FileManager

  • Kept up to date the list of shared files
  • Can make fast search with indexed words
  • Cuts file in chunks
  • Each chunk has a hash and can be read or write

    • This message contains the top chunks
    • For each chunk the known IP's are gave to the DownloadManager

DownloadManager

  • Has a download list with different status
  • Has a pool of downloader which will choose a free chunk and :
    • Download it from a know peer.
    • Ask first the chunk's peer source for the hashes if they are unknown

UploadManager

  • Listens the PeerManager for new upload requests.
  • Manage a pool of uploaders which will read a chunk from FileManager and send it to the remote peer.

PeerManager

  • Knows all other peers and different information about them like nick, amount of sharing and speed.
  • Each peer has a connection (socket) pool.
