Ten years ago, I wrote an article that looked back on the developments within the Internet over the period from 1998 to 2008. Well, another ten years have gone by, and it's a good opportunity to take a little time once more to muse over what's new, what's old and what's been forgotten in another decade of the Internet's evolution... The evolutionary path of any technology can often take strange and unanticipated turns and twists. more
This post was co-authored by Yixin Sun, Annie Edmundson, Henry Birge-Lee, Jennifer Rexford, and Prateek Mittal. In this post, we discuss a recent thread of research that highlights the insecurity of Internet services due to the underlying insecurity of Internet routing. We hope that this thread facilitates important dialog in the networking, security, and Internet policy communities to drive change and adoption of secure mechanisms for Internet routing. more
Having Comcast et al provide Internet connectivity is like having your barber do surgery because he knows how to use a knife. I was reminded of this when my Comcast connection failed. This is part of the larger topic of consumerization. In the past, we were happy to have products that worked at all. I grew up in the world of consumer products and got my start in software building online services meant for use by non-experts. more
I'm never surprised by the ability of an IETF Working Group to obsess over what to any outside observer would appear to be a completely trivial matter. Even so, I was impressed to see a large-scale discussion emerge over a single bit in a transport protocol being standardized by the IETF. Is this an example of a severe overload of obsessive-compulsive behaviour? Or does this single bit represent a major point of design principle... more
Significant changes to the core Internet protocols are underway due to the increased necessity to overcome limits that have become apparent particularly with regards to performance. more
A Twitter thread on trolls brought up mention of trolls on Usenet. The reason they were so hard to deal with, even then, has some lessons for today; besides, the history is interesting. (Aside: this is, I think, the first longish thing I've ever written about any of the early design decisions for Usenet. I should note that this is entirely my writing, and memory can play many tricks across nearly 40 years.) more
From time to time, I run across (yet another) article about why Border Gateway Protocol (BGP) is so bad, and how it needs to be replaced. This one, for instance, is a recent example. It seems the easiest way to solve this problem is finding new people - ones who don't make mistakes - to work on BGP configuration, building IRR databases, and deciding what should be included in BGP? more
The success of the internet demonstrates that we now depend on network operators to assure that services like telephony work. The carriers are pushing back on neutrality because their business model is threatened by a level playing field. We should be encouraging innovative internet-native business models rather than working to preserve an industry threatened by innovation. more
Confronted with the rapid development of the Internet, the traditional network is facing severe challenges. Therefore, it is imperative to accelerate the construction of global network infrastructure and build a new generation of Internet infrastructure to adapt to the Internet of Everything and the intelligent society. From November 28 to 30, 2017, "GNTC 2017 Global Network Technology Conference" organized by BII Group and CFIEC, will see a grand opening in Beijing. more
In 2003, the world of network engineering was far different than it is today. For instance, EIGRP was still being implemented on the basis of its ability to support multi-protocol routing. SONET, and other optical technologies were just starting to come into their own, and all-optical switching was just beginning to be considered for large-scale deployment. What Hartley says of history holds true when looking back at what seems to be a former age: "The past is a foreign country; they do things differently there." more
RIPE held its 75th meeting in Dubai in mid-October. As usual, there was a diverse set of presentations covering a broad range of activities that are taking place on today's Internet. The topics include issues relating to network operations, regulatory policies, peering and interconnection, communications practices within data centers, IPv6, the DNS, routing and network measurement. If that's not enough, the topic of the Internet of Things has been added as a Working Group in the RIPE pantheon. If you add address policy, database and RIPE services to the mix, you get a pretty packed five days with topics that would appeal to most Internet folks. more
This week, I ran into an interesting article over at Free Code Camp about design tradeoffs... If you think you've found a design with no tradeoffs, well... Guess what? You've not looked hard enough. This is something I say often enough, of course, so what's the point? The point is this: We still don't really think about this in network design. This shows up in many different places; it's worth taking a look at just a few. more
This is the fundamental question that the Internet Society is posing through the report just launched today, our 2017 Global Internet Report: Paths to Our Digital Future. The report is a window into the diverse views and perspectives of a global community that cares deeply about how the Internet will evolve and impact humanity over the next 5-7 years. We couldn't know what we would find when we embarked on the journey to map what stakeholders believe could shape the future of the Internet... more
The blog on the need for a new internet received quite a bit of (international) attention, and with the assistance of colleague John Day, we would like to elaborate a bit further on this. I mentioned RINA as a good example that can be used to have a look at how such a new internet should look like. Interestingly the basics are not all that new. Already in the 1970s, but certainly two decades later, there were plenty of telecoms and computer engineers who started to understand that the future telecommunications work would have more to do with computing than with telecoms. more
The other day several of us were gathered in a conference room on the 17th floor of the LinkedIn building in San Francisco, looking out of the windows as we discussed some various technical matters. All around us, there were new buildings under construction, with that tall towering crane anchored to the building in several places. We wondered how that crane was built, and considered how precise the building process seemed to be to the complete mess building a network seems to be. more
