NetFlow Traffic Analyzer converts that data into charts and tables providing network engineers with a easy way to identify and isolate the cause and source of network problems, as well as provide historical performance information to help plan for future growth. Pie
charts show the distribution of bandwidth across different types of traffic (e.g., HTTP,FTP, VoIP) and across different users. Line charts show the usage patterns over time. NetFlow Traffic Analyzer can also identify the source of external traffic inbound to the corporate network.
