Introduction

The system focuses on the daily maintenance work of networks, and realizes network failure analysis and locating with comprehensive and deep analysis of network traffic. NetFlow Manager provides comprehensive network failure analysis from physical layer to application layer, and it can resolve some failures timely and accurately that are difficult to be located with traditional maintenance methods.

For example, if network performance is reduced because of network virus, normal businesses and important applications are unable to run smoothly because illegal businesses or unnecessary applications occupy lots of bandwidth. In addition to finding failures timely and accurately, it can also locate the source of abnormal traffic quickly and resolve the network failure completely.

The system focuses on network planning and design analysis, and provides data evidence for the construction scheme of network expansion, as well as the expansion fee apportionment. With long-term monitoring on network by NetFlow Manager, the distribution pattern and development trend of time, region, and direction of traffic can be revealed accurately, which enables network planners to meet the mid-to-long-term development requirements in scheme design, and determine the fee apportionment strategy of expansion among different branches inside an enterprise.

Wafer NetFlow Manager network traffic analysis system focuses on operation analysis, and it can be widely used in different situations, such as traffic and fee apportionment, user behavior analysis, business component analysis, IDC traffic statistical analysis, interconnection traffic monitoring and auditing, backbone and MAN traffic matrix analysis, illegal VoIP business detection and statistics.

NetFlow Manager Network traffic analysis system is a practical, and efficient traffic and flow direction analysis tool, which provides comprehensive traffic filtering conditions, supports flexible rule configuration, and realizes accurate analysis of traffic. It is widely used in daily network maintenance failure analysis, network design and planning analysis, and operation decision making analysis.

For the maintenance of networks, some network failures from above the IP layer (network layer), such as the low network efficiency resulted from network virus and BT downloading, can be barely handled with traditional maintenance tools and maintenance methods, such as network management system. However, traffic and flow direction analysis is an effective method to resolve these problems. Wafer NetFlow Manager is able to locate the source of such failures quickly, ensuring the high efficiency and availability of network.

For the expansion of network, network planners often lack substantial data to demonstrate the network construction size, and investment fee apportionment. For how long can the current expansion size meet the network operation requirements; whether the connection for an area of MAN to the backbone needs to be expanded; these questions can be answered after the time and region pattern of traffic is revealed. Traffic analysis plays an important role in the expansion fee apportionment among different operators, as well as different provincial branches inside an operator.

Decision making analysis support provides tools for business component analysis and user behavior analysis, as well as reasonable suggestions for network and business planning. The system builds various mathematical models for decision makers in aspects of development planning, network utilization rate, and user satisfaction. With these models, the system can extract objects required to be optimized from the quantized traffic data (including the Internet’s bandwidth and network exit), and show operators the current bottleneck occurring in the network or network objects required to be enhanced. In addition, the system can also show users a complete development scheme according to the data and other parameters of these network objects, and realize the decision making support for network traffic analysis.
