All kinds of multimedia data are now transferred via network, which need high level QoS standard because of different compression parameters, network parameters and the status of the network. In this paper, we first discribe relevant parameters and results of the correlation between these parameters by using a novel simulation tool. Usually the factors that affect the transmission of the multimedia in the network generally include: GoP (Group of Picture) pattern, compression quantitative parameters (Quantization Value), the Packet length (Packet Size) and Packet Error Rate (Packet Error Rate). Then, based on the basis of Evalvid and NS2 simulation platform, a new set of tools group are set by integrating these two tools. Video traffic trace file is used to evaluate the network structure in existing research and image quality. Moreover, further study of correlation between these factors and image quality is conducted.
