What is TAN ? Industry communication requirement Must be Time Sensitive Network？ Key 1： Deterministic and nondeterministic Integration Key 2：System synergy What is TAN ? Key 3：Network Robustness Key 4：Network Observability Key5：Network Security

What is TAN(Time Aware Network) Using an example, If you drive a car on a road, the legacy Ethernet tagged car only, but TAN tagged both car and road with synchronized clock. The network achieved by this method is called TAN. TAN where come from TAN(Time Aware Network) is a time-oriented industry communication technology. Time Aware Network is more than time synchronization. TAN born from Ethernet, renovated from Ethernet, and fully compatible with Ethernet. Time Aware Network has three key features: 1. Time aware of network The time of entire network is synchronized 2. Time aware of network device Entire network devices is precisely synchronized 3. Time aware of data All data has precision time attribute .

TAN deliver network deterministic insensitive transportation & NENET Make Changes with TAN TAN deliver network deterministic insensitive transportation

TAN Deterministic transportation in TAN + TOCAT（ Time-Oriented Control Automation Technology） + control instruction target time Random deliver in cycle deliver data by cycle control software operating system controlled device TAN The legacy control system only deliver control instruction to the controlled device. TAN not only deliver the control instruction, but also the target time for the controlled device to take action. Since the clock of TAN is synchronized, the controlled device can take action at any target time. In this regard, TAN is not only a network for data transportation, but also a global timing controller.

It's NOT important that the network is Time Sensitive Network. TAN jitter test result in the lab 800M(Mega) data traffic in the network jitter<500ns It's NOT important that the network is Time Sensitive Network.

Low latency transportation in TAN Source Destination Interfering data 1 3 2 4 5 6 2.1us 0.8us Achievement network delay per hop for real-time channel: 0.8~3µs Multi-channel structure,network determinism is guarteed Per channel is prioritized and pre-emption mechanism is supported .Higher priority channel could interrupt the lower priority traffic , and afterwards resume disrupted traffic, so lower latency is guaranteed for higher priority traffic.

System synergy TOCAT（ Time-Oriented Control Automation Technology） + control instruction target time Random deliver in cycle deliver data by cycle control software system A controlled device TAN system N contolled device -N t system A system N 500us 1000us 1500us 600us Different systems on the network can achieve system synergy by TOCAT 1200us 1800us

Synchronization of multi-axis & NENET & NENET Make Changes with TOCAT Synchronization of multi-axis

TAN Synchronization of multi-axis + Multiple Sampling Commands control system + sampling t1 TAN t1 time sample sample sample sample sample sampling Simultaneously servo motor 1 servo motor 2 servo motor 3 servo motor 4 servo motor n Since the clock of servo motor on TAN is synchronized, Servo motor 1,2,,N can take sampling simultaneously with the unique reference clock. Or take actions in the same way. The synchronization of multi-axis design is much simplified compared with the legacy method. TAN can achieve multiple-axis synchroniztion control, with unlimited number of axis. data transfer from source to destination is determined.

& NENET Robustness in TAN

Any network topology at layer 2 Legacy Layer 2 topology The TAN network can do more

Any network topology at layer 2 If you need,the TAN topology can be like this

Any network topology, without pre-configuration (Loop-free design) Achievement T The TAN support any network topology as you can ever imagined.The real “WEB” design at your hand The TAN network management can scan the whole network and gives you the real topology. With this feature, in field application, we need only electricians not IT engineers. All layer 2 Seamless redundency Loop-free No pre-configuration TAN technology support network topology as you never imagined

Multi-path transportation seamless redundency is achieved Achievement The TAN network will intelligently calculate the LEAST EFFECTIVE AREA(LEA) of communication and select multiple paths for traffic within selected area(LEA).The LEA is dynamic for traffic of different network access.Traffic is “always” confined within LEA. Multi-path communication possibles fault-free network which significantly enhance network robustness. The “LEAST EFFECTIVE AREA” rule is designed in with maximum 4 optimized paths are dynanically auto configured

Network Observability & NENET Time aware of data Network Observability

TAN Network Observability Achievement The legacy IT technology use port mirroring only, But TAN can do the entire network scanning as you desired: 1.Topology and topology changes are visible 2. All data with network access time and network delay is visible. 3. Accurate observation is achieved. 4. Accurate data path is observed. TAN Device A Observation Device C Device B Device D DATA Direction Access Time Network Dlay hello..

Secured TAN A New Method of Network Security & NENET Network Security in TAN Secured TAN A New Method of Network Security

Network Security Achievement The communication model is easily obtained as TAN provide a transparent network with time features , thus potential network attack can be discovered at early stage. IT has matured protection methods for threats that are known; but how can we prevent Industry from the unknown attack ? TAN provides a unique protection scheme for the unknown attack.
