基于AOS虚拟信道的服务质量保障机制研究

摘要

Based on the analysis of the characteristics of AOS data link layer protocol and the diversified requirements of future space communication application, a new QoS scheme based on AOS virtual channels is proposed. In this scheme, flow control and shaping algorithm which can satisfy the need of space-earth integrated network communication, as well as the virtual channels＇management and scheduling mechanism are included. Experiments and analysis are conducted to validate the QoS scheme.%在分析AOS数据链路层协议特点的基础上，结合未来空间通信应用中灵活丰富的业务需求，提出了一种基于AOS虚拟信道的服务质量保障方案。该方案中，包括了适用于天地一体化网络通信需求的流量控制及整形算法、基于业务的虚拟信道管理方法和虚拟信道调度机制。最后，通过试验和分析的方法验证了该服务质量保障机制的有效性。
