RESEARCH AND DESIGN OF NOTAM DISTRIBUTION SERVICE MIDDLEWARE
摘要
Abstract
Existing NOTAM processing system uses C /S model,the coupling degree between client and server is very high,and the broadcast-based transmission means makes a lot of redundant NOTAM generated at the client.In view of the features of NOTAM that their generation places are clear and the receiver can be subscribed on demand,and combining with the characteristics of data distribution service (DDS)specification that it enables two communicating parties to reach the loose coupling in space,time and data communications,in this paper we present a DDS specification-based publishing and subscribing model.We design a NOTAM distribution service middleware which supports the QoS policies,define the data structure and work flow of it,as well as the managerial strategy of global data space.According to NOTAMdistribution scene,we use CPN Tools for modelling and simulation.Case simulation results show that the middleware can provide accurate subject-based NOTAMdistribution services,so that proves the feasibility and validity of the design scheme of middleware.关键词
