Gartner has defined itself a new market segment in “Network Performance Monitoring and Diagnostics” (NPMD) that highlights
“solutions from AppNeta, CA Technologies, Corvil, Fluke Networks, Genie Networks, HP, Infovista, JSDU (via Network Instruments acquisition), Lancope, NetScout Systems, Niksun, Orsyp, Paessler, Riverbed, and SevOne.”
These are all good companies but these companies mostly rely on hardware devices as probes to capture data. For example, Corvil was once a QoS appliance before it became a carrier DPI engine and now provides PerfMon for financial markets as a core business. The hardware appliance is core to its business.
I take the view that SDN-enabled network devices will provide same or very similar data. And with platforms like OpenDaylight, Cisco ACI and VMware NSX will have the same functions built into their ecosystems.
I would say that NPMD is ripe for disruption by SDN and most of the these companies will struggle to turnaround to OpenFlow/OpFlex monitoring as a replacement to their expensive and profitable hardware unit.
For example, Extrahop Networks who have a good NPMD platform but has already adapted to having capabilities for deployments in Amazon EC2. They are already turning away from the hardware only focus.
Wondering if anyone else agrees with the point of view that SDN technologies are disruptive to the existing network monitoring companies, especially those that use hardware to capture data from the network ? If not, what am I missing ?
