I’ve rebuilt my data center fabrics live training class, adding a lot of new material across the board, and adding a few new topics. To cover all this new material, the class has been expanded from three to six hours. I’m teaching it for the first time on the 29th and 30th of this month.

From the Safari Books description—

Data centers are the foundation of the cloud, whether private, public, on the edge, or in the center of the network. This training will focus on topologies and control planes, including scale, performance, and centralization. This training is important for network designers and operators who want to understand the elements of data center design that apply across all hardware and software types.

This class consists of two three-hour sessions. The first session will focus on the physical topology, including a short history of spine-and-leaf fabrics, the characteristics of fabrics (versus the broader characteristics of a network), and laying out a spine-and-leaf network to support fabric lifecycle and scaling the network out. The first session will also consider the positive and negative aspects of using single- and multi-forwarding engine (FE) devices to build a fabric, and various aspects of fabric resilience.

The second session will begin with transport considerations and quality of experience. The session will then consider underlay control planes, including BGP and IS-IS, and the positive and negative aspects of each. Routing to the host and the interaction between the control plane and automation will be considered in this session, as well. EVPN as an overlay control plane will be considered next, and finally the relationship between security and control plane design will be examined.

Gentle reminder that I’m teaching a three-hour webinar on Safari Books this coming Friday on Internet operations. The course is roughly divided into three parts.

The first part covers DNS operations, including a high-level overview of how DNS works and some thoughts on how DNS providers “work” financially. The second part is a high-level overview of packet transport, focusing on routing, the different kinds of providers, and how each of of the different kinds of providers “work” financially. The third part is a collection of other odds and ends.

I’m teaching part 2 next month, which I call Navigating the DFZ.

On the 27th of May, I’ll be teaching a three-hour course called 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.

Sorry for the short notice … I’m teaching a three-hour webinar on DC fabrics and control planes this coming Friday, the 25th, through Safari Books Online. This course covers the basics of spine-and-leaf fabrics, as well as some high level information on various DC fabric control plane options (BGP, RIFT, and IS-IS). Please register here.
