DevOps, SecDevOps, GitDevOps—stick DevOps on the end of anything, and it will sound cool, generation FOMO in thousands (maybe millions). What does DevOps really mean to network engineers, though? In this episode of The Hedge, we discuss examples of how the Three Ways, (described in Part One of The DevOps Handbook) of Flow, Feedback, and Continual Learning with Joel King, a leading light in this field.

What would the Internet look like—or what kinds of services would need to be developed and deployed—to make boradband class service available to every user? What could this kind of development do to drive entire societies forward? Micah Beck, from the University of Tennessee, joins Tom Ammon and Russ White to discuss universal broadband on this episode of the Hedge.
https://www.theregister.com/2022/08/01/column_7nm_chips_china/ After decades trailing the rest of the world in leading-edge chip making, Chinese sand stamper Semiconductor Manufacturing International Corporation (SMIC) has quietly got into the 7nm business. That's a huge and unexpected leap. Has the West's embargo of the latest fab furniture failed?
https://www.theepochtimes.com/semiconductors-emerge-as-battleground-in-us-china-race-to-make-global-tech-norms-in-their-image_4648523.html Although the United States and China are not engaged in traditional warfare, they are engaged in a war of ideas, trade, and technology, especially in semiconductor hegemony, where both sides are battling for supply and advancement.
https://www.piratewires.com/p/american-hustle-microchip-edition Trade was global, the world was inextricably connected, and your job’s in China now but you should thank us, actually, because everything is cheap and fast and out-of-work factory workers can simply learn to code.
Assume AS65001 is some form of content provider, which means it offers some service such as bare metal compute, cloud services, search engines, social media, etc. Customers from AS65006 are connecting to its servers, located on the 100::/64 network, which generates a large amount of traffic returning to the customers. From the perspective of AS hops, it appears the path from AS65001 to AS65006 is the same length—if this is true, AS65001 does not have any reason to choose one path or another (given there is no measurable performance difference, as in the cases described above from AS65006’s perspective). However, the AS hop count does not accurately describe the geographic distances involved...
At some point, don’t be surprised if IBM ends up acquiring Nutanix. But not now, with Nutanix having a nearly $8 billion market capitalization and possibly commanding a $10 billion acquisition cost.
Some of the most successful and lucrative online scams employ a “low-and-slow” approach — avoiding detection or interference from researchers and law enforcement agencies by stealing small bits of cash from many people over an extended period.
If you were hit by ransomware, you are part of the rapidly growing number of organizations that have had to decide how to respond — legally, quickly and often quietly.
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.
Scott Bradner was given his first email address in the 1970's, and his workstation was the gateway for all Internet connectivity at Harvard for some time. Join Donald Sharp and Russ White as Scott recounts the early days of networking at Harvard, including the installation of the first Cisco router, the origins of comparative performance testing and Interop, and the origins of the SHOULD, MUST, and MAY as they are used in IETF standards today.
Even before it announced that it would seek Chapter 11 bankruptcy, Frontier had a well-deserved reputation for mismanagement and abusive conduct. In an industry that routinely enrages its customers, Frontier was the literal poster-child for underinvestment and neglect, an industry leader in outages and poor quality of service, and the inventor of the industry's most outrageous and absurd billing practices. —EFF
Observability matters. You should care about it. And vendors need to stop trying to confuse people into buying the same old bullshit tools by smooshing them together and slapping on a new label. Exactly how long do they expect to fool people for, anyway? —Charity
As we all know, RPKI is getting a lot of attention and traction nowadays. At the RIPE NCC, we operate one of the five Trust Anchors, a hosted RPKI service, and one of the Validator software packages. A big responsibility that we don’t take lightly. We’re constantly improving code and procedures to ensure we’re following the latest RFC and best practices. Also, security is of key(!) importance. —Nathalie Trenama
Dispatch helps us effectively manage security incidents by deeply integrating with existing tools used throughout an organization (Slack, GSuite, Jira, etc.,) Dispatch leverages the existing familiarity of these tools to provide orchestration instead of introducing another tool. —Kevin Glisson, Marc Vilanova, Forest Monsen
No ideal hash function exists, of course, but each aims to operate as close to the ideal as possible. Given that (most) hash functions return fixed-length values and the range of values is therefore constrained, that constraint can practically be ignored. —Jeff M Lowery
Now we can all appreciate at a fundamental level what it feels like in the datacenter most days, and why Ethernet switch ASIC makers are all trying to push the bandwidth envelope. —Timothy Prickett Morgan
Maintaining a bespoke codebase, training new team members on it, handling operational issues, and adding features is expensive. For many (most?) teams, the cost of rolling your own deployment orchestration system, DSL, or Javascript framework will grow less and less acceptable over time. Save that overhead for the most important things, things that define and differentiate your business. —Forrest Brazeal
The 5G story is everywhere in the American press these days, and not just the American press. You can barely turn around to scratch some needy body part without encountering another article about the wireless telecommunications technology. But the stovepiping in this coverage—the narrowing of the questions asked or answered—is acute. —Adam Garfinkle
First observed in 2009, Slow Drip attacks hit the world stage in a dramatic fashion in early-2014, wreaking havoc on the important middle-level infrastructure of the DNS, particularly on ISPs. Japanese service provider QTNet described the disruption not just of caching resolvers, but of load balancers too. —Renée Burton
Service provider problems are not your problems. You should not be trying to solve your problems the same way service providers do.
This seems intuitively true—after all, just about everything about a train or a large over-the-road truck (or lorry) is different from a passenger car. If the train is the service provider network and the car is the “enterprise” network, it seems to be obvious the two have very little in common.
Or is it?
What this gets right is that if an operator sells access to their network, or a single application, their network is likely to be built differently than the more general-purpose designs used in organizations that must support a wide range of applications and purposes. These differences are likely to show up in the choice of hardware, how the network is operated, and the kinds of services offered (or not).
The idea of object-oriented software originated in the 1960s and rose to dominance in the 1990s. In 2019, most main-stream languages are at least somewhat object-oriented. Despite this obvious success, the paradigm is still somewhat nebulous if you think about it in detail. —Felix
Unlike previous side-channel vulnerabilities disclosed in Intel CPUs, researchers have discovered a new flaw that can be exploited remotely over the network without requiring an attacker to have physical access or any malware installed on a targeted computer. —Swati Khandelwal
The International Society of Automation (ISA) 99 standards development committee brings together industrial cyber security experts from across the globe to develop ISA standards on industrial automation and control systems security that are applicable to all industry sectors and critical infrastructure. —Anastasios Arampatzis
If you run connections to the ‘net at any scale, even if you are an “enterprise” (still a jinxed term, IMHO), you will quickly find it would be very useful to have a time series record of the changes in BGP at your edge. Even if you are an “enterprise,” knowing what changes have taken…
While we tend to focus on work/life balance, perhaps the better question is: how effective are we at using the time we use for work? From a recent study (which you may have already seen): Workers average just 2 hours and 48 minutes of productive device time a day 21% of working hours are spent…
How many tabs do you have open in your web browser right now? Be honest. A dozen? Two dozen? It’s okay, I’m no better. If you’re like me, you blame yourself for your horrible habit of leaving tabs open forever. —Luke Larsen C-level executives often don’t have a clue when it comes to IT and…
KrebsOnSecurity recently had a chance to interview members of the REACT Task Force, a team of law enforcement officers and prosecutors based in Santa Clara, Calif. that has been tracking down individuals engaged in unauthorized “SIM swaps” — a complex form of mobile phone fraud that is often used to steal large amounts of cryptocurrencies…
I just redid my slides for the network troubleshooting seminar I teach on Safari Books from time to time. This new set of slides should make for a better webinar. The outline now covers— Segment 1: Foundations Length: 50 minutes MTTR, MTBM, MTBM Resiliency in terms of troubleshooting Positive feedback loops Automated processes and fragility…
Way back in April of 2014, I started a series over on Packet Pushers called “How the Internet Really Works.” This is a long series, but well worth reading if you want to try and get a handle around how the different companies and organizations that make up the ecosystem of the ‘net actually do…
