The New Clearwire

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

NGN is Not the Internet, and Never Will

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

FCC’s Stanford Hearing on Broadband Practices

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

Locking Out Competing Providers is Bad

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

Retrograde Inversion of Telecommunications Policy

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

Overloading the Internet? Recent Media Reports Based on Dangerous Misinformation

The London Times article (and a similar one in the Guardian) are based on dangerous misinformation. The net isn't slowing down, and nearly no technical experts believe major "overload" problems likely on the backhaul, core, or decent local loop... Net traffic per user, as documented by Odlyzko and Cisco, has been growing at about 35-40% the last five years, and that growth rate is flat and possibly down the last two years. The net has been able to handle the increase without price increases, much less overload, because the primary and rate limiting equipment (switches, routers, WDM, etc.) have simultaneously been going down at a similar 35-40%. Moore's Law is bringing costs down and capacity up at a remarkable rate. more

NY Times Grossly Misreads WEF Report

Today's New York Times includes an article by John Markoff entitled "Study Gives High Marks to US Internet." But either John Markoff is fuzzy about exactly what the Internet is or he didn't actually read the report. His title is way off base. He did interview a few people who are quoted in the latter part of the article, so there is some information in the article. But he's done a major disservice for the many who read only the title or perhaps first paragraph... more

F2C: My Opening Remarks

Here are my opening remarks at F2C: Freedom to Connect yesterday: "I am honored to be among so many remarkable people. We have to be remarkable people, because we have a hell of a job to do. The Internet has been given to us. It is a miraculous gift, and a boon to our lives... at least in part because it accidentally matured outside the purview of profit and loss. Now the money has arrived. If you want to see what happens when the money arrives, look at Nigeria or Venezuela or Russia or Iraq..." more

Google’s Gigabit Gambit

Want a gig (1000 megabits per second) of Internet access bandwidth? Google says you could have it by the end of next year "from Manhattan to rural North Dakota (sic, I think they meant Vermont)" if their proposal to the FCC is accepted forthwith according to CNET's newsblog. Not only a gig but a mobile gig, accessible by cellphone or roaming computer -- no fiber required. Sound too good to be true? -- it isn't, IMHO! Engineering is not the problem... more

700 MHz Auction Winners: Why Block C Matters

Today the FCC announced the winners of the 700 MHz auction -- and you can see from pp. 62-63 of this document that Verizon won Block C. (Block C was set up in two nationwide paired blocks of 11 MHz each, which were auctioned off in very large geographic areas -- 12 licenses, each covering a "Regional Economic Area Grouping". Verizon won seven of the twelve licenses, covering all of the US except Alaska, Puerto Rico, American Samoa, Guam, and the Northern Mariana Islands.) Why does this matter? more

Broadband Access: What Should We Regulate?

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

It’s March Madness Time and I Want My IPTV!

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

As the Comcast Saga Unfolds, Be Careful What You Wish For

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

Client-based WDS: Providing Application Acceleration in Mobile and VPN Environments

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

How Tiered Internet Pricing Could Actually Facilitate P2P

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
