The network features modeled in the implementation of CCSDS AOS are to multiplex different kinds of sources into virtual channel data units ( VCDUs) in the data processing module. The emphasis of this work is placed on the algorithm for com-mutating VCDUs into physical channels in the form of continuous data stream. The objectives of modeling CCSDS AOS protocol are to analyze the performance of this protocol when it is used to process various data.展开更多

文摘This paper describes the modeling and simulation of the protocol of CCSDS advanced orbiting systems (AOS). The network features modeled in the implementation of CCSDS AOS are to multiplex different kinds of sources into virtual channel data units ( VCDUs) in the data processing module. The emphasis of this work is placed on the algorithm for com-mutating VCDUs into physical channels in the form of continuous data stream. The objectives of modeling CCSDS AOS protocol are to analyze the performance of this protocol when it is used to process various data.
