Chapter
The aim of this contribution is to analyse practical aspects of the use of REST APIs and gRPC to realize communication tasks in applications in microservice-based ecosystems. On the basis of performed experiments, classes of communication tasks, for which given technology performs data transfer more efficiently, have been established. This, in turn...
Conference Paper
In this work, the development of virtual reality software for “industrial applications” is considered. It is argued that, in this context, the vast experience from the development of computer games cannot be used directly. Especially, the specific nature of solutions dedicated to industrial applications requires taking into account their specificit...

The paper focuses on the phenomenon of phase transitions related to changes taking place directly in a network structure; i.e., in physical topology. Although these changes are related to the physical layer, they directly affect the functioning of higher layers, and thus the quality and efficiency of network transmission. The research presented her...

Article
Examples of applications of the Industry 4.0 concept in manufacturing operations connected with processing of polymer materials were presented. Implementation of Industry 4.0 structure aims at increasing the speed of manufacturing with simultaneous decrease in the number of defective products. Such results are enabled by the use of integrated infor...
Chapter
The process of creating software for modeling and simulation of phenomena taking place in computer networks should take into account many aspects of their functioning. However, until now, the creation of such software was based on a reductionist approach. This approach is typical for simple or most complicated systems. In contrast, software for mod...

This article presents the use of the Link Aggregation Control Protocol (LACP) for detection of anomalies in network traffic. The idea itself is based on checking the representativeness of a single LACP link for the whole traffic transmitted by the aggregation. This approach allows to reduce the requirements for the performance of threat detection s...

Currently, IT systems require more and more reliability. It can be guaranteed only by using redundancy both in the connectivity and network devices. The authors attempted to measure the convergence time for EIGRP and OSPF routing protocols after link or network nodes failure. Research have been conducted with the real devices and hardware traffic g...
Article
Models describing the wireless network environment in most cases are based on the assumption that they are simple systems. However, the parameters describing this type of networks are particularly sensitive to the volatility of the operating conditions. Simple systems take only two operating states into account apart from an overload state, i.e. un...
