基于网络演算的确定性以太网性能评估
Performance evaluation on deterministic ethernet based on network calculus
摘要
Abstract
The theoretical tool of network calculus theory was adopted to conduct the performance re‐search on complex topologies of deterministic Ethernet .Based on the simple star topology ,cascade to‐pology and dual‐channel cascade topology was proposed .Firstly ,the deconvolution theory was used to establish the network calculus model of the two complex topologies .Secondly ,the simulation model of the two complex topologies was established .Lastly ,the simulation results were compared with the theory results to analyze the determinacy and real‐time of deterministic Ethernet .Besides ,depending on the different size of time‐triggered data ,rate‐limited data and best‐effort data were analyzed per‐formance in end to end delay ,throughput and packet loss rate .Analysis results show that the simula‐tion results fit well with the theory values ,the complex topologies also have a good performance ,and the fault‐tolerance function plays well in dual‐channel cascade topology .关键词
