Packet Pushers - Weekly Show

Today's Heavy Networking is a nerdy excursion into EVPN VXLAN, including how it works, why you might want it, and why multivendor interoperability is so difficult with this standard. Guest Tony Bourke and host Ethan Banks also explore hardware challenges, automation strategies, EVPN flooding mechanisms, BGP multi-homing, and more.

Today on Heavy Networking, we talk with sponsor Arrcus about its support for segment routing and the impact it will have on the wider network market, particularly for 5G networks. Our guests from Arrcus are Keyur Patel, CTO and Co-Founder; and Murali Gandluru, Vice President, Product Management.

Lots of network engineers develop tools to help them automate tasks. What happens if you build something so useful it becomes adopted in your organization? Ivan Del Rio, Senior IP Engineer at DQE Communications, stops by the podcast to talk about a tool he built to automate some of his own tasks that is now being widely used. He discusses how and why he built the tool, and how supporting and developing the tool affects his day-to-day responsibilities.

Today's Heavy Networking gets into cloud-delivered security for user access. We're sponsored by Palo Alto Networks, and we'll talk about its Prisma Access service with a customer: Josh Dye, SVP at Jefferies Group. We discuss how Josh pivoted to Prisma Access during the pandemic, how he meets strict security and regulatory requirements for financial services, and more.

Today's Heavy Networking examines the role of deception and "canaries" in network security. A canary sits on a network segment (or multiple segments) and sounds the alarm if it comes under attack. Is this an effective security tool? How is it deployed and operated? What are the drawbacks? We discuss with guest Haroon Meer.

On today's Heavy Networking, sponsored by Palo Alto Networks, we examine what SASE means to you as a network engineer, its effects on how applications are protected and how you provide access to end users, and useful things to think about regarding how SASE services are provisioned and operated while you evaluate whether SASE is right for your org.

Today's Heavy Networking podcast, sponsored by Tempered Networks, dives into how Tempered builds a software-defined perimeter with native zero trust, leveraging the Host Identity Protocol (HIP), Tempered's Airwall software, cryptographic identities, and secure overlays. Our guests from Tempered are Jeff Hussey, Founder and CEO; and Bryan Skene, CTO.

Today's Heavy Networking thinks hard about how to manage security policy in modern IT infrastructure. We get into sources of truth, application modeling and application dictionaries, approval workflows, and more--all in the context of automation. Our guests are Ken Celenza and Brett Lykins from Network To Code.

Today's Heavy Networking explores how First Bank uses Aruba’s SD-WAN to advance its cloud migration, support remote workers, and provide secure segmentation for IoT devices. We also discuss the growing trend of SASE and First Bank’s strategy around cloud-delivered security services. Our guests are Marc Ashworth, CISO at First Bank; and Damon Ennis, VP of Engineering at Aruba Networks.

Today on Heavy Networking, we talk about how to roll your own network automation workflow. Guest Steve Puluka has developed an automation workflow system that uses GitLab and Jenkins, among other tools, to make sure the network devices he supports are pure gold. We talk about how it works, and how you can put your own together.

On today's sponsored Heavy Networking podcast we examine the use of SmartNICs and DPUs to offload networking and security processes. We also discuss the use of the SONiC network OS to run on SmartNICs and DPUs, with P4 as a programming layer. Dell Technologies is our sponsor, and our guest from Dell is Ihab Tarazi, Sr. VP and Networking CTO.

5G, IoT, and low-latency virtualized edge services present a major opportunity for providers and enterprises to build and consume new services in the metro network. On today's Heavy Networking episode, sponsor Juniper Networks is here to share its vision of new metro architectures. Our guests are Amit Bhardwaj, Sr. Director Product Management; and Mats Nordlund, Sr. Director Product Management.

Today's Heavy Networking explores how to communicate complex, nuanced technical topics to non-technical people. We examine how to balance finicky details with broader outcomes, discuss the value of editing and review, share writing tips, and more.

In today's sponsored Heavy Networking podcast, Juniper Networks is here to make the case that service providers are building cloud services at the edge that enterprises can take advantage of. Joining us is Kevin Hutchins, SVP, Strategy & Product Management at Juniper, to assert that service providers can thrive and compete in a cloud-based economy, and that Juniper will be a key part of that ecosystem.

On today's Heavy Networking we dive into Intel's portfolio---including Tofino, SmartNICs, P4, and more---to understand how it unlocks the compute power of your data center. Our guest is Mike Zeile, Data Center Group Vice President and General Manager of End-to-End Network Applications at Intel. Intel is our sponsor.

Does EIGRP need defending? Can this protocol even be defended? Ethan Banks and Zig Zsiga debate the case for EIGRP and discuss major use cases, design considerations, scaling tips, and more.

Today's Heavy Networking episode is a grab bag of topics delivered in our community roundtable format. Five engineers join Ethan Banks and Greg Ferro to talk about subjects including IPv6, SmartNICs, firewall rule management, becoming a manager, and other topics.

On today’s Heavy Networking, we explore how to get network data you reference all the time and store it in a CSV using Ansible, the Genie parser, and Jinja2. Our guide for how to assemble these gears and get them cranking is John Capobianco, automation maven and Sr. IT Planner and Integrator for the House of Commons in the Canadian Parliament.

In today’s sponsored show with Juniper Networks, we dive into Juniper's Paragon product portfolio, which measures service quality for critical applications. The portfolio allows service providers and enterprises to get deeper visibility into, and automated control over, their networks. Our guests from Juniper to walk us through the portfolio are Peter Weinberger and Jonas Krogell.

In today's podcast, sponsored by IP Fabric, we dive into the IP Fabric Network Assurance platform. This platform gathers network configuration and state, and then builds a network model using a graph database. The result is a "digital twin" of the network that engineers and security teams can use for troubleshooting, to plan and verify changes, for network and security analysis, and to enable closed-loop automation. Our guests from IP Fabric are Pavel Bykov, CEO; and Daren Fulwell, Network Automation Evangelist.
