No Fines for Comcast

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

Advertising Pays for a Lot of Things… What Happens When the Ad Budget Dries Up in a Recession?

Doing some research on the effects of the Great Depression in the 1930s, I started wondering what happened to advertising during that period. Although I haven't turned up any detailed studies, I took a look at the various archives of advertising that allow Internet access to their exhibits, and noted the general move to less expensive, more localized advertising, and fewer adverts for more expensive goods. It made me wonder what will happen to online advertising if the current credit crunch starts to drive a worldwide recession... more

Consequences of Opt-in Better Than Best Efforts Internet Routing

While attending the International Telecommunications Society's 17th bi-annual conference I attended yet another network neutrality session. Economists predominated at this conference and their collective read on network neutrality emphasizes the need for ISPs to "extract value" from content providers primarily by converting zero cost peering with ISPs into specific payments from individual content sources. I have no problem with offers of non-neutral, "better than best efforts" routing options to content providers who voluntarily opt in, particularly if the offer is made transparently and anyone can opt in. What troubles me is the impact of opt-in on content providers that opt out... more

Vint Cerf Comments on Government’s Role in Internet Broadband Access

Some offhand comments by Google's Vint Cerf at a recent event seem to have a triggered a panicky "Vint Cerf proposes nationalizing the Internet" buzz that's been ramping up fairly rapidly. Holy BitTorrent, Batman! Army paratroopers seen dropping into parking lots at AT&T and Comcast, while the Transportation Security Agency orders us all to remove our shoes before surfing the Web! Settle down, everyone. As usual with these kinds of stories, the truth is significantly different from the breathless buzzing. Here's how Vint described his thinking on this issue to me... more

IPv6 and MEID’s… Stop Choking on 32 Bits

Both the Internet and North American cellphones are choking under a 32 bit limitation and reactions from protagonists involved in both cases offer striking similarities. 1983 saw the debut of IPv4 and North American mobile telephony started in earnest with Bell's analog AMPS (Advanced Mobile Phone Service). Responding to the need to uniquely identify the growing number of mobile devices in order to bill their owner, the FCC ordered that handsets be equipped with a unique identification number embedded on a chip. This became the 32 bit ESN... more

Identifying Spam: MAAWG’s Latest Documents Improve Accuracy of Reputation Systems

The Messaging Anti-Abuse Working Group (MAAWG), of which Return Path (my employer) is a very active participant, met recently in Heidelberg, Germany. Among other exciting projects, they finished two new best practices documents which have been lauded in the press as a big step towards stopping botnet spam... more

The FCC Stumbles Into Internet Filtering

What could be bad about free wireless Internet access? How about censorship by federally mandated filters that make it no longer "Internet." That's the effect of the FCC's proposed service rules for Advanced Wireless Service spectrum in the 2155-2180 MHz band, as set out in a July 20 Notice of Proposed Rulemaking. Acting on a request of M2Z Networks, which wants to provide "free, family-friendly wireless broadband," the FCC proposes to require licensees of this spectrum band to offer free two-way wireless broadband Internet service to the public, with least 25% of their network capacity. So far so good, but on the next page, the agency guts the meaning of "broadband Internet" with a content filtering requirement. more

Cisco: P2P Flat in North America? Some Experiencing Major Growth

North American p2p went from 370 petabytes in 2006 to only 416 petabytes in 2007 according to Cisco's figures. Since U.S. users increased 16% in the same period, that's a drop in p2p per user and a significant drop in p2p as a percentage of all traffic. There's a major margin of error in these figures, so I'm calling it "flat." That's very different from pre 2007 experience, when p2p grew rapidly. It severely contradicts what many in Washington D.C. are saying... more

Bit Caps, Consolidation, and Clearwire

The news that Comcast, Time Warner, and AT&T are all considering capping use of their networks -- so that "overuse" would trigger a charge -- has prompted intense discussion of just why these network operators are moving in this direction. One camp suggests that these operators have to do *something* to manage congestion, and because any protocol-specific discrimination plan raises howls of protest from the Net Neutrality side of the fence adopting bit-usage discrimination schemes is inevitable. It's the least-bad approach, following this view. more

SPIT is in Everyone’s Mouth, Though Not Yet in Everyone’s Ears

Spam over Internet Telephony (SPIT) is viewed by many as a daunting threat. SPIT is much more fatal than email spam, for the annoyance and disturbance factor is much higher. Various academic groups and the industry have made some efforts to find ways to mitigate SPIT. Most ideas in that field are leaning on classical IT security concepts such as intrusion detection systems, black-/white-/greylists, Turing tests/computational puzzles, reputation systems, gatekeeper solutions, etc... We identified the lack of a benchmark testbed for SPIT as a serious gap in the current research on the matter, and this motivated us at the to start working on a first tool for that. more
