Comparison of Direct Connect software

Last updated

This article compares features and other data about client and server software for Direct Connect, a peer-to-peer file sharing protocol.

Contents

Hub software

Direct Connect hubs are central servers to which clients connect, thus the networks are not as decentralized as Gnutella or FastTrack. Hubs provide information about the clients, as well as file-searching and chat capabilities. File transfers are done directly between clients, in true peer-to-peer fashion.

Hubs often have special areas of interest. Many have requirements on the total size of the files that their members share (share size), and restrictions on the content and quality of shares. A hub can have any arbitrary rule. Hubs can allow users to register and provide user authentication. The authentication is also in clear text. The hub may choose certain individuals as operators (similar to IRC operators) to enforce said rules if the hub itself cannot.

While not directly supported by the protocol, hub linking software exists. The software allow multiple hubs to be connected, allowing users to share and/or chat with people on the other linked hubs. Direct connect hubs have difficulty scaling, due to the broadcast-centricity of the protocol.

Client software

While not mandated by the protocol, most clients send a "tag". This is part of the client's description and display information ranging from client name and version to number of total available slots to if the user is using a proxy server. It was originally added to DC++, due to its ability to be in multiple hubs with the same instance. The information is arbitrary. The original client's file list (a comprehensive list of the files a user shares) was compressed using Huffman's compression algorithm. Newer clients (among them DC++) serve an XML-based list, compressed with bzip2.

Hub linking software links hubs' main chat, so that users can see and respond to chat that is in a hub they're not directly connected to. Often used to draw in users to hubs, or make private or small hubs more widely known. Whereas advertising a hub is "frowned upon" and is usually repercussion with floods or denial of service attacks, forming a more or less formal network by means of linking hub chat is a legitimate means for getting free publicity. Some Hub programs are able to support a more advanced form of linking which includes all the normal functions, chat, private messages, search and file transfers between users on different hubs can be supported through hub specific solutions or hub software neutral extensions using scripts/plug-ins.

<span class="mw-page-title-main">WinMX</span> Freeware peer-to-peer file sharing program

WinMX is a freeware peer-to-peer file sharing program authored in 2000 by Kevin Hearn in Windsor, Ontario (Canada). According to one study, it was the number one source for online music in 2005 with an estimated 2.1 million users. Frontcode Technologies itself abandoned development of WinMX in September 2005, but developers brought the service back online within a few days by releasing patches. WinMX continues to be used by a community of enthusiasts.

BitTorrent, also referred to as simply torrent, is a communication protocol for peer-to-peer file sharing (P2P), which enables users to distribute data and electronic files over the Internet in a decentralized manner. The protocol is developed and maintained by Rainberry, Inc., and was first released in 2001. A 2004 study by Cachelogic found that one third of all internet traffic was BitTorrent traffic.

WASTE is a peer-to-peer and friend-to-friend protocol and software application developed by Justin Frankel at Nullsoft in 2003 that features instant messaging, chat rooms, and file browsing/sharing capabilities. The name WASTE is a reference to Thomas Pynchon's novel The Crying of Lot 49. In the novel, W.A.S.T.E. is an underground postal service.

Direct Client-to-Client (DCC) is an IRC-related sub-protocol enabling peers to interconnect using an IRC server for handshaking in order to exchange files or perform non-relayed chats. Once established, a typical DCC session runs independently from the IRC server. Originally designed to be used with ircII it is now supported by many IRC clients. Some peer-to-peer clients on napster-protocol servers also have DCC send/get capability, including TekNap, SunshineUN and Lopster. A variation of the DCC protocol called SDCC, also known as DCC SCHAT supports encrypted connections. An RFC specification on the use of DCC does not exist.

RealVNC is a company that provides remote access software. Their VNC Connect software consists of a server and client application, which exchange data over the RFB protocol to allow the Viewer to control the Server's screen remotely. The application is used, for example, by IT support engineers to provide helpdesk services to remote users.

OpenVPN is a virtual private network (VPN) system that implements techniques to create secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It implements both client and server applications.

<span class="mw-page-title-main">DC++</span> Free and open-source, peer-to-peer file-sharing client

DC++ is a free and open-source, peer-to-peer file-sharing client that can be used for connecting to the Direct Connect network or to the ADC protocol. It is developed primarily by Jacek Sieka, nicknamed arnetheduck.

Private peer-to-peer (P2P) systems are peer-to-peer (P2P) systems that allow only mutually trusted peers to participate. This can be achieved by using a central server such as a Direct Connect hub to authenticate clients. Alternatively, users can exchange passwords or cryptographic keys with friends to form a decentralized network. Private peer-to-peer systems can be divided into friend-to-friend (F2F) and group-based systems. Friend-to-friend systems only allow connections between users who know one another, but may also provide automatic anonymous forwarding. Group-based systems allow any user to connect to any other, and thus they cannot grow in size without compromising their users' privacy. Some software, such as WASTE, can be configured to create either group-based or F2F networks.

The following tables compare general and technical information between a number of notable IRC client programs which have been discussed in independent, reliable prior published sources.

File sharing is a method of distributing electronically stored information such as computer programs and digital media. Below is a list of file sharing applications, most of them make use of peer-to-peer file sharing technologies.

eMule Free peer-to-peer file sharing application for Microsoft Windows.

eMule is a free peer-to-peer file sharing application for Microsoft Windows. Started in May 2002 as an alternative to eDonkey2000, eMule now connects to both the eDonkey network and the Kad network. The distinguishing features of eMule are the direct exchange of sources between client nodes, fast recovery of corrupted downloads, and the use of a credit system to reward frequent uploaders. Furthermore, eMule transmits data in zlib-compressed form to save bandwidth.
