The Challenge of Future Communications

The globalization of Internet access and Web 2.0 services has led to profound changes in the nature and context of communications. Traditionally, communication meant to transmit a message to a certain person in a concrete moment in time, and so it was one-to-one and occasional. With the success of social networks, communications have become pervasive; people are communicating all the time, feeling connected, expressing themselves, sharing their lifestyle. The model is now asynchronous and one-to-many. These emerging needs are today primarily being met by Internet players who are leading innovation in communications better than old operators. These new players arise offering to the users very simple, appealing and focused services that satisfy some of their communication needs much better than old operators do. But not only new ways of communication come up. Most of these new communication services are even free, changing the traditional business models and causing the global communication scenario to change. However, traditional operators still handle most of the synchronous voice communications with landline and mobile services that satisfy other more intimate user needs. With all this information, the challenge for communications in the future is to find the user needs behind all the different services use cases and build a new communication environment based on simplicity, socialization, security and privacy, to take the traditional services to the next stage.

Building the Future Telecommunications: Services and Networks of Internet

Internet has become the global hub for information and communication where different actors, whether businesses, communities or individuals, connect with each other, share their contents, and want to be aware of their context. They are connected to social networks and virtual worlds, sharing knowledge within a given community. They want all those features to be accessible anywhere, anytime and on any device, but they also want to protect their privacy. To achieve that ambitious objective a strategic agenda is required. This overall plan would help to build the Telecommunications of the future, establish priorities and indicate the different interrelations. In this paper, we identify the current major research lines, provide a classification and indicate which could be the major research outcomes for the coming years. Download

Engineering Future Network Governance

Information and Communications Technologies (ICT) are transforming the world with computing, storage and communications resources being ubiquitous commodities. At the same time, the operation and management of this infrastructure is becoming more and more complex, requiring an increasing amount of resources and effort that currently exceed the cost of their own infrastructure. This trend is pushing operation and management to be the main challenge for the ICT industry. From the network operation point of view, the drastic change is that it is not possible to have an easy end-to-end view on how services are delivered and the pace of changes in services, topology, etc. Current Operational and Support Systems (OSS´s) used to manage the infrastructures are designed for different requirements and are not able to provide effective help for such dynamic and uncertain environments. Autonomic Computing and Communications promise to develop a self-management infrastructure and seem to offer a solution to make operational processes simpler. The EU funded EFIPSANS (Exposing the Features in IP version Six protocols that can be exploited/extended for the purposes of designing/building Autonomic Networks and Services) project aims to develop a generic architecture for designing and building self-managing networks, with focus on IPv6 and evolving IPv6. This paper provides an overview of the main concepts backing autonomics and how they are being applied by EFIPSANS to build a self-managing infrastructure, able dynamically and automatically to adapt to business and operational changes - thereby moving towards the "zero touch operation" concept.

Key Factors for the Adoption of Cloud Technologies by Telco Operators 

Infrastructure and Platform as Service Clouds represent a major step in the evolution of hosting and the way services are published and consumed on the Internet. This paper analyzes the main aspects of the evolution of Clouds along three major development axes. The first axis has to do with the utility-like provision of ICT infrastructures. Here Clouds have still to evolve in order to achieve the desired level of abstraction as well as a convergent and flexible allocation of the computing, storage, networking and communication resources needed to comply with agreed SLAs. The second axis has to do with support from the marketplace and mashup, or hybrid, functions which will drive transformation of Clouds into true business ecosystems. The third axis addresses the gradual incorporation of built-in programming libraries that will ease development of applications deployed on the Cloud. This paper will also elaborate on existing technologies and the role standards and open source may play in evolution along each of these three axes. Last but not least, opportunities for telco operators in the Cloud Market will be analysed as they could have an advantageous position to offer integrated ICT solutions. Download

Trends in Natural Language Processing and Text Mining

Communication, information, opinions and even feelings are shared, stored and encoded by humans and by their institutions in natural language (as opposed to the artificial, programming or structured languages used by computers). As linguists have experienced for centuries, the analysis and decoding of human language is a complex process, due to its pervasive, low precision, contextual and ambiguous nature. The generalized use of computers and global networks of communication have caused most of our natural language exchanges (email, IM, reports, documentation and even personal ideas, hobbies or stories) to be encoded and stored in digital format and shared through computer systems. Natural Language Processing (NLP) techniques, developed in the field of computational linguistics, are certainly taking advantage of this fact, and are already being widely used in areas such as text mining, information retrieval, document clustering, opinion mining or knowledge management. In this article we take a closer look at external knowledge resources that are just now starting to be exploited to enhance and enrich NLP processes. We also analyze emerging uses of NLP procedures that combine the internal knowledge extracted from documents with the external or background information available to us, through specialized and structured data banks or semantic and conceptual dictionaries.

Security 2.0: Facing up to the Tsunami

We live in times of constant technological progress in which new paradigms and technologies, such as the "Internet of Things", "Semantic Web" or "Cloud Computing" are constantly appearing and promising to make our lives easier. However, the same security problems as always (theft of personal data, denial of service attacks, industrial espionage…) continue to concern us, even more so due to our growing dependence on information technologies. Faced with such a shifting scenario, we need to adopt a strategy with a global approach to confront the ever-present security threats. We believe that this approach should be based on three axes: a) security of infrastructures; b) security based on collaboration between parties; c) security of the individuals, focusing on digital identity and ensuring its privacy. In this article we describe our vision of how we can withstand the tsunami of security problems. Download

Trust in the Information Society: RISEPTIS Report

The report issued in October 2009 by RISEPTIS (Research and Innovation in Security, Privacy and Trustworthiness in the Information Society), the Advisory Board of the European Union Think-Trust Project, is offered on these pages in abridged form. The report addresses highly important issues (privacy, security, trust…), founded on the key principle that a European Information Society should comply with the longstanding social principles that have served Europe so well to date, because democratic values and institutions, freedom and the respect of privacy are essential for trust in our society. So too is law enforcement, accountability and transparency. The social trust thus created is essential. Download
