摘　　要：针对天地异构网络具有网系分散独立、组网技术异构、业务类型多样等特点,传统连通度计算方法很难真实反映天地异构网络的连通状态。文中对网络连通度的内涵进行了丰富,提出一种业务层面的网络连通度计算模型,通过对一种典型天地异构网络拓扑的分析表明,文中提出的连通度计算方法不仅可有效验证不同组网方式中的连通性能优劣程度,也可以评估网络中节点的重要性,为提升网络稳定性提供决策参考。Due to the characteristics of decentralized and independent network systems,heterogeneous networking technologies and various applications in space-earth heterogeneous networks,traditional methods of connectivity calculation are difficult to truly reflect the connectivity state of space-earth heterogeneous networks.This paper enriches the concept of network connectivity,and proposes a data-level network connectivity calculation model.Finally,through the analysis of a typical topology of space-earth heterogeneous networks,it's shown that the proposed connectivity calculation method cannot only effectively verify the connectivity performance of different networking methods,but also evaluate the importance of nodes in the networks,which providing decision-making reference for improving network stability.
