While many network engineers think about getting a certification, not many think about going after a degree. Is there value in getting a degree for the network engineer? If so, what is it? What kinds of things do you learn in a degree program for network engineering? Eric Osterweil, a professor at George Mason University, joins Jeremy Filliben and Russ White on this episode of the Hedge to consider degrees for network engineers.
Did you know that today Video, gaming and social media account for almost 80% of the world’s internet traffic? The change in the composition of traffic has been accompanied by a dramatic change in the way content is delivered to the internet user: ISPs and transit providers have diminished in number and importance as the power and profile of a few Content Distribution Networks has increased as content is being pushed closer to the edge. But isn’t that just competition at work? What are the long-term consequences of such a change? In the second episode of our three-part series on “Internet Consolidation”, we talk to Russ White, co-host of The History of Networking and The Hedge podcast and a distinguished infrastructure architect and internet transit and routing expert.
Certifications are a perennial topic (like weeds, perhaps) in the world of network engineering. While we often ask whether you should get a certification or a degree, or whether you should get a certification at all, we don’t often ask—now that you have the certification, how long should you keep it? Do you keep recertifying “forever,” or is there a limit? Join us as Mike Bolitho, Eyvonne Sharp, Tom Ammon, and Russ White discuss when you should give up on that certification.
Open source software is everywhere, it seems—and yet it’s nowhere at the same time. Everyone is talking about it, but how many people and organizations are actually using it? Pete Lumbis at NVIDIA joins Tom Ammon and Russ White to discuss the many uses and meanings of open source software in the networking world.
Can you really trust what a routing protocol tells you about how to reach a given destination? Ivan Pepelnjak joins Nick Russo and Russ White to provide a longer version of the tempting one-word answer: no! Join us as we discuss a wide range of issues including third-party next-hops, BGP communities, and the RPKI.
Steve Bellovin began working on networks as a system administrator, helping to build USENIX, which supports operating system research. His work as a system administrator drew his interest into security and cryptographic protection of data, leading him into working on some of the foundational protocols on the Internet.
A couple of weeks ago Scott Morris, Ethan Banks, and I sat down to talk about a project I’ve been working on for a while—a different way of looking at reaching for and showing your skills as a network engineer.
The security of the global routing table is foundational to the security of the overall Internet as an ecosystem—if routing cannot be trusted, then everything that relies on routing is suspect, as well. Mutually Agreed Norms for Routing Security (MANRS) is a project of the Internet Society designed to draw network operators of all kinds into thinking about, and doing something about, the security of the global routing table by using common-sense filtering and observation. Andrei Robachevsky joins Russ White and Tom Ammon to talk about MANRS.
Consolidation is a well-recognized trend in the Internet ecosystem—but what does this centralization mean in terms of distributed systems, such as the DNS? Jari Arkko joins this episode of the Hedge, along with Alvaro Retana, to discuss the import and impact of centralization on the Internet through his draft, draft-arkko-arch-infrastructure-centralisation.
Started as a consulting company, SUSA was one of the first organizations to begin working in the development and commercialization of LINUX. Through the years, LINUX has become the base for much of the IT world, including many of the open source network operating systems. Dirk Hohndel joins the History of Networking to discuss the origins of SUSA LINUX.
