Chemical Mesoscopics Notions in the Explanation of Polymeric Materials Modification Mechanism with Participation of Metal Carbon Mesocomposites

The paper is dedicated to the consideration of the chemical mesoscopics notions application for the explanation of polymeric materials modification mechanism by the metal carbon mesoscopic composites. The main peculiarities of these nanosized particles are following: a) the presence of unpaired electrons on the carbon cover; b) the structure of carbon cover consists from poly acetylene and carbine fragments; c) the atomic magnetic moment of inner metal is equaled to more than 1,3 μB. The metal carbon mesocomposites activity depends on the medium and conditions influence because of the possible changes of the phase coherency and quantization of negative charges

Implementation of a Policer-Based Control Loop for the Dynamic Resource Allocation of a Software-Defined Communication Infrastructure

The use of solutions based on the principles of virtualization is designed to increase the efficiency of using the communication infrastructure due to the dynamic distribution of existing communication and computing resources between their virtual components. The software management of the communication infrastructure components opens up opportunities for applying new approaches to solving the currently very urgent problem of ensuring the required Quality of Service. Taking into account the current trends in the development of communication infrastructures and means of their automation, it seems relevant to build systems that implement a closed cycle of communication infrastructure resource management based on traditional and promising tools for monitoring and managing QoS and studying its behavior. Closing the control loop is achieved by implementing a control script that automatically responds to changes in the transmitted data and makes decisions about changing the current configuration of network devices. One of the approaches to building a closed control loop is to change the physical bandwidth of a virtual communication channel depending on the intensity of its resource use. The paper considers an example of the implementation of a closed control loop based on the rules of the policy for limiting the rate of sending packets of heterogeneous traffic and compares the approach of dynamic bandwidth redistribution with traditional approaches. © Published under licence by IOP Publishing Ltd

Deployment of Software-Controlled Distributed Laboratory Complex for a Higher Educational Institution

The intensive development of information systems and communication infrastructures has led to the emergence of new approaches and new tools for their management. Cloud services, virtualization technologies and software-based management tools are actively used today for building modern information systems which provides additional opportunities for managing components of these systems and for expanding such systems abilities. The use of such approaches and tools can provide a solution to the complex of problems faced by education institutions today, presenting new methods of distance learning and new forms of practical training. The balanced use of virtualization technologies and software-based control tools allows building distributed laboratory complexes of a new generation which will provide new possibilities for using the equipment that is available in educational institutions. The use of such complexes in the educational process allows not only to instill in students the skills of managing the configurations of communication infrastructures that are especially relevant today, but also to organize, in addition to traditional laboratory work, new forms of contactless practical classes. When conducting such classes, students get the opportunity to fully-functional remote access to the virtual and physical components of the complex, which is especially important for organizing the educational process in modern conditions associated with the COVID-19 pandemic. The article discusses modern approaches to the construction of software-controlled communication infrastructures, tools for software-based management of their components and also, an example of the implementation of these approaches and such tools usage in the construction of a distributed laboratory complex for a higher educational institution. The main advantages of the approach based on the use of hypervisors and emulators are presented, the experience of its deployment in the modernization of the laboratory complex for a IRIT-RTF UrFU is considered. © 2021 Institute of Physics Publishing.

Using NETCONF-proxy server to integrate laboratory equipment into software-defined infrastructures

The essential changes that have taken place over the past decade in the field of telecommunications present new requirements for the educational institutions laboratory complexes management. The modern management concept "Infrastructure as Code"(Infrastructure as Code, IaC) proclaims the usage of a single and universal approach for programmatic management of all components of the communication and computing infrastructure. One of the most common ways to implement this approach is based on the representation of managed unit's configurations in the form of specially marked-up records that form the configuration management database. In this case, process of infrastructure components control is nothing more then sequence of transactions that can be performed for this database records, both locally or remotely - by using network management protocols. The implementation of solutions based on modern universal protocols and network management tools will be complicated when the controlled components do not support modern network management protocols and are separated by the institution's intranet. As one of the possible approaches to solving these problems, we consider the use of gateway communication servers as part of the training classes, which will be able to implement dynamic configuration management of special laboratory equipment of the training class and to provide information interaction between the components of the laboratory complex. The paper considers the choice of control protocols for the gateway server, as well as tools for managing communication infrastructures, and presents an implementation option for this approach for integrating special laboratory equipment of the IRIT RTF at Ural Federal University laboratory classes into a single software-defined laboratory complex. © Published under licence by IOP Publishing Ltd
