Writing An IETF Draft: Document Streams And Document Status

So far in this series we’ve discussed the history of the IETF, some of the tools you might want to use when building an IETF submission, and document formatting. There are other seemingly mystical concepts in the IETF process as well—for instance, what is a “document stream,” and what is a document’s “status?” Let’s look […]

The post Writing An IETF Draft: Document Streams And Document Status appeared first on Packet Pushers.

The net’s long decline into “five giant websites, each filled with screenshots of the other four” isn’t a mystery. Nor was it by any means a forgone conclusion. Instead, we got here through a series of conscious actions by big businesses and lawmakers that put antitrust law into a 40-year coma.

Hedge 178: Defined Trust Transport with Kathleen Nichols

The Internet of Things is still “out there”—operators and individuals are deploying millions of Internet connected devices every year. IoT, however, poses some serious security challenges. Devices can be taken over as botnets for DDoS attacks, attackers can take over appliances, etc. While previous security attempts have all focused on increasing password security and keeping things updated, Kathleen Nichols is working on a new solution—defined trust transport in limited domains.

Join us on for this episode of the Hedge with Kathleen to talk about the problems of trusted transport, the work she’s putting in to finding solutions, and potential use cases beyond IoT.

Upcoming Course: Data Center Fabrics

On the 19th and 22nd (Friday and Monday) I’m teaching the two-part series on Data Center Fabrics and Control Planes over at Safari Books Online. This is six hours total training covering everything from Clos fabrics to eVPN.

Register here.

If you register for the course you can access a recording at a later date. From Safari:

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 Continue reading

On the morning of October 14, 2020, I caught a firsthand glimpse of what it’s like for a traditional media outlet to go up against the vast agglomeration of economic and digital power known as Big Tech—and to do so without the benefit of what economist John Kenneth Galbraith defined as countervailing power.

One of the biggest advantages of IPv6, from a network administration perspective, is the ease of renumbering.
