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.

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.

Value Added Resellers play a critical role as trusted adviser in the networking industry.  However, many customers don’t make the most of their VAR relationships.  In Episode 12, our hosts explore the VAR relationship with VAR engineers Zach Miller and Warren Jackson.  We explore the ups and downs VAR life for both resellers and customers.

Daniel Walton joins Network Collective for a second time to discuss the problem of churn in BGP routing tables, the steps taken to solve this problem, and the addition of add-path to the BGP protocol.

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.

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.

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!

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.

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.

In this, the very first History Of Networking episode of Network Collective, Fred Baker joins us to talk about his involvement with Quality of Service and the Differentiated Services model. Fred Baker has been involved with the IETF since 1989, served as IETF chair between 1996 and 2001, and has done much work to establish standards in the data networking industry.

For many the world of wireless networking is a world that is dark and full of terrors, but it doesn’t have to be that way. In this episode of Network Collective, the panel reveals many of the most common wireless networking misconceptions so you too can be a wizard in the black art of RF. I promise, no RF math was used in the filming of this episode.
