METHOD AND SYSTEM OF PROTECTION IN TIME SENSITIVE NETWORKS OF A RING TOPOLOGY OF RING TOPOLOGY

摘要

A protection switching method in a time sensitive network of a ring topology consisting of layer 2 switch-based nodes includes ranging to measure a first delay until a packet arrives at each node, RT, after transmitted by the main node OT via a path of a first direction and a second delay via a path of a second direction, performing a transmission delay compensation in the first direction or in the second direction based on the first and second delays, transmitting data to one direction of the first direction and the second direction based on the delay compensation, and performing a protection switching and compensating by performing the protection switching and compensation based on the measured delay after the switchover.
