P2p Networks Rock Case Study Solution

Newtrax Technologies Inc., based in Montreal, Canada, is a leading provider of safety and productivity solutions to the global underground hard rock mining industry.  We enable underground hard rock mines to measure KPIs they were not able to measure before, in real-time, to enable short-interval control of operations during the shift. This includes real-time KPIs for drills, trucks, bolters, and LHDs with coverage all the way to the face, and a full-suite of KPIs without operator input using passive data collection.

Newtrax solutions leverage any existing network infrastructure and enhance network connectivity with the MineHop™ battery-powered wireless multihop network and MineProx™ adhoc peer-to-peer network. Purpose-built to fill the gaps in existing communications systems in underground mines, these unique network extensions can cost-effectively cover all parts of the mining process, including the face, for real-time identification of productivity bottlenecks and early warnings of safety, health and environmental hazards.

Newtrax’s focus on mining began in 2009 and the company’s main market is mid-tier and top-tier underground hard rock mechanized mines. Our customers include 50+ of the largest producers of gold, silver, platinum, copper, nickel, zinc, lead, uranium and other base metals on all 5 continents.

 

Later companies and projects successfully followed its P2P file sharing example such as Gnutella, Freenet, Kazaa, and many others. Some services, like LimeWire, Scour, Grokster, Madster, and eDonkey2000, were brought down or changed due to similar circumstances.

BitTorrent BitTorrent 

 is a protocol for the practice of peer-to-peer file sharing that is used to distribute large amounts of data over the Internet. BitTorrent is one of the most common protocols for transferring large files, and peer-to-peer networks have been estimated to collectively account for approximately 43% to 70% of all Internet traffic (depending on geographical location) as of February 2009. In November 2004, BitTorrent was responsible for 35% of all Internet traffic. As of February 2013, BitTorrent was responsible for 3.35% of all worldwide bandwidth, more than half of the 6% of total bandwidth dedicated to file sharing. Programmer Bram Cohen, a former University at Buffalo graduate student in Computer Science, designed the protocol in April 2001 and released the first available version on 2 July 2001, and the final version in 2008. BitTorrent clients are available for a variety of computing platforms and operating systems including an official client released by Bittorrent, Inc. As of January 2012, BitTorrent is utilized by 150 million active users (according to BitTorrent, Inc.). Based on this figure, the total number of monthly BitTorrent users can be estimated at more than a quarter of a billion.

 Advantages

Higher speed

Enable to transfer bigger file

Limitations

Speed depends on no. of peers

Problem with streaming file

1. How can P2P file-sharing networks make money if they do not sell music?

Many P2P file-sharing networks obtain revenue from advertising. They can also use a subscription or a pay-for-download business model in conjunction with offering P2P file sharing.

2. Into which category or categories of e-commerce do P2P file-sharing networks fall?

P2P file-sharing networks fall primarily into the P2P category of e-commerce. However, many P2P file sharing networks can also be considered as advertising networks which may be characterized as B2B: they make money from selling access to its users to advertisers.

3. What social issues are raised by P2P file-sharing protocols and programs such as BitTorrent? Is the record industry justified in attempting to shut them down? Why or why not?

The primary social issue raised by P2P file-sharing networks is copyright infringement. You will have students taking both sides on the issue of whether the record label industry is justified in attempting to shut down P2P file-sharing networks.

4. Will the Supreme Court’s decision inhibit the development of P2

P technology or the Internet itself, as proponents of P2P services have claimed?

As with the previous question, you will have students taking both sides of the issue. Students

who claim that the Supreme Court’s decision will inhibit the development of P2P

technology can point to the fact that few new P2P networks have been created in the United States since the

Supreme Court’s decision. Students who feel that the decision will not inhibit the development

of P2P technology can point to the fact that outside the United States, P2P networks continue to flourish. Also, the decision does not prohibit use of P2P networks for lawful purposes and therefore, incentive still remains for inventors and entrepreneurs to invest in this technology. This is particularly true if they can couple the technology with a legal, revenue-producing business model.
