Media Objects

In 1999, exchanges of digital media objects, especially files of music, came to constitute a significant portion of Internet traffic, thanks to a new set of technologies known as peer-to-peer (P2P) file-sharing systems. The networks created by software applications such as Napster and Kazaa have made it possible for millions of users to gain access to an extraordinary range of multimedia files. However, the digital product characteristics of portability and replicability have posed great challenges for businesses that have in the past controlled the markets for image and sound recordings. ‘Peer-to-peer’ is a type of network architecture in which the various nodes may communicate directly with other nodes, without having to pass messages through any central controlling node (Whinston, Parameswaran, & Susarla, 2001). The basic infrastructure of the Internet relies on this principle for fault tolerance; if any single node ceases to operate, messages can still reach their destination by rerouting through other still-functioning nodes. The Internet today consists of a complex mixture of peer-to-peer and client-server relationships, but P2P file-sharing systems operate as overlay networks (Gummadi, Saroiu, & Gribble, 2002) upon that basic Internet structure. P2P file-sharing systems are software applications which enable direct communications between nodes in the network. They share this definition with other systems used for purposes other than file sharing, such as instant messaging, distributed computing, and media streaming. What these P2P technologies have in common is the ability to leverage the combined power of many machines in a network to achieve results that are difficult or impossible for single machines to accomplish. However, such networks also open up possibilities for pooling the interests and actions of the users so that effects emerge which were not necessarily anticipated when the network technology was originally created (Castells, 2000). In a narrow sense, P2P file-sharing systems refer to applications that exchange content over computer networks where the nodes act both as client and server machines, requesting and serving files (e.g., Kazaa, BitTorrent). In a wider sense, P2P file-sharing systems also include any application that lets peer users exchange digital content among themselves (e.g., YouTube, Flickr).

The Impact

Peer-to-peer (P2P) file-sharing technologies have impacted the music industry, including its strategies for the distribution of the musical products, for more than a decade now. As a result, music labels have delayed full digitization of their industry in fear of “online music piracy”. The present paper reviews the historical context of the evolution of the music industry from 1999 to 2012. Using Actor-Network theory, the paper examines the strategies that helped the music industry to translate new actors’ effect in order to sustain music labels’ business on their path to digitize music distribution. I will discuss the impact of new digital policies and methods of governing online behavior including the business concept of “entrepreneurship” as they may potentially affect the future of public domain within the framework of consumer rights.

P2p Applications

A recent survey revealed that 18 millions American Internet users, or approximately 14% of total American Internet population have peer-to-peer (P2P) file-sharing applications running on their computers (Rainie & Madden, 2004). Not surprisingly, P2P applications have become common tools for information sharing and distribution since the appearance of Napster (Napster, 2003) in 1999. P2P systems are the distributed systems in which all nodes are equal in terms of functionality and able to directly communicate with each other without the coordination of a powerful server. Anonymity, scalability, fault resilience, decentralization and self-organization are the distinct characteristics of P2P computing (Milojicic et al., 2002) compared with the traditional client-server computing. P2P computing is believed to be capable of overcoming limitations of the computing environment placed by the client-server computing model. Milojicic et al. (2002), for example, suggested that P2P computing is capable of providing improved scalability by eliminating the limiting factor, the centralized server existing in the client-server computing. In the past few years, P2P computing and its promised characteristics have caught the attention of researchers who have studied the existing P2P networks, and the advantages and disadvantage of P2P systems. Important findings include the excessive network traffic caused by flooding-based searching mechanism that must be tackled in order to fully utilize the improved scalability of P2P systems (Matei, Iamnitchi, & Foster, 2002; Portmann & Seneviratne, 2002). There were proposed efficient searching techniques targeted for both structured and unstructured P2P systems. Other research projects were conducted to study, and were intended to complement, the drawbacks brought by distinct characteristics of P2P systems. For example, the P2P users’ free-riding behavior is generally attributed to the anonymity of such form of communication (Adar & Huberman, 2000). Recent research projects have shifted to a new line of investigation of P2P networks from the economic perspective and applications of P2P systems in workplaces (Kwok & Gao, 2004; Tiwana, 2003).

Quantum Resistant Cryptography

BitTorrent (BT) is the most popular peer-to-peer file-sharing system. According to official BT information, more than 100 million active users use BT for file transfers every month. However, BT mainly relies on either a central tracker (tracker) or distributed hash table (DHT) for locating file seeders while it runs a risk of a single point of failure or cyber-attacks such as Sybil and Eclipses. To attack this problem, we proposed a Peer-to-Peer (P2P) file-sharing system called IOTA-BT by integrating BitTorrent with IOTA in this paper. The advantages of IOTA over blockchain include scalability for high throughput, compatibility with Internet of Things (IoT) footprints, zero transaction fees, partition-tolerant, and quantum-resistant cryptography. The autopeering and neighbor selection of the Coordicide of IOTA is aimed at defending a Sybil or Eclipse attack. IOTA-BT inherits these advantages from IOTA. Moreover, our experimental results have shown that the cost of executing BT functions, such as releasing torrent files and retrieving seeder information on IOTA-BT, is acceptable for improving the security of BT. IOTA-BT can indeed efficiently provide users with a P2P file-sharing environment of higher security.

Fundamental Design

Distributed systems research, and in particular ubiquitous computing, has traditionally assumed the Internet as a basic underlying communications substrate. Recently, however, the networking research community has come to question the fundamental design or ‘architecture’ of the Internet. This has been led by two observations: first, that the Internet as it stands is now almost impossible to evolve to support new functionality; and second, that modern applications of all kinds now use the Internet rather differently, and frequently implement their own ‘overlay’ networks above it to work around its perceived deficiencies. In this paper, I discuss recent academic projects to allow disruptive change to the Internet architecture, and also outline a radically different view of networking for ubiquitous computing that such proposals might facilitate.

In this thesis, we considered the effect of the content delivery network architecture on the popular short video sharing websites such as YouTube. The high number of users demanding videos impacts YouTube scalability which requires a new content delivery structure. Considering the high performance of P2P overlay networks, we propose an efficient peer-to-peer based system for short video sharing in the Internet in which all participant peers are responsible to distribute video replicas they have stored. This system comprises of a BitTorrent like network and a central media streaming server. To proficiently utilize P2P in our system, we propose some important approaches including an efficient and reliable indexing scheme, an efficient downloading strategy, a reliable content distribution mechanism, and a fairness policy. The simulations results demonstrate that the proposed system significantly increases client peers download speed while reduces the server workload and the startup delay for an improved playback quality.

Shared File

The community of peer-to-peer (P2P) file-sharing networks has been expanding swiftly since the appearance of the very first P2P application (Napster) in 2001. These networks are famous for their excellent file transfer rates and adversely, the flooding of copyright-infringed digital materials. Recently, a number of documents containing personal data or sensitive information have been shared in an unbridled manner over the Foxy network (a popular P2P network in Chinese regions). These incidents have urged the authors to develop an investigation model for tracing suspicious P2P activities. Unfortunately, hindered by the distributed design and anonymous nature of these networks, P2P investigation can be practically difficult and complicated. In this chapter, the authors briefly review the characteristics of current P2P networks. By observing the behaviors of these networks, they propose some heuristic rules for identifying the first uploader of a shared file. Also, the rules have been demonstrated to be applicable to some simulated cases. The authors believe their findings provide a foundation for future development in P2P file-sharing networks investigation.
