NETWORK RESTORATION METHOD AND APPARATUS

摘要

PURPOSE: A network restoration method and a device thereof are provided to save resources by transmitting a control message for alarming the generation of errors once. CONSTITUTION: A link error monitoring unit of a second switch senses errors between the second switch and a third switch(S300). After a message setting unit of the second switch sets a control message, the transceiver of the second switch transmits the set control message to a sixth switch(S310,S320). The sixth switch transmits data packets received from a fifth switch through a B link to the third switch of an A link and a seventh switch of the B link(S330). A communication unit of the second switch transmits error contents to a management server(S340).
