FIELD: radio engineering, communication.
SUBSTANCE: path management method includes stages for receiving a type-length-value (TLV) of an explicit path (EP) through a routing protocol based on communication channel state, the shortest path search algorithm is executed to obtain the shortest path for free path links, wherein this shortest path becomes the primary path, and the network graph is updated to cut-off the links of the primary path or to deflect the links of the primary path, and the reserve path is calculated using the algorithm of the shortest path search on the updated network graph.
EFFECT: maintaining automatic establishment of redundant paths and recovery in the packet switched network.
