Multidomain Network Based on Programmable Networks: Security Architecture
No full textThis paper proposes a generic security architecture
designed for a multidomain and multiservice network
based on programmable networks. The multiservice
network allows users of an IP network to run
programmable services using programmable nodes
located in the architecture of the network. The
programmable nodes execute codes to process active
packets, which can carry user data and control
information. The multiservice network model defined
here considers the more pragmatic trends in
programmable networks. In this scenario, new security
risks that do not appear in traditional IP networks become
visible. These new risks are as a result of the execution of
code in the programmable nodes and the processing of the
active packets. The proposed security architecture is based
on symmetric cryptography in the critical process,
combined with an efficient manner of distributing the
symmetric keys. Another important contribution has been
to scale the security architecture to a multidomain
scenario in a single and efficient way.Publicad
Operationalizing the “atrocity prevention lens”: making prevention a living reality
No full textIn his closing remarks to the 2012 informal interactive dialogue of the United Nations General Assembly on the Responsibility to Protect (R2P), UN Deputy Secretary-General, Jan Eliasson called for the prevention of genocide and mass atrocities to be made a “living reality.” Three years earlier, in his first report on implementing R2P, the Secretary-General had described “the ultimate purpose of the responsibility to protect” as being “to save lives by preventing the most egregious mass violations of human rights.” Indeed, since the adoption of R2P at the 2005 World Summit, there have been many generic calls for a focus on the prevention of genocide, war crimes, ethnic cleansing, and crimes against humanity (hereafter genocide and mass atrocities). This is unsurprising, given that the world’s commitment to R2P included a specific call for the prevention of these crimes. Since 2009, UN Member States of all types and from every region have voiced their support in the General Assembly for the prevention of genocide and mass atrocities, recognizing that it not only saves lives but also reduces the need for enforcement further down the line. This sentiment echoes views expressed in the academy, which largely agrees that prevention is far better than cure. But although there is broad agreement about the normative and practical imperative of preventing genocide and mass atrocities, much less is understood about how this might be achieved in practice. Although work examining the incorporation of genocide and mass atrocity prevention into US foreign and defense policy has progressed apace, relatively little attention has been paid to the question of how to implement the preventive aspects of R2P more generally and less still to the specific role played by pivotal international organizations such as the UN. To date, academic work on the UN's role has tended to focus, understandably, on early warning and assessment, although an emerging body of work examines the role of the system's human rights mechanisms in helping to prevent genocide and mass atrocities. Thus far, the UN itself has focused on developing its mandate and capacity for early warning and assessment, as well as on the establishment of a convening authority designed to facilitate timely advice in crisis situations. The UN has also begun preliminary work, under the auspices of the Framework Team's Experts Reference Group on Prevention, on system-wide approaches to genocide and mass atrocity prevention
The Future Internet - Future Internet Assembly 2013: Validated Results and New Horizons
No full textThe Internet is the most vital scientific, technical, economic and societal set of infrastructures in existence and in operation today serving 2.5 billion users. Continuing its developments would secure much of the upcoming innovation and prosperity and it would underpin the sustainable growth in economic values and volumes needed in the future. Future Internet infrastructures research is therefore a must.
The Future Internet Assembly (FIA) is a successful conference that brings together participants of over 150 research projects from several distinct yet interrelated areas in the European Union Framework Programme 7 (FP7). The research projects are grouped as follows: the network of the future as infrastructure connecting and orchestrating the future Internet of people, computers, devices, content, clouds and things; cloud computing, Internet of Services and advanced software engineering; the public-private partnership projects on Future Internet; Future Internet Research and Experimentation (FIRE).
The 26 full papers included in this volume were selected from 45 submissions. They are organized in topical sections named: software driven networks, virtualization, programmability and autonomic management; computing and networking clouds; internet of things; and enabling technologies and economic incentives

Towards a Socially-Aware Management of New Overlay Application Traffic Combined with Energy Efficiency in the Internet (SmartenIT)
No full textThe Internet has seen a strong move to support overlay applications, which demand a coherent and integrated control in underlying heterogeneous networks in a scalable, resilient, and energy-efficient manner. A tighter integration of network management and overlay service functionality can lead to crosslayer optimization of operations and management, which is a promising approach as it offers a large business potential in operational perspectives for all players involved. Therefore, the objective of this paper is to present SmartenIT (Socially-aware Management of New Overlay Application Traffic combined with Energy Efficiency in the Internet), which targets at an incentivecompatible cross-layer network management for providers of overlay-based application (e.g., cloud applications, content delivery, and social networks), network providers, and end-users. The goal is to ensure a QoE-awareness, by addressing accordingly load and traffic patterns or special application requirements, and exploiting at the same time social awareness (in terms of user relations and interests). Moreover, energy efficiency with respect to both end-user devices and underlying networking infrastructure is tackled to ensure an operationally efficient management. Incentive-compatible network management mechanisms for improving metrics on an inter-domain basis for ISPs serve as the major mechanism to deal with and investigate real-life scenarios
Design and Implementation of Cooperative Network Connectivity Proxy Using Universal Plug and Play
No full textReducing the network energy waste is one of the key challenges of the Future Internet. Many Internet-based applications require preserving network connectivity for getting incoming remote service requests or confirming their availability and presence to remote peers by sending periodic keep-alive or heart-beating messages. Billions of dollars of electricity is wasted every year to keep idle or unused network hosts fully powered-up only to maintain the network connectivity. This paper describes a new approach to design and implement the cooperative Network Connectivity Proxy (NCP) for reducing energy waste in the ever-growing future Internet. The NCP is implemented using Universal Plug and Play (UPnP), that uses a set of protocols to allow seamless discovery and interaction between the network hosts and the NCP. The NCP allows all registered network hosts to transition into the low power sleep modes and maintains the network connectivity on their behalf. It handles basic network presence and management protocols like ICMP, DHCP, ARP etc on behalf of the sleeping network hosts and wakes them up only when their resources are required. Depending on the network hosts time usage model, the NCP can provide about 60 to 70% network energy savings
High availability in the future internet
No full textWith the evolution of the Internet, a huge number of real-
time applications, like Voice over IP, has started to use IP as primary
transmission medium. These services require high availability, which is not
amongst the main features of today’s heterogeneous Internet where fail-
ures occur frequently. Unfortunately, the primary fast resilience scheme
implemented in IP routers, Loop-Free Alternates (LFA), usually does not
provide full protection against failures. Consequently, there has been a
growing interest in LFA-based network optimization methods, aimed at
tuning some aspect of the underlying IP topology to maximize the ratio
of failure cases covered by LFA. The main goal of this chapter is to give a
comprehensive overview of LFA and survey the related LFA network op-
timization methods, pointing out that these optimization tools can turn
LFA into an easy-to-deploy yet highly effective IP fast resilience scheme
