Throughput Performance Analysis of IP over CCSDS AOS
Xiao Chen, Dongli Jin · International Conference on Electric Information and Control Engineering · 2012
It is considered as a reasonable and efficient way to adopt IP over CCSDS AOS protocol model in future ground-space integrative network. In this paper, the IP transfer method over AOS Space Data Link Protocol is presented firstly. After analyzing some aspects that influence the protocol throughput performance, a normalized throughput formula of IP over CCSDS AOS is proposed. Many researches deduce the throughput formula based on the precondition that the data packet length has an integer-multiple relation with AOS frame length. In the formula proposed in this paper, they change independently. Simulations in OPNET Modeler show that the theoretical values calculated by the formula meet the simulation values well. Moreover, the relations of IP packet length, AOS frame length and throughput are also illustrated. The results can provide an important theoretical reference to the performance analysis and configuration optimization in future application of IP over CCSDS AOS protocol model.
