NetFlow, jFlow, sFlow and all of their brethren have one thing in common-they can help you understand what makes up the traffic causing your bandwidth utilization. Without the need of probes or sniffers, you can quickly and continuously monitor the makeup of the traffic traversing your most critical links. This will allow you to quickly spot bandwidth hogs and wasteful traffic, and give you an understanding of the applications using your network. Having this understanding is critical in deciding how to best prioritize traffic and furthermore to create policies that eliminate wasteful traffic (torrents, inappropriate streaming media, etc.).
Managing bandwidth needs and consumption is a discipline that has existed since the first 150bps modems connected computer systems together. Today, with multi-gigabit links becoming an everyday reality, we are still facing the same conundrums. Only the number of zeros has changed.
Vess Bakalov, CTO for SevOne Inc., says one thing to remember is that bandwidth and bandwidth management is a means to an end, and not an end in itself. We need adequate performance for our applications and users for the minimum expenditure. To do this effectively, we must first understand what “adequate” means for these users and applications. Only once this often-omitted step is completed can we effectively employ any bandwidth management techniques.
