Video: Jim Gettys on #Bufferbloat @googletalks #Internet
A Google Tech Talk from April 26, 2011 from Jim Gettys of Bell Labs. Jim is well-known as one of the original developers of the X Window System, and has long been active in open source and internet standards. His recent experiences with immersive telepresence applications exposed systemic implementation errors in many Internet buffer and queue designs. He describes the journey of discovery in this talk.

Fast Company interviews @InternetSociety’s Lynn St. Amour on future of #Internet #INETny
On May 26 2011 Fast Company, as part of their futurist Crystal Ballin’ series, published an interview with Internet Society President Lynn St. Amour Envisioning The Omnipresent, Benevolent Internet Of The Future. Rather than “series of tubes” St Amour sees the Internet as a “series of building blocks”..Some have suggested in the past that the Internet just wasn’t built to handle the vast structures it supports today, and that for security reasons, we ought to just scrap it and start over. Do you think that’ll ever happen?
I think any notion that scraps the Internet and starts from a clean slate is just a non-starter; we won’t be scrapping this Internet for many, many decades. That’s not to say there won’t be other Internets or other structures that both build on and evolve from this one. The Internet is basically a series of building blocks that allow future Internets and future applications. Cybersecurity often does mean a hardening down or locking out, under the guise of protection, but our advice is really to lean in to the real core of what’s made the Internet the Internet–its openness, its resiliency.
Lynn St Amour will, of course, be moderating the closing Cerf/Berners Lee/Strickling discussion at INET New York on June 14.

Towerstream announces Manhattan WiFi network #nyc #broadband #WiFi
According to Bloomberg WiMax ISP Towerstream has announced a scheme to install a network of about 1,000 outdoor wireless routers in Manhattan, and sell ‘hand off’ access to the system to wireless carriers to cover service gaps. The article states:During a demonstration recently on the corner of West Broadway and Broome Street in New York’s SoHo district, an iPhone’s data speed leapt from .35 megabits per second to 26 Mbps.
Noting that the routers will cost $800 and Towerstream will pay up to $1k/month to rent locations the article details an earlier test of 200 routers:
Without any promotion, the network handled 20 million Web sessions by consumers who happened to spot Towerstream when trolling for a Wi-Fi connection. That’s a fifth of the Wi-Fi traffic generated by AT&T during the same three months at its hotspots, which include most Starbucks and McDonald’s.

Cisco predicts 400% growth in global IP traffic by 2015 #Internet #VNI
Cisco’s Virtual Networking Index, in a report Entering the Zettabyte Era (pdf) issued today Jun 1 2011, predicts that annual global IP traffic (Internet and non-Internet) will grow 400% by 2015 to reach 966 exabytes or nearly 1 zettabyte. The chart below represents Internet traffic.
Other predictions for 2015:
- There will be 3 billion global Internet users, with average bandwidth of 27mbps.
- The number of devices connected to IP networks will be twice as high as the global population.
- There will be 6 million Internet households worldwide generating over a terabyte per month in Internet traffic, up from just a few hundred thousand in 2010 (but most of them will be in Asia).
- Traffic from wireless devices will exceed traffic from wired devices.
- Peak traffic will be equivalent to 500 million people streaming a high-definition video continuously.
Over 60% of the traffic will be video, broken down as follows:
Interestingly the report tackles the topic of possible changes to the asymmetric bandwidth status quo:
With the exception of short-form video and video calling, most forms of Internet video do not have a large upstream component.
As a result, traffic is not becoming more symmetric as many expected when user-generated content first became popular. The emergence of subscribers as content producers is an extremely important social, economic, and cultural phenomenon, but subscribers still consume far more video than they produce. Upstream traffic has been flat as a percentage for several years, according to data from the participants in the Cisco VNI Usage program.
It appears likely that residential Internet traffic will remain asymmetric for the next few years. However, there are a number of scenarios that could result in a move toward increased symmetry.
• Content providers and distributors could adopt P2P as a distribution mechanism. There has been a strong case for P2P as a low-cost content delivery system for many years, yet most content providers and distributors have opted for direct distribution, with the exception of applications such as PPStream and PPLive in China, which offer live video streaming through P2P, and have had great success. If content providers in other regions follow suit, traffic could rapidly become highly symmetric.
• High-end video communications could accelerate, requiring symmetric bandwidth. PC-to-PC video calling is gaining momentum, and the nascent mobile video calling market appears to have promise. If high-end video calling becomes popular, this will move traffic toward symmetry again.Generally, if service providers provide ample upstream bandwidth, applications that use upstream capacity will begin to appear.
