Abstract
As the first layer of AOS multiplexing, the frame scheduling performance has a great effect on the efficiency of multiplexing. Traditional researches about the scheduling model mainly focus on the source packet arrival model of Poisson process. In this paper, an ON/OFF source arrival model and Pareto distribution of AOS multiplexing in self-similar service traffic is used to establish a isochronous frame-generated method through rigorous theoretical analysis, which results in a calculable formula of average packet delay and MPDU average multiplex efficiency. According to simulation of MATLAB, the simulation curve coincides with that of theory. The novel model contributes to the improvement of average packet delay and MPDU average multiplex efficiency on AOS.

As the first level of Advanced Orbit Systems (AOS) multiplexing, the frame generation technique has a great effect on utilization efficiency of the multiplexing channel
With ON/OFF source arrival model and Pareto distribution, a relational expression of average efficiency of MPDU multiplexing and a calculable formula of average packet delay are derived, which would contributes to the improvement of performance of AOS
Summary
Consultative Committee for Space Data System (CCSDS) is an international standard organization, which composed of multinational space organization. The frame generation in AOS, known as packet channel multiplexing, is a mechanism of sharing virtual channels for all types of data generated from the upper layer [5] It is to multiplex and encapsulate all kinds of data with same or similar demands in the service and to transmit packets in the same virtual channel into MultiiJOE ‒ Vol 14, No 7, 2018. The isochronous frame generation [6] is to encapsulate the data packets from higher levels into a frame at a fixed interval time and send them. It mainly focuses on the estimation [7], simulation [8], and analysis of MPDU multiplexing efficiency of AOS [9]. The simulation curve coincides with that of theory
