The method comprises the following steps: adding feature data at the head of a source message through an access switch, wherein the message N (Ngt; 1 natural number) is sent, and a receiving end discards N-1 redundant data. A transformer substation network switch sends universal messages with feature data to N ports of a single-ring network at the same time, a receiving switch discards repeated late arrival messages, and message headers are analyzed through an agreed feature data format. And the substation network switch configures multicast address forwarding in a static mode, and discards messages which are not in a configuration range. A hot backup topology of star network core exchange between communication devices is configured by adopting an SPHPR principle, and parallel redundant hot backup of a core gigabit switch is realized by utilizing ...
