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.

Register here if you’re interested.

I’m doing a series of three master classes through Juniper on various DC fabric topics—

Join Juniper’s Russ White, a widely published 30-year network engineering veteran, in a three-part masterclass exploring the data center. Choose from classes on data center fabric, physical topologies, or data center security.

You can register here.

From the schedule—

  • Class 1: Data Center Fabric, December 2, 12 PM EST
  • Class 2: Physical Topologies, January 13, 12 PM EST
  • Class 3: Security in the Data Center, February 10, 12 PM EST

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.

On December 13, 2019, I’m giving a three-hour webinar over at Safari Books on How Routers Really Work. From the 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.
