Tikhonov V. Theoretical foundations of dynamic digital flow control based on the telecommunications complex tensor models

Object: digital streams control processes in wired telecommunication networks. Aim: theoretical foundation of digital streams dynamic control via the complex tensor models for efficient transmission of variety types of traffic in packet-based networks. Scientific novelty and practical significance: firstly proposed three-tier model for open system interconnection which simplifies inter-layer interaction; firstly proposed method for dynamic structuring control of sequential digital channel based on two-dimensional scale of service types which limits the packet transmission delay and reduces the cost of transferring voice traffic; firstly developed method of dynamic control of character encoding in optical coherent channel that limits the signal spectrum and increases the spectral efficiency of the channel; firstly introduced method of dynamic addressing with variable address length, that enables the address space expansion without changing the basic protocols and reduces overhead information; firstly presented the method of digital streams dynamic switching via the commands of variable length, which limits time delays, reduces data transfer costs and increases the information channel efficiency; enhanced the tensor method for digital flow control in the complex functional space, the mathematical model of optical signals interference on the coherent detector along with the inverse problem regularization method for the modulated optical signal estimation. The results implemented in the DP "NDI MP", in PAT "Ukrtelecom", in A.S. Popov ONAT. Made an information contribution to ITU. Registered 6 patents of Ukraine and 3 copyright certificates.
