“…Additionally, for faster troubleshooting of OF@TEIN playground, we can generate various visualizations from aggregated, integrated, and classified visibility data and arrange them into interactive dashboards. After integration, a single data instance has eighty-three metrics available for further analysis while flow-centric visibility that was proposed in [28] had seven metrics available for further analysis. To show some of these metrics, we have created a dashboard that presents four charts as shown in Figure 14.…”

Modern information communication technologies (ICT) infrastructures are getting complicated to cope with the various demands needed to accommodate the emerging technology paradigms such as cloud, software-defined networking (SDN), and internet of things (IoT). Visibility is essential for the effective operation of such modern ICT infrastructures to easily pinpoint server faults, network bottlenecks, and application performance troubles. Even though many conventional monitoring solutions are now available, multi-layer visibility is still limited when operating such complicated infrastructures. To address this particular limitation, a futuristic multi-layer visibility framework denoted as SmartX multi-view visibility framework (MVF), is proposed for unifying the visibility of underlay, physical and virtual resources, flow, and workload layers. To unify multi-layer visibility, this paper presents a comprehensive extension of SmartX MVF with flow-centric visibility for simultaneously monitoring physical-virtual resources, flows classification, and visualization to eventually assist secured operation of SDN-enabled multisite cloud infrastructure. Flow-centric visibility design has five main components (1) a lightweight network packets-precise flows visibility collection component, (2) a visibility data aggregation and tagging component, (3) a multi-layer visibility data integration component, (4) a non-learning-based network packets flows classification component, and (5) a visualization component. Furthermore, a prototype implementation of SmartX MVF with flow-centric visibility is deployed in an SDN-enabled multisite cloud playground to verify the proposed multi-view visibility of fine-grained flow-aware physical-virtual resources.

“…NFV is assisting SDN by deploying virtualized network functions in the box-style hyper-converged resources of cloud data centers [21]. Virtual monitoring is used to collect box-related data for monitoring and troubleshooting purposes, which one of them is described in our previous work [22]. Moreover, the centralized orchestration for multi-tenant cloud data centers and NFV-assisted SDN infrastructure can provide the simplified orchestration of SDI-ready playground with the slice-based network virtualization support.…”

Next, the OF@TEIN Playground is enhanced with multiple mesh-style inter-connections of NVGRE/VXLAN overlay tunnels, along with a unique flow-tapping virtual switch [22]. The OpenStack multi-region deployment is modified to build an SDN-enabled multi-site playground where inter-VM connectivities between cloud VMs are used by leveraging OpenFlow-enabled data planes.…”

In this paper, we present our proposals and efforts for building an affordable playground (i.e., miniaturized testbed) for Software-Defined Networking (SDN)-Cloud experiments by using hyper-converged SmartX Boxes that are distributed across multiple sites. Each SmartX Box consists of several virtualized functions that are categorized into SDN and cloud functions. Multiple SmartX Boxes are deployed and inter-connected through SDN to build multi-site distributed cloud playground resources. The resulting deployment integrates both cloud multi-tenancy and SDN-based slicing, which allow developers to run experiments and operators to monitor resources in a distributed SDN-cloud playground. It also describes how the hyper-converged SmartX Box can increase the affordability of the playground deployment. Thus, the analysis result shows the efficiency of SmartX Box for building a distributed playground by providing semi-automated DevOps-style resource provisioning.

Network architectures nowadays are not able to address the requirements of future Internet, as they are not sufficient, ossified, and are power hungry on the TCP/IP paradigm. Therefore, to promote the realizable progression toward the new paradigms and modern protocols, modern routers are required to become programmable for the flexible control and dynamic management of both power states and traffic flows. In this scenario, Software Defined Networking (SDN) is considered as an exemplary approach for providing the support of dynamic traffic flows of each node on a network. Besides the benefits that SDN brought to the networking area, there are still crucial challenges such as to design an effective, lightweight API, rich algorithms, and traffic forwarding rules for SDN layers along with the adoption of an energy efficient infrastructure that could have the least effect on the environment. The aim of this research is to drive the attention toward environment friendly adoption and implementation of SDN that could deal with the growing number of users and network equipment. For this purpose, in this research, a comprehensive review on SDN while mapping the characteristics of green computing with SDN is provided. In addition to that, the research stressed on the benefits of Green SDN through a proposed G-SDN framework. Some well-defined case studies are presented to highlight the need of greening an SDN infrastructure. Finally, various research directions are presented to the wide adoption of SDN technology for academia and industry alike. KEYWORDS green computing, green SDN, SDN, software defined networks 1 INTRODUCTION Software Defined Networking (SDN) offers a high level of flexibility, controllability, and programmability in networks with the power of centralized control. The centralized controller at SDN faces a significant performance drawback when dealing with huge network flows. 1 On the other hand, features provided by SDN allows an ease in deploying the strategies that are designed to overcome the existing problems of power and energy-waste. 2 Green computing refers to the reduction of hazard and toxic materials, improved efficiency of energy including recycling of factory wastage, 3 and it has become an integral part to enhance the reliability of each emerging computing domains. Even the cloud and green computing are applicable side by side to make greener internet and enhance services. The former techniques allow the services with ease when required at a cost of complex infrastructure. However, the later approach has edge in providing all of these services with efficient energy usage, recyclability, low environmental impact, reduced carbon emission, and much more facilities. 4 In addition, to provide the promising services to the intended users, wired and wireless networks 5,6 have been followed by many directions in prior studies 5-7 such as the closing of forward and feedback loops. 8 In this way, there exists a variety of designs such as low-power solutions with slow and fast dynamics. Solutions with sl...
