“…Understanding the resilience properties of the network requires modelling this complex structure as a whole such that challenges can be applied to model the impact on user services. Resilience is the ability of the network to provide and maintain service in the face of challenges to the network [133]. Resilience subsumes survivability (tolerance of correlated failures from large-scale disasters and attacks), disruption tolerance (for weakly connected channels, mobil- ity, unpredictable delay, and energy constraints), dependability (including reliability and availability), and performability (that measures degraded performance of a complex system when some of its subsystems fail).…”

In this position paper on reliable networks, we discuss new trends in the design of reliable communication systems. We focus on a wide range of research directions including protection against software failures as well as failures of communication systems equipment. In particular, we outline future research trends in software failure mitigation, reliability of wireless communications, robust optimization and network design, multilevel and multirealm network resilience, multiple criteria routing approaches in multilayer networks, resilience options of the fixed IP backbone network in the interplay with the optical layer survivability, reliability of cloud computing networks, and

“…A challenge is an atypical event that hinders the expected normal network operation [6,8]. In order to deal with a wide range of challenges, network resilience encompasses six major disciplines: security, survivability (including fault tolerance), performability, traffic tolerance, disruption tolerance and dependability [7]. When a network challenge arises, mitigation mechanisms should be activated, ideally without human intervention, to rapidly protect a network and the services it supports.…”

“…Thus, they me discussed in all sections or could be treated in a separate section. Otherwise it should be clarified to which energy issues you are referring to and why.>>> We insert energy issues within the Disruption Tolerance discipline following accordance with the taxonomy on network resilience and challenges proposed by Sterbenz et al [7]. According with this taxonomy, the consequence of challenges associated with energy issues is link disruptions, and the most studied aspects about energy include (i) optimization of energy consumption in the network and (ii) network resilience when power outages occur.…”

Resilience support in software-defined networking: A survey

Software-Defined Networking (SDN) is an architecture for computer networking that provides a clear separation between network control functions and forwarding operations. The abstractions supported by this architecture are intended to simplify the implementation of several tasks that are critical to network operation, such as routing and network management. Computer networks have an increasingly important societal role, requiring them to be resilient to a range of challenges. Previously, research into network resilience has focused on the mitigation of several types of challenges, such as natural disasters and attacks. Capitalising on its benefits, including increased programmability and a clearer separation of concerns, significant attention has recently focused on the development of resilience mechanisms that use software-defined networking approaches. In this article, we present a survey that provides a structured overview of the resilience support that currently exists in this important area. We categorize the most recent research on this topic with respect to a number of resilience disciplines. Additionally, we discuss the lessons learned from this investigation, highlight the main challenges faced by SDNs moving forward, and outline the research trends in terms of solutions to mitigate these challenges . 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 This article presents a survey on the support for network resilience in SoftwareDefined Networking (SDN). This has been the subject of intense investigation by the academic and industrial community in the past few years, as evidenced by the number of papers included in our survey (159 references in total). Capitalizing on the benefits of SDN, including increased programmability and a clearer separation of concerns, significant attention has recently focused on the development of resilience mechanisms that use software-defined networking approaches. Thus, a wide range of solutions to classical network problems have been revisited using this architecture, but many problems continue to be challenging.Our survey investigates the resilience support that currently exists in this important area, and categorizes the most recent research on this topic with respect to a number of resilience disciplines. Additionally, we discuss the lessons learned from this investigation, highlight the main challenges faced by SDNs moving forward, and outline the research trends in terms of solutions to mitigate these challenges. The aim of the survey is to offer to the reader a structured view of network resilience in the SDN spectrum, and how resilience aspects are supported in these architectures.We believe that this subject material is closely aligned with the objectives of the journal. Please be assured that:1. This paper has not been published or accepted for publication w...

“…Transmission reliability can be improved by using network survivability mechanisms aimed at providing the continuous service in the presence of failures [7][8][9]. They were originally proposed for wired networks, and typically utilize the idea of backup (alternate) paths [10] forwarding the traffic after failures of links/nodes affecting the respective primary paths of transmission.…”

Wireless Mesh Networks, offering transmission rates of 1-10 Gb/s per a millimeter-wave link (utilizing the 71-86 GHz band) seem to be a promising alternative to fiber optic backbone metropolitan area networks because of significantly lower costs of deployment and maintenance. However, despite providing high transmission rates in good weather conditions, high-frequency wireless links are very susceptible to weather disruptions. In particular, heavy rain storms may lead to remarkable signal attenuation. In this paper, we introduce a new transmission technique for wireless mesh networks to mitigate the negative effects of link quality degradation due to rain storms. In particular, our method is the first one to use information on forecasted attenuation of links based on radar measurements to perform in advance the periodic updates of a network topology. Our approach is easily implementable in practice, since functionality of dynamic antenna alignment is currently offered by a number of equipment vendors. Other contributions of the paper include presentation of the ILP model of weatherresistant links formation problem followed by analysis of its computational complexity. Results of simulations, performed for three real scenarios of rain storms, show that our approach is very efficient in reducing the level of signal attenuation.
