METHOD FOR DETECTING COMMUNICATIONS ERRORS IN NODE IN DISTRIBUTED NETWORK SYSTEM

摘要

The present invention relates to a method for detecting a node in which a communications error has occurred in a distributed network system, more particularly, to a method for detecting, in real time, a node in which a communications error has occurred. According to an embodiment of the present invention, the method for detecting a communications errors in a node of a distributed network system, which has a plurality of slave nodes and a master node for managing the slave nodes, comprises a reference BCH code generation step in which the master node generates a BCH code for a basic code and stores the BCH code as a reference BCH code; a basic code transmission step in which the master node transmits the basic code to each slave node; a slave BCH code generation step in which each slave node generates a BCH code for the basic code and stores the BCH code as a slave BCH code; a slave BCH bit transmission step in which each slave node transmits a bit value in different position in bit strings of the slave BCH code to the master node as a slave BCH bit value; and an erroneous node detection step in which the master node compares the received slave BCH bit value and a bit value of the reference BCH code in the bit position corresponding to the received slave BCH bit value, and detects the slave node which has transmitted the slave BCH bit value as an erroneous node when the received slave BCH bit value and the bit value of the reference BCH code are not equal.;COPYRIGHT KIPO 2014;[Reference numerals] (100) Master node; (200) Slave node; (S200) Reference BCH code generation step; (S210) Transmitting a basic code; (S220) Generating a slave BCH code; (S230) Transmitting a slave BCH bit; (S240) Errorneous node detection step
