Packet scheduling method by using mixed-criticality mode in software-defined network system computer program therefor and switch apparatus therefor

摘要

The present invention relates to a packet scheduling method using a mixed-criticality mode in a software-defined network system, a computer program performing the method, and a switch device performing the method and, more specifically, to a packet scheduling method performed by applying a mixed-criticality (MC) mode to propose a new design and implementation by improving the conventional software-defined network system, a computer program performing the same, and a switch device performing the method. T present invention presents a method to solve the technical limitations of the conventional software-defined network to enable highly efficient adaptive real-time network flow scheduling in the Ethernet-based network, which will become the next-generation embedded network standard, thereby greatly improving the real time of the system. The present invention can be used as a base technology to efficiently use the internal network resources of complex cyber-physical systems (CPS), such as autonomous vehicles, which are attracting attention recently.
