Duration: January 2017 - December 2019
Keywords: 5G; Small Cells; Elastic Optical Networks; SDN/NFV

Description: The fifth-generation of mobile network (5G) is envisioned to enable the so-called networked society of the future, where both user and machine-type communications will share access to information anywhere and anytime to anyone and anything. Although the details of 5G are still under discussion, it is nevertheless accepted that 5G must offer ubiquitous ultra- broadband connectivity with 1000x aggregated capacity (bit/s/area) with respect to 4G and individual rates ranging from 100 Mb/s (minimum guaranteed) up to 10 Gb/s, and latency below 1ms (compared with 4G's current 15ms requirement) and seamless service delivery to a larger number of subscribers and connected devices and things, on attempts to realise a whole new generation of services such as augmented reality, high-definition video streaming and conferencing, machine inter-connectivity (M2M) and data collection for the Internet of Things and Smart Cities and ultra-low latency applications such as driverless cars. Realising a high-performance optical backhaul network for 5G transport in a cost-effective manner requires to re-think and re-engineer and re-architect many of its components, some of which will be targeted by TEXEO’s objectives. Taking as a starting point an extreme scenario featuring: C-RAN architecture support, massive small cell deployment (ultra- densification) and massive use of 10Gb/s of radio technologies, TEXEO will address both the muscle and the intelligence of the network. That is, building a faster data-plane capable of moving ultra-broadband capacity from one side of the network to another, combined with a flexible, programmable, vendor-independent control plane capable of setting resources were needed, in a cost-efficient way, and with extra mobility aspects. TEXEO will investigate a number of technology enablers of 5G, including the benefits of elastic optical networks in terms of bandwidth capacity and cost savings, the integration of fixed and mobile services through the metro and the access, where residential users can coexist with small cell deployments on the same xPON, the orchestration of network capacity and spectrum slices via Software-Defined Networking for the transport of fronthaul and backhaul flows in a C-RAN scenario; and the challenges faced by 5G to support machine- type communications and other next-generation services. A testbed including radio access components, a TWDM-PON and an SDN controlled metro network shall be developed for experimentation and validation of proposed enhancements.

Project website: click here
Funded by: European Commission, ICT Program FP7, Grant agreement: FP7-ICT-248606
Duration: February 2010 - August 2012

Description:MyUI will foster the mainstreaming of accessible and highly individualized ICT products – a major issue for e-Inclusion. The project addresses important barriers which include developers’ lack of awareness and expertise, time and cost requirements of incorporating accessibility and missing validated approaches and infrastructures. The project’s approach goes beyond the notion of Universal Design by addressing specific user needs through adaptive personalized interfaces. An ontology-based context management infrastructure will collect user  and context information in real-time during use. Sharing the collected information across several personal applications will increase efficiency and validity. The user interface will self-adapt to the evolving individual user model, in order to fit the user’s special needs and preferences. The MyUI adaptation engine will rely on empirically based design patterns for specified user and context characteristics.

Providing support for developers is a key goal of the project. Accessibility guidelines, re-usable interface components and a virtual environment for illustration, training and monitoring will support the mainstreaming of accessibility in ICT products. An interface adaptation engine and simulation tools will help developers test, assess and refine their designs. MyUI technologies will be implemented in three selected ’use cases’ to demonstrate their benefit and feasibility in industrial development contexts: interactive TV device, interactivedigital physiotherapy service, and interactive socialization service.

Description: The core activity of the BONE-project is the stimulation of intensified collaboration, exchange of researchers and integration of activities and know-how into and amongst partners. Through the establishment of Virtual Centres of Excellence, the BONE-project looks into the future and builds and supports the final “Network of the Future” through education and training, research tools & testlabs on new technologies & architectures. The leading-edge position of European Research in the field and, consequently, of European industry, could be threatened by returning to an uncoordinated and scattered approach to optical networking research. BONE consolidates the process, supported during FP6, of integration and reorganization of research efforts across European academic and industrial groups in FP7 through:

  • Building Virtual Centres of Excellence that cover specific issues in the field of Optical Networking that can serve to European industry with education & training, research tools & testlabs and pave the way to development of new technologies & architectures.
  • Reaching out, including and linking to research activities in national programmes, or programmes outside Europe.
  • Stimulating an intensified collaboration, exchange of researchers between the research groups involved and active in the field.
  • Disseminating the expertise and know-how of these European Research groups to a broader audience, both R&D oriented as well as industry- and decision maker oriented.


Future Internet: Eficiencia en las Redes de Altas Prestaciones

Descripción: FIERRO es una Red Temática que agrupa a 21 Universidades, Centros de Investigación y empresas españolas, que investigan en los retos tecnológicos que la Internet del Futuro (Future Internet) plantea en la red IP de altas prestaciones. Con esto nos referimos a las redes de comunicaciones de alta velocidad, por ejemplo con agregados de tráfico de 10 Gbps en adelante. Los retos de investigación abordados aparecen en todas las capas de red, y están relacionados principalmente con tres problemas de escala asociados al crecimiento de la Internet del Futuro:

  • Escalado en volumen de tráfico. La popularización masiva de enlaces de acceso a red desde el usuario final en el orden de 1 Gbps, implica un salto proporcional en el volumen de tráfico que las redes de agregación de altas prestaciones deben soportar. Como ejemplo en el plazo más corto, la introducción masiva de FTTH (Fiber To The Home) implica unos accesos de 50-100 Mbps por usuario en el canal descendente, que es alrededor de un orden de magnitud mayor al acceso estándar más popularizado. La experiencia dicta que cuando ese ancho de banda se ofrece al usuario final, el usuario lo usa.
  • Escalado en granularidad de tráfico. La convergencia de servicio multimedia sobre IP en la Internet del Futuro es asumida como un hecho. Esto implica una explosión en el número de flujos sujetos a restricciones de QoS. Los servicios IPTV dentro de los paquetes Triple-Play se consideran las killer-applications en este entorno.
  • Escalado en la variabilidad del tráfico y la movilidad. El acceso a través de redes celulares, implica que fuentes móviles pueden ser generadoras de flujos del orden de Mbps/Gbps. En las redes IP de altas prestaciones donde el tráfico es agregado, la movilidad de flujos de ancho de banda relevante redunda en una mayor variabilidad del tráfico.
  • Estos tres incrementos de escala, amenazan con ser la fuente de una gran ineficiencia en las redes IP de altas prestaciones, si no se aplican técnicas específicas para ello. En este contexto, la eficiencia no es un valor añadido, sino una necesidad para que la Internet del Futuro sea posible.

Description: e-Photon/ONE Network of Excellence (NoE) aims at integrating and focusing the rich know-how available in Europe on optical communication and networks, both in universities and in research centres of major telecom manufacturers and operators. The set of available expertise ranges from optical technologies, networking devices and network architectures and protocols, to the new services fostered by photonic technologies. The NoE will contribute to the Strategic Objective “Broadband for All”, with a particular focus (quoting from the EC IST 2003-2004 Workprogramme, page 15) on “low cost access equipment”, “new concepts for network management, control and protocols”, and “increasing bandwidth capacity in the access network as well in the underlying optical core/metro network (including in particular optical burst and packet switching)”. The main technical focus of the NoE is to demonstrate the potential advantages of optical technologies in telecommunication networks with respect to electronic technologies. Strong cooperation among the participants to the NoE will favour a consensus on the engineering choices towards the deployment of cost-effective optical technologies in networking. This will support the future Internet, providing inputs to the standardization bodies and guidelines to the operators, as well as competitive advantages to European telecom equipment manufacturers. Integration will be pursued primarily by establishing long-term collaborations among partners in terms of research, infrastructures sharing, and education and training. The main instruments used to achieve these long-lasting collaborations are the regular exchange of researchers between partners, and the development of joint teaching programs. Dissemination will be pursued by means of coordinated publication activities, offering training programs, the organization of technical events, and interactions with other consortia in the same technical area. Research activities will mainly be carried out in research programs external to the NoE, both at the national and at the European level. Well focused technical research programs will be activated internally to the NoE.

Description: Improvisa is a project of the "Tecnologías de Servicios de la sociedad de la Información (TSI) convocatoria 2005" program from MEC, carried out by Universidad Politécnica de Madrid (TSI2005-07384-C03-01), Universidad Carlos III de Madrid (TSI2005-07384-C03-02) and Universidad de Alcalá (TSI2005-07384-C03-03). IMPROVISA addresses the issue of real service provisioning in scenarios lacking a fixed communications infrastructure, where the cooperation between humans and electronic devices (computers, sensors/actors, robots, intelligent nodes, etc) is paramount. An example of this sort of scenario is emergency management in natural catastrophes. Technological solutions to this problem can be found in the field of ad-hoc networking. Mobile Ad-hoc Networks (MANETs) are made up of a set of heterogeneous, autonomous and self-organising mobile nodes interconnected through wireless technologies. To date, most of the research in MANETs has focused on the design of scalable routing protocols. This project is focused on the development of real concrete application-oriented architectures, by the synergic integration of technologies covering practical ad-hoc networking, security frameworks, improved multimedia delivery, service-oriented computing and intelligent agent platforms that enable the deployment of context-aware networked information systems and decision support tools in the target scenario.
