NetFlow – What It Is All About
NetFlow is a network protocol created by Cisco for the collection & screening of network traffic
flow through switches and routers. NetFlow is widely used by IT pros to scrutinize network
traffic flow & volume to make sure from where traffic is coming, where it’s going to, and also
how much traffic is being produced. NetFlow-enabled routers forward traffic statistics as
NetFlow documents which are then gathered by a NetFlow collector. The collector performs the
real traffic analysis & presents it to the users. Collector can be a software or hardware appliance.
NetFlow has turned out to be a de-facto industry standard and is backed up by platforms other
than CISCO comprising, Juniper, HP, Dell and Netgear, Huawei, Ericsson and Alcatel-Lucent.
While screening the performance of networks
and applications, the more insight you’ve into
the real traffic, the better. If you collect all the
traffic the data volume will be very high.
NetFlow offers this insight and also reduces
the volume significantly. Without the
requirement of sniffers or probes, you can
swiftly and constantly keep an eye on the
composition of the traffic navigating your
most complicated links. MIMIC NetFlow
simulator creates an easy way to generate
NetFlow traffic from thousands of devices in the shape and pattern you want. It enables you to
promptly pick up bandwidth hogs, DDos attacks & inefficient traffic, and offers you a familiarity
of how applications are making use of your network. No doubt, these insights are significant in
deciding how to prioritize traffic and on the formation of policies to eradicate inefficient traffic.
MIMIC NetFlow Simulator generates a variety of flows and enables you to fully test your
applications. Since you have a complete control over generated flowsets you can easily verify
that your graphing application is correctly displaying the values, and your collector correctly
collects precisely generated flowsets. The MIMIC NetFlow Simulator is the industry’s first
integrated simulation tool supporting NetFlow and SNMP. It allows developers to perform real
world, integrated device simulations. Network management now will be much easier than ever
before.
