Delivery Technology

The advent of new technologies in organizations has created unprecedented challenges for professionals and managers alike to explore several cost-effective technology solutions aimed at improving communications among their target audiences. One such technology, which is gaining popularity, is streaming media. Streaming media has been around for approximately 10 years, but only now is becoming the fastest growing IT sector, with real revenues and a bright future (Alanko, 2004). Streaming media is a delivery technology that has great potential for enhancing the way people communicate and share information. The evolution of streaming media has made huge strides in the world of the Internet, from a medium which delivered unstable video streamed very slowly through inadequate networks, to one today that rivals the reach in some cases of small cable television channels and local market radio stations. The use of streaming media is becoming a mainstream communications tool in the public sector. It has the ability to enhance communications both internally and externally (i.e., important announcements, bulletins, community outreach, online learning, training, etc.). Many government departments have started offering live and archived Webcasting of numerous government meetings and programs via the Internet. Whereas outreach has previously been strictly limited to certain individuals, information is now being made available to a wider audience through the use of streaming media.

Radio Resources

Voice over Internet Protocol (VoIP) is one of the fastest growing applications for the Internet today and is a very important service because mobile users can utilize voice services more cheaply compared with most mobile systems. A crucial application over these networks is VoIP over the Worldwide Interoperability for Microwave Access (WiMAX), which is one of the technologies in Broadband Access Networks based on IEEE 802.16 standards. It provides high throughput broadband connections over long distances, which supports Point to Multi-Point (PMP) wireless access. A hurdle, however, is the number of voice connections that can be supported. Since VoIP requires short end-to-end delays, supporting as many VoIP users as possible in a mobile broadband wireless access network, considering limited radio resources, becomes a very important issue. In this chapter, the authors use a theoretical model and an algorithm to evaluate the performance of some of the most important VoIP codecs.

Bandwidth Expansion

The chapter discusses the issue of a possible abolition of network neutrality and the introduction of paid prioritization by residential broadband access networks. In short-run analysis where bandwidth is fixed and in the absence of congestion, network neutrality tends to maximize total surplus. When an ISP violates network neutrality and invests the extra profits to bandwidth expansion, the presence of more bandwidth alleviates the allocative distortion, and can even reverse it. The chapter discusses the network neutrality issue under the assumption of congestion, and characterizes the set of utility functions for which network neutrality is optimal, as well as utility functions where it is optimal to prioritize. The chapter also reviews regulatory rules in the United States on network neutrality.

В настоящее время желание клиентов получить более высокую скорость доступа и снизить стоимость услуг за- ставляет операторов постоянно развивать свои сети. Кроме того, операторы вынуждены увеличивать размеры сетей доступа, чтобы обслужить как можно больше домохозяйств, охватить весь город, район крупного города или его окрестности в радиусе до 60 км. Также остаются актуальными проблемы ограниченного количества сервисов сети, недостаточной зоны покрытия и слишком высокой стоимости услуг для среднего абонента. Довольно много сетей все еще используют наземную беспроводную связь для организации каналов внутри или между городскими кварталами, но есть и операторы, которые используют технологию FTTH (оптоволокно до дома). В статье сравниваются производительность, пропускная способность и максимальный размер действующих сетей доступа и перспективных сетей, использующих адаптивно-модулированное оптическое ортогональное частотное мультиплексирование (AMOOFDM). Также показаны преимущества системы AMOOFDM, в которой в качестве модулятора интенсивности применяется полупроводниковый оптический усилитель. Access networks are under constant development looking for customers satisfaction by enhancing the Internet service speed and the cost of the service. However, a significant percentage of these networks still using the terrestrial radio wave telecommunications to distribute the service inside or between city blocks, while others use the fiber to the home (FTTH). The article compares the performance of the currently operated access networks to the adaptively modulated optical orthogonal frequency multiplexing (AMOOFDM) based access networks, according to the bit-rate, and the distance reach of these networks. The advantages of the AMOOFDM system, in which a semiconductor optical amplifier (SOA) is used as an intensity modulator, are shown.

AbstractThe Internet has become the main network technology supporting communications and Web services in all areas of our society. In order to perform this role efficiently, a fundamental redesign of the Internet architecture is being discussed. In particular, mobile devices and wireless access networks will constitute an important part of the Internet infrastructure. Based on a general discussion of requirements, this article focuses on the challenges of a next generation mobile Internet and discusses research approaches for mobility, addressing, heterogeneous access, and service platforms.

Streaming Media Server

The aim of this chapter is to highlight essential criteria required to set up a streaming media server within Higher Education Institutions. It explores different types of video content and highlights the importance of streaming media technology by differentiating between the traditional Web server software and streaming media server software. This is then followed by the explanation of different streaming media protocols and how the video content gets transported from the streaming media server to students’ computer. The chapter also explores different types of methods used to deliver streaming videos over the Internet, different streaming media software, encoding software, and encoding parameters used for converting high definition/quality videos into streamable quality. Section 3 of this chapter highlights the importance of folder and file naming conventions, exploring essential video metadata which is required to create and manage video files, Digital Rights Management technology to securely deliver video over the internet, and how to publish a video on the Internet.
