How sFlow and Sampling Affect Path Reporting

NetFlow Optimizer V2P Network Visibility Module determines path only from information carried in NetFlow. It will use next-hop IP address to build the corresponding path segment when this information is available. When next-hop is not reported in NetFlow, the Module will use statistical methods to build paths, thus the sampling rate of NetFlow or sFlow may have a direct effect on the accuracy of path building. In addition, as path building process is dynamic, sampling may result in showing path segments that are no longer active.
