The first is bandwidth utilization monitoring which can provide quantitative data. Network traffic analysis is primarily done to get in-depth insight into what type of traffic/network packets or data is flowing through a network. The deep packet inspection contemplates the review and evaluation of the headers and the data portion of the packets. It is one thing to know that a given network segment suffers from congestion but being able to figure what is causing that congestion gives you a whole new perspective. The differences between one form and the other are concentrated in the methodology used. WireShark is a very popular packet analyzer. We’ll start by having a look at Cisco’s NetFlow technology and its multiple variants before we have a look at S-Flow, a competing system that is somewhat different in how it operates although it serves a similar purpose. This type of monitoring will let you see how much traffic is going by at a specific point on a network but it won’t provide any data on the nature of this traffic. It will, for instance, let you view traffic by application, by conversation, by protocol, and several more viewing options. Only a few NetFlow analyzers and collectors can handle sFlow data as the two are too different. In other words, the starting point is an abstraction -called “traffic flow”- that corresponds to all the traffic that shares certain common characteristics and moves from one network host to another.For example, if we consider all the traffic that a station and a server can share, that traffic that is part of the same conversation or has the same objective will be considered as flow.
