Transcript

  • 1. Filesharing using bittorrent protocol.
  • 2. Introduction • To implement the bittorrent protocol in direct connect and server based network.
  • 3. Basic Idea Dropbox Direct connect (DC++)
  • 4. Dropbox Features File Sync File Sharing Online Backup Web Access Security Privacy Mobile Devise Access
  • 5. Internal working The software does not use any third-party file sync or version control libraries. The Dropbox client enables users to drop any file into a designated folder that is then synced with Drop box's Internet service.  focusing on synchronization and sharing
  • 6. Storing Sharing
  • 7. Syncing………
  • 8. • It has been built on a technology which makes it possible to distribute large amounts of data without the need of high capacity server and expensive bandwidth. Bittorrent Protocol

  • 10. What are peers? • A node or computer that does not have the complete file. • Perform a handshake to start the communication. • They pass a number of messages between them to send data and control the interactions.
  • 11. How Tracker Works? • Tracker is a server that manages the file transfer process. • Helps peers to find each other. • Peers request a tracker for other peers having the required pieces of data. • Tracker responds with a list of peers that have the requested piece.

  • 13. Characteristics:  Not depend on a single source.  A central server is not needed.  Prevents tampered or broken files from being shared  More the number of users, greater will be the transfer rate.  Reduces the traffic overload, because this protocol uses less bandwidth to share files across the network.

  • 15. Central server Keeps track of peers and seeds available for each file. Keeps track of files of connected nodes. Acts as a tracker of bittorrent.
  • 16. Advantage and Conclusion • No need to maintain a bulky server for client server model. • Using bittorrent protocol helps to make better use of bandwidth and faster transfer. • Each node need not be online to serve its data since there are multiple seeds.
