Applications of OPNET Simulation Technology in the Network Project and Design

Network simulation is a technology that simulates network actions through mathematics modeling and statistical analyzing,consequently achieves the specific network performance parameters,objectively provides the reliable basis for the network planning design,reduces the network construction cycle,makes the policy more scientific in the network construction,and reduces the investment risk of network construction.A network simulator-OPNET is introduced,which has powerful function in the field of network project and design.The OPNET technology is analyzed from three aspects,the key characteristics,the three-layer model mechanism and the simulation ways and procedures.Finally,a practical case is presented illustrating OPNET simulation in the network project and design
