Levels Of Service

We consider a general problem of optimal allocation of limited resources in a wireless telecommunication network. The users are divided into several different groups (or classes), which correspond to different levels of service. The network manager must satisfy these different users requirements. This approach leads to a convex optimization problem with balance and capacity constraints. We present several decomposition type methods to find a solution of this problem, which exploit its special features. We suggest to apply first the dual Lagrangian method with respect to the total capacity constraint, which gives the one-dimensional dual problem. However, calculation of the value of the dual cost function requires solution of several optimization problems. Our methods differ in approaches of solution of these auxiliary problems. We compare the performance of the suggested methods on several series of test problems. They show rather satisfactory convergence. Nevertheless, proper decomposition technique enhance the convergence essentially.

It is often necessary to determine statistical parameters that characterize the quality of service on the network by managing when designing computer networks using the concept of virtual connections with bypass directions.  In many ways, the attainable level of quality of the services provided is determined at the stage of network design, when decisions was made regarding the subscriber capacity of stations, the capacity of bundles of trunk lines, the composition and volume of telecommunication services provided. Despite constant progress in the field of network technologies, the problem of determining the necessary amount of network resources and ensuring the quality of user service remains relevant. In this regard, this article discusses a broadband digital network with service integration, based on an asynchronous network in which an iterative method implemented. Here the flow distribution is determined by the route matrix, and the load distribution between the nodes of each pair of nodes made through the path tree obtained on the matrix of routes when calculating this pair. At the same time, an algorithm has been built for allow optimal allocation of channel resources between circuit switching and packet switching subnets within an asynchronous network.

The problem statement: based on the analysis of the features of the development of modern public information and telecommunications networks (ITN), which consist in the geographical dispersion of network resources, sources and recipients of information; the pulsating nature of network traffic; heterogeneity of elements and applied network technologies; randomness of functioning; “intolerance” to management; the essential inconsistency of the main char-acteristics and the impossibility of a complete mathematical description, make it impossible to use the existing methods of control of the information and telecommunications system and the need to synthesize its subsystem of intellectual monitoring, as well as to develop new methods based on intelligent approaches. The purpose of the work is to provide synthesis of the subsystem of intelligent monitoring of the information and telecommunications network of the Ministry of Transport of the Russian Federation, as one of the key segments of the situation center of the department being created at the present time. Structuring of the controlled space by the terms “monitoring zone”, “critical element” and “technical condition classes” form the basis of a new approach to intelligent monitoring, regardless of the constant improvement (evolution) and heterogeneity of heterogeneous network infrastructures. The values obtained in the course of parametric synthesis of acceptable optimal values of the degree of loading of channels with measuring information make it possible to calculate the throughput of technological channels of tele-measurement-tele-signaling and the necessary amount of buffer memory with a known network topology and a given gravity matrix, providing the average minimum delivery time of intelligent agents (packets of measuring information) and the value of the maximum probability of failure in their service within acceptable limits. Based on the proposed hypergraph of the topological relationship of the monitoring zones of ITN of a household, the structure of its monitoring subsystem is constructed at the levels of fragmentation during the aggregation of controlled processes. The obtained results of the structural and parametric synthesis form the basis of the conceptual model of intelligent monitoring of ITN of the department

Multimodal Network

Basic services for power business were provided by the power multimodel network providers. However, because the power multimodal network is usually complex and changeable, the service of power business is often unstable. This problem can be solved by a suitable network resource optimization method. Therefore, how to design a network resource optimization method that seeks a compromise between multiple performance indicators that achieve the normal operation of power multimode networks is still extremely challenging. An optimal allocation method of power multimodal network resources based on NSGA-II was proposed by this paper. Firstly, the power multimodal network-resource model is established, and the problems existing in the resource optimization process are analyzed. Secondly, preprocessing technology and indirect coding technology are applied to NSGA-II, which solves the coding problem and convergence problem of the application of genetic algorithm to the optimization of network resource allocation. Finally, the simulation results show that, compared with the control algorithm, this method has further optimized the various indicators of the resource allocation of the power multimodal network, and the performance has been improved by more than 6%.

The Future

The trend of mobile networks 5G is growing with the increase in the number of users and the speed of transmission. Many operators are turning to small cellular and internal coverage of telecommunication network services. Due to the emergence of software-specific network technologies and virtualization of network functions, the ISP can deploy its networks more flexibly and dynamically. In addition to changing the model for deploying a wireless mobile network, it also determines the tendency for micro-operators to develop (μO). Communication operators can provide regional network services through public buildings, shopping malls or industrial facilities. In addition, localized network services are provided and bandwidth consumption is reduced. The distributed μO architecture meets the computing requirements for applications, data, and services from the cloud data center to the peripheral network devices or the micro-data center μO. The μO service model is able to reduce network latency in response to applications with a low latency for the future 5G boundary computing environment. This article discusses the design of the micro-operator 5G and proposes a mechanism for redirecting flows based on the decision tree (DTBFR) to redirect traffic flows to neighboring service nodes. The DTBFR mechanism allows different microcontrollers to share network resources and accelerate the development of border computing in the future.

An approach to determining the bandwidth of the self-healing segment of the data network is proposed. The subject of the study are autonomous segments of the telecommunications network, which have the property of self-healing. The object of research is the process of information transfer between nodes of an autonomous segment. The scientific novelty is to improve the method of determining the capacity of the self-healing segment of the telecommunications network with limited network resources by applying the criterion of ensuring the minimum time of information delivery at a given limit of possible probability of loss. The following tasks were solved: a mathematical model of the self-healing segment of the telecommunication network in the form of a queuing system was developed; the proposed method of calculating the degree of channel congestion. Conclusion: the proposed approach made it possible to calculate the bandwidth of the communication channels of the self-healing segment of the telecommunications network and the required amount of buffer memory with a known network topology and a given gravity matrix, providing the required values of failure probability and guarantee minimum message delivery time.
