Devicewith Internet access

Part 1:Research Networking StandardsOrganizations

In Part 1, you will identify some of the majorstandards organizations and important characteristics, such as the number of years inexistence, the size of their membership, the important historical figures, someof the responsibilities and duties, organizational oversight role, and thelocation of the organization’s headquarters.

Use aweb browser or websites for various organizations to research information aboutthe following organizations and the people who have been instrumental inmaintaining them.

Youcan find answers to the questions below by searching the followingorganizational acronyms and terms: ISO, ITU, ICANN, IANA, IEEE, EIA, TIA, ISOC,IAB, IETF, W3C, RFC, and Wi-Fi Alliance.

1.Who is Jonathan B. Postel and what is he known for?

He was a computer scientist whomanaged the Internet Assigned Numbers Authority (IANA), playing a crucial partin the creation and administration of the Internet.

2.Which two related organizations are responsible for managing thetop-level domain name space and the root Domain Name System (DNS) name serverson the Internet?

InternetCorporation for Assigned Names and Numbers (ICANN), which operates the InternetAssigned Numbers Authority (IANA), and is in charge of maintaining the DNS rootzone.

3.Vinton Cerf has been called one of main fathers of the Internet. What Internetorganizations did he chair or help found? What Internet technologies did hehelp to develop?

InternetCorporation for Assigned Names and Numbers (ICANN) Cerf served as founding president of the Internet Society from 1992-1995, andin 1999 served a term as Chairman of the Board.

4.What organization is responsible for publishing Request for Comments(RFC)?

InternetEngineering Task Force ( IETF )

5.What do RFC 349 and RFC 1700 have in common?

Both RFC 349 and RFC 1700 have an assignednumber and both have wide standard functions. They also offer applications thatoffer link, socket, port, and protocol.

6.What RFC number is the ARPAWOCKY? What is it?

527,almost every April Fools' Day (1 April) since 1989, the Internet RFC Editor haspublished one or more humorous Request for Comments (RFC) documents, followingin the path blazed by the June 1973 RFC 527 called ARPAWOCKY, a parody of LewisCarroll's nonsense poem 'Jabberwocky.'


1.Who founded the World Wide Web Consortium (W3C)?


TheWorld Wide Web Consortium (W3C) was founded by Tim Berners-Lee after he leftthe European Organization for Nuclear Research (CERN) in October, 1994. It wasfounded at the Massachusetts Institute of Technology Laboratory for ComputerScience (MIT/LCS).


2.Name 10 World Wide Web (WWW) standards that the W3C develops andmaintains?

  • SSML
  • SVG
  • VoiceXML
  • XHTML
  • XHTML+Voice
  • XML
  • XMLEvents
  • XMLInformation Set
  • XMLSchema
  • XPath

3.Where is the Institute of Electrical and Electronics Engineers (IEEE)headquarters located and what is the significance of its logo?

Corporate office in New York Cityand its operations center in Piscataway, New Jersey, United States

4.What is the IEEE standard for the Wi-Fi Protected Access 2 (WPA2) security protocol?


Chapter 10application Of Wavesmr.

Wi-Fi Protected Access (WPA) and WPA2 areconcurrent security standards. WPA addressed the majority of the IEEE 802.11istandard; and the WPA2 certification achieved full compliance. However, WPA2will not work with some older network cards, thus the need for concurrent securitystandards


5.Is the Wi-Fi Alliance a non-profit standards organization? What is theirgoal?

Wi-FiAlliance is a non-profit organization that promotes Wi-Fi technology andcertifies Wi-Fi products if they conform to certain standards ofinteroperability. Not every IEEE 802.11-compliant device is submitted forcertification to the Wi-Fi Alliance, sometimes because of costs associated withthe certification process.

TheWi-Fi Alliance owns the Wi-Fi trademark. Manufacturers may use the trademark tobrand certified products that have been tested for interoperability

6.Who is Hamadoun Touré?


Dr.HamadounTouré, Secretary-General of the International Telecommunication Union (ITU)since January 2007, was re-elected for a second four-year term in October 2010.


7.What is the InternationalTelecommunication Union (ITU) and where is it headquartered?

TheInternational Telecommunication Union (ITU), originally the InternationalTelegraph Union is a specialized agency of the United Nations (UN) that isresponsible for issues that concern information and communication technologies.The ITU coordinates the shared global use of the radio spectrum, promotesinternational cooperation in assigning satellite orbits, works to improvetelecommunication infrastructure in the developing world, and assists in thedevelopment and coordination of worldwide technical standards. It is headquartered at Geneva Switzerland.

8.Name the three ITU sectors.

-Radio communication (ITU-R)

-Standardization (ITU-T)

-Development (ITU-D)

- ITU TELECOM

9.What does the RS in RS-232 stand for and which organization introducedit?

RS-232C. RS-232 stands forRecommend Standard number 232 and C is the latest revision of the standard. Theserial ports on most computers use a subset of the RS-232C standard.

10.What is SpaceWire?

SpaceWireis a spacecraft communication network based in part on the IEEE 1355 standardof communications. It is coordinated by the European Space Agency (ESA) incollaboration with international space agencies including NASA, JAXA and RKA.

11.What is the mission of the ISOCand where are its headquarters located?

'Topromote the open development, evolution and use of the Internet for the benefitof all people throughout the world' It is located at Reston, Virginia, US Geneva, Switzerland

12.What organizations does the IABoversee?

TheInternet Architecture Board (IAB) is the committee charged with oversight ofthe technical and engineering development of the Internet by the InternetSociety (ISoc). It oversees a number of Task Forces, of which the mostimportant are the Internet Engineering Task Force (IETF) and the InternetResearch Task Force (IRTF).

13.What organization oversees theIAB?

InternetEngineering Task Force (IETF)

ResearchTask Force (IRTF).

14.When was the ISO founded andwhere are its headquarters located?

Foundedon 23 February 1947, the organization promotes worldwide proprietary,industrial and commercial standards. It is headquartered in Geneva,Switzerland.


Part 1:Reflect on Internet and ComputerNetworking Experiences

Take amoment to think about the Internet today in relation to the organizations andtechnologies you have just researched. Then answer the following questions.

1.How do the Internet standards allow for greater commerce? What potentialproblems could we have if we did not have the IEEE?

Means you can just go online and ordersomething, instead of having to send an order via telegraph, heliograph,carrier pigeon and pony express and probably have the address translated 3times or back in 1985 or so I could send email, but it probably had to gothrough a couple of gateways between DECnet and Bitnet and Arpanet, and thereweren't any attachments, or ways to represent any language other than English,and hardly any vendors had email anyway so you'd have to use telex, or fax, orpaper documents.

2.What potential problems could we have if we did not have the W3C?


The guidelines for the Internet and theway it works will no longer be processed enough.

3.What can we learn from the example of the Wi-Fi Alliance with regard tothe necessity of networking standards?

The Alliance also certifies products thatcomply with its specifications for Wi-Fi interoperability, security andapplication-specific protocols. However, certification is not mandatory andabsence of the Wi-Fi Alliance Certified logo does not imply a lack ofcompatibility.

Description

Chapter 10 Application Of Wavesmr.'s Learning Website Learning

In network design, the gap between theory and practice is woefully broad. This book narrows it, comprehensively and critically examining current network design models and methods. You will learn where mathematical modeling and algorithmic optimization have been under-utilized. At the opposite extreme, you will learn where they tend to fail to contribute to the twin goals of network efficiency and cost-savings. Most of all, you will learn precisely how to tailor theoretical models to make them as useful as possible in practice. Throughout, the authors focus on the traffic demands encountered in the real world of network design. Their generic approach, however, allows problem formulations and solutions to be applied across the board to virtually any type of backbone communication or computer network. For beginners, this book is an excellent introduction. For seasoned professionals, it provides immediate solutions and a strong foundation for further advances in the use of mathematical modeling for network design.
