An Ethernet network protocol based on clock fault-tolerant synchronization and data fault-tolerant transmission
With the rise of the industrial Internet of Things,industry,electric power,petrochemical,railway transportation and other fields put forward higher requirements for the real-time and reliability of traditional Ethernet,so deterministic networks came in-to being.Deterministic networks are used to provide real-time data transmission to ensure that the quality of communication services can have the characteristics of ultra-low latency,low jitter,high bandwidth,and high reliability.Based on ISO/IEC/IEEE 8802-3,this paper proposes an Ethernet network protocol based on clock fault-tolerant synchronization and data fault-tolerant transmission,namely the TAN protocol.While the TAN protocol is compatible with"Ethernet"technology,TAN technology takes"time"as the core,defines a new type of data encapsulation and routing and forwarding technology,which can realize"high-precision clock syn-chronization"of all nodes and clarify the data time under large-scale networking conditions,break the restrictions on networking methods with"data multi-path transmission"technology,improve network reliability,realize real-time transmission of data with"multi-channel"preemption technology,and"software-defined network delay"The technology addresses the need for low-jitter transmission for periodic and(acyclical)communications.At present,TAN products have been applied in industry,electric power,petrochemical,railway transportation and other fields.
