МОДЕЛЬ НАДЕЖНОСТИ ОПТИЧЕСКОЙ КОЛЬЦЕВОЙ СЕТИ С ВОЛНОВЫМ РАЗДЕЛЕНИЕМ

It is considered the possibility of construction of the high‑speed object local net based on new domestic highly efficient clustered on‑board computing platform on the basis of 64‑bit Elbrus (BC‑3416) processor with use of original high‑reliability physical environment. Increasing of the optical object local net reliability is ensured by automatic restoration of such net in the case of single break of communication link using dual‑redundant communication lines by wave lengths (wave compression) instead of fibers duplication as it was made in traditional nets. An analytical model is presented to assess the reliability indicators of the proposed fault‑tolerant fiber‑optic circular net with wave separation, wave channels redundancy and self‑recovery. Use of circular optic net allows to provide the symmetry of transmitting directions capacity, increasing of transmission speed with use of wave compression principle.
