    eBPF, Cloud-Native Networking, And Other Modern Networking Trends

    We welcome back to Heavy Networking two guests deep in the guts of what’s going on with all the modern trends in networking: cloud-native, containers, eBPF, Kubernetes, DPUs, and so on. If you live in that world, there’s a possibility that one or both of them contributed code to the projects that push your packets around.

    In this show, Brent Salisbury and Dave Tucker are going to give their insider’s view of what’s been going on in cutting-edge networking tech. You’ll walk away with a better idea of what to pay attention to as new-to-you companies, acronyms, and open source projects hit the networking landscape in the months and years to come.

    Deploying An Active-Active Data Center Network For Private Cloud (Sponsored)

    Deploying An Active-Active Data Center Network For Private Cloud (Sponsored)

    Welcome to Heavy Networking. Our topic today is building a data center fabric. Pluribus Networks is our sponsor.

    Pluribus brought along a customer to talk about their active/active DC deployment. We’ll get into stretching layer 2 safely, Pluribus’s L3 capabilities, operational concerns of active/active when the DCs are many hundreds of miles apart, and the pressure of delivering customer-facing services that drove the selection of the Pluribus architecture.

    Our guests are Mike Capuano, Head of Technical Marketing; and Alex Godfrey, Professional Services Engineer, both from Pluribus Networks. They are joined by Josh Collazo, Infrastructure Engineering Manager for Interop Technologies, a Pluribus customer.

    Cloud-Native Kubernetes Networking For CSPs (Sponsored)

    Cloud-Native Kubernetes Networking For CSPs (Sponsored)

    Today on Heavy Networking, sponsor Juniper Networks talks about software defined networking for cloud service providers. Wait, I just said “software defined networking.” Is that a blast from the past? Is that even a thing anymore?

    Well, yes. SDN is a thing. In fact, the original SDN model of a centralized control plane programming a distributed forwarding or data plane is pretty much everywhere these days. In fact, SDN is a major solution component to the challenge of deploying secure networks to support apps in multi-tenant environments.

    And if that sounds like a bunch of buzzwords, we’re going to get into details as we go forward. We’ll start with the big ideas around service provider and cloud provider network services in 2022, both how they collide and are complementary, and then get an update on Juniper’s Contrail product. A quick preview of the Contrail discussion is that it’s Kubernetes-native via CNI now.

    Our guest is Shean Leigon, a product manager at Juniper.

    Data Center Networking And Observability In 2022 (Sponsored)

    Data Center Networking And Observability In 2022 (Sponsored)

    As we approach the end of 2021, it’s informative to look back at how much change has gone on in the industry. One of the biggest transitions we’ve seen in enterprise networking has taken place in the data center. Software-defined approaches that emerged over the past decade have matured and are being deployed in production.

    Today we talk with Juniper Networks in a sponsored episode about its Apstra Intent-Based Networking (IBN) platform and how Apstra is transforming the enterprise data center. Our guest is Mike Bushong, VP, Cloud-Ready Data Center at Juniper.

    We discuss:



    * Why data center operations is more important than hardware speeds and feeds

    * What Intent-Based Networking means

    * Juniper’s business case for acquiring Apstra

    * The benefits of multi-vendor hardware and software support

    * How observability differs from typical monitoring

    * Juniper’s view of where the market is going

    * More

    Heavy Networking 610: Network Automation With Nautobot

    Let’s talk sources of truth for network automation today. You okay with that? Excellent, glad to have you on board for this conversation with Jason Edelman and John Anderson of NetworkToCode.

    We’re going to discuss a Nautobot, an open-source software tool that can serve as a network source of truth for automation. If you’ve used NetBox, Nautobot will have a rather familiar feel.

    We discuss:



    * How Nautobot differs from NetBox

    * Using Nautobot with Python and Ansible

    * Nautobot use cases including source of truth, an app platform, and for automation

    * Major features

    * Architecture recommendations

    * Nautobot limitations

    * What’s on the roadmap

    Innovation Or Stagnation - A Year-End Networking Review

    Innovation Or Stagnation - A Year-End Networking Review

    Today’s Heavy Networking considers the current state of networking technologies and the networking market. We discuss the notion of multi-location networking, whether “software-defined” has finally arrived, how network engineers and the industry are dealing with complexity, and whether organizations can “cloud” their way out of legacy problems.

    We also debate whether we’ve seen any significant innovations over the past year, if the industry has stagnated, or if we’re simply trying to stay on top of disruptions caused by cloud, the Covid pandemic, and the erosion of traditional network boundaries.

    There are no guests or sponsors on today’s show, just Greg Ferro, Ethan Banks, and Drew Conry-Murray having a bit of a year-end chin-wag.
