Method for configuring and managing TSN network and system applying the method
View Patent ↗In a method for configuring and managing a Time Sensitive Networking (TSN) network, a network packet is regularly captured and parameters are extracted. The parameters are submitted to a distributed learning model for matching an application according to the parameters, and a network requirement of the application is obtained.
