In response to customer feedback, Time Warner Cable has discontinued its trials of tiered Internet service. [Corporate Announcement here.] It was quite a stuff-storm, but to TWC's credit, they put their finger up, felt the howling gale, and changed course right away. This is in marked contrast to their larger competitor, Comcast... more
As widely reported, Credit Suisse analysts have estimated Google's YouTube may lose $470M in 2009 and more in the future. However, their estimates say Google will pay $360M for bandwidth in 2009. I don't know how Google figures their cost of bandwidth, but anyone who understands anything about Internet transit/peering knows Credit is way off base. more
The ongoing witch-hunt from the incumbent telcos in the USA against municipalities that are trying to build their own broadband networks is continuing unabated. This is nothing new... With the economic crisis there has been a new focus on regulatory rules and the importance of the common good, next to the free market. However that message has not yet got through to the incumbent players in the USA. more
Wuhan in 1911 led the revolt that overthrew the Qing Dynasty and now hopes to dethrone the world's fiber leaders. China this year or next will surpass Japan as world fiber leader, with estimates as high as 30M homes connected. Wuhan's FiberHome is now #2 in the world according to Infonetics, ahead of Alcatel, Motorola, and Tellabs. more
In Europe yet another package is discussed, and it includes issues related to what I guess one could call Network Neutrality. And, as usual, at the end of the game, texts are negotiated that does not have much meaning in reality. Negotiations on what words imply, while I as an engineer have absolutely no idea what either of the parties actually mean... more
Earlier this month, I had the opportunity to attend the The Emerging Communications (eComm) 2009 conference in San Francisco which was packed with 3 days of fascinating conversations about the future of communications. I absolutely enjoyed talking to various speakers and attendees giving me a deep level of appreciation and perspective on technical, commercial and political issues at hand -- and what is likely to come in the next few years. And speaking of politics, Lee Dryburgh, who founded eComm in early 2008, has generously allowed us to share with you a fascinating panel discussion which took place on day 3 of the conference called "Spectrum 2.0 - What's really happening?" more
As founder and CTO of Ellacoya Networks, a pioneer in Deep Packet Inspection (DPI), and now having spent the last year at Arbor Networks, a pioneer in network-based security, I have witnessed first hand the evolution of DPI. It has evolved from a niche traffic management technology to an integrated service delivery platform. Once relegated to the dark corners of the central office, DPI has become the network element that enables subscriber opt-in for new services, transparency of traffic usage and quotas, fairness during peak busy hours and protection from denial of service attacks, all the while protecting and maintaining the privacy of broadband users. Yet, DPI still gets a bad rap... more
Many of us are familiar with network effects within telecommunications. Fundamentally, the notion is that as the number of participants in a network increases, the value of that network increases superlinearly. Though many different theories exist about how best to value these networks, the general idea is that the more people on a network, the more benefits accrue to everyone on the network... more
Mobile WiMAX, with the release of 2×2 MIMO chips in 2008, gives WiMAX a lead of two or so years on its major competitor -- the 3GPP's LTE. However, 3G cellphones using 3GPP UMTS technologies, extended to higher speeds with HSPA, is widely used in handsets in many countries. In North America, 3GPP2 CDMA2000 and EV-DO are widely used, but these are likely to be replaced over time by LTE and to some extent WiMAX. more
I've been posting photos and snippets during eComm 2009 this week, but composing my overall impressions has been another matter. Sitting through 3 days mostly filled with continuous 15 minute presentations is a surefire recipe to fry your brain, and most people I talked to were topped out well before things wrapped up Thursday night. It's information overload of the highest -- and best -- order... Here's my top-line takeaway, and reading the rest of this post is really just detail. But it's detail you'll probably love if you really want to know what you missed... more
