History Of Networking – Radia Perlman – Spanning Tree

Radia Perlman joins Network Collective to talk about the history of the Spanning Tree Protocol. Love it or hate it, it’s been a fundamental part of every Ethernet network for the past 30 years and isn’t likely to fade away any time soon.

Episode 13 – A Look In The Mirror

In episode 13, the Network Collective hosts go it alone and take an introspective look at the engineering community, warts and all. We dig into topics relating to ego, hero mentality, overconfidence, short memories, and the negative side of the hype cycle.

History Of Networking – Tony Li – BGP

Tony Li has had a distinguished career working as a networking software architect at some of the largest networking vendors in the world. In this episode of Network Collective, Tony joins us to discuss his involvement in the creation and implementation of BGP, the routing protocol that enables the Internet.

Links, FYI:

The image above is a capture of the original BGP design, sketched on two napkins by Kirk Lougheed of Cisco and Yakov Rekhter of IBM in 1989.

Episode 11 – Shaking The Status Quo

The network engineering community can get a bit stuck on ideas from time to time, and we take a stab at challenging some of these deeply held beliefs in Episode 11 of Network Collective. Join Ethan Banks, Mike Bushong, and the Network Collective crew as we talk about certifications, multi-vendor environments, orchestration, disaggregation, SDN, cloud, and the network industry hype cycle. Yeah, all of that in one 50 minute package. You’re not going to want to miss this one.

History Of Networking – Juliusz Chroboczek – Babel Routing Protocol

Babel is a relatively new routing protocol when compared to some of the more well established options, but due to some of its design considerations, it is very well suited for routing on distributed mesh networks. Babel’s creator, Juliusz Chroboczek, joins the Network Collective team in discussing how Babel came about, some of the design decisions when creating it, and what the future looks like for this emerging technology.

Episode 10 – Grassroots Automation

In episode 10 we look at how to take the first steps towards automating your network. What tools should you use? Should you learn a programming language? And if so, which one? Should you buy or build your automation? Do you need to become a full fledged programmer in addition to being a network engineer? Our excellent panel of guests addresses all of the above and more!

History Of Networking – Daniel Walton – BGP Optimizations

In the late 1990s and early 2000s, BGP had some serious scaling issues that threatened it’s effectiveness as a protocol that could be used for the global routing table.  Significant efforts were made to optimize the resource utilization and convergence time.  Our guest in this episode, Daniel Walton, was part of that effort at Cisco and shares his story about the BGP optimizations that were put in place during that time.  The optimizations include Peer groups, READONLY mode, update groups, update packing, and MRAI.  Sometimes these optimizations, increased capability by 100x previous versions of the code.

Episode 9 – What Your Mamma Never Told You About OSPF

As a continuation of our deep dives into routing protocols, this episode of Network Collective takes a closer look at OSPF. What does graph theory, CAP theorem, and distributed databases have to do with routing? What exactly is that type 4 LSA for? What is OSPF really good for? These and other questions are discussed by our guests Russ White and Nick Russo.
