  • 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 its 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 youve 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 industrys 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.
