“…Noticeably, this method was designed based on delay information where in case a destination switch doesn't receive monitoring message for a defined period of 50 ms it concludes the presence of a fault in the current path. Ramos et al [25] improved their previous contribution [24] by deploying a proactive failure recovery mechanism by exploiting the information pertaining to the alternative paths available in the packet headers. In this approach, once detecting any link outage it applies alternate paths available without indulging controller.…”

The exponential rise in software computing, low-cost hardware and allied application demands has broadened the horizon for wireless technologies to serve different purposes. Wireless communication systems being central to the modern innovation and industrial growth have given rise to the different communication ecosystems including internet of things, machine to machine communication, wireless local area network, Ad-hoc networks etc. However, coping with non-negotiable service level agreements have forced industries to ensure quality of service (QoS) and quality of experience demands. To meet such demands, software defined network (SDN) has gained widespread attention. The ability to enable higher programmability, flexibility and scalability makes SDN-based system viable; yet, guaranteeing their robustness towards dynamic network, link-failure and adaptive QoS-centric recovery has remained a challenge. In synchronization with this motive, in this paper a robust Heuristic Driven Self-Configuring Proactive Controller is designed for QoS-centric SDN network (HSPC-SDN). Unlike classical data-plane SDN controllers or allied routing solutions, HSPC-SDN performs multiconstraints risk assessment followed by heuristic driven disjoint multiple path selection to support proactive network failurerecovery. HSPC-SDN applies dynamic link-quality information, cumulative congestion degree, probability of successful transmission and link quality change index to perform best forwarding device selection to alleviate any malicious behaviour or malfunction during transmission. Subsequently, it applies genetic algorithm to perform disjoint multiple forwarding cum failure recovery path selection that in conjunction with AND logic function enables self-configuring route recovery to meet fault-tolerant QoS-centric communication. The proposed heuristic model exploits network availability information amalgamated with minimal distance and strictly no-shared component criteria to perform multiple disjoint forwarding-paths cum recovery-path selection. Simulation based results revealed that HSPC-SDN, which can be implemented as a standalone single data-plane controller as well as a middleware routing concept achieves superior average packet delivery rate of 98.03%, packet loss rate of 1.97%, recovery time of 1.66ms and energy consumption of 77.14mJ over other disjoint forwarding path based SDN controllers.

“…In [8], the authors exploit the fast failover group type and BFD to switch between two disjoint paths (working and protected) before a failure occurs in the network. Ramos et al [9] utilize source routing to compute a secondary path for every path and storing it in the packet header along with the primary path. [10] introduces a framework, CORONET, which is a system for recovery from multiple link failures in data plane.…”

Failures are inevitable in an operational network. They can happen anytime in different sizes and components of a network. They impact the network economics regarding CAPEX (Capital Expenditure), OPEX (Operational Expenditure), revenue lost due to service provisioning cut and so on. In order to mitigate the damages resulting from these failures, reactions of network architectures and designs are crucial for the future of the network. Recently, Software Defined Networking (SDN) has got the attention of researchers from both academia and industry as a means in order to increase network availability and reliability due to features, such as centralized automated control and global network view, it promises in networking. To this end, we explore the effects of programmable network architectures, i.e. SDN technology, and traditional network architectures, i.e. MPLS (Multiprotocol Label Switching) technology, on network economics by exploiting Number of Satisfied Service Requests and our predefined Unit Service Cost Scalability metrics under network failure scenarios: i) a random single data plane link failure and ii) a random controller (i.e. control plane) failure. To the best of our knowledge, this study is the first to consider a comparison of a programmable network architecture, i.e. SDN, along with different control plane models, Centralized (Single) Control Plane (CCP), Distributed (Flat) Control Plane (DCP), and Hierarchical Control Plane (HCP), and a non-programmable network architecture, i.e. MPLS, regarding network economics in case of network failures.

“…Their experiments showed that the data plane fault recovery can be achieved in a scalable way within 50 milliseconds using this function. In (Ramos et al, 2013b), Ramos et al extended their previous study (Ramos et al, 2013a) and developed a proactive failure recovery scheme by carrying the information of alternative paths in the packet headers. Thus, when a link failure happens, their system uses alternative path information in order to maintain communication without consulting the controller.…”

Failures in networks result in service disruptions which may cause deteriorated Quality of Service (QoS) for the end users. Since SDN is becoming the mainstream paradigm for networks, implementation of a robust fault tolerance scheme for SDN-based networks is crucial. Existing SDN data plane fault tolerance approaches can be classified as reactive and proactive which may or may not rely on the controller, respectively. However, none of them qualifies as a complete solution, providing only partial remedies. In this work, we propose Dynamic Protection with Quality of Alternative Paths (DPQoAP) that considers not only the existing faults within the network but also the quality of alternative paths. As a result, we can sustain the QoS throughout the network after the recovery. We also investigate how application based parameters are affected by link failures. To this end, we explore the change in Quality of Experience (QoE) caused by link failures under different cases using Dynamic Adaptive Streaming over HTTP (DASH) for video streaming. On the other hand, even though DASH is proposed as a solution to improve the QoE affected by the dynamic conditions of the networks, it remains insufficient to handle the congested links that show the symptoms of a link failure. Thus, we apply the data plane fault tolerance approach in SDN to improve the QoE of DASH clients in the case of congestion as well as the failure. The performance of the proposed solutions are evaluated through various experiments considering the QoS and QoE parameters. It is observed that DPQoAP enhances the efficiency of the networking operations and adaptability of the applications.
