Abstract

The invention belongs to the technical field of embedded system modeling, and relates to a network modeling method suitable for an embedded system. In order to realize network modeling, firstly, a network element model needs to be established; Specific steps are as follows: carrying out related modeling feature extraction on the AS6802; establishing sub-models of all parts of the time-triggered Ethernet meta-model by modules; namely, firstly, establishing a time-triggered Ethernet main element overview map; establishing a time-triggered Ethernet scheduling resource sub-model, establishing a frame classification sub-model, establishing a scheduling sub-model of a scheduler, establishing a partitioning system sub-model, and integrating the sub-models to obtain a time-triggered Ethernet overall sub-model capable of completing time-triggered network modeling. Based on the meta-model, network modeling can be carried out on the embedded system. According to the method based on the model, thedevelopment efficiency of the embedded software is improved, the labor cost is saved, and model drive development is enriched.

Description

technical field [0001] The invention belongs to the technical field of modeling of embedded avionics systems, and in particular relates to a network modeling method, device and storage medium suitable for embedded systems. Background technique [0002] Time-triggered Ethernet extends the event-triggered service of IEEE802.3, and establishes a system-wide time base through clock synchronization of end systems and switches, which results in bounded delay and low jitter, and integrates time-triggered on the same physical network and event triggers. The network limits the delay and jitter of TT traffic, limits the delay of RC traffic, and supports IEEE802.3 BE traffic service. This allows Ethernet to act as a unified network infrastructure, so it supports the deployment of mixed-criticality applications at the network level. Contents of the invention [0003] Purpose of the present invention: [0004] In order to solve the problem that the existing standard architecture and...
