NetFlow is a protocol developed by Cisco Systems for collecting IP traffic information. It enables network administrators to collect and analyze detailed information about the traffic flowing through their network. Here are three reasons why collecting NetFlow data is important for a company network:
To identify applications causing congestion: One of the most important reasons to collect NetFlow data is to identify the applications that are causing network congestion. NetFlow data provides information about the source and destination of traffic, the protocols being used, and the amount of bandwidth being consumed. By analyzing this data, network administrators can identify the applications that are consuming the most bandwidth and causing congestion. This information can then be used to optimize the network and improve performance.
To diagnose slow network performance, bandwidth hogs, and bandwidth utilization: NetFlow data can be used to diagnose slow network performance, identify bandwidth hogs, and monitor bandwidth utilization. By analyzing the data, network administrators can identify which devices or users are consuming the most bandwidth and causing performance issues. This information can be used to optimize the network and allocate bandwidth more efficiently.
To detect suboptimal routing in the network: NetFlow data can be used to detect suboptimal routing in the network. It provides information about the path that traffic takes through the network, as well as the source and destination of the traffic. By analyzing this data, network administrators can identify suboptimal routing and take steps to optimize the network and improve performance.
In conclusion, collecting NetFlow data is important for a company network as it enables network administrators to identify the applications causing congestion, diagnose slow network performance and bandwidth hogs, and detect suboptimal routing in the network. This information can be used to optimize the network and improve performance, which is critical for ensuring that the network meets the needs of the organization.
