基于多链路分组技术的AFDX网络延迟

Latency in AFDX Based on Multi-link Group Technology

应用网络演算(Network Calculus)理论中到达曲线和服务曲线,研究AFDX网络延迟包络,发现流的序列化是获得更紧致上界的重要因素,基于这一事实提出多链路分组技术。最后通过实验表明使用多链路分组技术能够获得更紧致的延迟上界,是一种分析AFDX网络确定性的有效方法。

Using arrival curve and service curve technique of the network calculus theory , we study the AFDX network delay en-velope and find the flows serialization is an important factor in obtaining tight latency bounds .This paper proposes a multi-link packet technology based on this fact .Finally, experiments show that the use of multi-link packet technology can get more tight la-tency upper bound which is an effective method to analyze AFDX network determinacy .
