“…With this goal in mind, we set a first experiment carrying out the Network Topology Discovery Time (NTDT) procedure following the benchmarking tests for network topology discovery time guidelines provided by the RFC 8456 (item 5.1.1 6 ). The NTDT experiment aims to come up with the total time spent in the SDN controller for converging topology bootstrap information and generating the corresponding network events.…”

“…The adoption of the SDN paradigm in scenarios consisting VOLUME 4, 2016 of emerging technologies, such as Information-Centric Networks (ICN) [5], Cloud Computing [6], Internet of Things (IoT) [7], 5G [8], among others, has proved to be a key factor in making it possible to meet the stringent requirements of each provided service (e.g., ultra-low latency, reliability, and availability). In these challenging scenarios, the SDN orchestration capabilities mean the perspectives provided by the SDN approach by employing flexibility and dynamicity by reducing the complexity imposed by several control plane technologies [9].…”

Enhancing Orchestration and Infrastructure Programmability in SDN With NOTORIETY

Software-Defined Networking (SDN) controllers are nowadays expected to manage large infrastructures and services in a practical, efficient, and optimized way. To achieve such control, SDN networks should increase the automation of orchestration functions to fullfil both service and network management lifecycles. However, network management applications have stringent resource demands that orchestrators need to honor. Most of the available orchestrators focus on high-level approaches that rely exclusively on the Northbound API (NB-API). A few strategies have also been designed to optimize the controllers' internal mechanisms through features enabled by the Southbound API (SB-API). However, such solutions do not focus on optimal information delivery to the orchestrator, a crucial property to provide prompt feedback in response to network events, and to potentially drive self-healing and autoscaling properties. To address such need, we present NOTORIETY, an orchestration system that provides an abstraction for real-time SDN network controller event message handling. NOTORIETY is able to maximize the orchestration capabilities of SDN controllers including innovative features for processing and delivering network event information. NOTORIETY's design consists of mechanisms that empower SDNcontrolled entities by applying filtering rules to efficiently control and optimize data flows provided by the SDN controller. We implemented a testbed to assess our NOTORIETY proposal following the guidelines provided in the RFC 8456, and we benchmark its performance over three SDN controllers (OpenDaylight, ONOS, and Floodlight). The evaluation results reveal the effectiveness of NOTORIETY in reducing the execution time of SDN requests, load processing, and overall data marshaling volume in several scenarios.

“…It is a well-known abstraction of underlying layer of hardware based on totally isolation. With the help of hypervisors, multiple virtual machines can be easily provisioned to form an HPC cluster on the top of individual or group of physical servers with limited performance but with higher security [4]. Each individual virtual machine is considered to have its own execution environment to execute the multiple parallel processes in terms of operating system with well-defined computing resources [5].…”

Virtualization is playing as a core component in cloud computing but performance overhead impact in its one of layer is forcing the researchers to think its usage in research areas with cloud for high performance computing. Where containers usage based on operating system virtualization widespread now a days is handling the performance impact via facilitating one of the lightweight layers of virtualization in terms of computing resources such as network bandwidth, throughput, CPU, memory at a large extent. Docker is one of the popular containerized platforms to be used in cloud computing and high-performance computing research areas. In this paper, we are proposing a basic strategy to avoid the performance impact and feasibility using Docker engine along with its evaluation in terms of containers vs virtual machine. Later, we have described the containerized placement now a days and performance specific problems resolution using container images for the development and deployment of HPC applications. The results and related work are focusing on a scalable approach in terms of availability and portability.

Cloud computing is a paradigm which is providing rent based service for the on-demand request for cloud users. It reduces a large amount of investment for many organizations. Cloud environment plays a vital role in minimizing management effort for computational, storage of data, and other services. Cloud environment facilitates anything as a service for consumers. Many organizations move towards cloud computing environment for outsourcing their business through the internet at the same time major issues are available in different service levels. Many types of research are going on in different levels. One of the major issues is security and privacy. This paper presents a review of issues in cloud and summarizes security and privacy related issues and also discusses different techniques used for securing the cloud. The motivation of this paper is to provide some useful background information for organizations considering the cloud computing environment to take advantage of this new computing paradigm.
