Why the Opus Codec Matters - Even if You Don't Care About Audio

What makes the Opus codec so interesting? Why is there such a buzz about Opus right now? If you are not in telecom or doing anything with audio, why should you even remotely care about Opus? In a word... Innovation! And because Opus has the potential to let us communicate with each other across the Internet with a richer and more natural sound. You will be able to hear people or music or presenters with much more clarity and more like you are right there with them. more»

Video: Have We Found the Cure for Bufferbloat?

Following up on my recent post about how solving the Bufferbloat problem could dramatically increase the speed of Internet usage, I recently learned via a Google+ post by Michael Richardson of this video of a presentation by Jesper Dangaard Brouer of Red Hat at the recent Brno 2013 titled "Beyond the existences of Bufferbloat - Have we found the cure?" more»

Live Today - "IPv4 Exhaustion and the Path to IPv6" from INET Denver

If you are interested in the current state of IPv4 address exhaustion within North America as well as the current state of IPv6 deployment, there will be a live stream today, April 17, of the sessions happening at INET Denver starting at 1:00pm US Mountain Daylight Time (UTC-6). The event is subtitled "IPv4 Exhaustion and the Path to IPv6" and you can view the live stream at. more»

The International Space Station's Canadian Music Video Collaboration - and Google+ Hangout

As much as we talk here about the inner workings of the Internet's infrastructure, there are times when you have to just sit back and look at how incredibly cool some of the things are that are enabled by the Internet. For example, last week I was delighted to stumble across this excellent music video collaboration between the International Space Station's Canadian commander Chris Hadfield, the Canadian band Barenaked Ladies along with a Canadian student choir. more»

The Future of Home Networking: A Problem Statement

I'm a network engineer, and like many engineers I often gravitate to the big projects; large networks with problems of scale and complexity in my case. However, I also consider myself a student of Occam's razor and often quote Antoine de Saint-ExupĂ©ry: "perfection is reached not when there is nothing left to add, but when there is nothing left to take away." In this spirit of "less is more" I have recently become intrigued by the problems appearing in home networking. more»

IETF 85 Begins Next Week In Atlanta - Here Is How To Follow Along

The 85th meeting of the Internet Engineering Task Force (IETF) begins next week in Atlanta, Georgia, USA. Over 1000 engineers, maybe as many as 1400 or more, from all around the world will gather in various working groups to discuss and debate issues relating to the open standards that define the Internet's infrastructure. more»

IETF Working on HTTP 2.0, Will be Based on Google's SPDY Protocol

With an eye toward updating the World Wide Web to better accommodate complex and bandwidth-hungry applications, the Internet Engineering Task Force has started work on the next generation of HTTP (Hypertext Transfer Protocol), the underlying protocol for the Web. more»

Internet Society Releases Paper on "What Really Matters About the Internet"

Internet Society has released a paper today highlighting the importance of understanding what is important and unchanging about the Internet. more»

Update on AS Path Lengths Over Time - How Interconnected is the Internet?

With the number of ASes connected to the Internet constantly increasing, one could expect that the length of the AS paths would also increase as the network as a whole gets wider. However, this doesn't seem to be the case. Also, with IPv6 being more widely deployed, how does the interconnectedness of the IPv6 portion of the Internet compare to IPv4? more»

Leading Global Standards Organizations Endorse 'OpenStand' Principles

Five leading group of global organizations - IEEE, Internet Architecture Board (IAB), Internet Engineering Task Force (IETF), Internet Society and World Wide Web Consortium (W3C) - today announced that they have signed a statement affirming the importance of a jointly developed set of principles establishing a modern paradigm for global, open standards. The group have invited other standards organizations, governments, corporations and technology innovators globally to endorse the principles. more»

OpenFlow - The Programmable Network Revolution

Over the past few months I have made regular references to OpenFlow. This is an exciting new development that fits in very well with several of the next generation technology developments that we have discussed in some detail over the past few years -- new developments such smart cities and smart societies, the internet of things. Such networks need to operate more on a horizontal level, rather than the usual vertical connection between a computing device and the users. more»

Who Says You Can't Have Fun at The IETF?

A new IETF draft has been published that specifies a new HTTP status code for legally restricted resources. That is, if the government restricts your access to the web page, return this code (similar to how something not found is a 404). The error code: 451. From the Internet Draft, if the user tries to access a page, but access to the page is restricted by the government, display the following... more»

WebRTC/RTCWEB Congestion Control Workshop on July 28 in Vancouver

As we start moving more real-time communications into web browsers with the upcoming WebRTC/RTCWEB offerings, what do we do about congestion control? How do we ensure that all these browser-based communications sessions share the network fairly? With RTC capabilities now already available in builds for browsers such as Google Chrome and Mozilla Firefox, how do we deal with the expected increase in voice, video, chat and data traffic? more»

Do We Need An IPv6 Flag Day?

In recent interviews about World IPv6 Launch I've been asked by several different people whether or not I think there needs to be some kind of a "Flag Day" on which the world all together switches from Internet Protocol version 4 (IPv4) to the version 6 (IPv6). I don't think a flag day is needed. World IPv6 Launch is just the right thing. It's worth looking at some previous flag-type days to get a better sense of why. more»

World IPv6 Launch: Now What?

World IPv6 Launch kicked off 6 June 2012 at 00:00 UTC. On this day, multitudes of website operators, network operators and home router vendors from all over the world have joined thousands of companies and millions of websites in permanently enabling the next generation Internet. They have done this by turning IPv6 support on by default in (at least some of) their products and services. This is a major milestone in the history of the Internet. more»
