I’m teaching another master class over at Juniper on February the 10th at 12 noon PT (3PM ET):

It’s typical to think about scale, speed, oversubscription, and costs when designing a data center fabric. But what about security in a world increasingly focused on privacy, data protection, and preventing downtime caused by cyber breaches? This session will consider how data center fabric software and control plane components can impact security, including the ability to effectively manage segmentation policy, controlling failure domains, and the impact host-based routing has on fabric security.

On the 22nd, I’m giving a three hour course called How the Internet Really Works. I tried making this into a four hour course, but found I still have too much material, so I’ve split the webinar into two parts; the second part will be given in February. This part is about how systems work, who pays for what, and other higher level stuff. The second part will be all about navigating the DFZ. From the Safari Books site:

This training is designed for beginning engineers who do not understand the operation of the Internet, experienced engineers who want to “fill in the gaps,” project managers, coders, and anyone else who interacts with the Internet and wants to better understand the various parts of this complex, global ecosystem.

I’m teaching another master class over at Juniper on the 13th at 9AM PT:

Spine-and-leaf fabric is the “new standard,” but how much do you know about this topology, its origins, and its properties? This session will consider the history of the Clos, explain the butterfly and Benes, look at why a fabric is a fabric and why “normal networks” are not, and cover some key design considerations when building a fabric.

Just a gentle reminder that on Monday (just a few days from now) I’m teaching a three hour webinar over at Safari Books on How Routers Really Work. From the course description—

This training will peer into the internal components of a router, starting with an explanation of how a router switches packets. This walk through of a switching path, in turn, will be used as a foundation for explaining the components of a router, including the various tables used to build forwarding tables and the software components used to build these tables.

The first hour of material in my new BGP course over at Ignition dropped this week. I’m not going to talk about configuration and other operational things—this is all about understanding how BGP works, why it works that way, and thinking about design. This course will apply to cloud, Internet edge, DC fabric, and other uses of BGP. From the official site:

BGP is one of the fundamental protocols for routing traffic across the Internet. This course, taught by networking expert and network architect Russ White, is designed to take you from BGP basics to understanding BGP at scale. The 6-hour course will be divided into several modules. Each module will contain multiple video courses of approximately 15 minutes each that drill into key concepts. The first module contains four videos that describe how BGP works. They cover basics including reachability, building loop-free paths, BGP convergence, intra-AS models, and route reflectors.

I’m teaching a webinar on troubleshooting theory on the 20th; register here. From the course description:

This training focuses on the half-split system of troubleshooting, which is widely used in the electronic and civil engineering domains. The importance of tracing the path of the signal, using models to put the system in context, and the use of a simple troubleshooting “loop” to focus on asking how, what, and why are added to the half-split method to create a complete theory of troubleshooting. Other concepts covered in this course are the difference between permanent and temporary fixes and a review of measuring reliability. The final third of the course contains several practical examples of working through problems to help in applying the theory covered in the first two sections to the real world.
