Embodiment 2

[0042] Refer figure 1 , A large-scale, high merged deterministic network system such as figure 1 As shown, network redundancy mechanism, system partition policy, synchronous clock control mechanism, and transmission scheduling strategy.

[0043] Network redundancy mechanism: In some key security applications, since there is no redundancy mechanism, once some nodes fails, the communication interruption of the entire system will cause unpredictable consequences to determine the network, using network redundancy The balance mechanism can ensure that the application can communicate properly in some nodes to communicate normally to ensure a certain robustness.

[0044] Network redundancy mechanism takes three methods:

[0045] 1) When the timeout monitoring method is used, the fault timeout monitoring clock is set in the system. Once the monitoring clock is timeout, the fault model that occurs in the network is determined by the excess time as the judgment criteria, and the correspondi...

Abstract

The invention discloses a large-scale, highly concurrent deterministic network system, which belongs to the technical field of network communication systems, including a network redundancy system, a system partition strategy system, a synchronous clock control system and a transmission scheduling strategy system; the network The redundant system ensures network reliability through fault monitoring and rate control; the system partition strategy system is used for isolation control of business traffic, improving the scale and concurrency of the network; the synchronous clock control system provides a clock reference for the determinism of the network , which is used to ensure the synchronization of local clocks of global network devices; the transmission scheduling policy system generates a scheduling optimization policy through priority configuration, which is used to rationally use network bandwidth resources, improve message concurrency, and expand network scale at the same time.

Description

Technical field [0001] The present invention belongs to the technical field of network communication system, and specific to a large, high merged deterministic network system. Background technique [0002] The deterministic network is used in the field of industrial control, aviation airborne network, and military communication, etc. With a particular application, the determined network topology and protocol configuration completes the data transmission of the flow to the data and the purpose of data and resource interconnection. However, with the increasing maturation of the network technology and the size of network data, as the deterministic network is constantly improving, information transmission needs further broadband and diverse. For example, a new application function of large aircraft (such as large-screen display, digital map, air data chain, etc.) makes a higher demand for network data transmission. Therefore, deterministic network integrity issues are also more conce...
