tailieunhanh - Technical report: An Estimate of Infringing Use of the Internet

Given the enormous, ever-growing, and constantly-changing size, shape, and consistency of the internet and the use that is made of it means that methodological issues abound when attempting to produce measurements of traffic and content. Yet even given the limitations of the data available, Envisional believes that the estimates produced in this report are more accurate than any that have been published before. This report draws together the data in a way that allows, for the first time, the organisations which can help shape the ways in which users interact and obtain content to understand how much of the internet. | Technical report An Estimate of Infringing Use of the Internet January 2011 Version Envisional Ltd Betjeman House 104 Hills Road Cambridge CB2 1LQ Telephone 44 1223 372 400 Envisional Internet bandwidth usage estimation 2 1 Introduction Envisional was commissioned by NBC Universal to analyse bandwidth usage across the internet with the specific aim of assessing how much of that usage infringed upon copyright. This report provides the results of that analysis and is in three main parts. Part A examines the internet arenas most often used for online piracy - peer-to-peer networks with a specific focus on bittorrent cyberlockers file hosting sites such as Rapidshare and other web-based piracy venues such as streaming video - and estimates the proportion of infringing content found on each. Part B is a critical analysis of recent studies from four network equipment and monitoring companies. These companies measured network traffic at multiple and different sites worldwide to characterize overall internet usage. Part C combines the data and analysis from Part A and Part B in an attempt to show what proportion of internet traffic represents unauthorised distribution of copyrighted material. Executive Summary Across all areas of the global internet of traffic was estimated to be infringing. This excludes all pornography the infringing status of which can be difficult to discern. The level of infringing traffic varied between internet venues and was highest in those areas of the internet commonly used for the distribution of pirated material. BitTorrent traffic is estimated to account for of all internet traffic. Nearly two-thirds of this traffic is estimated to be non-pornographic copyrighted content shared illegitimately such as films television episodes music and computer games and software of all bittorrent traffic or of all internet traffic . Cyberlocker traffic - downloads from sites .
