Didn't know what "Network Field Day" was - from their site:

Networking Field Day is a uniquely focused event, featuring up to 6 presenting companies, and 12 independent thought leaders.

Networking Field Day is an in-person, and live-streaming event that is held twice per year. We bring together the best independent thought leaders and companies within the networking space to discuss advancing technology, and core issues surrounding the networking enterprise IT space.

The event is held as a presentation, but also as an open discussion between our panel of delegates, and the presenters. Allowing the audience outside to hear important questions asked and answered in real time by leading professionals in the industry.
