基于对等网络技术的气象数据共享服务应用

气象数据共享业务广泛采用了单一资料源向各个目标节点分发的方式,针对这种共享业务的特点,设计并实现了一种基于对等网络技术的气象数据共享应用,提供资料源的共享发布以及节点间的共享访问功能。该应用通过搭建的仿真平台模拟实际业务应用,验证了在全国气象宽带网络上实现共享传输的可行性。在随后的小范围业务试验中进一步证明了该应用能够在特定的业务场景中不增加中心节点资源消耗而提升数据共享的传输效率。

Meteorological Data Sharing Service Based on Peer to Peer Network Technology

The distribution pattern of a single source to multi destination nodes is widely used in meteorological data sharing service. According to the operational characteristics of meteorological data sharing service, a meteorological data sharing application based on peer to peer network technology is designed and implemented, which can provide such functionalities as the production and distribution of data seeds and sharing between nodes. By establishing a simulation platform, the application of peer to peer network technology in the national meteorological broadband network (CMANet) is theoretically verified. By small scale experiments, it is proved that the peer to peer application is suitable for dealing with the scene of a single source to multi destination node transmission. It can improve the transmission efficiency of data sharing without increasing the central node resource consumption.
