    Opis:
    The paper describes the concept and the design process of a software-defined computer built for didactic purposes and as a proof-of-concept. The computer uses a classic microprocessor from the 1980s with all of its other components – memory, I/O, supplementary glue logic and a hardware bus monitor implemented with a contemporary mainstream microcontroller with Cortex-M family core. The concept of a software-defined computer was successfully implemented with four significantly different microprocessors. The computer may be used for illustrating the operation of a processor and for teaching the basics of low-level programming. It is also capable of running CP/M operating system. Its operation is controlled at both hardware and software level from a PC via two instances of a terminal emulator software.

    Opis:
    : In the paper, the authors present a method of anomalies detection and identification in network traffic using statistical signatures. There is also shown a new system architecture based on the Software-Defined Networking (SDN) which allows for application of statistical anomaly detection in computer networks. With the proposed hardware-software model, it becomes possible to implement custom algorithms for the threats detection with the use of recognized and secure communications standards. The proposed architecture has been built based on an open-source solutions and can be used directly in production environments.

    Opis:
    The number of data centers (DCs) used for storing and processing data has evolved rapidly in recent years. However, the operations held by DCs may relate to a number of disadvantages, primarily presuming in excessive energy and power consumption due to the poor management standards applied. This may lead to a situation in which many devices within the DC operate at full capacity without any tasks assigned for actual execution. A Software Defined Network (SDN) is a network architecture where the control plane is an independent entity from the data plane, yielding to a higher controllability and flexibility over the network. Through the utilization of SDN architecture, a highly functional energy aware network may be established. In this paper, we propose a heuristic algorithm that monitors the current status of an SDN network (in addition to all ingoing and outgoing traffic), in order to dynamically and efficiently allocate network resources by ensuring that only the necessary network devices are active and by turning the idle ones off. The results show that the proposed algorithm reduces energy consumption of the network compared to existing solutions.

    Opis:
    The article refers to the idea of using the software defined network (SDN) as an effective hardware and software platform enabling the creation and dynamic management of distributed ICT infrastructure supporting the rapid prototyping process. The authors proposed a new layered reference model remote distributed rapid prototyping that allows the development of heterogeneous, open systems of rapid prototyping in a distributed environment. Next, the implementation of this model was presented in which the functioning of the bottom layers of the model is based on the SDN architecture. Laboratory tests were carried out for this implementation which allowed to verify the proposed model in the real environment, as well as determine its potential and possibilities for further development. Thus, the approach described in the paper may contribute to the development and improvement of the efficiency of rapid prototyping processes which individual components are located in remote industrial, research and development units. Thanks to this, it will be possible to better integrate production processes as well as optimize the costs associated with prototyping. The proposed solution is also a response in this regard to the needs of industry 4.0 in the area of creating scalable, controllable and reliable platforms.
