Title:
COMMUNICATION METHOD FOR REDUCING ASYMMETRY IN DUAL PATHS OF RING TOPOLOGY
Document Type and Number:
WIPO Patent Application WO/2020/222356
Kind Code:
A1
Abstract:
Provided is a communication method for reducing asymmetry in dual paths of a ring topology. A communication method for reducing asymmetry in dual paths of a ring topology according to an embodiment of the present invention comprises the steps of: on the basis of a dynamic property in a frame, determining a transmission scheme of the frame as a non-preemption scheme or a preemption scheme by each node constituting a ring topology; and transmitting the frame according to the determined transmission scheme. Accordingly, the present invention can reduce a transmission delay deviation between duplexed paths, thereby reducing possibility of occurrence of a sequence-switching phenomenon error due to asymmetry in a network.
