Upcoming Training: Network Troubleshooting

I’m teaching a three-hour webinar on troubleshooting on the 22nd of April:

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.

This is offered on Safari Books Online through Pearson. I think that if you register for the course, you can watch a recording later.

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.

DC Fabric Intelligence Panel at DCD

On the 10th of February (next week) I’m participating in a panel discussing—

A networking strategy involving disaggregation deployment, overlay network virtualization, automation, and visibility can remedy the complexities with better utilization and performance and ultimately enable network slicing and self-healing abilities. Cloudification of the network is here, but how far do we need to go, and what is the impact on the hardware?

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.
