METHOD FOR DYNAMIC RECONFIGURATION OF FIBER-OPTICAL COMMUNICATION NETWORK Russian patent published in 2023 - IPC H04W40/00 H04B10/27 

FIELD: optical systems.

SUBSTANCE: communication networks. The technical result is achieved by grouping network communication nodes into subnets, designing a ring structure in each subnet, defining a central communication node in each subnet, connecting all the central nodes of the subnets with each other by communication lines, defining auxiliary communication nodes in each subnet, connecting all auxiliary nodes subnetworks between each other by communication lines, measure the attenuation of the optical signal a_os in one-dimensional routes in each subnetwork, calculate the maximum allowable value of the attenuation of the optical signal a_add in each one-dimensional route, switch two independent multi-dimensional message transmission routes, transmit messages along the first multi-dimensional route, with an increase of attenuation of the optical signal in one or more one-dimensional routes are switched to the second multidimensional message transmission route, while the FOCN is reconfigured, for which the first multidimensional message transmission route is switched off, one-dimensional routes are excluded from it, in which a_os > a_add, after which the first multidimensional message path is re-switched from the remaining one-dimensional routes not included in the second multidimensional route.

EFFECT: increasing the survivability of a fiber-optic communication network (FOCN) by designing the FOCN structure and switching several independent multidimensional routes with minimal attenuation of the optical signal in them.
