Distributed Denial of Service (DDoS) attacks poses a severe threat to widely used internet-based services and applications. Currently, during in the technology era, the internet is the only real exigent that delivers a glut of services like businesses, banking, communication, education, e-commerce, etc. Distributed Denial of Service attack aims to deny access by legitimate users to shared services or resources. Because of the vulnerability of the initial style of the web, attackers can merely mimic the patterns of legitimate network traffic. The prevailing fingerprint or feature-based methods are not appropriate to detect a recent DDoS attack. In this paper our goal is to detect a DDoS attack as well as Flash Crowd using various information distance measures such as Kullbeck-Leibler, Hellinger and Manhattan distance to measure the flow similarity among the traffic. Further the detection parameters such as Detection Rate, Classification Rate, Precision Rate and False Positive Rate is computed and shows that the Kullbeck-Leibler detection metric effectively detects the attack as compared to the other two.

The Cloud computing paradigm promoted the outsourcing of IT infrastructure and enterprise applications paving the way to save costs of building and maintaining computing infrastructures on-premise. In this environment, scale up of applications to attend demands in high peaks become easier and highly automated. Virtualization was a key technology to enable these characteristics. Nowadays, Container technology became popular as an alternative to Virtual Machines, and is being widely applied, as a consequence, Orchestration tools are being extensively applied in the Cloud environment. Despite its success, when it comes to the internet of Things (IoT), Cloud computing falls short to meet several requirements. Fog computing appear as a complimentary technology to the Cloud to deliver the missing requirements in the IoT scene. Managing services deployed in a Fog Environment is a complex task and infrastructure management and orchestration tools can make it seamless. In this paper, we evaluate how Containers can affect the overall performance of applications in Fog Nodes. We analyze different Container Orchestration tools and how they meet Fog requirements to run applications. We also propose a Container Orchestration Framework for Fog computing infrastructures.

internet of Things (IoT), one of the key elements of a smart factory, is dubbed as Industrial IoT (IIoT). Software defined networking is a technique that benefits network management in IIoT applications by providing network reconfigurability. In this way, controllers are integrated within the network to advertise routing rules dynamically based on network and link changes. We consider controllers within Wireless Sensor Networks (WSNs) for IIoT applications in such a way to provide reliability and timeliness. Network reliability is addressed for the case of node failure by considering multiple sinks and multiple controllers. Real-time requirements are implicitly applied by limiting the number of hops (maximum path-length) between sensors and sinks/controllers, and by confining the maximum workload on each sink/controller. Deployment planning of sinks should ensure that when a sink or controller fails, the network is still connected. In this paper, we target the challenge of placement of multiple sinks and controllers, while ensuring that each sensor node is covered by multiple sinks (k sinks) and multiple controllers (k' controllers). We evaluate the proposed algorithm using the benchmark GRASP-MSP through extensive experiments, and show that our approach outperforms the benchmark by lowering the total deployment cost by up to 24%. The reduction of the total deployment cost is fulfilled not only as the result of decreasing the number of required sinks and controllers but also selecting cost-effective sinks/controllers among all candidate sinks/controllers.

Intelligent industry and manufacturing requires obtaining relevant sensor data and process information in real-time from all components in the manufacturing value-chain. It is envisioned that smart industry is achieved by embedding connectivity into industrial products, using Cloud and internet-of-things (IoT) to leverage intelligence and actionable knowledge for machines, autonomous collaboration among machines, and integration of products and additional value-added services. For complex industrial systems, it is important to ensure a smooth transformation towards the smart industry vision despite of the associated challenges with respect to e.g., transition from the traditional multi-layered architecture to an open structured service-oriented automation system architecture, changes of business models and strategies, legacy system migration to cloud environment, etc. The focus of this study is therefore to examine the status of the existing research on cloud computing and IoT solutions that enable this transformation towards a smart industry. We applied the systematic mapping study method to obtain an overview of the existing related research literatures that focus on smart industry, industrial automation and manufacturing perspective. We also discuss the future research areas that need to be enhanced.

With the development of big data and cloud computing technology, the traditional software-defined network is facing new challenges (e.g., ubiquitous accessibility, higher bandwidth, more flexible management and greater security). This paper proposes a new service-oriented software defined optical network architecture, including a resource layer, a service abstract layer, a control layer and an application layer. We then dwell on the corresponding service providing method. Different service ID is used to identify the service a device can offer. Finally, we experimentally evaluate that proposed service providing method can be applied to transmit different services based on the service ID in the service-oriented software defined optical network.

With the growing popularity of the internet of Things (IoT), energy efficiency has been a critical concern during the design and development of IoT service systems. Meanwhile, edge computing has drawn significant attention as a burgeoning computing paradigm. This paper studies the energy efficiency issue of IoT systems by proposing a joint scheme of resource allocation and task scheduling under the edge computing paradigm. Specifically, dynamic processes of the IoT services and system are formulated by generalized queueing network models, based on which quantitative analyses of performance and energy consumption are conducted. The resource management and task scheduling are formulated by Markov Decision Process (MDP), which can balance the tradeoff between energy costs and QoS requirements. To attack the challenge of MDP search space explosion due to the large scale of IoT systems, Ordinal Optimization (OO) techniques are applied to the MDP algorithms, which are able to significantly narrow the search of MDP by slightly softening the optimization objective to a good enough subset. Finally, we conduct simulation experiments based on real-world IoT data. Evaluations and comparisons demonstrate that our approach is effective and efficient in practice.

in recent years, the rapid development of internet technology has radically changed people's work, learning and lifestyles. More and more activities are completed by virtue of computers and networks. The amount of information and data generated is bigger day by day, and people rely more on computer, which makes computing power of computer fail to meet demands of accuracy and rapidity from people. The cloud computing technology has experienced fast development, which is widely applied in the computer industry as a result of advantages of high precision, fast computing and easy usage. Moreover, it has become a focus in information research at present. In this paper, the development situations and trend of cloud computing shall be analyzed and researched.
