The Hedge 53: Deprecating Interdomain ASM
Interdomain Any-source Multicast has proven to be an unscalable solution, and is actually blocking the deployment of other solutions. To move interdomain multicast forward, Lenny Giuliano, Tim Chown, and Toerless Eckhert wrote RFC 8815, BCP 229, recommending providers “deprecate the use of Any-Source Multicast (ASM) for interdomain multicast, leaving Source-Specific Multicast (SSM) as the recommended interdomain mode of multicast.”
The Hedge 52: Tobi Metz and the Technologist Question
Tobi Metz asked What is a Technologists? in a recent blog post. Tobi joins Tom and Russ on this episode of the Hedge to expand on his answer, and get our thoughts on the question.
The Hedge 51: Tim Fiola and pyNTM
Have you ever looked at your wide area network and wondered … what would the traffic flows look like if this link or that router failed? Traffic modeling of this kind is widely available in commercial tools, which means it’s been hard to play with these kinds of tools, learn how they work, and understand how they can be effective. There is, however, an open source alternative—pyNTM. While this tool won’t replace a commercial tool, it can give you “enough to go on” for many network operators, and give you the experience and understanding needed to justify springing for a commercial product.
The Hedge 49: Karen O’Donoghue and Network Time Security
Time is critical for many of the systems that make the Internet and other operational networks “go,” but we often just assume the time is there and it’s right. In this episode of the Hedge, Karen O’Donoghue joins Alvaro and Russ to talk about some of the many attacks and failures that can be caused by an incorrect time, and current and ongoing work in securing network time in the IETF.
The Hedge 50: The Challenge of Growing People
Many network engineers complain about their companies not giving them opportunities—but how many think about helping the company grow in a way that allows them to have the opportunities they desire? Scott Morris, aka “evil ccie,” joins Tom and Russ on this episode of the Hedge to talk about the challenges of certifications, growing people, and people learning how to grow in a way what improves the business. Sometimes growing means creating opportunities rather than just waiting for them to knock.
