The Modeling and Simulation of Rader Intelligence Data Multicast Transmission in OPNET

IP Multicast is an efficient way of distributing information from a single source to multiple destinations.The transmission of intelligence data source in the radar intelligence data was researched,the intelligence data transmission with multicast based on IP was proposed,then modeling and simulation of the transmission system in OPNET were conducted.Both the single and multicasting transmission ways were compared and analyzed.The result shows that multicast data transmission has good effect on transmission capability and source CPU utilization.
