Heavy Networking

Today on Heavy Networking we talk about how to get from a handful of Python scripts to a network automation platform that enables a self-service environment and incorporates the checks and governance required to make sure the automation doesn't blow up the network. Our sponsor today is Itential. Itential offers just such a network automation platform. We talk about how Itential makes it happen, including simple and more complex examples.

Today's Heavy Networking is another roundtable episode. We've assembled a group of network engineers to talk about what's on their minds. Topics today include why other IT departments adn end users are quick to blame the network first, and what can be done about it; using Nokia's open-source Containerlab for testing and development work; and why you shouldn't feel left behind when you hear talk about 400G and 800G networks.

Today’s Heavy Networking, sponsored by Palo Alto Networks, discusses Zero Trust Network Access (ZTNA) across the Secure Access Service Edge (SASE). You could think of ZTNA, as VPN evolved and SASE as SD-WAN evolved. Not only do you get an overlay connectivity fabric, but you also get cloud-hosted security services. We talk about how it all works together, the role of client software, Palo Alto Networks' architecture, integrating an IDP, and more.

Today's Heavy Networking covers Pandas. Not the cuddly bears that eat bamboo, but the Python library that makes it easy for you to work with a set of data. Import Pandas at the top of your Python script, follow one of many Pandas tutorials online, and in short order you’ll be able to perform data operations in a spreadsheet-like way. We talk network automation use cases for Pandas with Rick Donato.

Our topic today on Heavy Networking is SD-WAN monitoring at massive scale. Scale can grow quickly with SD-WAN when you account for the underlay, overlays, gateways, endpoints, and more. We talk with sponsor Broadcom about their monitoring platform and dig into a case study with a Broadcom customer providing global IT infrastructure for thousands of their own customers.

On today's sponsored Heavy Networking we talk with Fortinet about how it converges network and security across the breadth of its portfolio. Fortinet is best known for its firewalls, but the company also offers campus and branch switches, has a wireless portfolio, offers SD-WAN and SASE, provides AI-supported operations, and more. We also talk about Fortinet's approach to the branch office that rethinks networking, security, and performance.

Virtual Application Networks, or VANs, are today’s Heavy Networking topic. Our guest is Ted Ross, motive force behind the Skupper.io project. Skupper builds VANs in Kubernetes clusters that are conceptually like a VLAN or VPN, except that all the magic happens at layer 7. Skupper is based on the Advanced Message Queueing Protocol (AMQP), making it effectively a message bus used to interconnect application messages inside of mTLS tunnels running on top of whatever L3 network is available. If you're confused, don't be. We talk it all out, and explain why it's relevant to today's networking pros.

On today’s Heavy Networking we explore the edge. But where is the edge? In today's conversation with sponsor VMware, it's a remote location where data is being generated. It could be end users in a branch office, or IoT devices and sensors on a factory floor. These edge locations needs integrated compute and networking to run application workloads while also being able to  connect to cloud applications and services. We discuss the VMware Edge Cloud Orchestrator, which provides unified management for networking and compute at remote sites.

In today's sponsored Heavy Networking we explore new features in Cisco Thousand Eyes, an operational tool based on visibility and observability of public and private network. Thousand Eyes has continued to grow into complex operational areas such AWS Network Path, Webex performance, and integrations with Meraki to help you identify and fix network and application performance problems.

EVPN/VXLAN is our topic on today's Heavy Networking. What is it? What’s it for? Should you deploy it? Since you’ve probably already got a network, how do you add EVPN to it? Do you need special hardware? How does EVPN impact your security design? And what are the fundamentals? Our guest with the answers is IT instructor Tony Bourke.
