Abstract

The invention belongs to the technical field of embedded system modeling, and relates to a network modeling method suitable for embedded systems. In order to realize network modeling, it is first necessary to establish a network meta-model. The specific steps are as follows: extract relevant modeling features of AS6802, establish sub-models of each part of the time-triggered Ethernet meta-model by module, first create an overview of the main elements of time-triggered Ethernet, establish a sub-model of time-triggered Ethernet scheduling resources, and establish frame classification Sub-model, establish the scheduling sub-model of the scheduler, establish the partitioned system sub-metamodel, and then integrate the sub-models to obtain the time-triggered Ethernet overall meta-model that can complete the time-triggered network modeling. Based on this meta-model, network modeling of embedded systems can be carried out. The model-based method of the invention improves the development efficiency of embedded software, saves manpower costs, and enriches model-driven development.

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 The event-triggered service of TMZ 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 and event-triggered on the same physical network. The network limits the delay and jitter of TT traffic, limits the delay of RC traffic, and supports 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 analytical m...
