摘要
随着互联网技术的纵深推进,大物移云的蓬勃发展,传统的网络结构不仅在承载数据流量服务方面存在瓶颈,而且在运维管理和业务部署方面显示不足。在网络提供高稳定和高性能的基础上,构建多数据网络中心,高效进行网络流量调度,实现网络灵活弹性和精细化管理成为下一代网络的重要方向。SDN通过将网络控制平面与数据转发平面进行分离,利用集中控制器实现可编程化的底层网络硬件的操作控制,完成网络资源的统一管理和资源分配。目前空管系统的网络传输和管理依旧是建立在传统的黑盒式的网络转发模式上,若能充分利用新技术,不仅在网络资源利用效率方面,以及传输稳定性和网络管理方面都能发挥更大的优势。
With the development of Internet technology, the traditional network structure not only has deficiency in carrying data traffic services, but also shows insufficient in operation and management. In order to realize high stability and high performance of the network, building a multi-data network center, efficient network traffic scheduling, and achieving flexible and refined network management become an important direction of the next generation network. By separating the network control plane from the data forwarding plane, the SDN implements the operational control of the programmable underlying network hardware by using a centralized controller to complete unified management and resource allocation of network resources. At present, the network transmission and management of the air traffic control system is still based on the traditional black box network forwarding mode. If the new technology can be fully utilized, it will play a role in network resource utilization efficiency, transmission stability and network management.
