Recently, several networking vendors are marketing “network analytics” in their offerings, such as Extreme’s Purview and Juniper’s Cloud Analytics Engine. The term “analytics” is a tad over-used these days, and means many things to many people.
Simply put, networking analytics provides insight into what devices are on the network and how they are communicating with each other. This helps networking teams who are increasingly responsible for more and more applications/services traversing the network via an increasing number of locations. So, the killer use-case is network troubleshooting (is it the app or the network?), but this analytics information could also be monetized by the network operator (think public venue… if they want to know what sites people are going to…).
Traditional network switching/routing vendors are including this as an add-on capability to help them differentiate their products, in a similar manner to what Arista does with Network Packet Brokering capability. While analytics from your networking vendor is a relatively new concept, the use of networking analytics tools is not. We publish a Magic Quadrant for Network Performance Monitoring and Diagnostics (NPMD), which covers this space in depth. This includes vendors such as Riverbed, Fluke, Network Instruments, Netscout, CA and others. So if you’re considering investing in “network analytics” , I would recommend you check out this research

Summary: Network professionals must support an increasing number of technologies and services. With adoption of software-defined networking and network function virtualization, troubleshooting becomes more complex. NPMD tools help detect application issues, identify root causes and perform capacity planning.
