Bandwidth resource allocation method and device based on communication requirements

The embodiment of the invention discloses a bandwidth resource allocation method and device based on communication requirements, equipment and a storage medium. The method comprises the following steps: acquiring at least one communication application of at least one node equipment hung on a high-speed industrial control bus, wherein the communication application comprises a service type, a real-time requirement and a required bandwidth size; performing priority ranking on the communication applications of the node equipment according to a preset ranking rule; and allocating bandwidth resources matched with the communication application to each node device according to a priority ranking result. According to the technical scheme provided by the embodiment of the invention, each communication application is subjected to priority ranking according to the service type, the real-time requirement and the size of the required bandwidth, and the bandwidth resources are distributed to each communication application i
