PROTECTION OF A HETEROGENEOUS TELECOMMUNICATION NETWORK FROM THE INFLUENCE OF DESTABILIZING FACTORS

Natural and anthropogenic hazards and their impact on a heterogeneous telecommunication network are analyzed. The currently existing telecommunication network protection measures have been analyzed. A heterogeneous network is considered, which consists of sections of communication lines with the transmission of signals of different physical nature over different transmission media. Communication lines react differently to threats, which allows you to choose the line with the best indicators for transmitting information. Examples of enhanced precautionary measures for the protection of underground line-cable structures are presented. A cause-and-effect diagram of events that determine the state of the information transmission network - changes in emergency/non-emergency time intervals - is presented. The scheme of application of protection measures against dangerous events is shown. To verify measures, a matrix of their compliance with typical natural disasters was developed and relevant examples were given. It is proposed to evaluate the flexibility of the telecommunications network by its connectivity, which is characterized by the numbers of vertex and edge connectivity, connectivity probability. An algorithm for calculating path connectivity has been built. The scheme of the device for carrying out multi-channel transmission of information in a hybrid network is presented, which allows the selection of the channel with the best indicators for the transmission of information. The general scheme of the operation of the intelligent block is proposed. A proposal has been put forward to increase the flexibility of the network, which consists in the use of this device. The article proposes to evaluate the flexibility of the telecommunications network by its connectivity. It is proposed to use machine learning in the management of a heterogeneous telecommunication network, which will allow predicting a destabilizing factor, its possible impact, and issue an algorithm for preventing the impact or solving the consequences of the impact.
