With the rapid progress in networking and computing technologies, a wide variety of network-based computing applications have been developed and deployed on the internet. Flexible and effective service provisioning for supporting the diverse applications is a key requirement for the next generation internet. However, the current internet lacks sufficient capability for meeting this requirement, mainly due to the ossification caused by tight coupling between network architecture and infrastructure. Service-Oriented Architecture (SOA), which has been widely adopted in cloud computing via the Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) paradigms, may be applied in networking to decouple network architecture and infrastructure; thus offering a promising approach to addressing some fundamental challenges to the next generation Internet. In general, such a service-oriented networking paradigm is referred to as Network-as-a-Service (NaaS). This book presents the state of the art of the NaaS paradigm, including its concepts, architecture, key technologies, applications, and development directions for future network service provisioning. It provides readers with a comprehensive reference that reflects the most current technical developments related to NaaS.

A manifesto for the humanities in the digital age, A New Republic of Letters argues that the history of texts, together with the methods by which they are preserved and made available for interpretation, are the overriding subjects of humanist study in the twenty-first century. Theory and philosophy, which have grounded the humanities for decades, no longer suffice as an intellectual framework. Jerome McGann proposes we look instead to philology—a discipline which has been out of fashion for many decades but which models the concerns of digital humanities with surprising fidelity.

For centuries, books have been the best way to preserve and transmit knowledge. But as libraries and museums digitize their archives and readers abandon paperbacks for tablet computers, digital media are replacing books as the repository of cultural memory. While both the mission of the humanities and its traditional modes of scholarship and critical study are the same, the digital environment is driving disciplines to work with new tools that require major, and often very difficult, institutional changes. Now more than ever, scholars need to recover the theory and method of philological investigation if the humanities are to meet their perennial commitments. Textual and editorial scholarship, often marginalized as a narrowly technical domain, should be made a priority of humanists’ attention.

This report presents a quantitative assessment of how the presentation of news has changed over the past 30 years and how it varies across platforms. Over time, and as society moved from “old” to “new” media, news content has generally shifted from more-objective event- and context-based reporting to reporting that is more subjective, relies more heavily on argumentation and advocacy, and includes more emotional appeals.

A digital anthropologist examines the online lives of millions of people in China, India, Brazil, and across the Middle East—home to most of the world’s internet users—and discovers that what they are doing is not what we imagine.

New-media pundits obsess over online privacy and security, cyberbullying, and revenge porn, but do these things really matter in most of the world? The Next Billion Users reveals that many assumptions about internet use in developing countries are wrong.

After immersing herself in factory towns, slums, townships, and favelas, Payal Arora assesses real patterns of internet usage in India, China, South Africa, Brazil, and the Middle East. She finds Himalayan teens growing closer by sharing a single computer with common passwords and profiles. In China’s gaming factories, the line between work and leisure disappears. In Riyadh, a group of young women organizes a YouTube fashion show.

Why do citizens of states with strict surveillance policies appear to care so little about their digital privacy? Why do Brazilians eschew geo-tagging on social media? What drives young Indians to friend “foreign” strangers on Facebook and give “missed calls” to people? The Next Billion Users answers these questions and many more. Through extensive fieldwork, Arora demonstrates that the global poor are far from virtuous utilitarians who mainly go online to study, find jobs, and obtain health information. She reveals habits of use bound to intrigue everyone from casual internet users to developers of global digital platforms to organizations seeking to reach the next billion internet users.
