HSR METHOD OF REDUCING IN HSR NETWORK BY USING ESTABLISHING DUAL PATH

摘要

The present invention relates to a method for reducing excess traffic in an HSR network using dual path generation and is performed in an HSR network including an HSR terminal node, a DANH node, a RedBox node, and a Quad-Box node, Searching and establishing a dual path which is a path between a transmitting quadbox node and a receiving quadbox node between HSR rings using a guard frame transmitted from the HSR terminal node and a dual path search message and a dual path response message ; And (b) forwarding the frame through the dual path established in the step (a) when transmitting the frame from the source node to the destination node. This improves the unicast traffic by 80-88% compared to the network using the existing HSR protocol, saves network bandwidth, and thereby improves network performance.
