Intelligent traffic analysis is a network traffic monitoring and analysis technology. It allows the device to perform in-depth analysis on a specified service flow to obtain data about high-precision performance indicators such as the packet loss rate and delay (nanosecond-level) of the service flow. The analysis result can be exported to iMaster NCE-FabricInsight for display or further analysis. It helps O&M personnel monitor the network running status or quickly locate network faults, and provides support for network-wide traffic visualization.
Why Is Intelligent Traffic Analysis Required?
As the digital transformation of industries accelerates, a growing number of important services and applications are being deployed on user networks, resulting in larger networks and more complex application types and data flows. Some problems that may occur during service flow forwarding, such as TCP connection establishment failures and abnormal delay of service flows, bring great challenges to network O&M and pose new requirements. It is important to quickly detect and accurately locate faults, quickly restore services, and effectively improve O&M efficiency. In addition, network traffic visualization has become a trend to implement refined service management in complex network environments.
This technology is implemented using the built-in chip of the device, does not affect the forwarding performance of the device, and reduces the processing load of the remote analyzer.
Intelligent analysis is performed based on different characteristics of service flows, implementing in-depth analysis based on each service flow. In addition to measuring the packet loss rate and delay, it also allows the device to calculate the round-trip time (RTT) in nanoseconds.
The network running status is monitored in real time, and faulty nodes can be quickly and accurately located, improving network stability and reducing network maintenance costs.
The analysis result can be exported to iMaster NCE-FabricInsight, providing strong support for implementing network-wide visualized traffic management.
What Are the Components of the Intelligent Traffic Analysis System?
A typical intelligent traffic analysis system consists of the traffic-analysis data exporter (TDE), traffic-analysis processor (TAP), and traffic-analysis data analyzer (TDA).
The TDE is a device configured with the intelligent traffic analysis function. It determines which service flows are to be detected and sends them to the TAP.
The TAP is a built-in chip on the CPU of a device. It processes and analyzes the service flows received from the TDE, and exports analysis results to the TDA.
The TDA is iMaster NCE-FabricInsight, which is a network traffic analysis tool. It provides a graphical user interface (GUI) for users to easily obtain, view, and analyze collected data.
In actual applications, the TDE and TAP are deployed on the same device. On the network shown in the following figure, the intelligent traffic analysis function is configured on DeviceA.
