What is gNMI?
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.

The case for App Acceleration with SD-WAN
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.

Introduction To gRPC
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.

High Value Certifications For 2021 And Beyond
In looking back on 2020 we think about all of the things we did to keep ourselves busy. Some of us starting baking bread at home, some started home gardens, and if you are part of the networking twitter community you probably saw a lot of folks chasing some new certifications. Throughout 2020, with isolation and the pandemic in full swing, networking vendors and certification facilitators found ways to serve the community by providing remote exams and free trainings. Whether it was the need to stay busy or trying to learn something new, whatever your reason is to pursue a new certification, the question is which one? With 2020 now behind us and our future constantly changing, which certifications will give you the biggest impact for 2021 and beyond? In today’s episode we talk to 2 prominent networking influencers: Ernest the “Cisco Panther” and Yasmin Lara the “mom who can fix anything” We’ll go over topics covering their certification journey how it’s positioned them to continue growth throughout the pandemic and which certifications give you the best bang for your buck for 2021 and beyond.

The Real Intent Behind Intent Based Networking
Networking is one of the industries where every time a good idea comes around it doesn’t take long for that idea to get coopted and turned into something to sell products, often drastically changing the intent of the original idea. Today we’re going to try to roll back the clock a bit and discuss the original idea around Intent Based Networking. What is it? What does it mean for you? And how do products fit into the original intent.
