    In this paper, I will develop two major claims. First the, Future Internet should be polymorphic and conciliate different architectural paradigms networking. The second claim is that the Future Internet should be build on strong theoretical basis from a Networking science that is in course of development. In this paper, I have used the concept of cooperation as an interpretation lens. Specifically, I will describe how virtualisation make possible a polymorphic future Internet and enables the easy deployment of new cooperation schemes. The next aspect that I describe in this paper is relative to security in the future Internet. Particularly the paper advocates the necessity of three major components: a secure execution platform, an authentication mechanism, and a monitoring component. Finally, I will show that it is possible to build scalable addressing and routing scheme but at the condition of following a clean slate approach. View full abstract»

    There is growing recognition that we are rapidly approaching the physical capacity limit of standard optical fiber. It is important to make better use of optical network resources to accommodate the ever-increasing traffic demand to support the future Internet and services. We first introduce an architecture, enabling technologies, and the benefits of recently proposed spectrum-efficient and scalable elastic optical path networks. In these networks, the required minimum spectral resources are adaptively allocated to an optical path based on traffic demand and network conditions. We then present possible adoption scenarios from current rigid optical networks to elastic optical path networks. We also discuss some possible study items that are relevant to the future activities of ITU-T. These items include optical transport network (OTN) architecture, structure and mapping of the optical transport unit, automatically switched optical network (ASON) control plane issues, and some physical aspects with possible extension of the current frequency grid.

    The present day Internet has no separate namespace for host IDs. It uses IP addresses as host IDs, which are in fact locators. This dual role is problematic for mobility, multihoming, security, and routing on the Internet. To solve these problems, research has recently begun on ID/locator split architectures. Some standardization activities based on this concept are also progressing in ITU-T Study Group 13 and in the IETF. We expect that introduction of the ID/locator split concept into the new generation network or future Internet architecture can bring about additional functions, such as heterogeneous network protocol support, multicast, QoS, resource or service discovery, and flexible human-network interaction. Toward realization of these functions, this paper presents a study on an approach of introducing multi-ID and multi-locator support into the network architecture. The paper also lists items that have the potential to be standardized in ITU-T. View full abstract»

    As delivering contents has become the dominant usage of Internet, the efficient content distribution is being one of the hottest research areas in network community. In future network, it is anticipated that network entities such as routers will be equipped with in-network storage due to the trend of ever-decreasing storage cost. In this paper, we propose a novel content delivery architecture called Internet Service Provider (ISP) centric Content Delivery (iCODE) by which an ISP can provide content delivery services as well. iCODE can provide efficient content delivery services since an ISP can cache the contents in routers with storage modules considering traffic engineering and the locality of the content requests. Compared with CDN and P2P systems, iCODE can offer reduced delivery latency by placing the contents closer to end hosts, and incentives to ISPs by reducing inter-ISP traffic and allowing traffic engineering. We also discuss the technical and business issues to realize the iCODE architecture. View full abstract»

    Maths is presently regarded as the key driver that underpins Science, Education and Technology (SET) skills. In spite of significant studies, investment and efforts, math skills and widespread enthusiasm for SET remain elusive. In South Africa's disadvantaged communities, poor quality maths teaching and poor maths performance, both legacies of past political engineering, further fuel marginalization. Computational thinking is a new characterization of some specific procedural thinking, abstraction, problem solving and organizational skills that are finding their way from computer science programs into other fields. The paper describes our refocus of content in BingBee, a SET skill-building kiosk project targeting disadvantaged communities. As we shift to emphasize computational thinking more explicitly, we speculate that these skills could complement, and perhaps eventually displace, some elements of maths as the dominant driver of SET. The confluence of better tools, open service interfaces, and the rapid spread of handsets and devices into marginalized communities is an opportunity to build more widespread computational thinking skills. This could in turn facilitate a future Internet which is more inclusive, and in which users are able to create their own services. View full abstract»

  • Challenges the Internet poses to the policymaker

    This paper addresses policymakers at national and international levels - regulators, standards bodies, politicians - arguing that there is no “beyond” the Internet. With the Internet so intimately intertwined with the lives of people, being used to build the backbone of large, important communities, an attempt to replace it with a new network would generate immense friction, and cost a lot. The transition would take long, because lots of complex software would need to be written, disrupting critical processes of the economy, indeed of governance. A plethora of regulators with very different manners and degrees of control would have to learn to work together at an international level, otherwise we might revert to the lawlessness of the Internet. The lost opportunity of Minitel, the botched attempt to look beyond the Internet in the 1990s via X.400 and the bankruptcy of large telecommunication companies in the wake of the dotcom boom are useful in appreciating the historical context and learning lessons from. Instead of looking beyond, the ITU should play a constructive role vis-à-vis the Internet. Suggestions presented are elimination of spam, and making the Internet accessible to all. These make commercial sense too. View full abstract»

    This work illustrates the methodological approach followed in the Province of Orellana, Eastern Ecuador, for the realization of a telecommunication network infrastructure between the capital of the Province, the city of Puerto Francisco de Orellana (also known as El Coca), and some peripheral communities located in the surrounding of the tropical moist forest. The project has been implemented in one of the poorest countries of Latin America, in a remote and disadvantaged area where the lack of communication infrastructures and the absence of almost all public services generates a strong migration towards the capital. In this context, in 2008, it was conceived a project for the development of a communication system that allows the provisioning of basic intranet services for distance learning, telemedicine and internet connectivity. The main scope of the project was the development of an approach focused on the technological transfer to the local population, to start a reduction process of the digital gap in the area. The aim of the project has been achieved thanks to the direct enrolment of local municipalities, small entrepreneurs, communities and local NGO. The technological transfer to local players and the choice of a suitable platform, designed for a simplified, low cost management, guarantee the sustainability and scalability of the project. The declaration of interest in the infrastructure by the Municipality enables the economic sustainability of the project. View full abstract»

    The government of Japan has announced the new ICT policy in June 2010. One of the points of the new policy is to start the 3D motion image content market in order to create new key industries in the near future as 3D motion image content will become most powerful media for CGM (Consumer Generated Media). In order to activate 3D motion image content industries, the development of an effective and simple tool for making 3D motion image content even by non-experienced people, is required. The Digital Movie Director (DMD) developed by the author, is being evolved as such an effective and simple tool. However, the big computational power requirement in making 3D motion image content has prevented DMD from being widely deployed. The cloud computing technology is supposed to solve this problem, thus, in this paper, the future prospects of the 3D motion image content industries with the cloud computing technology will be explained.

    In this paper, we consider hybrid circuit/packet networks. A hybrid circuit/packet network consists of a circuit network co-existing with a packet network; generally the packet network is embedded on top of the circuit network. However, in certain cases such as the DOE energy sciences network (ESnet), the circuit network and the packet network are deployed side-by-side (e.g. they have common end-node sites and equipment), but they are logically separate and they may have physically disjoint links. Currently, there is no capacity sharing between the packet and the circuit sections of the networks. In this paper, we propose and investigate the characteristics of schemes that enable efficient capacity partitioning between packet and circuit networks while ensuring survivability and robustness of the services. We conduct simulative experiments on ESnet topology with realistic traffic demands. We observe that capacity partitioning between packet and circuit networks enables to support services with enhanced quality of service and robustness along with improved resource utilization.

    Evolution of the Internet user has brought attention to the lack of standards for ideal levels of user interaction. The core Internet architecture has not evolved much since its inception, and its user-driven limitations typically constrain one's personal computing infrastructure so that the goals of pervasive and ubiquitous computing are only incipiently achieved. We propose to consider the user's image, or user space, as a significant entity in the Internet model by introducing a new layer of protocols into the Internet protocol stack to support future usage in the Internet. We also present the Identifier/Interlocutor/Locator split architecture for flexible addressing. Standards for such architectures would provide generic user support across heterogeneous networks.

    Whatever the Network of the Future turns out to be, there is little doubt that QoS will constitute a fundamental requirement. However, QoS issues and the respective solutions will not remain unchanged. New challenges will be raised; new ways of dealing with QoS will be enabled by novel networking concepts and techniques. Thus, a fresh approach at the QoS problem will be required. This paper addresses QoS in a Future Internet scenario and is focused on three emerging concepts: Network Virtualization, enabling the coexistence of multiple network architectures over a common infrastructure; In-Network Management, improving scalability of management operations by distributing management logic across all nodes; the Generic Path based on the semantic resource management concept, enabling the design of new data transport mechanisms and supporting different types of communications in highly mobile and dynamic network scenarios.

    With the advent of the Internet, search engines were developed for English language because English language was a lingua franca. Currently, most of popular search engines such as Google and Yahoo! are available in more than 50 languages. However, these search engines have received less attention in South Asian languages especially, Urdu language. In this paper, we propose a novel approach for feature extraction and classification of queries in cross-language search engines. This novel approach presents an automatic method for classification of English and Urdu languages identification. The classifier used is a three-layered feedforward artificial neural network and the feature vector is formed by calculating the wavelet coefficients. Three wavelet decomposition functions (filters), namely Haar, Bior 2.2 and Bior 3.1 have been used to extract the feature vector set and their performance results have been compared. The performance results of the Haar filter have given superior results than other filters. View full abstract»

    Geographic location and Grid computing are two areas that have taken off in recent years, both receiving a lot of attention from research community. The Grid Resource Brokers, which tries to find the best match between the job requirements and the resources available on the Grid, can take benefits by knowing the geographic location of clients, for a considerable improvement of their decision-taking functions. A measurement-based geolocation service estimates host locations from delay measurements taken from landmarks, which are hosts with a known geographic location, toward the host to be located. Nevertheless, active measurement can burden the network. Relying on database-driven geolocation and active measurements, we propose GeoHybrid. GeoHybrid estimates the geographic location of Internet hosts with low overhead as well better accuracy with respect to geolocation databases. Afterwards, we propose a geolocation middleware for grid computing. By defining the architecture and the methods of this service, we show that a promising symbiosis may be envisaged by the use of the proposed middleware service for grid computing.

    This work describes innovative smart environments with embedded context-awareness technologies, enabling new business models and consequently the creation of new services. The context-awareness framework presented in this paper is taken from the results of an EU Framework Programme (FP) 7 Information and Communications Technologies (ICT) project. Major novelties include a business shift from traditional and conventional telecommunication or ICT services towards highly personalized, customized and user targeted services, empowered by a myriad of pervasive and ubiquitous interconnected environments employing various kinds of context information. In this work, we show how these context data can be technically made available as a service and business enabler and be used by any entity or application built within these environments, using context for adapting service logic or for targeted service customization. Moreover, it considers customer's needs and privacy aspects, providing users with a more immersive and less intrusive experience at the same time. View full abstract»

    While modern telecommunications are becoming ever more useful and even necessary in everyday life, not all groups of people are equally capable of using them. Due to inevitable demographic changes the elderly are growing in number, yet they are not very well served by user interfaces for the various telecommunications tools. The prime target group for our proposed technology is people with cognitive and motor disabilities, whether due to age, illness or traumatic events. They require a user interface which enables them to make or redirect calls, create conferences, set forwarding and/or access different voice XML services - without the complexity of keyboards or menus with tree structures. The motivators behind this are: simplicity, accessibility, usability and efficiency - all within the scope of potential user groups and usage scenarios. The key enablers are Next Generation Network (NGN) open interfaces and Near Field Communication (NFC) technology as a part of Radio Frequency Identification (RFID) family. View full abstract»

    An empirical study which identifies 251 technical interoperability standards implemented in a modern laptop computer, and estimates that the total number of standards relevant to such a device is much higher. Of the identified standards, the authors find that 44% were developed by consortia, 36% by formal standards development organizations, and 20% by single companies. The intellectual property rights policies associated with 197 of the standards are assessed: 75% were developed under “RAND” terms, 22% under “royalty free” terms, and 3% utilize a patent pool. The authors make certain observations based on their findings, and identify promising areas for future research. View full abstract»

    The evolution of current networks to Next Generation Networks (NGNs) constitutes arguably the most significant transformation in the Telecommunication sector in recent decades. Quality of Service (QoS) is one of the key aspects in this evolution. In the NGN environment, networks are designed to be multi-service, supporting a wide range of premium services. Each of these services may have different QoS requirements which should be established based on the overall end users' perception. In this emerging context, novel QoS policies are required to adapt the traditional QoS regulatory model to the new scenario. This paper presents a user-centric approach to identify key factors that contributes to the development of quality of service regulation in future networks. A case study on the application of our user-centric QoS model to the Internet QoS regulation in Spain is described. The results of the study demonstrate the need for adapting current regulatory frameworks in order to ensure competition, pluralism and diversity in the new network environment. View full abstract»

    Standards formation is a key dimension in the competitive strategy of ICT firms, as a successful strategy would result in the emergence of favorable IT interoperability standards. This paper examines the standardization efforts of core Web services standards and the results indicate that resource dependencies and strategies adopted by dominant firms to extend their platforms influence the standards formation process. Communities of practice and standard-setting bodies are leveraged by dominant firms in the formation and adoption of standards. We propose a process model of standard setting consisting of five intertwined states: resource pooling, linkages, signaling and implementation, institutionalization, and extension.
