Improvement and Implement of Communication schedule algorithm Base on EPA

摘要：

Through analyzing the characteristics of EPA (Ethernet for plant automation) Deterministic Communication Scheduling, this paper proposes a dynamic priority scheduling strategy, using dynamic priority upgrade mechanism so that the priority of the packet waiting time changes with the dynamic changes, and designs a dynamic priority scheduling algorithm, communication scheduling control algorithm and combined with slot scheduling algorithm to achieve the function of EPA Communication Scheduling. This paper improved EPA communication scheduling algorithm on the basis of it, combined with EPA protocol stack that the method can effectively solve the non-periodic low-priority packet transfer delay bigger problem.
