People working on net neutrality wish for a "third way" — a clever compromise giving us both network neutrality and no blowback from AT&T;, Verizon, Comcast and others. That dream is delusional because the carriers will oppose network neutrality in any real form; they want paid fast lanes. They have expressed particular opposition to "Title II" of the Communications Act — something telecom lawyers mention the same way normal people might reference the First or Second Amendments. Title II is the one essential law to ban paid fast lanes. more
It's been an interesting couple of months in the ongoing tensions between Internet carriage and content service providers, particularly in the United States. The previous confident assertion was that the network neutrality regulatory measures in that country had capably addressed these tensions. While the demands of the content industry continue to escalate as the Internet rapidly expands into video content streaming models, we are seeing a certain level of reluctance from the carriage providers to continually accommodate these expanding demands... more
A lot of ink and pixels have been spilled about the FCC's new rules for network neutrality. It's impossible to comment sensibly yet about the actual proposal, since as far as I know it's not been published anywhere, but the various news reports have left me confused about just what is being addressed. There are a number of different sorts of behavior that can result in performance differences to the end user... The purpose of this post is to give a simplified (with luck, not too horribly oversimplified) explanation of the different issues here. more
Keynote speaker, and noted security industry commentator, Bruce Schneier (Co3 Systems ) set the tone for the two days with a discussion on how humans name things and the shortcomings of computers in doing the same. Names require context, he observed, and "computers are really bad at this" because "everything defaults to global." Referring to the potential that new gTLDs could conflict with internal names in installed systems, he commented, "It would be great if we could go back 20 years and say 'Don't do that'," but concluded that policymakers have to work with DNS the way it is today. more
Soon after capitulating to Comcast's surcharge demand for improved treatment of its traffic, Netflix got better downstream delivery speeds. Apparently Comcast did not have to undertake a major bandwidth expansion program. Much to the immediate relief of Netflix, Comcast merely needed to allocate more ports for Netflix traffic. So with a reallocation of available bandwidth, Comcast solved Netflix's quality of service dilemma apparently without degrading service to anyone else, upstream or downstream. more
Anyone who still is using the "I'll-just-wait-on-IPv6-because-it-will-never-happen" approach is clearly NOT watching the measurements. First, there was the news last week that Google's IPv6 measurement had crossed over 3% less than five months after crossing the 2% mark. Then today comes word from the World IPv6 Launch measurements program that the February 2014 measurements are up... more
So you are the IT regulator for a country and you are convinced that the shortage of IPv4 address space represents a threat to the development of the Internet in your country and you want to do something about it. Being that as regulator you don't really run the countries IP networks, what can you really do? I've heard many regulators in over 30 countries grapple with this problem. The purpose of this article is to think through some ideas to guide action on using (or not) regulation to drive IPv6 adoption. more
By design, the Internet core is stupid, and the edge is smart. This design decision has enabled the Internet's wildcat growth, since without complexity the core can grow at the speed of demand. On the downside, the decision to put all smartness at the edge means we're at the mercy of scale when it comes to the quality of the Internet's aggregate traffic load. Not all device and software builders have the skills - and the quality assurance budgets - that something the size of the Internet deserves. more
According to the Online Etymology Dictionary, the verb collide is derived from the Latin verb collidere, which means, literally, "to strike together": com- "together" + lædere "to strike, injure by striking." Combined instead with loquium, or "speaking," the com- prefix produces the Latin-derived noun colloquy: "a speaking together." So consider WPNC 14 - the upcoming namecollisions.net workshop - a colloquium on collisions: speaking together to keep name spaces from striking together. more
How do we get more feedback from the operators of networks back into the standards process of the Internet Engineering Task Force (IETF)? How do we help know whether the open standards being developed within the IETF reflect the operational realities of the networks into which those standards will be deployed? If we could get more network operators participating in the IETF standards process, would that result in better standards that are deployed faster? more
One of the hottest topics in the email biz these days (insofar as any topic is hot) is how we will deal with mail on IPv6 networks. On existing IPv4 networks, one of the most effective anti-spam techniques is DNSBLs, blackists (or blocklists) that list IP addresses that send only or mostly spam, or whose owners have stated that they shouldn't be sending mail at all. DNSBLs are among the cheapest of anti-spam techniques since they can be applied to incoming mail connections without having to receive or filter spam. more
At the RIPE 67 meeting in Athens, Greece, the RIPE IPv6 Working Group ran a little experiment to test the feasibility of an IPv6-only network and to identify challenges in user experience. While the results were highly encouraging, they indicated that there is still work to be done before IPv4 can be switched off once and for all. As IPv6 is slowly but surely deployed around the world, we've entered a phase where it's necessary for your devices to be able to communicate using either of the two IP protocols currently in use. more
Given its engineering background, many positive contributions can be made by the engineering community in the broader ICT world to assist in addressing some of the broader internet issues, often addressed within the more limited telecoms environment.. Of course some of this is already happening; however much more work would be needed to strengthen the technical foundations of the internet. Just as an example, the type of issues that could be addressed by a broader ICT engineering foundation could include... more
Much has been said about how Google uses the services they provide, including their mail service, their office productivity tools, file storage and similar services, as a means of gathering an accurate profile of each individual user of their services. The company has made a very successful business out of measuring users, and selling those metrics to advertisers. But can we measure Google as they undertake this activity? How many users avail themselves of their services? Perhaps that's a little ambitious at this stage, so maybe a slightly smaller scale may be better. Let's just look at one Google service. more
The prospect of exhaustion of the IPv4 address space is not a surprise. We've been anticipating this situation since at least 1990. But it's a "lumpy" form of exhaustion. It's not the case that the scarcity pressures for IP addresses are evidently to the same level in every part of the Internet. It's not the case that every single address is being used by an active device. A couple of decades ago we thought that an address utilisation ratio of 10% (where, for example, a block of 256 addresses would be used in a network with some 25 addressed devices) was a great achievement. more
