中央核心处理式多层级流量管理系统网络结构设计

Central Processing,Multi⁃level Network Framework for Air Traffic Flow Management System

大型流量管理系统为民航空管系统各级流量管理单位、航空公司和机场等相关单位提供了持续的监视、分析和协商工具。针对流量管理运行过程中相关单位地理位置分散,其连接网络存在的网络异构、带宽有限和远距传输等问题,结合网络安全性要求,提出了一种中央核心处理式多层级流量系统网络架构,以满足协同流量管理运行网络化对网络传输效能和可靠性等需求。

A large-scale air traffic flow management system provides the consistent surveillance,anal⁃ysis and consultation functions during the air traffic flow managements for the user,including multiple air traffic flow management units,airlines,airports,and other participants.These problems are physi⁃cally distributed,and the networks between them always have the characteristics of heterogeneity,limited bandwidth and long distance transmission.A central processing,multi-level network frame⁃work is proposed to adapt to safety,efficiency and reliability requirements during collaborative air traf⁃fic flow managements.
