COMBINATION OF TRANSPORT PROTOCOLS AND SWITCHING PRINCIPLES AT THE BACKBONE LEVEL OF THE NETWORK INFRASTRUCTURE OF THE DIGITAL ECONOMY
T.P. Sergeeva, FSUE ZNIIS, chief researcher, Ph. D; tsergeeva@zniis.ru
The article discusses the construction of a promising backbone transport network (backbone), on the basis of which the backbone level of the network infrastructure of the digital economy is built. The analysis of the existing MPLS technology indicates its disadvantages, which do not allow using it as a packet transport of service networks. Some new packet transport technologies are presented. Among them MPLS-TP technology was chosen for further use with the organization of switched two-way channels with client traffic. It allowed to carry out the management and monitoring of the network in the «point-to-point» mode. The article provides a list of the main advantages of this technology, including the possibility of direct transfer of MPLS-TP channels in containers of the optical transport network.
Keywords: transport network, network infrastructure, VPLS, MPLS-TP, P-OTN.

The issues of ensuring and use of D2D communications, taking into account the density of subscriber devices, which are potential sources of interference are considered. The model for estimating the power of the interference signal at the receiving point on the basis of IEEE 802.11 family standards is constructed. It is shown that at the lower density of subscriber devices, D2D's capabilities significantly increase in terms of providing quality of service and communication range. The proposed analytical models can be used to estimate the level of interference at the known density of subscribers and the intensity of the load.
Keywords: wireless network, IEEE 802.11, signal noise ratio, signal interference ratio, interference, attenuation, quality of service.
