“…In Reference 14, the authors present a rule compressor strategy using “Ruleblender” scheme which uses spanning tree to for match algorithm as well as they reduced the size of the packet. They incorporate the jump flow to divide the rules in sections and finally claimed to decrease the flow table burden at the forwarding plane.…”

“…13 Another problem arises in UDP scenario is the duplicate packets which makes the packet to be disorderedly arrived at destination. 14 This research focuses the delay issues during this control (secure channel) communication between the OpenFlow switch and controller. This research aimed to carefully address the parameters involve in communication mechanism between controller and switch to mitigate the latency and overburdening issues, to optimize the QoS parameters which ultimately enhance the overall performance of the SDN networks.…”

Software Defined Networks (SDN) is now the leading framework for the existing network infrastructure. Increasing Internet traffic leads to attract SDN infrastructure in large networks like enterprise or data centers by using logical centralize control concept. This abstraction, flexibility, and agility enable the network managers to view the global picture of the network and flow the traffic in an efficient way to avoid congestion and traffic delay issues. However, besides the benefits, the internal mechanism of SDN has some serious challenges, which leads flow table overflow, congestions, controller and switch overloading, link failure and latency issues. This research focus on the delays produced during communication between control plane and data plane due to the parameters like rule formation, mismatches, buffer/queue constraints, flow entries, controller resource utilization or duplicate flow packets, and unordered packets. These delays become more critical in large networks especially in-case of reactive modes. Furthermore, the frequent rule composition and installation causes extra burden at the controller, this control communication needs prompt reply to forward the traffic in a stipulated time. This article presents the Efficient Resource Management Scheme (ERMS), which efficiently handle the inter-communication delay and minimize the network overheads. The experiment results depict the better performance of ERMS during the communication between controller and switch by efficient packet handling and flow rules management while minimizes the overheads on controller.The proposed solution enhances the performance of SDN networks by improving the quality of services parameters.

“…For example, in the topology in Figure 2, the controller computes two paths passing between switches A and G and installs flow rules along two paths (e.g., (A-B-G) and (A-C-D-G)). This mechanism is faster than the reactive failure recovery mechanism because there is less controller intervention during link failure [5,6]. However, there are also some disadvantages associated with this mechanism.…”

Reliability Aware Multiple Path Installation in Software-Defined Networking

et al. 2021

Link failures frequently occur in communication networks, which negatively impacts network services delivery. Compared to traditional distributed networks, Software-Defined Networking (SDN) provides numerous benefits for link robustness to avoid services unavailability. To cope with link failures, the existing SDN approaches compute multiple paths and install corresponding flow rules at network switches without considering the reliability value of the primary computed path. This increases computation time, traffic overhead and end-to-end packets delay. This paper proposes a new approach called Reliability Aware Multiple Path Flow Rule (RAF) that calculates links reliability and installs minimum flow rules for multiple paths based on the reliability value of the primary path. RAF has been simulated, evaluated and compared with the existing approaches. The simulation results show that RAF performs better than the existing approaches in terms of computation overhead at the controller and reduces end-to-end packet delay and traffic overhead for flow rules installation.

“…Legacy Wide-Area-Networks (WAN) architectures, like MPLS-IP and MPLS-TP [6], create limitations as energy utilities adopt the cloud or utilize commodity Internet connections in their operational technology (OT) networks. The enterprises or energy sector, that is the main application discussed in this article, are shifting to Software-Defined Wide Area Network (SD-WAN) to ensure seamless cloud migration, reduced capital expenditure (CAPEX), infrastructure automation, virtualisation and improved user collaboration [7].…”

Software-defined Wide Area Network (SD-WAN) is an elementary change in the way network architects and service providers transpose their focus from hardware to the software oriented paradigm. Using a virtual network overlay, SD-WAN classifies and prioritizes how each application goes through the network based on business priority, quality of service (QoS), service-level agreements (SLAs) and security requirements. In this paper, we presented a system level concept and implementation of AI secured SD-WAN technology that is helping service providers to easily connect to and integrate across all the different IoT compute edges required to optimize the traffic and management of 5G cells. This architecture will enable a seamless transition for energy sector towards a full 5G connectivity by managing any data available across the edge, leveraging 5G transport for those critical applications that require ultra-low latency and higher bandwidths. Moreover, we weigh the pros and cons of using hybrid Multi-protocol Label Switching (MPLS) with SD-WAN to provide seamless integration, scalability and flexibility to the energy sector.
