Research and Simulation of Frame Relay Network Based on OPNET
Abstract: The thesis uses OPNET network simulation software to construct virtual frame relay network on the basis of introducing detailedly the frame relay network and the OPNET network simulation software’s main features, modeling mechanism and the simulation step. According to the construction of the network model and the different configurations of three parameters (CIR, Bc, Be) that influences bandwidth dynamic allocation of the frame relay network, it focuses on the analysis of the influence on frame relay network PVC in areas such as traffic, delay and drop-frame ratio. By the analysis of the simulation results, we can see that the frame relay network PVC has higher performance in CIR128 parameters than working in CIR64 conditions.
