“…Hu et al further [17] study the controller placement problem for reliability and propose a greedy algorithm to achieve an efficient placement and reliability. The general goal of Survivor [18] is to maximize connectivity between forwarding devices and controllers instances. Their study verifies that the path diversity can increase the survivability during fail over states.…”

Abstract-One grand challenge in Software Defined Networking (SDN) is to select appropriate locations for controllers to shorten the latency between controllers and switches in wide area networks. In the literature, the majority of approaches are focused on the reduction of packet propagation latency, but propagation latency is only one of the contributors of the overall latency between controllers and their associated switches. In this paper, we explore and investigate more possible contributors of the latency, including the end-to-end latency and the queuing latency of controllers. In order to decrease the end-to-end latency, the concept of network partition is introduced and a Clustering-based Network Partition Algorithm (CNPA) is then proposed to partition the network. The CNPA can guarantee that each partition is able to shorten the maximum end-to-end latency between controllers and switches. To further decrease the queuing latency of controllers, appropriate multiple controllers are then placed in the subnetworks. Extensive simulations are conducted under two real network topologies from the Internet Topology Zoo. The results verify that the proposed algorithm can remarkably reduce the maximum latency between controllers and their associated switches.

Abstract-Resilience against disaster scenarios is essential to network operators, not only because of the potential economic impact of a disaster but also because communication networks form the basis of crisis management. COST RECODIS aims at studying measures, rules, techniques and prediction mechanisms for different disaster scenarios. This paper gives an overview of different solutions in the context of technology-related disasters. After a general overview, the paper focuses on resilient Software Defined Networks.

“…Muller et al [43] highlight that even if the control and data planes are compromised, different placement strategies of the network controller, path diversity and distinct recovery mechanisms can be used to ensure that the network can still function. Note that similar techniques can be used not only to improve aspects related to Survivability but also to Disruption Tolerance.…”

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.
