P2P Networks and Piracy

Page 2: Peer to Peer networks and piracy

P2P = Peer to Peer(“Peer” – Rhymes with “beer”)Peers = Equals/People belonging to the same

category

A peer-to-peer computer network is a network that relies on the computing power and bandwidth of the participants in the network rather than concentrating it in a relatively low number of servers.

- Wikipedia

Page 3: Peer to Peer networks and piracy

P2P is all about sharing resources like• Your CPU Processing Time• Your bandwidth• Your disk space

Grid computing […] performs higher throughput computing by taking advantage of many networked computers to model a virtual computer architecture.

- Wikipedia

Grid computing is just sharing processing power across a network.

P2P evolved from the concept of grid computing as a means to share files between friends.

Peers:A peer is another computer on the internet that you connect to and transfer data.

Torrent:Usually this refers to the small metadata file you receive from the web server or tracker you are downloading files from.

Seeders/seeds:A computer that has a complete copy of a certain torrent. Once your

client finishes downloading, it will remain open until you click the Finish/Stop button (or otherwise close it.) This is known as being a seed or seeding.

Swarm:The group of machines that are collectively connected for a particular file. For example, if you start a BitTorrent client and it tells you that you're connected to 10 peers and 3 seeds, then the swarm consists of you and those 13 other people.

Tracker:A server on the Internet that acts to coordinate the action of BitTorrent clients.

Page 15: Peer to Peer networks and piracy

Ratio:In some torrent sites, you are expected to maintain a download to upload ratio.

Client:The program that enables p2p file sharing via the BitTorrent protocol. Examples of clients include µTorrent and Vuze.

Hash:The hash is a string of alphanumeric characters in the .torrent file that the client uses to verify the data that is being transferred.

Scrape:This is when a client sends a request to the tracking server for information about the statistics of the torrent.

Announce:A client announces that it wants to join the swarm and that server

should add it to the peers in that swarmPiece:This refers to the torrented files being divided up into equal specific

sized pieces

Darknet filesharing

• A darknet refers to any type of closed, private group of people communicating.

• These are usually private trackers such as Iptorrents.com, revolutiontt.net, bitme.org, etc.

• Private peer-to-peer systems are P2P systems that allow only mutually trusted peers to participate.

• There is a great emphasis on secrecy and privacy in such websites.
