Abstract

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.

- across segments transmission,
- filtering rule of message,
- time-base difference,
- transmission delay
