Routing Attacks on Internet Services

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

Connectivity as a Vital Consumer Service

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

Just One Bit

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

IETF and Crypto Zealots

I've been prompted to write this brief opinion piece in response to a recent article posted on CircleID by Tony Rutkowski, where he characterises the IETF as a collection of "crypto zealots." He offers the view that the IETF is behaving irresponsibly in attempting to place as much of the Internet's protocols behind session level encryption as it possibly can. ... Has the IETF got it wrong? Is there a core of crypto zealots in the IETF that are pushing an extreme agenda about encryption? more

Usenet, Authentication, and Engineering (or: Early Design Decisions for Usenet)

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

Do We Really Need a New BGP?

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

It's Time to Move From 'Broadband' to 'Infrastructure'

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

Internet Hall of Fame Inductees Gather at GNTC to Discuss New Generation of Internet Infrastructure

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

A Glance Back at the Looking Glass: Will IP Really Take Over the World?

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 75: Imprssions of the Meeting

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
