中文摘要： 在高级在轨系统中，多路复用是研究的重点和难点问题。针对目前多路复用技术的研究多以仿真为主、而少数基于泊松分布源包到达模型的多路复用理论成果又难以准确地反映复杂星上信源复用性能的问题，本课题开展基于自相似业务流的高级在轨系统多路复用模型优化与算法研究，主要包括多路复用优化模型的建立、自适应队列管理算法研究、有限缓存下的帧生成算法研究、边界可移动的具有广泛适用性的虚拟信道调度算法研究，并完成基于HLA/RTI的分布式仿真系统，进行仿真、测试与验证。研究结果可以为复杂星上信源的复用、高级在轨系统接收机的研发、空间通信传输网络体系结构的设计、以及空天地一体化信息网络的研究提供重要的技术支撑。

英文摘要： Multiplexing is a key and difficult research problem of Advanced Orbiting Systems (AOS). Most present research on multiplexing was made by simulation, and a few theoretical results of multiplexing were got by using the on-board source model whose packet arriving rate obeys Poisson distribution. None of them can reflect the real multiplexing performance of complex on-board source models accurately. Therefore, we make research on the optimization and algorithm of AOS multiplexing model based on self-similar traffic, which includes the research on AOS multiplexing model, adaptive queue management algorithm, frame generation algorithm under finite buffer size, virtual channels scheduling algorithm with broad applicability based on movable boundary and the distributed simulation system based on HLA-RTI. The research results can provide technical support for the multiplexing of complex on-board source model, the development of AOS receiver, the design of space communication network architecture, and the research on space earth integrated information networks.
