Abstract

Abstract:

With the coming of the era of industrial internet,the data flow in the industrial scene is increasing exponentially.Time-sensitive network has become one of the important evolution directions of industrial network.By analyzing the challenges and development trend of new industrial networks,the necessity of time-sensitive network as its evolution direction was deduced.The core characteristics and mechanism of time-sensitive network were described,and the technical advantages of time-sensitive network were clarified,through the summary of the key capabilities of time-sensitive network were summarized,and the feasibility of time-sensitive network technology becoming the core key technology of new industrial network of industrial internet was further proved.

Key words: industrial internet, time-sensitive network, time-synchronization, traffic schedule
