  1. Top P2P File-sharing Software (some of them )

  2. eDonkey/Overnet • Especially popular in Europe, the two P2P networks eDonkey and Overnet combined support a large base of users and files • The eDonkey P2P client connects to both networks • the Overnet client is being merged into future releases of eDonkey • eDonkey is a P2P network that relies on a centralized server structure, which holds thefile index of shared files • Unlike Napster, the dedicated server software is freely availableand therefore about 80 eDonkey servers exist • eDonkey runs on Windows, Linux and Macintosh computers • The free version of eDonkey contains embedded advertising but none of the dreaded "spyware" found in some free file sharing software

  3. eDonkey/Overnet (Cont.) • Due to the fact that every user has toauthenticate with one of these servers, the overall number of users is known at each time • On an average day in February 2005 there were between 2.8 and 3.8 million hosts connectedto the eDonkey network • sharing around 350 million files • There exist several clients for the eDonkey network • The most used ones are the officialeDonkey2000 client by eDonkey’s creator MetaMachine and the even more populareMule client • One of the main reasons for the popularity of eMule is its open sourcepolicy which permits the addition of useful features to the clients • One of the main vulnerability of the eDonkey network is its centralized server structure • Therefore the developers of eDonkey2000 and eMule started to integrate another, completelydecentralized network into their client • For the eDonkey2000 client this is Overnetand for eMule Kademlia

  4. eMule • The eMule project started with the goal of building an improved free eDonkey client • eMule has achieved a large user base, connecting both to the eDonkey P2P file sharing network and a few others • It contains no advertising, and its software base is well-maintained by an open source development team • The chief limitation of eMule's P2P file sharing program is its speed: • eMule typically performs downloading much slower than other P2P clients

  5. Gnutella • A Gnutella client has 4-10 TCP connections to other peers • For signaling traffic UDP isused and to make use of the benefits of server based networks a ”ultra-peer” state wascreated • ”Ultra-peer” status is self assigned by powerful peers and provides some extrafunctionality compared to ordinary nodes • There exist many freely available Gnutellaclients • Some of the most popular are: • Limewire • Bearshare • Morpheus • Shareaza • It has the most increasing number of users • It has a verypleasant GUI and connects also to eDonkey and BitTorrent

  6. Shareaza • Shareaza is an up-and-coming P2P file sharing program • This client offers an extremely powerful search engine capable of connecting to multiple popular P2P networks including eDonkey, BitTorrent and Gnutella • Shareaza file sharing software includes intelligence for detecting fake and/or corrupted files • The free Shareaza download also contains no ads or spyware • As the installed base of Shareaza client users grows • expect Shareaza to become an even better P2P file sharing program

  7. WinMX • WinMX offers a large P2P file sharing network and a feature-rich client program that has evolved over years of development • True, WinMX has a reputation for being complex and more difficult to use than some alternatives • However, WinMX also provides power to users in managing their downloads, and it offers a wide selection of music (MP3) files • Some WinMX users report waiting in long queues to download popular files • WinMX software runs only on the Windows family of operating systems

  8. Limewire • The Limewire P2P file sharing program connects to the Gnutella P2P network • Limewire client software is widely recognized for its clean user interface that does not contain adware • Sometimes billed as the „fastest file sharing program” • Limewire claims to offer relatively good search and download performance • Free Limewire software downloads are available for Windows, Linux and Macintosh operating systems • Limewire Pro pay clients also exist

  9. Morpheus • Morpheus P2P client application downloads exist in both free and paid Ultra versions • Compared to the free version, the Morpheus Ultra download additionally removes bundled advertising • Morpheus clients are capable of searching: • Gnutella2 • FastTrack • eDonkey2K and • Overnet P2P networks.

  10. Ares • Ares is a full-featured free P2P network with its own file sharing programs including Ares Galaxy • Ares clients support decentralized music and other file sharing and include a built-in chat service • Ares strives to offer the simplicity of Kazaa clients with no adware and fast connection times

  11. BearShare • The BearShare P2P file sharing program is a popular free software client for the Gnutella P2P network • Both free and pay downloads of BearShare file sharing programs exist

  12. KaZaA • The FastTrack network has only three official clients: • KaZaA • Grokster • iMesh • The Kazaa software family (including the Kazaa Lite family of applications) has been the single-most popular P2P file sharing program / system of all time • Kazaa is fast and easy to use • However Kazaa software and the FastTrack network it utilizes appear to be declining rapidly in popularity and availability of files • Some have criticized the intrusiveness of "adware" embedded in free Kazaa clients • Others have complained about the frequency of encountering fake files on FastTrack

  13. File sharing solutions • eDonkey2000 • FileCat • Spyster • Gnucleus • SongSpy • Toadnode • FileAngel • Gnutmeg • Shoutcast • Icecast • Socks • OpenNap • P2Pwg • AudioGalaxy • Freenet • Direct connect • Blocks • Mojo Nation • Scour • Gnutella • Bodetella • CuteMX • Freeamp • Riscter • Ezpeer • LimeWire • Napigator • iMesh • Aimster • JNerve • Jungle Monkey • BadBlue • KaZaA • Rapigator • Morpheus • Softwax • Wrapster • Gnumm • startups

  14. Importance of File Sharing • File sharing apps 5 of Top 10 downloads • By 2005 43% of broadband households • Digital photos • Digital video • Calendars • Addresses

  15. Netflow Statistics Students’ usage One hour Incoming Usage by Protocol

  16. Conclusions • P2P connects devices at the edge of the Internet • Popular in “industry” • Napster, Kazaa, etc. allow users to share data • Legal issues still to be resolved • Exciting research in academia • DHTs (Chord, Pastry, etc.) • Improve properties/performance of overlays • Applications other than file sharing are being developed
