Network Neutrality is a hot topic in the US. The FCC held hearings in my neighborhood recently (while I was in Asia). Now I see Professor Susan Crawford will be testifying next Tuesday at a House Judiciary Committee hearing on "Net Neutrality and the First Amendment." I look forward to her remarks, but I worry that the whole discussion will be focused on "IP Pipes," that is connectivity at network layer 3. This distracts us from the fundamental problem... more
IPTV is on the horizon. Maybe I watch too much basketball, but the first thing I pictured was turning my flat screen into a big PC-like monitor with multiple windows showing several games, and perhaps even checking email and trying to do a bit work in another (admittedly much smaller) window. You could drag and drop, expand or shrink the games to whatever size you wanted just like you do on a PC with applications. Since the source video could come from different geographical regions in the country, you could catch the NCAA game they are showing in your local region while also watching another game from another region... For some, IPTV is a reality. But for the most part deployments are limited. more
Comcast has been in the news recently for deliberately "slowing down" some subscribers and applications in its broadband cable service. There was an article in the Washington Post today updating the case, and there was a recent article in Network World that actually favors the groups filing the complaints and calls for the FCC to crack down on Comcast. more
Wide-Area Data Services (WDS), aka "WAN Optimization" is becoming the most effective way to improve application performance while reducing network traffic. In scenarios where there is significant network latency that would otherwise render many applications unusable, WDS can deliver almost LAN-like speed. Where bandwidth constraints exist and there is no practical or economical option, WDS can help reduce network traffic, allowing you to postpone or avoid circuit upgrades altogether. The technology provides the ability to centralize applications and servers, furthering the cost savings on hardware, software licensing, maintenance and the operation of a distributed architecture. more
Time Warner Cable's planned experiment with tiered charging for Internet access has generated a flurry of coverage in the blogsphere, but no new insights (at least that I've seen). The primary problem ISP's complain about is that 5% of their customers use 90% of the available bandwidth and when they examine this traffic, it's mostly peer-to-peer file sharing... more
It's Friday, a day to tie some threads together. There were three announcements/events this week that are connected in a non-obvious way... These three elements go together in creating a picture of US policy towards Internet access at the beginning of 2008. Rather than seeing the Internet as an engine for economic growth, creativity, innovation, and new jobs -- and as the converged communications medium for the next generation -- current policy is to wait for private companies to decide when investment in access makes sense for them. Those private companies have plenty of incentives to shape access to suit their own business plans. more
Telco front-man Scott Cleland, in a recent blog post, thumbs his nose at the Four Internet Freedoms and says that the FCC should too. Under current leadership, it probably will. Referring to the recent submissions to the FCC by Free Press and Public Knowledge and Vuze complaining about Comcast's use of reset packets to block applications that compete with Comcast's own proprietary video entertainment offering, Cleland says "Network management trumps net neutrality." There are lots of reasons for, ahem, managing. Cleland neglects to observe that controlling congestion the way Comcast does it is like scattering nails in the road for traffic control. more
The International Telecommunications Union recently issued a press release announcing with joy the release of "the first set of global standards for Internet Protocol TV (IPTV)." A key sentence: "A combination of voice, Internet and video services over a single broadband link and from a single provider is foreseen as the ultimate goal of the broadband revolution." Those of you who lived through 'What Is Broadband Good For?' with me last summer, know that the word "broadband" is a pet bugaboo of mine. It's a word that answers a lot of policy questions in a particular way. more
There has recently been some good and bad news about WiMAX. On the good news part, an announcement made by the WiMAX Forum this month regarding the launching of the Mobile WiMAX certification program through which vendors can get their IEEE 802.16e-2005 equipment tested and possibly certified... On the bad news part, there was the Sprint-Clearwire breakup after three months of announcing a plan to join forces in building a nationwide WiMAX network in the US. Although it is anticipated that each company would carry on with its own WiMAX plans, analysts believe that the breakup would have negative impact on WiMAX deployment in the US... more
In a counter-intuitive move for a Republican free marketeer, FCC Chairman Kevin Martin has sought to impose substantial additional regulations on cable television. Chairman Martin ostensibly can retain his credentials by claiming that a 1984 law requires the FCC to act when cable television systems serve 70% or more of the U.S. population and 70% who can subscribe do so. more
Let's say that providing communications infrastructure is an inherent function of a state. Most people think of the internet as a telephone system, and most people think the telephone companies aren't supposed to choose which calls will go through based on their content. People think that because they think internet access, like telephone access, is a utility -- like electricity conduit, water pipes, etc. -- that has something to do with the government, and the government isn't supposed to discriminate. more
When Rogers Communications began promoting its Rogers@Home high-speed Internet service nearly a decade ago, the company branded it "the Internet on Cable." Years later, their service, as well as those of their competitors, is gradually morphing into "the Internet as Cable" as broadcasters, Internet service providers, and cultural groups steadily move toward the delivery of content online that bears a striking resemblance to the conventional cable model. more
There is growing interest in the US for the FCC to look at White Space to enable more options for broadband wireless in rural areas. What is White Space? Last weekend, the Sunday NY Times published an article about wireless services that included this description: "In many areas, not all broadcast [television] channels are in use. The unused channels are "white spaces" of high-quality spectrum that could be made available to local Internet service providers. Unlike the much higher frequency of Wi-Fi, television broadcast frequencies can travel for miles and penetrate walls, providing a much broader range for Internet service." There is a coalition of eight technology companies driving the discussion in the US... more
I've been reading the kerfuffle around Comcast's blocking of various random network protocols with interest. Whilst I remain convinced that blanket "network neutrality" legislation remains just a form of digital gripe water (cures colic for cybernauts), there's clearly a problem. As I previously alluded there's a definite consumer protection issue over what you buy when it says 'Internet' on the tin. So here's tuppence worth of additional input... more
Once we decide that Network Neutrality is a good thing to (re)enshrine in law, then we need to ask how to do that effectively. One way would be to pass a law saying, "Thou shalt not discriminate." That's the current approach. But network operators will say that they must manage their network, and if, in the course of network management, they were to disadvantage some source, destination, application, service or content, they might be accused of violating the law. So any Network Neutrality law must have a Network Management Exception... more
