摘要
针对星地异构网络的拓扑结构高动态、星地链路高差异、网络资源强受限等特征给星地融合业务高效承载带来重大挑战的问题,深入分析星地异构网络发展现状,提出星地异构网络联合QoS保障系统架构.并在此基础上,针对跨域资源统一编排管理、星地联合QoS指标参考体系构建、联合QoS动态策略调控、星地资源按需适配与部署等关键技术进行探讨.
Abstract
The high dynamics of the topology structure,the high variability of the links between space and ground,and the highly lim-ited network resource in the space-ground heterogeneous network pose significant challenges.To address these challenges,a space-ground heterogeneous joint QoS assurance scheme was proposed based on deep analysis of space-ground heterogeneous network development situation.The cross-domain network resource orchestration,construction of a space-ground QoS system,dynamic policy control of heterogeneous joint QoS,and on-demand adaptation and deployment of space-ground network resources technologies were discussed.
