Richard Bennett designed the twisted-pair cable system and related protocols for Ethernet, elements of the Wi-Fi protocol, and the Distributed Reservation Protocol for Wi-Media UWB. He’s a long-time architect and inventor of network systems supporting the Internet infrastructure and a former fellow at ITIF and AEI in Washington DC. He founded High Tech Forum.

Unlike most new IETF standards, DNS over HTTPS has been a magnet for controversy since the DoH working group was chartered on 2017. The proposed standard was intended to improve the performance of address resolutions while also improving their privacy and integrity, but it's unclear that it accomplishes these goals. On the performance front, testing indicates DoH is faster than one of the alternatives, DNS over TLS (DoT). more
As we enter the seventh round of the net neutrality fight, advocates continue to make the same argument they've offered since 2002: infrastructure companies will do massive harm to little guys unless restrained by strict regulation. This idea once made intuitive sense, but it has been bypassed by reality. ... When Tim Wu wrote his first net neutrality paper, the largest telecoms were Verizon, AT&T, and SBC; they stood at numbers 11, 15, and 27 respectively in the Fortune 500 list. more
After five years of bickering, the FCC passed an Open Internet Report & Order on a partisan 3-2 vote this week. The order is meant to guarantee that the Internet of the future will be just as free and open as the Internet of the past. Its success depends on how fast the Commission can transform itself from an old school telecom regulator wired to resist change into an innovation stimulator embracing opportunity. One thing we can be sure about is that the order hasn't tamped down the hyperbole that's fueled the fight to control the Internet's constituent parts for all these years. more
The FCC has run three days of workshops on the National Broadband Plan now, for the purpose of bringing a diverse set of perspectives on broadband technology and deployment issues to the attention of FCC staff. You can see the workshop agendas here. The collection of speakers is indeed very diverse. As you would expect, the session on eGov featured a number of government people and a larger collection of folks from the non-profit sector, all but one of whom has a distinctly left-of-center orientation. Grass-roots devolution arguments have a leftish and populist flavor, so who better to make the argument than people from left-of-center think tanks? more
According to National Journal, Susan Crawford is joining the Obama administration in a significant new role... This does not make me happy. Crawford is not a technologist, and the job that's been created for her needs to be filled by a person with deep knowledge of technology, the technology business, and the dynamics in research and business that promote innovation... more
It depends on whose numbers you like. Andrew Odlyzko claims it's up 50-60% over last year, a slower rate of growth than we've seen in recent years. Odlyzko's method is flawed, however, as he only looks at public data, and there is good reason to believed that more and more traffic is moving off the public Internet and its public exchange points to private peering centers. Nemertes collects at least some data on private exchanges and claims a growth rate somewhere between 50-100%. more
Like several other engineers, I'm disturbed by the white spaces debate because it focuses on what I regard as the wrong question. The White Space Coalition argues that showing that a system can be constructed that prevents interference between White Space Devices and television broadcast signals compels the Commission to offer up the White Spaces for unlicensed use. This is far from obvious. more
A fellow named Paul Korzeniowski has written a very good, concise piece on the Comcast action at the FCC for Forbes, Feds And Internet Service Providers Don't Mix. He manages to describe the controversy in clear and unemotional language, which contrasts sharply with the neutralists who constantly use emotionally-charged terms such as "blocking," "Deep Packet Inspection," "forgery," and "monopoly" to describe their discomfort. more
After voting on the Comcast order today, Kevin Martin and his Democratic Party colleagues issued press releases telling us how they saved the Internet from Comcast's discriminatory practices, but they've failed to release the actual order they adopted and subsequently re-wrote. Commissioner McDowell wasn't allowed to see the revised order until 7:00 PM the night before the meeting. Rumor has it that high-level spin doctors are still trying to remove all the rough edges, inconsistencies, and factual errors. more
Note: this is an update on my earlier story, which incorrectly said that the AP reported that Chairman Martin was seeking to impose "fines" on Comcast. In fact, the story used the word "punish" rather than "fine," and a headline writer at the New York Times added "penalty" to it "F.C.C. Chairman Favors Penalty on Comcast" (I won't quote the story because I'm a blogger and the AP is the AP, so click through.) Much of the initial reaction to the story was obviously colored by the headline. more
Here's my opening remarks from Media Access Project's Innovation '08 in Santa Clara this morning. A DVD will be available shortly. This was a lively discussion, with Google and Vuze on the case. Good morning and welcome. My name is Richard Bennett and I'm a network engineer. I've built networking products for 30 years and contributed to a dozen networking standards, including Ethernet and Wi-Fi... I'm opposed to net neutrality regulations because they foreclose some engineering options that we're going to need for the Internet to become the one true general-purpose network that links all of us to each other, connects all our devices to all our information, and makes the world a better place. Let me explain. more
