Nyansa is taking performance management and network assurance is relatively unknown sub-genre of network analytics. First generation analytics companies tend to focus on simpler things like visibility into applications, or replay, or reaction purposes. Many analytics products just focus on these limited functions but scale them up to something very large. As you scale up you can’t actually
They apply intelligence to the analysis. The early versions of the product were focussed on understanding performance in Wireless Networks. naturally this extended to Campus (they were catching the Campus trend early)
Today they extending their assurance functions in the WAN. Because they rely on synthetic testing via agents that you install around the network edge, they can be technology independent.
Why ? Lets say that you have a WAN in migration – legacy physical plus SD-WAN. And for some reason your vendor has decided that your first generation SD-WAN product needs to be replaced with a 2nd generation product.
Stop nodding your head over there Cisco IWAN customers.
Use Software Client Agent – running synthetic tests is is good idea. The challenge has always been getting the agent installed onto user nodes i.e. desktops,
Agents are necessary if you want to get deep detail, and accurately represent real traffic. Most analytics companies are using flow export, useful for working at scale but lacks granular data. Its difficult to accurately determine real application performance from a flow, (you aren’t seeing the TCP headers).
