File Sharing

By Raul Bernardino

Introduction:

The implementation of Peer to Peer (P2P) system is often seeing as an abstract of the overlay network. The P2P application is distributing information in the computing or networking between Head Quarter (HQ) and branches offices (Close Networks) and anonymity (Open Network).

The close networks usually use intranet to distribute information among the company or the institution, including the file sharing. They use peer to peer technology to share their information by sub-netting Internet Protocol (IP).

The World Bank Group institution uses P2P technology to share information among country offices around the world. The HQ based in the Washington DC has to communicate with the rest of the offices in about 184 countries. This is the larger institution in the world. They are sharing their information and knowledge across the countries and regions, including the best practice from country to country. The sharing knowledge has based on team information and it has become huge knowledge (documents management) and it is later becomes a knowledge library. Moreover, the sharing information enable team in the fields (country based) will work more effective and efficient. Especial World Bank Group adopts matrix structure in their daily operations. Additional, to enabling the sharing the information across the globe, to be reliable, effective and efficient, the World Bank Group invests a lot of capital in the information and technology sector every year.

The United Nations institution is the second larger institution that operates in the conflict countries. They are also using a close network to disseminate information among HQ in New York and with mission operation units in the conflict or post conflict countries. Usually, the establishment of the United Nation (UN) mission in any request country has to have a good established communication in order to have an effective communication back to the HQ. For instance, in Timor-Leste, the last UN mission was United Nations Integrated Mission in Timor-Leste has direct communication with HQ by using P2P VSAT communication system. This sharing information is closed to the public.

The motivation of having the anonymity in the P2P networks are user desired. The users do not want their identities are published. The other common reasons as follows:

• The distribution of the materials are illegal
• Legal material such alcohol, people or organization intend to be anonymity
• Fear of retribution because unofficial leaks
• Censorship at local, national level, and organization
• Privacy to avoid tracking and data mining

Other companies that use P2P are:

Bittorrent: The BitTorrent Company is Software Company based in San Francisco who uses P2P to distribute for downloading. It has several features such as discovery, speedy, advance, plug and play, simple, customizable, intelligent, and reliable. I personally not test this features yet.

Pondo: Pondo is may represent future distribution media. Pondo has “solved the larger file attachment problems”, the wall street Journal Said.

SubEthaEdit: It is shared editor to allow the developers to work as the team from the different location. This is very handy tools for programmers who are developing a complex program and need a team to write a code.

Limewire: The limewire company currently registered in the court dated on October 26^th, 2010 to stop the limewire software distribution.

Microsoft: The Company uses Windows Server Update Services (WSUS) to distribute the updates to every register clients

Conclusion: The P2P communication becomes one of the available technologies to use for sharing and distributing information including updates among entities. It is also freely distributing unnecessary adware to the target clients in order to gain the information or attack with viruses.
