机载认知通信网络架构研究

摘要

为了满足作战人员对机载通信网络高移动性、高容量、保障多种业务服务质量（ QoS )、多链互通互操作等需求，考虑到机载网络包含多个异构链路的特点，借鉴商用认知网络思想，提出了一种新的基于认知的网络层收敛分层架构。分析了该架构的特点和优势，给出了该网络架构的认知流程，阐述了涉及到的关键技术。基于认知的网络层收敛分层架构，容易实现多个异构链路资源集成和应用，并在所有协议层认知的基础上，智能地适配动态环境来满足用户端到端指标和提升网络性能。%To meet the airborne communication networkˊs requirements of high mobility, more capacity, multi-trafficˊs quality of service(QoS)ensuring,as well as the interoperability of various heterogeneous links,a novel network-layer converged hierarchical architecture based on cognition is proposed which con-siders the feature that airborne network comprises multiple data links. For this network architecture, the features and strengths are analyzed,and the cognition process is given. The key technologies are clarified. The network-layer converged hierarchical architecture based on cognition,which can easily integrate and u-tilize multiple heterogeneous links, will adapt to the dynamic environment intelligently by exploiting the cognition of all the protocol layers to satisfy the usersˊend-to-end performance and advance the capacity of overall network.
