摘要: 针对EPA网络只支持网段内的实时数据传输而不支持跨网段的实时数据传输问题，提出了一种EPA跨网段延迟自适应实时调度算法；分析了EPA跨网段数据传输过程，给出了EPA跨网段数据传输延迟模型；通过对EPA跨网传输报文的过滤规则的改变，以及对非周期数据声明报文的改造，实现了跨网数据的实时传输。

Abstract: In view of problem that EPA network only supports real-time data transmission inside segments but not across segments, a real-time adaptive scheduling algorithm for across segments delay in EPA was proposed. Transmission process of across segments in EPA was analyzed, data transmission delay modeling of across segments in EPA was given, and real-time data transmission of across segments was realized through change of filtering rule of across segments transmission message in EPA and transformation of statement message of aperiodic data.
