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.

Debunk the Junk- 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.

80/20 Rule For SaaS and IaaS

In this episode we discuss the 80/20 rule for SaaS and IaaS, what it is according to Vince, and why you should care. Is this a temporary phenomenon due to the pandemic and WFH or is it how we should view WAN traffic from now on?  We’ll answer that question and more in this episode.

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.

Show Notes

  • Compare/contrast the original intent of Intent Based Networking with what it has been marketed as
  • Trajectory towards Intent Based Networks
    • Traditional models
    • Automation added
    • Orchestration added
    • Intent added
  • Three pillars of Intent Based Networking
    • Defining Intent
    • Fulfilling Intent
    • Assuring Intent
  • Gaps between the vision and current reality
  • Approach vs. Product – what’s the right way to think about Intent Based Networking

Introduction To The Riverbed Technical Podcast

In this episode we (Brandon, Phil, and Vince) introduce ourselves and share what drives our passion for network visibility and performance.  While we are all from Riverbed, this is not your typical vendor podcast.  We have a lot planned to discuss around why visibility is a key that networks must focus on today.  We talk about cloud and what that overused blanket term really means to us, and how migrations to the cloud are a key time to ensure that we have visibility into apps that have been forgotten, where our data is, what’s leaving the cloud, and what the performance looks like, before, during, and after. We touch on Security, AI/ML, and performance as well, as we setup shop and plan to discuss these areas in further detail.

Lessons Learned From A Regional Provider Network

Running and building a regional provider network is a challenging proposition. When your network is your profit center, every decision is made through a different lens. Add a global pandemic on top and you’re certainly going to walk away with a few lessons learned. In this episode we talk with Marek Isalski about his experiences building and operating a regional provider network in the UK.

Running IPv6 Only Networks

In today’s episode we’re talking about IPv6. More specifically, we discuss what it takes to run an IPv6 only network. Why now? And why not dual stack? Well, in the middle of November (2019), the US government put out a memo outlining their updated guidelines and expectations for IPv6. In it, they mandate a future vision of 80% of devices connected to IPv6 only networks by 2025. That’s not that far away. So, as many of our peers who work in US federal organizations are preparing for a world that is IPv6 only, we figured it might be time for us to do the same.

NTC – Damien Garros – Source Of Truth

In this episode, we talk with Damien Garros from Network to Code. Damien works with clients on a daily basis architecting and implementing Source of Truth strategies for network automation solutions.  We spend time talking through how to best approach source of truth, how to solve the age-old problem of populating the source of truth, and talk about several open source projects that can help you on your source of truth journey.

Navigating Change

All you have to do is take a look around you and it becomes obvious that people just simply don’t like change. Conversely, all you have to do is look around you and it becomes obvious that our industry is in almost a constant state of change. How do we reconcile these things? How can we adapt to the ever changing world around us, and how can we utilize this knowledge to be more effective influencers of change within our organizations and within our jobs.

Show Notes

Now this topic, like many of the topics that have become episodes on Network Collective lately, was prompted by a conversation in the Network Collective Slack. It has an IPv6 bend to it, as IPv6 seems to be the change the industry continually likes to avoid, but the avoidance of change isn’t something new. Nick, I’m going to start with you. Do you think the aversion to change in our industry is just a reflection of being human, or do you think there is more to it than that.

Coping With The Learning Treadmill

Networking can feel like it’s a never ending game of catch up when it comes to learning. During our live stream with Tim McConnaughy we chat about this learning treadmill and how to navigate the never ending need to learn in this industry.

Building A Network (no, the other kind)

A conversation in the Network Collective Slack prompted some conversation about how to build a network. No, not the packet switched networks that we’re all so familiar with, but rather a personal network of peers. Not everyone has the privilege to attend trade shows and conferences throughout the year, and all of us have lacked that privilege for a while now due to Covid, so how does one build a pervasive network without in-person events. We also discuss some methods to set yourself apart from the crowd in ways that don’t include peer relationships.

War Stories – The Trilogy

From working in unbelievable environments to dealing with unexpected bugs, the longer that you do networking for a career the more likely it is that you have a story or two from the trenches to share. Listening to other’s adventures can serve both as a cathartic release and as a warning for roads to leave untraveled. In today’s episode we talk with some experienced engineers about their stories. If nothing else, you as the listener can have some laughs at our expense. Enjoy!
