Heavy Networking from Packet Pushers
Summary: Join the Packet Pushers for weekly (or more!) conversations about data networking. Continuous professional development. Architecture and design, software defined, cloud, routing, switching, security, wireless, campus, enterprise, and more. Technical discussions with vendors about their products, deep dialog with real people who make networks work.
Software defined WAN is a more complicated conversation than optimized routing over multiple circuit types. Modern SD-WAN solutions bring in security, high availability, multi-tenancy, and deep application recognition. They even integrate with other tech in addition to the fancy routing. In today’s sponsored episode, Juniper Networks joins us to talk about its Contrail SD-WAN product. We discuss Contrail SD-WAN and how it differs from other vendors’ approaches, how SD-WAN use cases have evolved. We also dive into three key pillars of Contrail SD-WAN: routing, VPNs, and security. Our guest is Tony Sarathchandra, Director, Product Management – Software Defined Networking Technology and Solutions at Juniper Networks. Show Links: SD-WAN – Juniper Networks
In this episode we talk a second time to network architect Andrey Khomyakov, who’s helped his organization make the transition from traditional to open networking in production. Our first chat with Andrey was in Weekly Show 399. The way it worked out, that ended up being a mostly hardware conversation, which made some of you very grumpy, and you aimed packets at us with the evil bit set. Today, we want to drill into the management and operations side of things and complete our open networking in production conversation. If you’re still grumpy after this episode, maybe it’s time to start your own podcast. We discuss the network stack and the infrastructure environment Andrey works within, look at ongoing operational issues, examine how Andrey and his team use automation, and look at the staffing and training impacts of open networking.

When migrating to an SD-WAN, do you still need a branch router? What does a branch router do? Circuit termination. Routing. QoS. Tunneling. Filtering or even firewalling. Virtual networks. Maybe a few other functions, depending on what you stacked on the box. Can an SD-WAN appliance do all of those things? In the early days, the answer was…probably not all of them, and so you’d often keep your branch router inline with the SD-WAN device. What about today? Do you still need to keep that branch router around, consuming power and running up your maintenance costs? Or can a modern SD-WAN forwarding device be a full replacement for a branch router? Derek Granath, VP of Product Marketing; and Rolf Muralt, VP Product Management for SD-WAN at Silver Peak, join us for today’s sponsored discussion about branch router architecture. We examine the business drivers for eliminating branch routers, discuss potential tradeoffs that come with swapping out the router for an SD-WAN appliance, look at architecture and design implications and caveats, and explore the process of going live without the router.

We&#8217;ve talked about network automation plenty on Packet Pushers. Many of those conversations have been about little things, like writing a script to do a specific task. But is that really network automation? Our guest today is Ken Celenza, and he&#8217;s here to argue that scripting repeatable tasks is just the beginning of the automation journey. Ken, who is Director of Automation at NetworkToCode, works with customers to build and integrate with automation frameworks that address the entirety of their network automation needs. Ken and the Packet Pushers have a wide-ranging conversation about automation, including automation principles, data models and schemas, testing code, and more. While much of today&#8217;s discussion revolves around open source software, this is simply a means to convey a message, and by no means not prescribing any specific solution as the best way forward. If a commercial product fits your needs and your budget, go for it.
