ABSTRACT:
A packet processing method using a multiple fault tolerant network structure capable of performing communication of a whole ring and disusing a useless packet when a fault occurs on a plurality of connection lines and nodes by using a dual ring structure. Nodes are connected as a ring shape separately having two input lines and two output lines, and each node selects one packet after receiving two inputs and disuses the other packet and transmits the select packet through the two output lines at the same time. The present invention can solve the fault problem occurred on a multiple link or nodes, can perform network function efficiently by disusing a useless packet, accordingly it is possible to perform stable operation for several years or several decades after the network installation and decrease maintenance expenses.
