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
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
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
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
Google co-founder Larry Page came to Washington last week to take on the National Association of Broadcasters (NAB), the lobbying group that represents over-the-air television stations. It's a whole new adversary for the beleaguered broadcasters, who have been fighting cable and satellite television for years. The Federal Communications Commission is currently considering a proposal, by Google and other tech players. It would allow tech companies to build electronic devices that transmit wireless internet signals over the "white spaces," or the vacant holes in the broadcast television band. "We have an ambitious goal called pervasive connectivity through ubiquitous broadband networks," said Page... more
The long rumored reorganization of the telecommunications sector in China has begun. Now China will have three major companies, each with both mobile and fixed networks. The focus for fixed network growth is broadband Internet access. The focus for mobile will be continued growth in mobile subscribers and the launch of 3G services, with the three companies using three different 3G technologies. more
Just about everyone I talk to is very excited about mobile Internet. In 2006, the Japanese government proudly announced that more people used the Internet through their mobile phones than through their computers. Online services are all talking about their "mobile strategy" and VCs are flocking to fund the latest "mobile startup". I don't think there is anything wrong with mobile or with some of the great new mobile applications and devices, but we have to be careful to remember that most mobile networks that actually work are built on infrastructure that is operated by a small number of mobile operators who use a lot of regulated and closed technology... more
There is a germ of truth (perhaps a prion-sized germ or maybe just an amino acid) in the idea that transmitters in "white spaces" in the TV band *might* disrupt patient monitoring equipment if designed by a lunatic who believes in sending massive pulses of energy in a whitespace in the TV band (perhaps amplified by a large parabolic dish antenna the size of a trashcan lid or larger, aimed at the patient monitor system. But that risk is completely shared with zillions of other potential radiators of energy in the entire electromagnetic spectrum... GE, of course, owns NBC. There is a MAJOR conflict of interest at the corporate level of GE... more
The new Clearwire could be game-changing, but the rules of the game may not be quite as Clearwire presents them. I have been wondering since last July whether something significant would happen in the Google/Sprint world. The deal announcement earlier this weekseems to be that key development... In a nutshell, Sprint will contribute its substantial spectrum licenses in the 2.5 GHz range and its WiMAX-related assets and intellectual property. Google, Intel, Comcast, Time Warner Cable, and Bright House Networks will invest a total of $3.2 billion. more
I see and hear a lot of confusion about next generation networks (NGN). In most cases people are using the term roughly as the ITU-T defines it: "A Next Generation Network (NGN) is a packet-based network able to provide services including Telecommunication Services and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies." but many people don't realize how little this has to do with the Internet... more
About 300 people attended to the net neutrality hearing Thursday hearing which began with testimony from Larry Lessig, a Stanford Law School professor and founder of the Center for Internet and Society... The meeting was called by the FCC in reaction to the news that US net firm Comcast had been exposed as managing traffic by stopping some of its 13m customers uploading files to BitTorrent and other peer-to-peer networks. The FCC has started a formal investigation to see if Comcast merits a fine for its actions. more
Bell filed its response to the Canadian Association Of Internet Providers (CAIP) submission to the Canadian Radio-television and Telecommunications Commission (CRTC) on its throttling practices yesterday, unsurprisingly arguing that its actions are justified and that there is no need to deal with the issue on an emergency basis. Several points stand out from the submission including its non-response to the privacy concerns with deep-packet inspection... and its inference that P2P usage could be deemed using a connection as a "server" and therefore outside the boundaries of "fair and proportionate use" under typical ISP terms of use. more
Today one of the headlines in Computer Sweden was that there is a dispute between Telia and the regulator PTS in Sweden. PTS requires Telia to stop locking out competing TV-distribution companies for IP-TV in the access network (DSL) that Telia runs. Specifically, they lean towards the fact Telia is dominant provider of the copper, and require Telia to competitors give access to the larger frequency band in the copper that they claim is needed for TV distribution. more
Modern travel means interminable waits, but it's a good time for reading. I finally read Wireless Pittsburgh: Sustainability of Possible Models for a Wireless Metropolitan-Area Network by Jon M. Peha, published in February as a working paper of the New America Foundation. The good news: it's full of interesting cost estimates and projected subscriber take rates based on specific demographics in Pittsburgh, Minneapolis and Philadelphia... The flaws in this study...

Going backwards upside down. That's what we're doing with telecommunications policy in the U.S. The Comcast affair should prompt a re-examination of many decisions the FCC, Congress, and the courts have made over the last few years. When the FCC reports on its reactions to Comcast's activities, the right response will be "You're asking the wrong question." "What is reasonable network management" isn't the question we should be asking... more
