Nyansa takes a novel approach to analytics with a product called Voyance (for clairvoyance). Their VM-based "software crawler" ingests data from a SPAN port and performs deep packet analysis. The crawler can also read configuration data and other information from a wireless LAN controller (currently Cisco, Aruba, and Rucks are supported). Over time, Nyansa analyzes this data and baselines various operations on your network in order to let you know of possible problems when behavior deviates from your baseline. However, Nyansa goes deeper and focuses on user experience, not just individual network transactions. Nyansa aims to describe the quality of the end user experience in plain English and provide actionable insight about problems when they occur.
However, that's not the most interesting part of the product. The unique part of Voyance is the "Cloudsourced." Voyance takes anonymized metadata about the transactions on your network and ships them off to their cloud. Voyance then analyzes data from all of their customers in order to provide more valuable insight to each customer. Voyance also shows how your network compares to other networks of similar size in your vertical (education, manufacturing, etc). Perhaps your RADIUS server is running slowly compared to similar networks, but you never realized there was room for improvement. Maybe your wireless clients are more affected by congestion during peak hours than clients on similar networks, and you weren't aware this was a problem.
I have not yet had the opportunity to work with Voyance, so I'm not sure exactly how valuable these insights are in the current product. However, the concept of big data analytics for the network intrigues me. Right now, the primary focus of Voyance is wireless networks, but Nyansa is a startup that is rapidly adding features. I think there is great value in big data analytics, and I am very interested to see how Nyansa is able to correlate information and provide insight in ways we have not yet thought of.
Disclosure: I was a guest at Networking Field Day 12, and my airfare and accommodations were covered by Tech Field Day. Some vendors provided promotional swag such as t-shirts, backpacks, and stickers. However, there is no requirement for me to write about any of the presentations at Networking Field Day 12 or provide positive feedback about the technologies presented in any way. Any blog posts I write about Tech Field Day events I write because I am genuinely interested in the technologies.
