Live Training: How Routers Really Work

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.

DC Fabric Webinar

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.

Infrastructure Privacy Webinar

I’m teaching a three-hour webinar on privacy over at Safari Books on Friday. From the description there—

Privacy is important to every IT professional, including network engineers—but there is very little training oriented towards anyone other than privacy professionals. This training aims to provide a high-level overview of privacy and how privacy impacts network engineers. Information technology professionals are often perceived as “experts” on “all things IT,” and hence are bound to face questions about the importance of privacy, and how individual users can protect their privacy in more public settings.

Please join me for this—it’s a very important topic largely ignored in the infrastructure space.

How the Internet Really Works Part 2

I’m a little late in posting this, but I thought I’d put it out here anyway. Tomorrow I’m teaching through a three-hour webinar, How the Internet Really Works part 2. From the session description—

This training will provide short reviews of many of these systems and a deeper look at the many tools network engineers can use to discover the information they need to navigate through the DNS and routing systems on the global Internet. This training will be arranged as a set of case studies posing a problem, and then working through tools available to gather the information needed to understand the problem.

Upcoming Webinar: How the Internet Really Works (Part 1)

This live training will provide an overview of the systems, providers, and standards bodies important to the operation of the global Internet, including the Domain Name System (DNS), the routing and transport systems, standards bodies, and registrars. For DNS, the process of a query will be considered in some detail, who pays for each server used in the resolution process, and tools engineers can use to interact DNS. For routing and transport, the role of each kind of provider will be considered, along with how they make money to cover their costs, and how engineers can interact with the global routing table (the Default Free Zone, of DFZ). Finally, registrars and standards bodies will be considered, including their organizational structure, how they generate revenue, and how to find their standards.

Live Webinar: How Routers Really Work

This Friday (the 12th) I’m presenting a live webinar on How Routers Really Work over at Pearson. 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.

I’ve changed just a few of the slides from the last time I gave this talk and reordered some things.

Master Class: Resilience in Large-Scale Fabrics

In the aftermath of a major network outage, the natural reaction of most network engineers is to find some way to avoid all future outages—regardless of the cost. The first line of defense against is future outages is redundancy, whether in the form of additional parallel links, new routers, new firewalls, new … whatever, so long as there is more of it so packets have more paths to make it from source to destination.
