摘要
面向"网络无所不达、计算无处不在"的新一代泛在通信和服务一体化网络,多样化的业务应用存在对计算、存储与网络资源等多种维度资源的需求.与此同时,在卫星网络高动态、弱连接场景下,如何高效调度统筹天、地多元异构的算存资源,协同优化组网、传输、存储机制,建立天基计算、存储、网络联合的资源优化模型,提供高质量的天基承载网服务是一个亟须解决的重要问题.针对该问题,在研究天基算存融合技术的发展现状的基础上,研究和分析其对天基承载网架构的影响,并在此基础上提出一种算存融合的天基承载网架构,从组网优化、传输优化、存储优化、服务优化等4个方面系统分析算存融合的天基承载网架构相较于传统天基承载网架构的优势,总结相关关键技术,以期为后续卫星网络的研究、建设和标准化提供有价值的建议和参考.
Abstract
Facing the new generation of ubiquitous communication and integrated service network characterized by"networks every-where and computing omnipresent",diverse business applications have multi-dimensional resource requirements for computation,stor-age,and networking.At the same time,in the high-dynamic,weakly-connected scenarios of satellite networks,how to efficiently sched-ule and coordinate the multi-heterogeneous storage and computing resources of both space and ground,collaboratively optimize the net-working,transmission,and storage mechanisms,establish a space-based computing,storage,and network joint resource optimization model,and provide high-quality space-based carrying network services is an important issue that urgently needs to be resolved.In re-sponse to this issue,based on the research and analysis of the development status of space-based computing and storage integration tech-nology and its impact on the space-based carrying network architecture,a space-based carrying network architecture with computing and storage integration was proposed.From the perspectives of networking optimization,transmission optimization,storage optimiza-tion,and service optimization,the advantages of the computing and storage integrated space-based carrying network architecture com-pared to the traditional space-based carrying network architecture were systematically analyzed.The key technologies were summarized and refined,with the aim of providing valuable suggestions and references for subsequent research,construction,and standardization of satellite networks.
