ARCnet was not an accidental choice in the networks I supported at the time. While thinnet was widely available, it required running coax cable. The only twisted pair Ethernet standard available at the time required new cables to be run through buildings, which could often be an expensive proposition. For instance, one of the places that relied heavily on ARCnet was a legal office in a small town in north-central New Jersey. @ECI’s LighTALK
As long-standing contributor to open standards, and someone trying to become more involved in the open source world (I really need to find an extra ten hours a day!), I am always thinking about these ecosystems, and how the relate to the network engineering world. This article on RedisDB, and in particular this quote, caught my attention—
There’s a longstanding myth in the open-source world that projects are driven by a community of contributors, but in reality, paid developers contribute the bulk of the code in most modern open-source projects, as Puppet founder Luke Kanies explained in our story earlier this year. That money has to come from somewhere.
The point of the article is a lot of companies that support open source projects, like RedisDB, are moving to a more closed source solutions to survive. The cloud providers are called out as a source of a lot of problems in this article, as they consume a lot of open source software, but do not really spend a lot of time or effort in supporting it. Open source, in this situation, becomes a sort of tragedy of the commons, where everyone things someone else is going to do the hard work of making a piece of software viable, so no-one does any of the work. Things are made worse because the open source version of the software is often “good enough” to solve 80% of the problems users need solved, so there is little incentive to purchase anything from the companies that do the bulk of the work in the community.
In some ways this problem relates directly to the concept of disaggregated networking. Of course, as I have said many times before, disaggregation is not directly tied to open source, nor even open standards. Disaggregation is simply seeing the hardware and software as two different things. Open source, in the disaggregated world, provides a set of tools the operator can use as a base for customization in those areas where customization makes sense. Hence open source and commercial solutions compliment one another, rather than one replacing the other.
All that said, how can the open source community continue to thrive if some parts of the market take without giving back? Simply put, it cannot. There are ways, however, of organizing open source projects which encourage participation in the community, even among corporate interests. FR Routing is an example of a project I think is well organized to encourage community participation.
There are two key points to the way FR Routing is organized that I think is helpful in controlling the tragedy of the commons. First, there is not just one company in the world commercializing FR Routing. Rather, there are many different companies using FR Routing, either by shipping it in a commercial product, or by using it internally to build a network (and the network is then sold as a service to the customers of the company). Not every user of FR Routing is using only this one routing stack in their products or networks, either. This first point means there is a lot of participation from different companies that have an interest in seeing the project succeed.
Second, the way FR Routing is structured, no single company can gain control of the entire community. This allows healthy debate on features, code structure, and other issues within the community. There are people involved who supply routing expertise, others who supply deployment expertise, and a large group of coders, as well.
One thing I think the open source world does too often is to tie a single project to a single company, and that company’s support. Linux thrives because there are many different commercial and noncommercial organizations supporting the kernel and different packages that ride on top of the kernel. FR Routing is thriving for the same reason.
Yes, companies need to do better at supporting open source in their realm, not only for their own good, but for the good of the community. Yes, open source plays a vital role in the networking community. I would even argue closed source companies need to learn to work better with open source options in their area of expertise to provide their customers with a wider range of options. This will ultimately only accrue to the good of the companies that take this challenge on, and figure out how to make it work.
On the other side of things, open source is probably not going to solve all the problems in the networking, or any other, industry in the future. And the open source community needs to learn how to build structures around these projects that are both more independent, and more sustainable, over the long run.
Several things of note for the near future.
As of today, I have moved into a role at Juniper networks. You will probably hear more about what I am working on over time, both here and there, and probably other places as well.
I hope to be changing platforms from WordPress to Craft in the spring; work is currently underway. This will likely mean some things about the design of this site will change; others will remain the same. Content wise, I am going to continue highlighting interesting research, soft skills, and networking technologies, but I will be trying to focus a bit more on disaggregation in all of these areas, rather than just floating around all over the place.
More as 2019 develops.
Just when you express hope that the network industry can shed the past, somebody demonstrates it won’t be easy. An interview in Light Reading with Amdocs CTO Anthony Goonetilleke proposes that one of the unsung benefits of 5G is that it will enable operators to charge for services rather than for data. Is this really a 5G revolution in making, or are we simply reprising the same kind of silly stuff that’s been around for decades? —Tom Nolle
The Silicon Valley gospel of “disruption” has descended into caricature, but, at its core, there are some sound tactics buried beneath the self-serving bullshit. A lot of our systems and institutions are corrupt, bloated, and infested with cream-skimming rentiers who add nothing and take so much. —Cory Doctorow
The high-order bit in much of the below is complexity. Hardware, software, platforms, and ecosystems are often way too complex, and a whole lot of our security, privacy, and abuse problems stem from that. —Chris Palmer
How much of the internet is fake? Studies generally suggest that, year after year, less than 60 percent of web traffic is human; some years, according to some researchers, a healthy majority of it is bot. For a period of time in 2013, the Times reported this year, a full half of YouTube traffic was “bots masquerading as people,” a portion so high that employees feared an inflection point after which YouTube’s systems for detecting fraudulent traffic would begin to regard bot traffic as real and human traffic as fake. They called this hypothetical event “the Inversion.” —Max Read
Early numbers indicate that 2018 was a relatively quiet year in terms of huge distributed denial-of-service (DDoS) attacks, but does that indicate quieter times ahead in 2019? While it’s tricky to predict the future in cybersecurity, some experts think that improvements in DNS security are forcing criminals and vandals to change their strategies in order to keep up. —Curtis Franklin, Jr.
The Intel CPU is continuing to shrink, and Ice Lake is promising to bring computing down to a 10nm production node this holiday season. The processor promises to include the typical improvements we see with every generation including better battery performance and faster graphics, but it has a few tricks up its sleeves. —Michael Archambault
No one doubts that artificial intelligence (AI) and machine learning (ML) will transform cybersecurity. We just don’t know how, or when. While the literature generally focuses on the different uses of AI by attackers and defenders and the resultant arms race between the two I want to talk about software vulnerabilities. —Bruce Schneier
It is difficult these days to avoid hearing about blockchain. Blockchain is going to be the foundation of a new business world based on smart contracts. It is going to allow everyone to trace the provenance of their food, the parts in the items they buy, or the ideas that they hear. It will change the way we work, the way the economy runs, and the way we live in general. —Jim Waldo
Yesterday Bloomberg reported that the scandal-beset social media behemoth has inked an unknown number of agreements with Android smartphone makers, mobile carriers and OSes around the world to not only pre-load Facebook’s eponymous app on hardware but render the software undeleteable; a permanent feature of your device, whether you like how the company’s app can track your every move and digital action or not. —Natasha Lomas
I’m teaching a three hour webinar on network complexity on the 8th of February through Safari Books Online. This will likely be the last time I run this course over on the Safari side of things; I’m considering redoing it as a udemy course at some point, or something similar.
