  • Guest editorial: Spatially and spectrally flexible elastic optical
    • Authors: Tomkos; Ioannis;Miyamoto, Yutaka;Wellbrock, Glenn;Winzer, Peter J.;
      Pages: 20 - 22
      Abstract: The traffic carried by core optical networks as well as the per-channel interface rates required by IP routers are growing at a remarkable pace year after year. This trend is due to the widespread deployment of fixed and wireless broadband access networks, the huge growth of video-based services supported by the Internet, and social media applications, as well as a substantially growing amount of machine-to-machine traffic supporting a variety of data-centric applications. Optical transmission and networking advancements have been able to satisfy this huge traffic growth so far by providing the necessary network infrastructure in a cost- and energy-efficient manner, utilizing to the maximum extent the capabilities of optoelectronic and photonic devices across the available bandwidth of deployed optical fibers. However, as we are rapidly approaching fundamental spectral efficiency limits of single-mode fibers, the scientific and industrial telecommunications community foresees that the growth capabilities of conventional WDM networks operating on a fixed frequency grid in conventional wavelength bands are quite limited.

      Pages: 24 - 33
      Abstract: Given the introduction of coherent 100G systems has provided enough fiber capacity to meet data traffic growth in the near term, enhancing network efficiency will be service providers' high priority. Adding flexibility at the optical layer is a key step to increasing network efficiency, and both spectral and spatial functionality will be considered in next generation optical networks along with advanced network management to effectively harness the new capabilities.

  • Migration from fixed grid to flexible grid in optical networks
    • Authors: Xiaosong Yu;Tornatore; M.;Ming Xia;Jianping Wang;Jiawei Zhang;Yongli Zhao;Jie Zhang;Mukherjee, B.;
      Pages: 34 - 43
      Abstract: Optical WDM backbone networks based on fixed spectrum grid have limitations such as low spectrum utilization and rigidity in provisioning for heterogeneous rates. Flexible-grid technologies can alleviate these limitations for on-demand provisioning. These technologies represent promising candidates for future optical networks supporting beyond-100-Gb/s signals. However, a one-time green-field deployment of flexible-grid technologies may not be practical, as the already-made investment in existing fixed-grid WDM networks needs to be preserved, and interruptions to ongoing services need to be minimized. Therefore, we envision that fixed-and flexible-grid technologies will coexist, which will bring the challenge of interoperating fixed-and flexible-grid equipment. It is also important to design the optimum migration strategy to maximize cost effectiveness and minimize service interruption. In this article, we discuss the key aspects of network architectures supporting coexistence of fixed and flexible grid technologies, and outline the challenges of network operations. We also propose and evaluate different migration strategies from fixed grid to flexible grid under different network scenarios.

    • Authors: Ryf; R.;Chandrasekhar, S.;Randel, S.;Neilson, D.T.;Fontaine, N.K.;Feuer, M.;
      Pages: 52 - 59
      Abstract: Fiber optic communication networks in the era of large data centers are required to provide large capacity, often orders of magnitude larger than the capacity of a single-mode fiber. The transport capacity must also be rapidly reconfigurable to adapt to the applications and services provided by the data centers. This article explores new transponders capable of providing larger capacities and making optimal use of the optical transmission spectrum, new optical switches capable of flexible routing of wavelength and multiple spatial channels, and new amplifiers supporting multiple spatial channels and broad optical bandwidth.

  • Switching solutions for WDM-SDM optical networks
    • Authors: Marom; D.M.;Blau, M.;
      Pages: 60 - 68
      Abstract: Over the last few decades, network traffic has consistently grown at an exponential rate and was efficiently satisfied using WDM and more efficient coding schemes requiring coherent detection. There is no indication that the network traffic growth trend will cease anytime soon, and we are nearing the day when the capacity of the ubiquitous single-mode fiber will be fully exploited. Space-domain multiplexing (SDM) for high-capacity transmission is the promising solution with the scaling potential to meet future capacity demands. However, there is still a large technological gap between current WDM optical communication system designs and SDM network implementations. In this article we lay the foundation of switching node designs for future WDM-SDM optical networks.

  • Spectrally and spatially flexible optical network planning and operations
    • Authors: Klonidis; D.;Cugini, F.;Gerstel, O.;Jinno, M.;Lopez, V.;Palkopoulou, E.;Sekiya, M.;Siracusa, D.;Thouenon, G.;Betoule, C.;
      Pages: 69 - 78
      Abstract: The advent of spectrally flexible (a.k.a. elastic) optical networking is widely identified as the next generation optical network solution that permits varying bandwidth demands to be dynamically assigned over flexible spectral containers, targeting optimum use of the available network resources. Additionally, the adoption of the space dimension is identified as a promising solution for the capacity expansion of future networks, while novel spatial-spectral switching solutions show that the flexible networking concept can be further expanded over both the spatial and spectral dimensions. This article provides an overview of the latest developments and possible approaches with respect to flexible optical networking and the emerging benefits that spatially flexible networking approaches can offer. The focus is on the network planning and resource optimization functions, the main network operations related to fragmentation and IP/optical layer integration, and the control plane solutions.

  • 3D elastic optical networking in the temporal, spectral, and spatial
    • Authors: Proietti; R.;Lei Liu;Scott, R.P.;Binbin Guan;Chuan Qin;Tiehui Su;Giannone, F.;Yoo, S.J.B.;
      Pages: 79 - 87
      Abstract: Conventional elastic optical networking, EON, uses elasticity in two domains, time and frequency, to optimize utilization of optical network resources in the presence of fluctuating traffic demand and link quality. Currently, networking exploiting a third domain, space, is the focus of significant research efforts since space-division multiplexing, SDM, has the potential to substantially improve future network capacity and spectral efficiency. This article extends 2D-EON to include elasticity in all three domains: time, frequency, and space. We introduce enabling technologies, architectures, and algorithms for 3D-EONs. Based on sample network topologies, we investigate algorithms for routing, spectrum, spatial mode, and modulation format assignment - RSSMA. In particular, we investigate fragmentation-aware RSSMA and how the constraints in the formation of super-channels in MIMO-based SDM systems can impact the network performance in terms of blocking probability.

  • Guest editorial: Network and service virtualization

      Abstract: The introduction of software-defined networking (SDN) and network function virtualization (NFV) has altered, in a wholesale manner, the way to plan for network infrastructure evolution in the forthcoming decade. This Feature Topic aims to provide a concise reference entry point to a wider audience with respect to carrier-grade networking and service virtualization with emphasis on automating the entire networking and cloud infrastructure. The first steps in network virtualization are already taking place today, although more often than not through a piecemeal approach that simply replaces hardware-based network appliances with software-based alternatives. This may help to reduce operator costs in the mid-term but does not alter the full life cycle of service creation and deployment. The real potential for network and service virtualization lies in upgrading the entire toolbox network operators have at their disposal, as state-of-the-art research and development efforts already indicate. For example, the European FP7 UNIFY project defines an architecture where the entire network, from home devices to data centers, forms a unified production environment, a dynamic service creation platform able to distribute functions and state anywhere in the network, aided by automated orchestration engines; see for more details. While drafting the Call for Papers for this Feature Topic, our first goal was to attract high-quality contributions from operator and industry research labs as this topic is particularly pertinent to practitioners in the field. Carriers, in particular, can be the main beneficiaries from the emerging infrastructures based on NFV, SDN, and cloud technologies. Therefore, articles by authors working at global operators currently developing, evaluating, and standardizing solutions for network and service virtualization were particularly welcome and encouraged. In this sense, we are glad that all five selected papers for publication in this issu- are penned by experts affiliated with European, American, and Asian carriers.

    • Authors: Bo Han;Gopalakrishnan; V.;Lusheng Ji;Seungjoon Lee;
      Pages: 90 - 97
      Abstract: Network function virtualization was recently proposed to improve the flexibility of network service provisioning and reduce the time to market of new services. By leveraging virtualization technologies and commercial off-the-shelf programmable hardware, such as general-purpose servers, storage, and switches, NFV decouples the software implementation of network functions from the underlying hardware. As an emerging technology, NFV brings several challenges to network operators, such as the guarantee of network performance for virtual appliances, their dynamic instantiation and migration, and their efficient placement. In this article, we provide a brief overview of NFV, explain its requirements and architectural framework, present several use cases, and discuss the challenges and future directions in this burgeoning research area.

  • Toward a telco cloud environment for service functions
    • Authors: Soares; J.;Goncalves, C.;Parreira, B.;Tavares, P.;Carapinha, J.;Barraca, J.P.;Aguiar, R.L.;Sargento, S.;
      Pages: 98 - 106
      Abstract: Deploying service functions, SFs, is an essential action for a network provider. However, the action of creating, modifying and removing network SFs is traditionally very costly in time and effort, requiring the acquisition and placement of specialized hardware devices and their interconnection. Fortunately, the emergence of concepts like cloud computing, SDN, and ultimately NFV is expected to raise new possibilities for the management of SFs with a positive impact in terms of agility and cost. From a telco viewpoint these concepts can help to both reduce OPEX and open the door to new business opportunities. In this article, we identify how téleos can benefit from the abovementioned paradigms, and explore some of the aspects that still need to be addressed in the NFV domain. We focus on two major aspects: enabling telco infrastructures to adopt this new paradigm, and orchestrating and managing SFs toward telco-ready cloud infrastructures. The technologies we describe enable a telco to deploy and manage SFs in a distributed cloud infrastructure. In this context, the Cloud4NFV platform is presented. Special attention is given to the way SFs are modeled toward cloud infrastructure resources. In addition, we explore the ability to perform service function chaining as one of the fundamental features in the composition of SFs. Finally, we describe a proof of concept that demonstrates how a telco can benefit from the described technologies.

      Pages: 107 - 115
      Abstract: Mobile packet core networks are undergoing major changes to meet the requirements of the future data tsunami, enhance network flexibility, and reduce both CAPEX and OPEX. In this regard, SDN and NFV technologies have gained great momentum among the teleos, with the promise of interoperability, programmability, and on-demand dynamic provisioning. In this article, we present work being developed in the Mobile Packet Core project within the ONF Wireless & Mobile Working Group regarding SDN architecture for the Mobile Packet Core. In addition, we propose an SDN-based MPC in the NFV context in order to facilitate dynamic provisioning of MPC network functions. Finally, a potential control architecture considering both SDN and NFV is proposed.

  • vConductor: An enabler for achieving virtual network integration as a
    • Authors: Wenyu Shen;Yoshida; M.;Minato, K.;Imajuku, W.;
      Pages: 116 - 124
      Abstract: Network function virtualization is regarded as a promising candidate for future networks. Although many advantages are expected, there is still a lack of services that directly link to increased revenue for telecom operators. Therefore, we propose a new NFV-based service, virtual network integration as a service (VNIaaS). The service allows enterprise network administrators to construct and monitor virtual enterprise networks as necessary. As a key enabler, we further propose vConductor, an innovative technology due to its automatic network provisioning, multi-objective resource scheduling, and NFV-oriented inventory management characteristics. Finally, we show the feasibility through implementation of a prototype system. We believe that this contribution will be a catalyst to accelerate the industrialization of NFV.

  • An instrumentation and analytics framework for optimal and robust NFV
    • Authors: Veitch; P.;McGrath, M.J.;Bayon, V.;
      Pages: 126 - 133
      Abstract: This article details a novel approach to the fine-tuning of carrier-grade virtualized network function deployments for both performance optimization and diagnostic purposes, using embedded instrumentation with an analytics framework. The work presented in this article is the output of a co-lab established between BT and Intel Labs Europe to investigate network-function-virtualization-related problems faced by traditional telecom operators. Results from comprehensive testing of virtual CDN and WAN acceleration use cases are presented. These results led to the development of a number of insights that will help network operators optimize the deployment of NFV on standard high volume servers. Significantly, it was found that the default configuration for some use cases resulted in suboptimal resource allocation and consumption. Consequently, opportunities exist for carriers to fine-tune their NFV deployments from both the technical and economic perspectives using approaches such as embedded instrumentation.

  • Series editorial: Optical multi-service core and access networks
    • Authors: Gebizlioglu; Osman S.;Jain, Vijay;
      Pages: 134 - 135
      Abstract: The emerging trends of 2013 grew to dominate the two most notable developments in 2014: 1) the packet optical transport system (P-OTS) concept with the service provider goal to build a common network infrastructure by integrating Ethernet, IP/MPLS, and DWDM; 2) intensifying focus and attention on network functions virtualization (NFV) and software-defined networking (SDN) to give service providers the tools for more effective operation and management of communications networks in general, and optical communications networks in particular. All major global service providers have been establishing and announcing their target timeframes for transitioning to all-IP network operations, while major industry standards organizations and fora have been striving to publish their guidelines and frameworks for NFV and SDN. These important trends are expected to gain additional momentum through 2015 as the industry continues to rise to the challenges of meeting the growing global communications needs.

  • Energy-efficient resilient optical networks: Challenges and trade-offs
    • Authors: Yabin Ye;Jimenez Arribas; F.;Elmirghani, J.;Idzikowski, F.;Lopez Vizcaino, J.;Monti, P.;Musumeci, F.;Pattavina, A.;Van Heddeghem, W.;
      Pages: 144 - 150
      Abstract: Energy efficiency and resilience are two well established research topics in optical transport networks. However, their overall objectives (i.e., power minimization and resource utilization/ availability maximization) conflict. In fact, provisioning schemes optimized for best resilience performance are in most cases not energy-efficient in their operations, and vice versa. However, very few works in the literature consider the interesting issues that may arise when energy efficiency and resilience are combined in the same networking solution. The objective of this article is to identify a number of research challenges and trade-offs for the design of energy-efficient and resilient optical transport networks from the perspective of long-term traffic forecasts, short-term traffic dynamics, and service level agreement requirements. We support the challenges with justifying numbers based on lessons learned from our previous work. The article also discusses suitable metrics for energy efficiency and resilience evaluation, in addition to a number of steps that need to be taken at the standardization level to incorporate energy efficiency into already existing and well established protocols.

      Pages: 152 - 162
      Abstract: In this work we detail the strategies adopted in the European research project IDEALIST to overcome the predicted data plane capacity crunch in optical networks. In order for core and metropolitan telecommunication systems to be able to catch up with Internet traffic, which keeps growing exponentially, we exploit the elastic optical networks paradigm for its astounding characteristics: flexible bandwidth allocation and reach tailoring through adaptive line rate, modulation formats, and spectral efficiency. We emphasize the novelties stemming from the flex-grid concept and report on the corresponding proposed target network scenarios. Fundamental building blocks, like the bandwidth-variable transponder and complementary node architectures ushering those systems, are detailed focusing on physical layer, monitoring aspects, and node architecture design.

      Abstract: This article reports the work on next generation transponders for optical networks carried out within the last few years. A general architecture supporting super-channels (i.e., optical connections composed of several adjacent subcarriers) and sliceability (i.e., subcarriers grouped in a number of independent super-channels with different destinations) is presented. Several transponder implementations supporting different transmission techniques are considered, highlighting advantages, economics, and complexity. Discussions include electronics, optical components, integration, and programmability. Application use cases are reported.

      Pages: 172 - 181
      Abstract: As traffic demands become more uncertain and newer services continuously arise, novel network elements are needed to provide more flexibility, scalability, resilience and adaptability to today's optical networks. Considering these requirements, within the European project IDEALIST the investigation of elastic optical networks is undertaken with special focus on next generation optical node architectures. As an evolution of existent ROADMs and OXCs, these optical nodes will establish a new paradigm in which the network requirements will be efficiently addressed considering various emerging dimensions. In this article, we describe the drivers, architectures, and technologies that will enable these novel optical nodes. In addition, multivendor traffic interoperability, optical defragmentation, and node cascadability are also described as considerations in the node design.

  • A west-east bridge based SDN inter-domain testbed
    • Authors: Pingping Lin;Jun Bi;Wolff; S.;Yangyang Wang;Anmin Xu;Ze Chen;Hongyu Hu;Yikai Lin;
      Pages: 190 - 197
      Abstract: SDN is considered to be a promising way to re-architect the Internet. However, the Internet is managed by owners of different administrative domains, so the centralized control model of SDN must be extended to account for inter-domain traffic. Thus, this article proposes a WE-Bridge mechanism to enable different SDN administrative domains to peer and cooperate. Based on WE-Bridge, we further designed two innovative inter-domain routing applications as use cases. To verify our design, we implemented the WE-Bridge and the two use cases by building an international testbed on which WE-Bridge, together with the two use cases, are deployed. The testbed is composed of four SDN networks: CERNET, Internet 2 in USA, CSTNET, and SURFnet.

  • Detection of false data injection attacks in smart-grid systems
    • Authors: Po-Yu Chen;Shusen Yang;McCann; J.A.;Jie Lin;Xinyu Yang;
      Pages: 206 - 213
      Abstract: Smart grids are essentially electric grids that use information and communication technology to provide reliable, efficient electricity transmission and distribution. Security and trust are of paramount importance. Among various emerging security issues, FDI attacks are one of the most substantial ones, which can significantly increase the cost of the energy distribution process. However, most current research focuses on countermeasures to FDIs for traditional power grids rather smart grid infrastructures. We propose an efficient and real-time scheme to detect FDI attacks in smart grids by exploiting spatial-temporal correlations between grid components. Through realistic simulations based on the US smart grid, we demonstrate that the proposed scheme provides an accurate and reliable solution.

  • SMART for mobile health: A study of scheduling algorithms in full-IP
           mobile networks
    • Authors: Anpeng Huang;Linzhen Xie;
      Pages: 214 - 222
      Abstract: As a joint initiative of WHO and ITU, mHealth is becoming a feasible tool to offer data-intensive healthcare services online. In general, each kind of mHealth application has user-specific service-quality requirements that could be satisfied in the cost of bandwidth overconsumption. In any mobile network, bandwidth overconsumption is selfishly competing with limited radio resources. This phenomenon is further magnified by the “best-effort” service pattern inherited from IP networking, and the influence from interference, fading, and other mobility effects on unreliable radio channels. To enrich mHealth applications, we propose a Service-Mapping Adaptive Radio Transmission (SMART) scheduling algorithm, in which system parameters (QCI, CQI, MCS in AMC, etc.) are employed to enable “better than best effort” packet-switching services in full-IP mobile networks (e.g. LTE/LTE-Advanced). In this proposal, the designed scheduling metric is a self-adaptive mechanism that can combine mobile service-quality inspection and transmission pattern recognition dynamically. System-level simulation experiments demonstrate that the proposal can obtain approximately 31.25 percent gain on average, in contrast to existing solutions. Additionally, the runtime complexity of this solution is lowered to O(K log K), where K is the number of mHealth users within a cell.
