Recently, a micro-service architecture has been adopted to an edge device in smart factory due to its maintainability and scalability. In the architecture, all services are generally implemented as Docker containers and deployed by Docker APIs which might be harsh to a factory operator. In this paper, we propose an easy-to-use web-based service deployment method for containerized service to in-factory...
Fraud prevention in the banking sphere is a very important type of activity which can cover a whole range of fraud schemes — both from employees and customers. The article studies the existing technologies for realization of the system of security control over functioning of POS networks in real time and analyzes them in detail. Besides, the concept of the system of monitoring and analysis of threats...
Mobile Broadband (MBB) Networks are evolving at a fast pace, with technology enhancements that promise drastic improvements in capacity, connectivity, coverage, i.e., better performance in general. But how to measure the actual performance of a MBB solution? In this paper, we present our experience in running the simplest of the performance test: "speedtest-like" measurements to estimate...
With the growing popularity of Internet of Things (IoT) services being applied in several aspects of real-life applications, performance has become an important requirement. Meanwhile, the techniques for reliability enhancement such as virtual machine migration and recovery also have significant impact on end-to-end performance. This paper proposes a predictive approach of reliability-aware performance...
This paper focuses on research device management mechanisms such as routers and switches, based on the NETCONF protocol, considered user authentication mechanisms using RADIUS-server and implementation of these mechanisms in currently being developed Eltex Network OS. Reflected the main features of NETCONF protocol — Network Configuration Protocol, produced theoretical and experimental comparison...
NVMe is emerging as the standard protocol for communicating with high performance storage devices over the PCIe interface, independent of the underlying storage technology. Being a relatively new standard, there is a distinct lack of tools that can help in evaluating contemporary and future storage solutions built on NVMe. In this paper, we provide the design and analysis of FlexDrive, a software...
We present a platform that enables a service drone to guarantee reliability for mission completion and to update an application while in flight, using a robot operating system (ROS). The ROS is a flexible framework for writing robot software. It is a collection of tools, libraries, and conventions that aim to simplify the task of creating complex and robust robot behavior across a wide variety of...
NAND flash is seeing increasing adoption in the data center because of its orders of magnitude lower latency and higher bandwidth compared to hard disks. However, flash performance is often degraded by (i) inefficient storage I/O stack that hides flash characteristics under Flash Translation Layer (FTL), and (ii) long latency network protocols for distributed storage. In this paper, we propose a minimalistic...
Many IoT applications consist of two types of actions: interaction with the device, which can be sensors or actuators, and interaction with the data, for example, to reveal insights. In this poster, we introduce a software stack that provides these functionalities in a scalable manner. The API for device interaction is designed with generality in mind so that widest possible array of devices are supported...
The fast development of Internet of Things (IoT) and cyber-physical systems (CPS) has triggered a large demand of smart devices which are loaded with sensors collecting information from their surroundings, processing it and relaying it to remote locations for further analysis. The wide deployment of IoT devices and the pressure of time to market of device development have raised security and privacy...
In the Software Defined Network (SDN) ecosystem, the controller remains the cornerstone of the architecture and the critical point of its success. That is why performance concerns have existed throughout the history of SDN and controller development. This paper aims at making a reality check on the current performance achieved by mainstream open source controllers. The measurements are carried out...
Current I/O devices communicate based on the PCIe protocol, and by default, all the traffic passes through the CPU-memory complex. However, this approach causes bottleneck in system throughput, which increases latency and power as the CPU processes device specific protocols to move data between I/O devices. This paper examines the cost of this centralized I/O approach and proposes a new method to...
This stage manage system is designed specifically for the integrated-control console of visual-effect equipment. System architecture, functional implementation and technical solution are proposed detailedly in this paper. This system is established based on C/S framework. Data transmission between the stage management console of visual-effect equipment and the integrated-control system is implemented...
Hadoop and Map reduce today are facing huge amounts of data and are moving towards ubiquitous for big data storage and processing. Benchmarking tools available are not capable of analyzing performance of the Hadoop cluster system and are made to either run in a single node system. HiBench is an essential part of Hadoop. It is a comprehensive benchmark suit that consists of a complete deposit of Hadoop...
Since increasing complexity and scale of modern software products imposes tight scheduling and resource allocations on software development projects, a project manager must carefully triage bugs to determine which bug should be necessarily fixed before shipping. Although in the field of Mining Software Repositories (MSR) there are many promising approaches to predicting, localizing, and triaging bugs,...
A multi-version concurrent control (MVCC) is widely spread as an important scheme to ensure the data integrity even in on-line storage services such as Dropbox as well as database management system. The scheme of MVCC is to make a snapshot of the current data before access to the data, and to compare the snapshot with the original data just before the update is committed. This discipline is called...
IEC 61850 is one of the crucial standards within the Smart Grid concept. For performance evaluation of communications between Intelligent Electronic Devices (IED) in Power Utility Automation, the standard defines the Transfer Time. Measurement of such parameter is not available for end user, but in development stage it is possible. Third party products can be used to reduce development time of IEC...
As community networks are being deployed more often, interest in using them as testbeds is growing too. Frameworks like the cOntrol and Management Framework (OMF) are helpful software tools to organize, control and instrument the testbeds deployed on those networks. However, community networks have a very heterogeneous infrastructure in which less powerful, embedded devices will play an important...
Network virtualization in cloud computing environment has attracted many attentions recently. With the help of network virtualization, VMM is able to provide fine-grained isolation among different VMs. However, the performance and overhead introduced by network virtualization is also important concerns when applying network virtualization to the cloud computing environment. In this paper, we evaluated...
Many protocols and communication standard appear in the Substation Automation System (SAS) world. Advanced communication standards a low the exchange of peer to peer information between primary devices in order to accomplish distributed automation application inside SAS. Evaluating the conformity of primary devices towards security and SAS architectures towards required specifications is a non trivial...
