Abstract
A method of time synchronization between a DS-TT module inside a logical TSN bridge of a communication network with a TSN Grandmaster (GM) in a TSN Time Domain of the communication network. The method comprises, at a NW-TT module inside the logical TSN bridge, determining a frequency rate ratio between a Time Domain clock frequency (f) and a TSN Time Domain clock frequency (f). Then, using the frequency rate ratio and respective times of receipt of a TSN GM synchronization message at an ingress port of the NW-TT module and at an ingress port of the DS-TT module to determine a DS-TT ingress residence time (R). Then, using the Rto synchronize the DS-TT module with the TSN GM.
