An Efficient Sharing Method of Civil Aviation Information Based on Multicast

Abstract

An embodiment of the present invention provides a method for efficiently sharing civil aviation information based on multicast, which belongs to the field of civil aviation information management. The invention is mainly used for efficient sharing of civil aviation related information among various civil aviation participants. The method includes: grouping the information receiving nodes according to the authority of the client, and performing multicast communication on all nodes in the group; in order to improve efficiency, an efficient data processing scheme is proposed, and resources are rationalized according to the depth of the data packet queue according to the first-in-first-out principle Distributed multi-threaded information processing enables information to be processed with higher efficiency. In order to improve the reliability of information sharing, on-demand retransmission and hierarchical multicast methods are provided. The client can apply for data retransmission to the upper node according to its own needs, which can effectively reduce the retransmission pressure of the server and further improve the overall network efficiency. Share efficiency. Based on the improved multicast protocol, the method further improves the sharing efficiency and reliability, provides an efficient information sharing scheme for civil aviation information management and sharing, and improves the overall operating efficiency of the civil aviation information sharing network.

Description

technical field [0001] The invention relates to the field of civil aviation information management, in particular to a method for efficiently sharing civil aviation information based on multicast. Background technique [0002] With the rapid development of the civil aviation industry, the scale of airlines continues to expand, and the number of fleets continues to increase. In 2016, the annual passenger throughput of airports in my country exceeded 1 billion for the first time, completing 1,016.357 million passengers. It can be predicted that in the next few years, my country's air traffic flow will increase more and more, and the coverage of air routes will become wider and wider. However, the strong development of air transport has brought about increasingly prominent contradictions between the increasing demand for air traffic and the relatively shrinking supply of the national airspace system, and problems such as large-scale airspace congestion and large-scale flight d...

Problems solved by technology

[0005] 1) The existing civil aviation communication network uses point-to-point communication to share information. The complexity of the network is high, the cost of development and maintenance is relatively high, and the stability of the network is poor. There is only one communication link between each node. If If the communication link fails, the nodes at both ends of the link cannot share information;

[0006] 2) The information sharing efficiency of the existing civil aviation communication network is not high, and the sharing of information is mostly carried out in the form of request sending. The data producer needs to respond to the data consumer's request one by one. For some time-sensitive information, request When the number of data consumers increases, link congestion may occur, resulting in the inability of information to reach data consumers in a timely manner, seriously affecting the efficiency of information sharing
