The Edonkey File-Sharing Network
The eDonkey File-Sharing Network Oliver Heckmann, Axel Bock, Andreas Mauthe, Ralf Steinmetz Multimedia Kommunikation (KOM) Technische Universitat¨ Darmstadt Merckstr. 25, 64293 Darmstadt (heckmann, bock, mauthe, steinmetz)@kom.tu-darmstadt.de Abstract: The eDonkey 2000 file-sharing network is one of the most successful peer- to-peer file-sharing applications, especially in Germany. The network itself is a hybrid peer-to-peer network with client applications running on the end-system that are con- nected to a distributed network of dedicated servers. In this paper we describe the eDonkey protocol and measurement results on network/transport layer and application layer that were made with the client software and with an open-source eDonkey server we extended for these measurements. 1 Motivation and Introduction Most of the traffic in the network of access and backbone Internet service providers (ISPs) is generated by peer-to-peer (P2P) file-sharing applications [San03]. These applications are typically bandwidth greedy and generate more long-lived TCP flows than the WWW traffic that was dominating the Internet traffic before the P2P applications. To understand the influence of these applications and the characteristics of the traffic they produce and their impact on network design, capacity expansion, traffic engineering and shaping, it is important to empirically analyse the dominant file-sharing applications. The eDonkey file-sharing protocol is one of these file-sharing protocols. It is imple- mented by the original eDonkey2000 client [eDonkey] and additionally by some open- source clients like mldonkey [mlDonkey] and eMule [eMule]. According to [San03] it is with 52% of the generated file-sharing traffic the most successful P2P file-sharing net- work in Germany, even more successful than the FastTrack protocol used by the P2P client KaZaa [KaZaa] that comes to 44% of the traffic. -

Marcia Knous: My Name Is Marcia Knous
Olivia Ryan: Can you just state your name? Marcia Knous: My name is Marcia Knous. OR: Just give us your general background. How did you come to work at Mozilla and what do you do for Mozilla now? MK: Basically, I started with Mozilla back in the Netscape days. I started working with Mozilla.org shortly after AOL acquired Netscape which I believe was in like the ’99- 2000 timeframe. I started working at Netscape and then in one capacity in HR shortly after I moved working with Mitchell as part of my shared responsibility, I worked for Mozilla.org and sustaining engineering to sustain the communicator legacy code so I supported them administratively. That’s basically what I did for Mozilla. I did a lot of I guess what you kind of call of blue activities where we have a process whereby people get access to our CVS repository so I was the gatekeeper for all the CVS forms and handle all the bugs that were related to CVS requests, that kind of thing. Right now at Mozilla, I do quality assurance and I run both our domestic online store as well as our international store where we sell all of our Mozilla gear. Tom Scheinfeldt: Are you working generally alone in small groups? In large groups? How do you relate to other people working on the project? MK: Well, it’s a rather interesting project. My capacity as a QA person, we basically relate with the community quite a bit because we have a very small internal QA organization. -

TRANSFERENCIA O DISTRIBUCIÓN DE ARCHIVOS ENTRE IGUALES (peer-to-peer) Características, Protocolos, Software, Luis Villalta Márquez Configuración Peer-to-peer Una red peer-to-peer, red de pares, red entre iguales, red entre pares o red punto a punto (P2P, por sus siglas en inglés) es una red de computadoras en la que todos o algunos aspectos funcionan sin clientes ni servidores fijos, sino una serie de nodos que se comportan como iguales entre sí. Es decir, actúan simultáneamente como clientes y servidores respecto a los demás nodos de la red. Las redes P2P permiten el intercambio directo de información, en cualquier formato, entre los ordenadores interconectados. Peer-to-peer Normalmente este tipo de redes se implementan como redes superpuestas construidas en la capa de aplicación de redes públicas como Internet. El hecho de que sirvan para compartir e intercambiar información de forma directa entre dos o más usuarios ha propiciado que parte de los usuarios lo utilicen para intercambiar archivos cuyo contenido está sujeto a las leyes de copyright, lo que ha generado una gran polémica entre defensores y detractores de estos sistemas. Las redes peer-to-peer aprovechan, administran y optimizan el uso del ancho de banda de los demás usuarios de la red por medio de la conectividad entre los mismos, y obtienen así más rendimiento en las conexiones y transferencias que con algunos métodos centralizados convencionales, donde una cantidad relativamente pequeña de servidores provee el total del ancho de banda y recursos compartidos para un servicio o aplicación. Peer-to-peer Dichas redes son útiles para diversos propósitos. -

Darmstadt University of Technology The eDonkey 2000 Protocol Oliver Heckmann, Axel Bock KOM Technical Report 08/2002 Version 0.8 December 2002 Last major update 22.05.03 Last minor update 27.06.03 E-Mail: {heckmann, bock}@kom.tu-darmstadt.de Multimedia Communications (KOM) Department of Electrical Engineering & Information Technology & Department of Computer Science Merckstraße 25 • D-64283 Darmstadt • Germany Phone: +49 6151 166150 Fax: +49 6151 166152 Email: [email protected] URL: http://www.kom.e-technik.tu-darmstadt.de/ 1. Introduction The Edonkey2000 Protocol is one of the most successful file sharing protocols and used by the original Edonkey2000 client and the open source clients mldonkey and EMule. The Edonkey2000 Protocol can be classified as decentral file sharing protocol with distributed servers. Contrary to the original Gnutella Protocol it is not completely decentral as it uses servers; contrary to the original Napster protocol it does not use a single server (farm) which is a single point of failure, instead it uses servers that are run by power users and offers mechanisms for inter-server communication. Unlinke Peer-to-Peer (P2P) proto- cols like KaZaa, Morpheus, or Gnutella the eDonkey network has a client/server based structure. The servers are slightly similar to the KaZaa supernodes, but they do not share any files, only manage the information distribution and work as several central dictionaries which hold the information about the shared files and their respective client locations. In the Edonkey network the clients are the nodes sharing data. Their files are indexed by the servers. If they want to have a piece of data (a file), they have to connect using TCP to a server or send a short search request via UDP to one or more servers to get the necessary information about other clients sharing that file. -

This began with point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of networks. In 1982 the Internet Protocol Suite (TCP/IP) was standardized and the concept of a world-wide network of fully interconnected TCP/IP networks called the Internet was introduced. -

With the development of global business, MNEs are always sinking into various pressures which are related to economic factors, social factors and informational factors. This situation making MNEs’ strategies is supposed to achieve those requirements that including global market integration, national responsiveness, worldwide learning. There are four important strategies which are widely used in MNEs internationalization process that including multinational strategy, global strategy, international strategy, and transnational strategy. This essay will introduce pursuing transnational strategy and some difficulties existing in this process. Furthermore, an example of an entrepreneurial subsidiary will be chosen to explore and conduct further research. autonomy thus more difficult for the parent company to 1 INTRODUCTION manage them. The modern transnational strategy is attempting to be simultaneously both globally coordinated Getting benefits from the development of global business, and locally responsive. This strategy is not only MNEs are becoming one of the most pervasive types of emphasizing decentralized, interdependent, and business organization. A multinational enterprise is one specialized characteristics in MNEs' configuration of which controls -
