11 | 20 | Greg Burri | h3. [[FileManager]] (FM) |
12 | 6 | Greg Burri | |
13 | 21 | Greg Burri | * Keep up to date a list of shared files. |
14 | * Cut file in chunks. |
||
15 | 12 | Greg Burri | * 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 | 20 | Greg Burri | h3. [[NetworkListener]] (NL) |
23 | 8 | Greg Burri | |
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 | 18 | Greg Burri | ** This message contains the top needed chunks given by the _DownloadManager_. |
31 | ** For each answer the known IPs associated to a chunk are given to the _DownloadManager_. |

33 | |||
34 | 20 | Greg Burri | h3. [[DownloadManager]] (DM) |
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 | 20 | Greg Burri | h3. [[UploadManager]] (UM) |
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 | |||

47 | 20 | Greg Burri | h3. [[PeerManager]] (PM) |
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 | 19 | Greg Burri | * Treats new messages (TCP) from other peers. |
52 | 10 | Greg Burri | |
53 | 12 | Greg Burri | |
54 | 20 | Greg Burri | h3. [[RemoteControlManager]] (RCM) |
55 | |||
56 | 11 | Greg Burri | * 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. |
