70 | 5 | Greg Burri | * Can store the log in a file |
