The ring topology of the industrial network provide reliable performance and fast recovery time. It allows to provide redundancy in the fiber-optic links and to prevent various emergency situations. The transport layer of the ring has a speed of 10 Gbit/s. Network development is carried out from the ring with help industrial switches with redundancy protocols and fast recovery time with traffic 1 Gbit/s. Such equipment support protocols wich allow to build the ring topology, chain topology, star topology, redundant connections with automatic detection algorithms for backup and recovery network.
