Package for data management of a telecommunication device in a monitoring system

In order to identify the role of data storage in the monitoring system of a telecommunications device, a conceptual design method was used, which was based on the basic principles of the Telecommunication Management Network concept, which is a network management system for telecommunication operators. Based on this concept, it was possible to design a data storage model in the monitoring system of a telecommunications device, which clearly reflects the separation of databases involved in the telecommunications network at different levels of the concept. A description of the differences between the databases assigned to each specific level from each other and an explanation of the functional features of each of the databases under consideration, as well as a description of the data circulation process over the network, is presented. The work focuses on describing the contents of the database of a specific telecommunications device, which is the object of control in the communication network, with the possibility of developing an interface to this database, which makes it convenient to search, view and modify stored data. To designate the information stored in the database of a telecommunications device, a fragment of the database was developed containing a set of attributes characterizing the device, their values and parameters of attribute values. The role of the database interface is to enable the user to quickly and easily access the information contained in the database.

Methods for assessing the impact of bandwidth of control channels on the quality of telecommunications networks in the transmission of data packets of different types

Abstract: It is known that since the early 2000s there has been a rapid increase in data traffic and a significant increase in the need for information flows in the process of providing new types of telecommunications services. This has led to the fact that the existing telecommunications networks have failed or approached the limit of their ability to serve subscribers with specified quality of service. The problem of improving the network architecture of such networks and improving the quality of their operation based on the use of modern methods and principles has arisen and needs constant solution. In this paper the requirements to the bandwidth of the channels of the telecommunication network management system in modern conditions are analyzed and their formalized description is given. In order to assess the bandwidth of the channel of the control network of the telecommunications network on the indicators of the quality of its work in the transmission of various types of data in the work developed and submitted an appropriate methodology.

Integration of security services in the architecture of telecommunications management systems

The main tasks of providing the security of the management system of telecommunication networks in Ukraine are considered. Standards and other regulatory documentation on information security of telecommunications and their management systems were analyzed. Special attention is paid to issues of security management as a component of the functional architecture of the telecommunications management system according to the concept of building a TMN telecommunications management network. The peculiarities of the implementation of security services for terminal or intermediate nodes of telecommunication networks are determined. The hierarchical model of providing security services is compared with the model of open systems interaction. A practical model of the security organization of the telecommunications network management system is proposed. The main advantages and disadvantages of the integration of security services at the lower and upper protocol levels are studied. The integration of security services and security mechanisms into the telecommunications architecture is determined by two main considerations: in which nodes should the security services be implemented; at what level each service should be implemented. Because there are a number of arguments for and against each of these levels, there is no single correct solution to this problem. It is advisable to find the optimal solution, depending on the specific security problem.

Design and Applications of GLANCE: GLanceable Alarm Notification for a User Centered Experience

The trade-off between awareness and interruption is a crucial aspect in network fault notifiers: Low severity alarms should not distract operators from other primary tasks, however it might be crucial that operators promptly react to critical notifications. A notification system should hence determine when a particular interruption is appropriate and how it should be presented. In this direction, this paper presents a multistep design path beginning from the objective of designing a proof-of-concept for a glanceable alarm notification component for telecommunication network management systems based on a peripheral display approach. In particular the goal was a notifier guided by severity-based strategies and offering the information expressiveness of a one-notification-at-the-time perspective while enriching it with overview capabilities to guarantee (possibly subliminal) long-term local and global content comprehension and prompt reaction only when the interruption from the foreground task is dictated by the fault severity. A first design macro-phase led to the simple yet effective GLANCE (GLanceable Alarm Notification for a User Centered Experience) model, based on a visual coding technique oriented to comprehension and reaction, and a transition strategy oriented to interruptions and reaction. A second design macro-phase studied the application of GLANCE to a personal customizable multichannel notification tool and to a service-oriented fault monitor for digital terrestrial television broadcasting networks.

Today, there are many standards that describe the architecture and mechanisms for monitoring and controlling elements of the Carrier Ethernet network, but there is no single methodology and requirements for the control system of such a communication network are not formed. This article proposes a solution to this problem by modeling the process of functioning of a telecommunication network based on this technology to manage its configuration. To create this model, the AnyLogic simulator was selected. The aim of the work is to identify the relationship between the reliability indicators of a telecommunication network based on Carrier Ethernet technology and the process of functioning of the telecommunication network management and recovery subsystems. As well as obtaining the dependence of the availability factor on the duration of the time between failures, the time of failure and on the quantitative characteristics of the configuration of the simulated network fragment. The multi-agent system, which is part of the control system, is in interaction with it. The use of a distributed telecommunications network control facility based on Carrier Ethernet technology at MASU will provide a demonstration of the dynamics of changes in the state of a fragment of a telecommunications network and obtain an estimate of network reliability. The solution to the problem of building the MASU model is based on the use of agent-based modeling, which belongs to the class of agent-based models. The paper uses the provisions of probability theory, control theory and system theory. The novelty of the presented model lies in the selection of a new Carrier Ethernet control object, the selection of an original set of control and management mechanisms for their inclusion in the model, and the use of the mathematical apparatus of agent modeling. Using the presented model to study the functioning of a telecommunication network allows you to track the behavior of each node and each route with its own failure and recovery rates for a network structure of any complexity, and allows you to solve problems associated with determining the length of time to lose connectivity in the route and the duration of the time between failures all routes simultaneously, allows you to form an assessment of network reliability and fault tolerance.

Determined that in modern science and technology, as well as in telecommunications in particular are widely used mathematical models of processes under study. The basic problem of determining the parameters of facilities management, including in particular is the task of the operator stochastic object that describes the relations hip between random input and output variables. This full common carrier, for example, multivariate conditional probability density of the vector output when monitoring the input vector. However, the definition of conditional distribution laws require sophisticated experiment and large volume calculations.

A Bayesian Argumentation Framework for Distributed Fault Diagnosis in Telecommunication Networks.

Traditionally, fault diagnosis in telecommunication network management is carried out by humans who use software support systems. The phenomenal growth in telecommunication networks has nonetheless triggered the interest in more autonomous approaches, capable of coping with emergent challenges such as the need to diagnose faults’ root causes under uncertainty in geographically-distributed environments, with restrictions on data privacy. In this paper, we present a framework for distributed fault diagnosis under uncertainty based on an argumentative framework for multi-agent systems. In our approach, agents collaborate to reach conclusions by arguing in unpredictable scenarios. The observations collected from the network are used to infer possible fault root causes using Bayesian networks as causal models for the diagnosis process. Hypotheses about those fault root causes are discussed by agents in an argumentative dialogue to achieve a reliable conclusion. During that dialogue, agents handle the uncertainty of the diagnosis process, taking care of keeping data privacy among them. The proposed approach is compared against existing alternatives using benchmark multi-domain datasets. Moreover, we include data collected from a previous fault diagnosis system running in a telecommunication network for one and a half years. Results show that the proposed approach is suitable for the motivational scenario.

The article analyzes existing approaches and methods for assessing the efficiency of a telecommunication network and its management system. The concept of efficiency, classification and existing approaches to its evaluation are considered. A number of indicators of telecommunication network efficiency characterizing the target, technical (technological), economic efficiency of the telecommunication network are given. The indicators of efficiency of the telecommunication network management system are considered. The method of estimation of efficiency of routing methods as a subsystem of routing management of a telecommunication network management system, which consists of seven stages, is presented. Indicators of the effectiveness of routing methods are considered as three groups of indicators, which are divided into global, local and operational financial. The efficiency of routing methods (by parameters of productivity, packet delay time) is given when changing the topology and different routing methods for fixed input load and network dimension. It is shown that the efficiency of the control system is determined by the efficiency of the telecommunication network.

A Novel Long Term Telecommunication Network Planning Framework

The design of large scale telecommunication networks is more than the technical allocation of capacity and path routing. By examining the design and allocation of resources in a broader sense, telecommunication network planning and management can better deliver value to the various stakeholders. This is significant especially when deploying networks in economically marginal areas such are rural, remote, or economically depressed regions. This paper presents a planning framework to systematically incorporate the influences, resources and decisions to effectively build or expand a network. Using a stake holders, input, process, output, customer approach, six key areas of society that derive value from better communication infrastructure in relatively unique manners were identified. These areas include healthcare, education, business, and others. The framework presented defines the inputs and outputs that accounts for the range of influences and outcomes in a network planning process. Inputs are broken down into four areas of concern (technical, market, financial, and application trends) that can influence how a network could be designed, along with four output areas (auxiliary activities, deployment strategies, technical design, and ownership and access). Through an extensive literature survey across many industries this framework was established to incorporate the many social economic and technical factors that influence telecommunication network planning and design.
