The Fat Pipe - All Packet Pushers Pods

Today's Heavy Networking is a crash course in executing a new wireless deployment for engineers who are wired, not wireless, experts. We explore how and why to gather user and technical requirements, understanding the RF environment, channel management, and more. Our guest is Robert Boardman.

You know your frame from your packet. You can explain how bridging tables are populated. Ethernet is your friend from as far back as 100 meg half duplex regularly plagued your life.

Wireless? Not so much. You know some stuff, but maybe a big wireless project just landed in your lap and you’re feeling a little overwhelmed. What you need is a crash course. A primer.

On today’s episode, we explore how to do a new wireless deployment when you’re a wired, not a wireless, expert.

Our guest is Robert Boardman, a solution and sales engineer for Mist Systems. This is not a sponsored podcast, we’re just tapping Robert’s expertise.

We roam through a variety of topics including:

* Gathering user and technical requirements, including the physical location and clients

* Understanding the RF environment

* Channel management

* How to choose the right APs and whether all your APs should come from the same vendor

* Controller and cloud architectures

* Post-installation validation and operation

On Heavy Networking, Chris Parker joins Ethan Banks to delve into the details of a perplexing troubleshooting session with a recalcitrant firewall, how the problem was finally solved, and what Chris learned from the experience.

We do a bit of troubleshooting on today’s Heavy Networking podcast.

Turning up a new circuit should be easy. Some IP addressing, maybe a routing adjacency to bring up, or perhaps a default route.

Do some pings, run a speed test, check for interface errors, make a few notes in the NMS, and that’s about it. Routine stuff for any network engineer.

Except sometimes it isn’t. What happens when all the normal stuff seems okay, but you’ve got weird connectivity problems? How do you fix that issue?

Our guest is Chris Parker, a network engineer who works for a London ISP, and is also a Juniper Networks ambassador. Chris blogs at Network Fun Times.

He and Ethan start the show talking about certifications, why Chris has earned so many, and his favorite books and blogs that helped him.

Then they walk through an issue that Chris encountered with an SRX firewall, the troubleshooting steps he took and why they didn’t help, and then how a “monitor traffic” command finally provided the clue he needed.

Chris also shares his personal recommendations on troubleshooting:

* More eyes

* Say it out loud

* Trust no one. Trust nothing. Make no assumptions

* Improve your process

* Don’t assume all vendor kit works the same

* Even “RFC-compliant” doesn’t mean it all works the same

* Automation is good because humans suck where robots excel

State and regional IPv6 task forces advocate for IPv6 adoption by state governments and the private sector, and educate engineers. In today's episode we chat with George Usi, the Co-Chair of the California IPv6 Task Force to learn more about the task force's goals and what it's achieved to date.

When you’re building applications in the cloud, there are knowns, known unknowns, and the unknown unknowns.

You can read documentation, scour blogs, talk to colleagues, and draw on your own experience, but sometimes you just to have to sail off the map and into territory marked “Here there be dragons.”

Or maybe puppies. Hopefully it’s puppies.

Today’s episode looks at how one developer dealt with surprises and unexpected issues that arose as his company built an Orchard-based Content Management System (CMS) application on Azure. The goal was to replace an existing CMS running on premises.

My guest is Jamie Phillips, a Senior Software Development Engineer at SentryOne. During the day he works on Windows, but at night he’s all about Linux.

We discuss issues that the project ran into, including quirks of Azure’s App Service; why the application ran into performance problems and how they fixed it; storage challenges; and how Azure AD, while useful, caused maintenance problems because of password resets.

You can find Jamie on Twitter @phillipsj73, on GitHub as phillipsj, and read his blog at phillipsj.net.

Today's Day Two Cloud podcast looks at how one developer dealt with surprises and unexpected issues that arose as his company built CMS application on Azure, including storage problems, user identity quirks, and more.

Today’s Tech Bytes episode explores the Link State Vector Routing (LSVR) protocol, an IETF draft standard that lets you use BGP to build a data center fabric.

Our sponsor is Arrcus, and we discuss how LSVR works, including how it reduces resource consumption in routers and speeds convergence, and how it can be used with BGP EVPN.

Our guests explain how LSVR ties to Arrcus’s ArcOS network operating system, what it can do for organizations building CLOS fabrics in their data centers, and common use cases.

Joining us from Arrcus are Keyur Patel, CTO and cofounder; and Murali Gandluru, VP of product management and marketing.
