Implementation And Testing Of The Netstream Collector System

With the Internet software and hardware technologies in the rapid development of network services and people's growing demand for high bandwidth applications, while network traffic control and management requirements are followed. "NetStream Collector" as a research and analysis of network traffic based on the technical solution, is an advanced network flow analysis and management system that can collect network flow data, the use of network resources to conduct statistical analysis, and provide relevant statements. Enables network managers and timely analysis of network flow information in order to network data management, bandwidth allocation, under the network management, traffic statistics and billing data collection and other business operations to control."NetStream Collector", through the whole network flow information collected, to provide the following functions:(1) Intelligent traffic analysis; (2) abnormal traffic detection; (3) On-line immediately debug; (4) achieving corporate of equipment, bandwidth, network management costs; (5) to avoid abnormal or interrupted due to network services resulting from business losses.The subject of using a distributed deployment, centralized management structure, able to capture a wide range of places to the network traffic information, traffic analysis and can simplify system management and configuration, effectively reduce the total cost of ownership of enterprises (TCO). When the scope of network monitoring, when amplified, NTA solution can be transformed into a distributed architecture, deployed in various places through the NetStream systems to capture the regional network switches and routers, traffic information, and the flow of data gathered through the analysis and processing later transmitted to the central management center, NetStream system, centralized configuration management, data pooled analysis of the whole domain traffic monitoring, exception alerts, as well as flow statement presentation. Therefore, the project has a good promotion and learn.This paper mainly for the following aspects of work:1. To learn more about the needs of the current network, the Research and Analysis Group, status and problems of the network, that "NetStream Collector" program and construction principles, which relates to network management approach by starting the SNMP, to obtain traffic information; packet monitoring approach; and technical team members demonstrated the feasibility of a comprehensive analysis shows that the value of traffic analysis.2. After a detailed understanding of the demand for "NetStream Collector" for development and testing, analyzing its basic functions, involving real-time monitoring, device group, the port group, customized analysis, traffic analysis, application analysis, Source IP analysis, the purpose of IP analysis, conversational analysis and so on.3. Completed the development and testing, the output of the relevant test reports confirm that, "NetStream Collector", to meet the market demand for business;By "NetStream Collector" research and design, testing, allowing operators to meet the network performance management, fault management, access control, traffic management, real-time traffic analysis, decision support, analysis and other statistical and routine reports Operation & Maintenance on demand. So you can prove "NetStream Collector" solve the company's existing network congestion problems and improve return on investment, reduce network construction of the operating costs.
