I’m teaching my troubleshooting webinar this Friday. I’ve revamped the slides entirely, so this will likely be a big change for anyone who’s attended previous versions of this. Three hours, 109 slides, and interaction through the chat window … all to develop some really good skills in how to troubleshoot. For those who are curious, I was taught formal troubleshooting skills in my early life in electronics, learning my lessons on ILS, RADAR, and radio systems of various kinds. This webinar is my adaptation of those skills for network engineers.
The Hedge is over 90 episodes now … I’m a little biased, but I believe we’re building the best content in network engineering—a good blend of soft skills, Internet policy, research, open source projects, and relevant technical content. You can always follow the Hedge here on Rule 11, of course, but it’s also available on a number of services, including—
I think it’s also available on Amazon Music, but I don’t subscribe to that service so I can’t see it. You can check the Podcast Directory for other services, as well. If you enjoy the Hedge, please post a positive rating so others can find it more easily.
I’ll be teaching a three-hour live webinar on data center fabrics on the 20th of August—
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.
On the 28th—in two days—I’m doing a master class over at Juniper on DC fabric disaggregation. I’ll spend some time defining the concept (there are two different ideas we use the word disaggregation to describe), and then consider some of the positive and negative aspects of disaggregation. This is a one hour session, and it’s free. Register here.
I’m teaching a webinar on router internals through Pearson (Safari Books Online) on the 23rd of July. From the abstract—
A network device—such as a router, switch, or firewall—is often seen as a single “thing,” an abstract appliance that is purchased, deployed, managed, and removed from service as a single unit. While network devices do connect to other devices, receiving and forwarding packets and participating in a unified control plane, they are not seen as a “system” in themselves.
On April 6 at 9 am PDT I’m moderating the second part of a discussion on the evolution of wide area networks. This time we’re going to focus on more of the future rather than the past, relying on our guests, Jeff Tantsura, Brooks Westbrook, and Nick Buraglio to answer questions about putting new WAN technologies to use, and how to choose between private and public wide area options.
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.
