Abstract
This paper presents a case study of the Klamath County School District's (KCSD) project to facilitate high-bandwidth learning. The paper contends that, although software solutions, such as Novell's BorderManager and SurfControl's Cyper Patrol, are cumbersome and time-consuming, they are a necessary reality for limiting violent or obscene content as required by government regulations for schools. The functionality of products such as KSCD is still necessary for performance-monitoring and remote diagnostics, but can be obtained in a single-server solution to reduce complexity and ongoing maintenance and support. The paper explains that,to maximize bandwidth capacity, network routing optimization techniques will be essential to help balance demand between low and high usage schools.
From the Paper
"The challenge KCSD faced was to provide acceptable WAN performance for core business activities. These included basic Internet and e-mail access, distance learning classes, and educational programming through broadcast and cable TV feeds. The WAN also had to support administrative applications running on top of very large databases that help the district track of students' grades, attendance, immunization records, and other critical information. In addition, the WAN was necessary for supporting Unix-based accounting systems."

DWDM, 2005.
This paper discusses the use of DWDM (dense wavelength division multiplexing) to expand telecommunications traffic.
1,090 words (approx. 4.4 pages), 5 sources, APA, $ 38.95
»
Click here to show/hide summary
Abstract
This paper explains that DWDM carries multiple optical signals across a single fiber optic cable simultaneously, but at different wavelengths so they do not interfere with each other, thus increasing its capacity because each individual signal can be transported at a different rate. The author points out that the largest stigma attached to DWDM is that, although it is reliable, at the present time virtually no companies exist, which require the enormous amount of bandwidth the system can provide. The paper relates that long distance companies have already begun to utilize the technology because DWDM provides more complex interconnect topologies as well as bandwidth capacities, which will be able to handle the telecommunications traffic of the future.
From the Paper
"When networking was first conceived the amount of bandwidth, the average individual would use was greatly underestimated. In fact, "Most U.S. networks were built using estimates that calculated bandwidth use by employing concentration ratios derived from classical engineering formulas such as Poisson and Reeling." Essentially, this meant that the engineers who devised the first networks in the United States did not foresee the enormous influx of activity generated by the internet. Therefore, the networks were built upon the assumption that the average individual would only require six minutes of bandwidth per hour; but today, with internet traffic increasing by three hundred percent per year, individual bandwidth requirements have reached upwards of one hundred eighty minutes per hour. Not surprisingly, this has created some problems. "

Abstract
The writer of this paper examines the recent growth in various alternative media sources which are grabbing more and more viewers away from the usual televised and print media into more locally controlled information sources. This paper details how various activist websites have utilized the world wide web to further their respective causes in innovative ways. For example: MoveOn.org organized a "Virtual March on Washington" where over 400,000 people signed up to flood the offices of the White House and Congress with a barrage of telephone calls and e-mails with support for a peaceful resolution to the war in Iraq. The writer contends that mainstream media tends to frame issues narrowly and in simplistic terms to avoid any real popular momentum whereas on various websites there are virtually no limits as to what can or can not be stated. With its lack of governmental oversight and unlimited bandwidth, cyberspace is finding itself, more often the first choice of those who want fast, reliable information.
From the Paper
"The true power, however, of this young medium was displayed in all its might on February 16, 2003, when "people with an astonishing variety of backgrounds and viewpoints" came out to "the biggest anti-war demonstrations ever held... worldwide." Religious organizations, race rights groups, environmentalists, anti-globalists, and others came together like a collective of Venn diagrams, independent but connecting in parts to move toward a common cause. The set up was fascinating because there was no "leader", no single set of beliefs holding these protestors together. From an organizing standpoint this type of setup has some positives and negatives. Since there is no central leadership it becomes a beast with many heads, very difficult to kill. Also, since it's arranged on the local level, the individual groups can spend time gathering up just their core constitutes by focusing on their specific agenda."

Abstract
This paper explains that Integrated Services Digital Network (ISDN) differs from the traditional form of telecommunications, namely the phone line, in that it is the reverse of standard telephone service provisioning. The author stresses that the ISDN should not be viewed as a task of communications but rather as a business solution; having verified that the ISDN service provider supports the desired features, the network designer must select the ISDN equipment and services, which support the company's business requirements. The paper relates that ISDN faces competition with such services as DSL and cable modems, which have been able to provide 10 to 20 times the bandwidth for a cheaper price; however, the one area that other services cannot beat is the voice services.
From the Paper
"ISDN brought the "third wave of internetworking to corporations and consumers." What the third wave meant is that ISDN was able to bring networks to small remote offices, individuals who telecommute and those who work from, and those who just want quicker Internets service for personal use. One downside to using ISDN is that it charges for time used. If it is used extensively, than it is more cost effective to lease a separated phone line. Also, network managers who may use ISDN need "to understand that ISDN is not always deployed to the letter of the standards set forth by the International Telecommunications Union (ITU)." "

From the Paper
"Securities Online should utilize the private stock financing option by developing an investment package available to private investors. Securities Online would create a series of A and/or B stock derived from its intrinsic worth which it could then offer to private investors that may, or may not, be venture capital investors. More often than not, this type of approach allows friends and family to invest in an objective fashion without the personal investment in the operation as a family member because rather than a personal loan they are actually receiving stock in a corporation that happens to be managed by friends or family."

Abstract
This paper discusses web traffic patterns and how the existing internet infrastructure is inadequate for the sheer amount of data and file types now moving across the web and over the Internet. It looks at how new and emerging technologies such as wireless use of the Internet to transfer media files and voice over internet protocols (VoIP) are consuming ever more bandwidth and how this affects the overall quality of service (QoS) of many of the most basic aspects of Internet usage.

From the Paper
"Quality of service or QoS allows networks to provide higher levels of service in terms of quality and efficiency by improving data flows across the network. Some of the traditional strategies to improve QoS have been to merely increase the priority levels of some data over that of others (Voice, 2005). This only works so far before it results traffic degradation system wide as all traffic becomes prioritized in order to compensate. While many companies and service providers traditionally just increased bandwidth in order to correct for QoS issues, this too is just a short-term solution to the exponentially increasing internet traffic that is resulting from the mass movement of multi-media files and data streams across the internet (IP, 2003)."

From the Paper
"Sampling is the first step in any pulse modulation system. In fact by sampling, a signal is represented by set of discrete samples. If the frequency of the sampling is high enough, the original signal can be recovered from the samples. This concept will be examined with more details later. From the mathematical point of view, the sampling process can be considered as the multiplication of the message signal by a train of Dirac impulses. "

This paper analyzes and simulates the performance of the frequency modulation (FM). The paper begins with an introduction to FM modulation and provides a full mathematical background information in regards with the FM. (This includes FM spectral analysis and introducing and simulating the role of the Bessel function and the frequency sidebands). The FM bandwidth requirements is discussed and simulated by using the MATLAB/Simulink. The simulation model and initialization steps are completely demonstrated and the results are discussed. The effect of adding noise to a FM modulated signal is analyzed and the results are presented. (This includes analysis of threshold effect and the mathematical relationship between signal to noise and carrier to noise.) The results of practical measurements are presented at the end of each part. The paper includes figures and graphs.

From the Paper
"As explained before, in FM modulation, there is a linear relation between frequency deviation and voltage variation. (At the receiver site, demodulator use this property to extract the message from the modulated signal). In other word, this means that if we sketch the graph of modulated signal frequency versus message signal's voltage for an arbitrary FM system, the slope of the graph would be a constant value and would be equal to Kf (deviation constant)."

"The impact of Internet on the traditional learning system has raised doubts in the minds of the several researchers. John and Donald assert, "Some persons are so addicted to its use to the extent they have actually flunked out of college, lost their marriage partners, become mentally sick, given up their jobs, and decreased their human contacts. Furthermore, one more researcher asserts that having access to the Internet does not assure that students will use the information accessible to them from the internet will be used to gain useful knowledge."

Abstract
This paper explains that Enron, which started in 1985 with the merger of Houston Natural Gas Company of Houston, Texas, and the natural gas company, InterNorth, based in Omaha, Nebraska, originally operated interstate gas pipelines but, in 1989, diversified into trading energy-related products. The author points out that, in addition to its trading in energy, Enron started trading in cellulose, pulp, paper, fertilizer, plastic, metals, and bandwidth. By 1999, Enron was involved in nearly a quarter of the energy deals worldwide. The paper relates that Enron's central strategy was to use totally the financial and derivatives in the market to acquire any commodities, from oil and natural gas to electric power generation and pipeline capacity, broadband communication, and freight capacity of modular containers, all at any price demanded. This corporate greed led to its downfall.
From the Paper
"Enron launched the New Power Company, the first national energy service in May 2000 along with its new strategic investors IBM and America Online. The New Power Company was created to provide energy services for residential and small businesses in the US, where deregulations in the energy market were introduced. In early 2001, Jeff Skilling took over as Enron's chief executive officer from Ken Lay. In October 2001, the tables were turned again and Ken Lay returned as chief executive officer with Jeff Skilling having resigned in August. Shortly afterwards in 2002 investigations into corporate crimes and accountancy fraud were initiated on Enron leading to sharp share prices fall and the collapse of the Enron empire."

Abstract
This paper explores the reasons for the shift from a hub-based token ring system to an Ethernet system. The author discusses the desire for increased speed, greater bandwidth and general updating of the system to be more compatible with other contemporary systems.
From the Paper
"The Ethernet originated as a laboratory project at Xerox Corporation in 1974. It was developed as an inexpensive way of sending information quickly between office machines connected together in a single room or building thus serving in essentially the same way that a local area network functions but it rapidly became a standard computer interconnection method in large measure because of the speed at which it is capable of transmitting data, which is 10 megabits per second. The Ethernet originally required a coaxial cable as its communications medium, but this is no longer the case."
