Underlay Network Collective

It's been a while, hope all are well. This is a behind the scenes update to share with you what has been going on with us at NC and where we are headed. Short story, we've taken a break but are getting back to it with new content, new ideas, and quite a few changes. If you want a heads up on what is coming, give this episode a listen. If you like surprises, well just ride it out and you'll see soon enough. It's good to be back. 

In this episode, Phil and Brandon interview Kary Rogers, AKA PacketBomb, and discuss the need to drill down into packets when troubleshooting. The group shares a few stories from the trenches on how packets helped them solve issues and Kary explains how he got started looking at Packets for deeper information.

A few weeks ago we released an episode on the fundamentals of gRPC. And while programmatic interfaces are excellent tools for network automation, often that is only the beginning of the story. That’s no exception with gRPC. In this episode we continue down the path of that gRPC conversation and into gNMI, a standards based approached to programmatic interaction with network devices utilizing gRPC. We discuss what it is, how it works, and where it stands in today’s fast moving environment.

In this episode we will discuss the idea of SD-WAN vs. Application Acceleration and WANop.  With the proliferation of SD-WAN we’ve heard a lot of people say that SD-WAN gives you the traffic control, but does it negate the need for application acceleration or WAN optimization tools?  We attack this common misconception and discuss our stance on the matter in this episode.

As the world of network automation continues to evolve, we are seeing different options emerge in how we programmatically interface with our devices. In this episode we take a look at one of the newest and more interesting methods, gRPC. gRPC was developed by Google as a way to execute remote procedure calls in the orchestration of their system and includes such concepts as Protocol Buffers, authentication, bidirectional streaming, and flow control. Join us as we dive into how gRPC works, why it’s different than what you may already know, and why you may want to look into using it to orchestrate your infrastructure.

In this episode, we talk with Dinesh Dutt, former Cisco Fellow & Cumulus Chief Scientist, and Justin Pietsch, former AWS veteran, about SuzieQ. SuzieQ is an open source network observability platform they launched last year. We talk about the general problem space of network monitoring and how the industry needs better tools to understand operational state data.
