Visualization Of Network Performance In Network Management

Some important characteristics for 21 centuries are digital, networking and information, the network is the core of the times. Along with people's need to network, of its own accord people's request of network performance also increases continuously increase.It is of great significance to study the performance of computer networks, In order to raise the network speed and overcome the network bottleneck. The network performance analysis and evaluation is also the basis of network plan and optimization, for a network that fully fills the requirement of its user should be a high performance one. Visualization of network performance has a great significance to network performance monitoring, building up a dependable model is easy to control the network's basic things and find the decrease of network performance in time.In this article, the first chapter discourse the background of this article and the purpose of this article. In the second chapter, it is discourse the concept of the network performance, how to measure the data of network performance and the relation between network flow and network performance. In the third chapter, it is discourse how many kind of network flow model and how to build a network performance model based on network flow. In the fourth chapter, it builds a real model relate on campus network. In the last chapter, it discourses development of visualization of network performance and plans to solve the problem in future.
