摘要： 天地一体化网络通常具有覆盖范围广、数据传输量大等特点。现有的一体化网络研究侧重于网络间传输协议，以及如何有效管理网络资源等。但考虑到当前卫星网络数据处理能力相对较差，而地面网络发展已非常成熟，因此将一体化网络与数据中心网络融合，把数据中心网分布式地接入骨干光网络中，卫星作为网络的传输节点与地面分布式数据中心网络构成统一整体；以中国电信骨干网为基础，针对一体化网络的内部传输代价和外部请求代价等多种因素，进行折中，使用整数线性规划得到网络的最优化部署。所提出的网络架构能很好地满足一体化网络的要求，提供了一种具有竞争力的信息平台设计架构。

Abstract: The satellite-ground integrated communication network usually has the characteristics of wide coverage and large amount of data transmission. Current studies concentrate on transmission protocols and resource management. Due to the weak computing power of the satellite network, an integrated satellite-ground communication network with a distributed data center merged with the backbone optical network was proposed which can realize logic link and optical transmission for different component sets in the data center. The satellites were taken as special nodes in the integrated network. And multiple factors were taken into account, such as the cost of internal transfer and external request, to optimize the network architecture by using the integer linear programming (ILP) based on Chinese telecom network. Simulation results show that the proposed network architecture and the optimization technique can solve network design and resource optimization problems well in the integrated network. It also provides a competitive platform for large-scale data transmission and processing.
