“…The difficulties experienced in case of packet losses due to the error recovery mechanism of TCP were alleviated using spooling the received data stream for 4-8 s in memory. The required data rates (300 Mbps) were achieved by utilizing an enlarged TCP >1 Gbps [19][20][21][22][23] window (4 MB), multiple concurrent TCP connections (64), and traffic shaping function to control the data transmission quality and bursty nature. The authors also describe the developed system in some detail in [16], utilizing the same test-bed and achieving transmission speed of 500 Mbps.…”

“…The techniques are described in the context of two application areas of (1) high resolution visualisation in science and (2) high-quality real-time consumer video applications over optical networks. The work in [20] described the architecture of High Performance Digital Media Network (HPDMnet) [35], which is a global experimental end-to-end network that can support high resolution imaging, 3D movies, and 4/8K streams. The test-bed was used for many-to-many streaming where each site was sending 1.5 Gbps stream and receiving two such streams from the other sites over geographically distributed locations.…”

Digital technology has transformed the information flow and support infrastructure for numerous application domains, such as cellular communications. Cinematography, traditionally, a film based medium, has embraced digital technology leading to innovative transformations in its work flow. Digital cinema supports transmission of high resolution content enabled by the latest advancements in optical communications and video compression. In this paper we provide a survey of the optical network technologies for supporting this bandwidth intensive traffic class. We also highlight the significance and benefits of the state of the art in optical technologies that support the digital cinema work flow.

“…In this paper, the starting point for the guaranteed data rate per subscriber is established initially at 30 Mbps in fixed networks and 1 Mbps in mobile networks. These are reference values for each technology that cover the current needs for more demanding data applications (Jukan & Mambretti, 2012;Radio, Ying, Tatipamula, & Madisetti, 2012).…”

“…The objective figures for 2020 are set at 100 Mbps for fixed networks and 5 Mbps for mobile networks, in conjunction with policy (EC, 2010a) and current industrial perspectives (Jukan & Mambretti, 2012;Radio et al, 2012). In particular, in fixed networks, the guaranteed data rate is assumed to increase from 30 Mbps to 50 Mbps by 2016 and to 100 Mbps by 2020.…”

The contribution to global energy consumption of the information and communications technology (ICT) sector has increased considerably in the last decade, along with its growing relevance to the overall economy. This trend will continue due to the seemingly ever greater use of these technologies, with broadband data traffic generated by the usage of telecommunication networks as a primary component. In fact, in response to user demand, the telecommunications industry is initiating the deployment of next generation networks (NGNs). However, energy consumption is mostly absent from the debate on these deployments, in spite of the potential impact on both expenses and sustainability.[n addition, consumers are unaware of the energy impact of their choices in ultra-broadband services. This paper focuses on forecasting energy consumption in the access part of NGNs by modelling the combined effect of the deployment of two different ultra-broadband technologies (FTTH-GPON and LTE), the evolution of traffic per user, and the energy consumption in each of the networks and user devices. Conclusions are presented on the levels of energy consumption, their cost and the impact of different network design parameters. The effect of technological developments, techno-economic and policy decisions on energy consumption is highlighted. On the consumer side, practical figures and comparisons across technologies are provided. Although the paper focuses on Spain, the analysis can be extended to similar countries.

Many important societal activities are global in scope, and as these activities continually expand world-wide, they are increasingly based on a foundation of advanced communication services and underlying innovative network architecture, technology, and core infrastructure. To continue progress in these areas, research activities cannot be limited to campus labs and small local testbeds or even to national testbeds. Researchers must be able to explore concepts at scaleto conduct experiments on world-wide testbeds that approximate the attributes of the real world. Today, it is possible to take advantage of several macro information technology trends, especially virtualization and capabilities for programming technology resources at a highly granulated level, to design, implement and operate network research environments at a global scale. GENI is developing such an environment, as are research communities in a number of other countries. Recently, these communities have not only been investigating techniques for federating these research environments across multiple domains, but they have also been demonstration prototypes of such federations. This chapter provides an overview of key topics and experimental activities related to GENI international networking and to related projects throughout the world.
