Network Field Day 16

Gian Paolo Boarina returned from his first Networking Field Day event having seen presentations from eight different companies. The topics ranged from network visibility, to analytics, intent-based networking, SDN, and more. We’re looking forward to hearing Gian’s impressions of each!

NFD16 delegate

We were very excited to be able to have Gian Paolo Boarina join us at Networking Field Day last week. We’re looking forward to seeing his reactions to the presenting companies after his first event. It’s always interesting to get the perspective of someone drinking straight from the firehose for the first time.

NFD16 day one – Veriflow

Gian Paolo got a look at Veriflow’s formal verification of networks at Networking Field Day last week. This works by collecting control plane information, not actual data or flows, to build a normalized model of how the network should be operating. This can be used with their policy tools to create an intent-based networking solution. Gian was impressed (calling it “a great product), but would like to see integration with Netflow/IPFIX data to validate the models on their roadmap.

Veriflow – The Formal Future

Daniel Kuchenski got a crash course in formal verification from Veriflow’s recent Networking Field Day presentation. Using a collector VM, Veriflow sends the operational state of networking devices to their verification engine. This formally verifies that the network is operating as intended. Veriflow recently released CloudPredict, which allows you to extend this modeling to AWS. All told, it was one of Daniel’s favorite presentations from the event.

Startup Veriflow Adds New Intent-Based Capabilities To Its Network Verification Software

At Networking Field Day, Veriflow demonstrated bringing intent-based network verification to the enterprise. Drew Conry-Murray looks at these features, which include using formal verification to build software models to see if your on-site and cloud networks are performing as you intended. Drew likes the fact that its designed for networks as they exist, not positing hypothetical networks an engineer has no way of building within an organization. Ultimately, using these software models puts the onus on organizations to use them effectively for managing networks.

NFD16 First Impressions

Networking Field Day just wrapped up earlier this month, but Ivan Pepelnjak already has his initial impressions in order. He nominated Avi Freedman from Kentik as winner of the “Nerd Factor” category for the event, with a close runner up from Apstra. The formal verification for networks from Veriflow also merited an initial mention. We’re looking forward to reading more from Ivan on each.

Apstra at NFD16

In this post, Jeremy Schulman gives a preview of what to expect from Apstra’s return presentation at Networking Field Day. They’ll have their CTO, Sasha Ratkovic and Derick Winkworth (aka @CloudToad) discussing the core concepts of intent-based networking. We saw AOS version 1.0 at last year’s Networking Field Day presentation, so it’ll be exciting to get an update!

Looking Forward to Networking Field Day 16

Networking Field Day is coming up next week, and we’re happy to have Pete Welcher returning as a delegate. He’s getting to revisit a company he saw at a previous event, Apstra and their intent-driven networking solution. Overall, Pete is looking forward to the presentations and talking to his fellow delegates.
