  • Planning of dynamic virtual optical cloud infrastructures: The GEYSERS
           approach
    • Authors: Tzanakaki; A.;Anastasopoulos, M.;Georgakilas, K.;Landi, G.;Bernini, G.;Ciulli, N.;Riera, J.F.;Escalona, E.;Garcia-Espin, J.A.;Hesselbach, X.;Figuerola, S.;Peng, S.;Nejabati, R.;Simeonidou, D.;Parniewicz, D.;Belter, B.;Martinez, J.R.;
      Pages: 26 - 34
      Abstract: This article focuses on planning and replanning of virtual infrastructures over optical cloud infrastructures comprising integrated optical network and IT resources. This concept has been developed in the context of the European project GEYSERS. GEYSERS has proposed a novel multi-layer architecture, described in detail, that employs optical networking capable of provisioning optical network and IT resources for end-to-end cloud service delivery. The procedures required to perform virtual infrastructure planning and replanning at the different architecture layers are also detailed. An optimization scheme suitable to dynamically plan and replan virtual infrastructures is presented and compared to conventional approaches, and the benefits of dynamic replanning are discussed and quantified. The final project demonstration, focusing on planning, replanning, and dynamically establishing virtual infrastructures over the physical resources, is presented, while some emulation results are provided to further evaluate the performance of the GEYSERS solution.

  • Flexible packet-optical integration in the cloud age: Challenges and
           opportunities for network delayering
    • Authors: Sabella; R.;Testa, F.;Iovanna, P.;Bottari, G.;
      Pages: 35 - 43
      Abstract: The telecommunication community has reached a broad consensus on the vision that future transport architecture will be dominated by optical in combination with IP. This implies a complete reassignment of the functions traditionally handled by legacy intermediate layers to packet and optical layers only. Here, current advances in photonic technologies and architectures enable the optical layer to become the ideal companion of the packet world and to unlock an effective packet offload toward flexible and dynamic optical pipes. A global crosslayer optimization is needed to minimize the misalignment between cost and revenues, and manage the rising tide of IP traffic. In this article, we describe this evolving path and explore the impact on network planning and traffic provisioning, also considering implications on the cloud scenario and sighting the software defined networks horizon.

  • Multi-layer capacity planning for IP-optical networks
    • Authors: Gerstel; O.;Filsfils, C.;Telkamp, T.;Gunkel, M.;Horneffer, M.;Lopez, V.;Mayoral, A.;
      Pages: 44 - 51
      Abstract: We consider a pragmatic multi-layer capacity planning approach for an IP over optical network, which builds on existing planning practices. We first describe a router bypass process that considers the real impact of the IP layer topology change, given the actual behavior of the IP layer, leveraging a commercial IP planning tool. We then consider the design and cost impact of several multi-layer restoration schemes. We compute the savings achieved on two real-world core network models. The resulting savings are similar for both networks and are very promising.

  • In-operation network planning
    • Authors: Velasco; L.;Castro, A.;King, D.;Gerstel, O.;Casellas, R.;Lopez, V.;
      Pages: 52 - 60
      Abstract: Current transport networks are statically configured and managed, because they experience a rather limited traffic dynamicity. As a result, long planning cycles are used to upgrade the network and prepare it for the next planning period. Aimed at guaranteeing that the network can support the forecast traffic and deal with failure scenarios, spare capacity is usually installed, thus increasing network expenditures. Moreover, results from network capacity planning are manually deployed in the network, which limits the network agility. In this article, we propose a control and management architecture to allow the network to be dynamically operated. Employing those dynamicity capabilities, the network can be reconfigured and reoptimized in response to traffic changes in an automatic fashion; hence, the resource overprovisioning can be minimized and overall network costs reduced.

  • Planning and operating flexible optical networks: Algorithmic issues and
           tools
    • Authors: Kretsis; A.;Christodoulopoulos, K.;Kokkinos, P.;Varvarigos, E.;
      Pages: 61 - 69
      Abstract: We discuss the basic algorithmic issues in planning and operating flexible optical networks, highlighting the challenges and differences from fixed-grid WDM networks. We also overview commercially available planning and operation tools, which (expectedly) lack support for flexible optical networks at the moment, as flexible technologies are not yet deployed in real networks. To fill this need we present the Mantis tool. Mantis' modular architecture provides fast running times, efficient and fault-tolerant usage of computation resources, and execution as both a desktop application and a cloud software-as-a-service.

  • Planning fixed to flexgrid gradual migration: drivers and open issues
    • Authors: Ruiz; M.;Velasco, L.;Lord, A.;Fonseca, D.;Pioro, M.;Wessaly, R.;Fernandez-Palacios, J.P.;
      Pages: 70 - 76
      Abstract: Flexgrid technology has recently been presented as the most promising option for upgrading the currently operating fixed grid optical networks and extending their capacity to be able to deal with the massive traffic volumes forecast for the next decade. Although the current traffic is successfully supported on fixed grid networks, flexgrid technology brings features that are not offered by the fixed grid networks, such as transporting optical connections with a capacity beyond 100 Gb/s and elasticity against time-varying traffic. In light of this, a gradual fixed grid to flexgrid migration is generally accepted in order to add these useful features to the network. In this article, we study the migration process where flexgrid is deployed in the network progressively, and review the main drivers and open issues induced by its deployment.

  • Advanced dynamic migration planning toward FTTH
    • Authors: Reyes; R.R.;Zhao, R.;Machuca, C.M.;
      Pages: 77 - 83
      Abstract: This article proposes a dynamic migration planning methodology for communication networks. Aimed at providing optimal technical performance, the approach takes into account dimensioning of network infrastructure and services, as well as evaluation of revenues and costs. As a result, the migration planning method provides a cost-effective network deployment plan based on an optimal stepwise upgrade strategy. Market information, existing infrastructure, costs, and demand forecasting are then considered in order to determine this strategy by solving a combinatorial optimization problem. It is described theoretically, and a techno-economic evaluation framework is introduced to assess its financial feasibility. The model is a suitable guideline to tackle migration problems commonly solved by using anticipated, single- ,and multi-period planning techniques. Considering a particular example, a study on migration toward fiber to the home is analyzed. Fiber to the cabinet/building architectures are then proposed as possible intermediate steps in the migration path to fiber to the home. Finally, a case study for an existing access network is analyzed.

  • Mobile ad hoc networking: milestones, challenges, and new research
           directions
    • Authors: Conti; M.;Giordano, S.;
      Pages: 85 - 96
      Abstract: In this article we discuss the state of the art of (mobile) multihop ad hoc networking. This paradigm has often been identified with the solutions developed inside the IETF MANET working group, and for this reason it is called the MANET paradigm. However, they do not coincide, and in the last decade they clearly diverged. In this article, we start from the reasons why the MANET paradigm did not have a major impact on computer communications, and we discuss the evolution of the multihop ad hoc networking paradigm by building on the lessons learned from the MANET research. Specifically, we analyze four successful networking paradigms, mesh, sensor, opportunistic, and vehicular networks, that emerged from the MANET world as a more pragmatic application of the multihop ad hoc networking paradigm. We also present the new research directions in the multihop ad hoc networking field: peoplecentric networking, triggered by the increasing penetration of the smartphones in everyday life, which is generating a people-centric revolution in computing and communications.

  • From "smart objects" to "social objects": The next evolutionary step of
           the internet of things
    • Authors: Atzori; L.;Iera, A.;Morabito, G.;
      Pages: 97 - 105
      Abstract: Social networking concepts have been applied to several communication network settings, which span from delay-tolerant to peer-to-peer networks. More recently, one can observe a flourish of proposals aimed at giving social-like capabilities to the objects in the Internet of Things. Such proposals address the design of conceptual (and software) platforms, which can be exploited to easily develop and implement complex applications that require direct interactions among objects. The major goal is to build techniques that allow the network to enhance the level of trust between objects that are "friends" with each other. Furthermore, a social paradigm could definitely guarantee network navigability even if the number of nodes becomes orders of magnitude higher than in the traditional Internet. Objectives of this article are to analyze the major opportunities arising from the integration of social networking concepts into the Internet of Things, present the major ongoing research activities, and point out the most critical technical challenges.

  • Crowd textures as proximity graphs
    • Authors: Martella; C.;Steen, M.V.;Halteren, A.V.;Conrado, C.;Li, J.;
      Pages: 114 - 121
      Abstract: We are only starting to understand how people behave when they are part of a crowd. This article presents a novel approach to the study and management of crowds. The approach comprises a device to be worn by individuals, an infrastructure to collect the information from the devices, a set of algorithms for recognizing crowd dynamics, and a set of feedback strategies to intervene in the crowd. A fundamental element of our approach is to consider crowds in terms of their texture. The crowd texture is represented through the proximity graph, a data structure that captures the spatial closeness relationship between individuals over time. We address its properties and limitations, a system architecture to measure and process it, and a few examples of insights that can be obtained from analyzing it.

  • Scheduling multi-channel and multi-timeslot in time constrained wireless
           sensor networks via simulated annealing and particle swarm optimization
    • Authors: Kim; Y.G.;Lee, M.J.;
      Pages: 122 - 129
      Abstract: Timely communication in wireless multihop sensor networks requires high throughput and low delay, which can be achieved by exploiting multiple channels and time slots. Efficient scheduling becomes indispensable if multiple channels and time slots are utilized. Optimum scheduling of multiple channels and time slots in multihop networks is an NP-complete problem. We apply metaheuristic approaches to solve the scheduling problem because of the fact that not only the global solution but near-optimal solutions can satisfy a given end-to-end delay bound. We adopt simulated annealing (SA) and particle swarm optimization (PSO) to schedule the resources. Different measures and stopping conditions are explored to validate the feasibility of scheduling via SA and PSO, and to compare the performance of the two metaheuristics in satisfying the desired end-to-end delay. Although the purpose of this article is to compare SA and PSO, the simulation results demonstrate that PSO-based scheduling outperforms SA-based scheduling in terms of end-to-end delay.

  • Network and service management [Series Editorial]
    • Authors: Pras; A.;Pavlou, G.;
      Pages: 130 - 131
      Abstract: This is the 16th issue of the series on Network and Service Management, which is typically published twice a year, from 2014 in January and July. In recent years it was published in July and December, but the December 2013 issue moved to January 2014 for "symmetry," with a six-month interval between the two issues in the future. The series provides articles on the latest developments in this well-established discipline, highlighting recent research achievements and providing insight into both theoretical and practical issues related to the evolution of the discipline from different perspectives. The series provides a forum for the publication of both academic and industrial research, addressing the state of the art, theory and practice in network and service management.

  • Challenges to support edge-as-a-service
    • Authors: Davy; S.;Famaey, J.;Serrat, J.;Gorricho, J.L.;Miron, A.;Dramitinos, M.;Neves, P.M.;Latre, S.;Goshen, E.;
      Pages: 132 - 139
      Abstract: A new era in telecommunications is emerging. Virtualized networking functions and resources will offer network operators a way to shift the balance of expenditure from capital to operational, opening up networks to new and innovative services. This article introduces the concept of edge as a service (EaaS), a means of harnessing the flexibility of virtualized network functions and resources to enable network operators to break the tightly coupled relationship they have with their infrastructure and enable more effective ways of generating revenue. To achieve this vision, we envisage a virtualized service access interface that can be used to programmatically alter access network functions and resources available to service providers in an elastic fashion. EaaS has many technically and economically difficult challenges that must be addressed before it can become a reality; the main challenges are summarized in this article.

  • The fluid internet: service-centric management of a virtualized future
           internet
    • Authors: Latre; S.;Famaey, J.;Turck, F.D.;Demeester, P.;
      Pages: 140 - 148
      Abstract: The Internet was originally designed as a best effort packet forwarding substrate. However, since its inception, its purpose has shifted toward a rich service-centric delivery platform. Its underlying infrastructure as well as the number of connected devices have taken on immense proportions, and sharing of capabilities has come into widespread use. Moreover, the Internet??s services are becoming increasingly interactive, context-aware, and content-oriented. This has led to stringent delivery requirements being imposed on the underlying infrastructure. Despite these evolutions, management of the Internet has not evolved significantly. It remains largely static and is unable to provide dynamic end-to-end service delivery guarantees in a costeffective manner. In this article, we propose the Fluid Internet, a novel paradigm aimed at tackling these management challenges. The Fluid Internet seamlessly provisions virtualized infrastructure capabilities, adapting the delivery substrate to the dynamic requirements of services and users, much like a fluid adapting to fit its surroundings. As such, the Fluid Internet gives a service provider the ability to manage its services end to end and elastically. Our vision is achieved through a unification of concepts from network virtualization, cloud computing, and service-centric networking. The relevant stakeholders, as well as their functions and interactions, are described. Additionally, we identify the major technical challenges that remain to be tackled for the Fluid Internet vision to become a reality.

  • A northbound interface for power management in next generation network
           devices
    • Authors: Bolla; R.;Bruschi, R.;Davoli, F.;Donadio, P.;Fialho, L.;Collier, M.;Lombardo, A.;Reforgiato, D.;Riccobene, V.;Szemethy, T.;
      Pages: 149 - 157
      Abstract: Recently, a number of approaches based on dynamic power management techniques have been proposed to reduce the energy consumption of telecommunication networks and devices. They are able to optimize the trade-off between network performance and energy requirements. It is possible to execute and extend these techniques to the whole network, by using local control policies together with energy-aware routing and traffic engineering. However, the lack of a standardized representation of the energy-aware capabilities of heterogeneous networking equipment makes their deployment confusing and impractical. To this aim, we have proposed a novel framework, the green abstraction layer (GAL), whose purpose is to define a multi-layered abstraction interface for the hardware and physical resources, where energy management actions are directly performed. Therefore, the GAL syntax can be exposed to the platform-independent logical representation commonly used in network control protocols. Given the internal architectural complexity and heterogeneity of many network devices, the GAL approach is based on a hierarchical decomposition, where each level provides an abstract and aggregated representation of internal components

  • Management driven hybrid multicast framework for content aware networks
    • Authors: Iorga; R.;Borcoci, E.;Miruta, R.;Pinto, A.;Carneiro, G.;Calcada, T.;
      Pages: 158 - 165
      Abstract: The need for better adaptation of networks to transported flows has led to research on new approaches such as content aware networks and network aware applications. In parallel, recent developments of multimedia and content oriented services and applications such as IPTV, video streaming, video on demand, and Internet TV reinforced interest in multicast technologies. IP multicast has not been widely deployed due to interdomain and QoS support problems; therefore, alternative solutions have been investigated. This article proposes a management driven hybrid multicast solution that is multi-domain and media oriented, and combines overlay multicast, IP multicast, and P2P. The architecture is developed in a content aware network and network aware application environment, based on light network virtualization. The multicast trees can be seen as parallel virtual content aware networks, spanning a single or multiple IP domains, customized to the type of content to be transported while fulfilling the quality of service requirements of the service provider.

  • The impact of application signaling traffic on public land mobile networks
    • Authors: Choi; Y.;Yoon, Cha-hyun;Kim, Young-sik;Heo, S.W.;Silvester, J.A.;
      Pages: 166 - 172
      Abstract: As mobile Internet applications supporting real-time communications services are pervasively used, traffic patterns in mobile networks have changed significantly. New mobile Internet applications differ from traditional applications such as web browser and FTP in that they need always-on connectivity and generate a large amount of signaling traffic. The traffic patterns of these new mobile applications lead to frequent change of radio resource control states between connected and idle in the user equipment, consuming device battery power and causing excessive signaling overhead. The growth in signaling has resulted in a traffic surge that has attracted the attention of mobile network operators. In this article, we first explore traffic composition in a 3G network and show that chatty applications such as instant messenger and social network services contribute to the frequent change of radio states. We then describe the mechanism behind the surge in signaling traffic and describe the disastrous outcome when an application server failure and recovery occurs. Lastly, we discuss some remedies to reduce the application signaling traffic and network load in 3G and LTE networks. These remedies include development of network-aware smart applications that consider the mobile network characteristics and introduction of push notification services. We also present related future work and our research directions.

  • Sustaining life during the early stages of disaster relief with a frugal
           information system: learning from the great east Japan earthquake
    • Authors: Sakurai; M.;Watson, R.T.;Abraham, C.;Kokuryo, J.;
      Pages: 176 - 185
      Abstract: Important lessons for responding to a largescale disaster can be gleaned from the March 11, 2011 Great East Japan Earthquake and tsunami. The failure of the electrical power system and the resultant loss of information communication and processing capability severely constrained the recovery work of many municipalities. It was difficult for supporting organizations to collect and share information. A frugal information system designed around the four u-constructs is suggested as a solution for handling the very early stages of disaster relief, typically within the first 72 hours and even upon the realization of an impending disaster. This article focuses on basing communications on the most frequently available device, the cellular phone, as the foundation for a frugal IS for disaster relief. Familiar and available tools place minimal stress on an already strained communication system, and enable effective connection between those impacted by a disaster and those involved in disaster relief.

  • Telebiometric information security and safety management
    • Authors: Griffin; P.H.;
      Pages: 186 - 192
      Abstract: This article presents proposals to improve the security, safety, and management of biometric systems, and the privacy of system users. First, a standard system heartbeat message is proposed for monitoring the safety, security, performance, and availability of distributed telebiometric devices, and for alerting system administrators to security and safety events and changes. Next, an event journal standard is proposed for the collection of data needed to manage the safe and secure operation of telebiometric devices. Third, a cryptographic message schema standard is proposed for the protection of event journals, heartbeat messages, biometric reference templates, and other telebiometric information using digital signature, encryption, and signcryption techniques.

  • A new global quality of service model: QoXphere
    • Authors: Ibarrola; E.;Saiz, E.;Zabala, L.;Cristobo, L.;Xiao, J.;
      Pages: 193 - 199
      Abstract: The telecommunications sector has experienced significant changes over the past few years. The advent and rise of new applications and services, together with a competitive market, has led to a complex scenario in which quality of service plays a major role. Under this condition, novel QoS regulation and standardization initiatives are required. During the last few years new terms and concepts, such as quality of experience or QoS perceived, have been included in the updated and new QoS-related standards as to better integrate the user??s point of view, as opposed to only network performance parameters. The influence of the user??s satisfaction on the quality of business has also been given increased attention in the regulation and standardization bodies recently. The result is a loose collection of metrics and models that are not standardized and do not integrate all aspects of quality. Such integration is necessary to assure the successful development of this sector. This paper presents a new and integrated QoS model (QoXphere) that is spherical, adaptive, and multi-layered.

  • System level performance of IEEE 802.22-2011 with sensing-based detection
           of wireless microphones
    • Authors: Gronsund; P.;Pawelczak, P.;Park, J.;Cabric, D.;
      Pages: 200 - 209
      Abstract: We present the state-of-the-art system level evaluation of the IEEE 802.22-2011 standard using a highly detailed simulator implementation in NS-2. In the evaluation our attention is focused on the effect of spatiotemporal wireless microphone (WM) activity on the performance of the IEEE 802.22-2011 network, while considering novel spectrum sensing strategies and multimedia traffic with different prioritization in IEEE 802.22-2011. Our general finding is that the IEEE 802.22-2011 standard deals well with WMs and prioritization of simultaneous multimedia traffic using different QoS profiles, while some surprising conclusions follow.

  • Designing intelligent energy harvesting communication systems
    • Authors: Gunduz; D.;Stamatiou, K.;Michelusi, N.;Zorzi, M.;
      Pages: 210 - 216
      Abstract: From being a scientific curiosity only a few years ago, energy harvesting (EH) is well on its way to becoming a game-changing technology in the field of autonomous wireless networked systems. The promise of long-term, uninterrupted and self-sustainable operation in a diverse array of applications has captured the interest of academia and industry alike. Yet the road to the ultimate network of perpetual communicating devices is plagued with potholes: ambient energy is intermittent and scarce, energy storage capacity is limited, and devices are constrained in size and complexity. In dealing with these challenges, this article will cover recent developments in the design of intelligent energy management policies for EH wireless devices and discuss pressing research questions in this rapidly growing field.
