We conduct network traffic analysis for a couple of key reasons. First, we look for traffic anomalies, such as unexpected increases or decreases in network traffic within specific segments. This helps us determine if the network needs to be re-architected. We also analyze peak bandwidth and bandwidth consumption across various network segments, which is crucial if someone is planning to transition to software-defined networks. The network traffic analyzer tool allows us to simulate scenarios and compare before-and-after results. Additionally, it supports traffic sources like NetFlow and SFlow, and we regularly check the quality of service using NetFlow. The tool handles a variety of protocols, such as NetFlow version 5 and version 9, JFlow, and SFlow, making it independent of the underlying technology.
