摘　　要：新一代天基信息系统采用“骨干+接入”的网络架构,可以为用户提供数据、话音、视频等多种类型业务。针对新一代天基信息系统多业务传输保障需求,提出了IntServ与DiffServ相结合、多域协同的按需服务质量保障技术方案。对于保障类业务进行接入控制和资源预留,为其提供绝对的传输保障;对于非保障类业务进行业务优先级排队和调度;并对跨层QoS机制、跨域QoS协同进行设计。最后搭建原型系统,进行了测试验证,测试结果表明该方案可以很好地支持多业务传输保障。The new generation space-based information system adopts a“backbone+access”network architecture,which can provide users with data,voice,video and other types of services.This paper proposes a technical solution for on-demand service quality assurancecombining IntServ and DiffServ and multi-domain collaboration in a converged network environment.Access control and resource reservation for guarantee services to provide absolute transmission guarantee,priority queuing and scheduling for non-guaranteed services,and design for cross-layer QoS and cross-domain QoS collaboration.Finally,a prototype system was built,tested and verified.Test results show that the solution can well support multi-service transmission guarantee.
