Method and node for determining transmission path of information

The present invention provides a method and a node for determining a transmission path of information. The method comprises: determining a type of a current node according to a location relationship between the current node and a fault ring; determining, according to the type, a next-hop node for transmitting information; and transmitting the information to the next-hop node. Therefore, in a communication process, an optimized fault-tolerant transmission path can be determined, thereby reducing link resources and ensuring real-time effectiveness of communication.
