Compunication Performance Evaluation Method Based On Hierarchical Routing Modeling

With the quick development of network applications in the every walk of life and the limited speed of improvement of network basic technology and facilities, the problem about less and deficient Internet channel capacity is more and more severe, and users'complains about the network QoS become more and more loud. In order to change this situation, while we are trying to update the basic network facilities and expedite the pace to build broad-band networks, we should put more emphasis on the work of performance analysis, which is necessary for the optimization of network design and upgrade.To achieve that goal, we investigate the basic means to analyzing the network performance, survey the leading works of scientific research institutes abroad and inland on communication performance evaluation, and summarize the parameters affecting the network performance and their implications and properties in compunication performance evaluation. Basing on the relations of these performance parameters, we put up the architecture and ways to test and optimize the network performance.Mathematics analysis and computer simulation are two main methods that can be applied to network performance analysis. Among the current network applications and network services, QoS (Quality of Service) is our main concern. According to the requirements and the nature property of current network topology, we theoretically propose an hierarchical QoS route model. In the model, with the QoS parameters in the user call and the link status in the topology architecture, a route can be chosen to meet the QoS requirements. It is obvious that the network...
