Bob McCouch of Herding Packets comments: Last fall, I attended the Tech Field Day NFD8 event, and one of the presenting companies was Nuage Networks. This was actually the second time I’d seen Nuage present at an NFD event, the first one being NFD6 a year earlier. Upon my return from NFD8, I did a short write-up of […]

Big Switch Chaos Monkey Network Testing
Lindsay Hill comments on his blog: Whenever you build a complex system, you need to test that it works as expected, including properly handling failures. It’s easy enough to do simple component failure testing, but harder to do rapid automated failure tests. Big Switch is showing that it can be done though. Hopefully we can keep improving our […]
Using Schprokits to Automate Big Switch’s Big Cloud Fabric
Jason Edelman’s comments on his blog: To clarify, I had access to Schprokits and access to Big Switch kit. Schprokits does not natively support Big Switch integrations (maybe in the future now??). I worked with the Schprokits team to understand “how to extend” Schprokits and how to create custom actions. I then […]
Secrets Behind A10 Health Monitors
John Herbert of Lame Journal comments: Whether you use A10, f5 or some other load balancer, you’re probably used to the idea of health monitors, or “health checks”. The load balancer periodically performs some kind of connectivity test to the servers that are used to service a given VIP (virtual IP), then if a certain […]
Cisco ACI Fabric Forwarding In A Nutshell
Ethan Banks of The Peering Introvert comments: One of the most interesting elements of SDN architectures is traffic forwarding. How does traffic get from one point to another in an SDN world? Cisco ACI’s traffic forwarding approach is intriguing in that it neither relies on the controller for forwarding instructions, nor does it rely on […]
IPv6 Adoption in the UK
David Gee of ipengineer.net comments: One of my biggest annoyances for a while has been the lack of interest in IPv6 in the UK. There just isn’t a thirst for it. I’m pretty convinced it’s down to lack of sales support by out coin operated fraternity of technology touting army of salesmen (and women). Justifications […]
Knowing Your Audience…and Showing It
Lindsay Hill writes on his blog: We all know that you’re supposed to “Know Your Audience.” Doing so improves engagement, and avoids faux pas like “Suggested Tweets.” But recently I realised that this doesn’t have to be subtle. Drop hints early on in your presentation that you’ve taken the time to understand the audience — […]
All Eyes on voice…
Amy Arnold of Just Another Day At The Office writes: ThousandEyes announced something they called “new and shiny” at Networking Field Day 8 and it definitely caught my attention — not just because the word shiny was used* — but also because voice was the target of the announcement. I am quite used to being […]
Big Switch Labs for SDN Learning: A Sneak Peek!
Nick Buraglio of The Forwarding Plane writes: At the time of this writing, the lab consists of 3 modules: Building cloud fabric, monitoring fabric and dynamic provisioning of monitoring fabric. Since there is quite a lot going on with this cloud based SDN classroom, for the scope of this post I’ll concentrate on the first, […]
No more duplicate frames with Gigamon Visibility Fabric
Chris Marget of Fragmentation Needed comments: Gigamon presented their Visibility Fabric Architecture at Network Field Day 8. You can watch the presentation at Tech Field Day. One of the interesting facets of Gigamon’s solution was it’s ability to do real-time de-duplication of captured traffic as it traverses the Visibility Fabric (a hierarchy of monitoring […]
