Design And Implementation Of Visual Traffic Matrix Systm

The information network which is represented by Internet has become one of the most important infrastructures in the modern society; it has penetrated into all spheres of society and become the basis and carriers for knowledge-based economy. And the network had a profound and extensive effect on politics, economy, military affairs, culture and commerce of human society. Therefore, the reliable, efficient and scientific management of Internet becomes increasingly important. How to improve network performance based on the existing network environment, and how to design a network protocol with better efficiency and higher performance for the next generation Internet. And the resolution of these hot issues requires the network to carry out effective evaluation and analysis.This paper presents a visual traffic matrix system based on B/S architecture, aimed at using traffic matrix information combined with location and AS domain information to describe the overall state of the network status and provide a visual display through Google Map under the testing AS domain network environment. The traffic matrix information can be acquired through link load information and routing traffic information between OD pair nodes. This system could be seemed as a method and tool for the internet to provide visual description of network conditions. It can be the foundation of the dynamic monitoring of internet and providing information for Internet scientific management, control and planning, thus the system can provide basis for internet scientific management, effective control and scientific planning.The paper is organized as follow:First, this paper introduces technical background and significance of visual traffic matrix system, and then presents related technologies including the traffic matrix estimation methods and so on. Second, analyzes system requirements and determine achieve objectives, designs principles and functional requirements of the visual traffic matrix system. Followed designs and analyzes the architecture of this system, discusses the specific implementation, and finally realized the basic functions of the system. Finally, the visual traffic matrix system has been tested and the analysis results show that this system could have great significance and research value in practical application.
