Abstract

The invention discloses a formalized analysis method for a scheduling and flow shaping mechanism of a time sensitive network. The method comprises the following steps: determining components of the TSN scheduling and flow shaping mechanism; abstracting a simple scheduling and flow shaping model according to the determined components; determining a refining scheme of the model according to the abstract model; and performing formalized analysis and time performance analysis on the refined model. According to the method, formalized modeling is carried out on the TSN scheduling and flow shaping mechanism, so that whether the final protocol standard meets the requirement of time sensitivity or not can be ensured through reasoning and verification, and the correctness and reliability of the protocol standard are ensured; moreover, the improvement cost of the abstract model is relatively low, certain help can be provided for development and subsequent expansion of protocol standards, and thedevelopment time and cost can be saved; and quantifiable indexes are provided to compare similarities, differences, advantages and disadvantages of different scheduling mechanisms.

Description

technical field [0001] The present invention relates to the field of software technology, in particular to a method for formally analyzing the scheduling and traffic shaping mechanism of Time-sensitive networking (TSN for short). Background technique [0002] Since the establishment of the TSN working group by the IEEE 802.1 task group in 2012, many standards have been developed to solve data communication problems in time-sensitive networks, and have attracted extensive attention from the industry and the automotive industry. With the continuous expansion of TSN standards, the TSN network environment naturally becomes more and more complex. Therefore, the security of the TSN network urgently needs to be guaranteed to ensure that it can provide accurate, punctual, and fast data communication, while also ensuring high reliability and bounded low latency. However, most of the current research methods use testing and simulation to study and analyze the scheduling and traffic s...
