Purpose vs Discovery and the Internet as a Dynamic

I'm writing this in response to the myriad discussions about how to make sure that the Internet continues to "work" despite P2P or whatever the current threat seems to be. Behind much of the discussion is the presumption that the Internet has a purpose in the sense of making some applications like video games and VoIP work. Yesterday we feared modems, today we fear P2P. more»

Ambient Connectivity: An Introduction

"Ambient Connectivity" is the ability to assume connectivity anywhere and anytime. Ambient Connectivity is the future of the Internet once we've removed the barriers we associate with today's telecom and extend the reach beyond the narrow confines of "broadband". The nuanced definition of Ambient Connectivity is that we can view connectivity as infrastructure but we need to take responsibility if we find ourselves disconnected. more»

Happy Birthday, Internet!

Oh, Internet. You had such potential when you were born — darling of the research community, supported by the wealthiest military the world has ever known. And you married well, into a powerful merchant family. Why are you so lost? Is it a midlife crisis? You were born, some say, 40 years ago this week in a lab at UCLA — one of ARPA's many children. It wasn't until nearly two months later that you first spoke, transmitting the letters "L" and "O" before crashing... more»

Seeing the Opportunity for IP Communications Within the Smart Grid Space

Having followed IP communications as an analyst since 2001, I've seen a few cycles come and go, and Smart Grid reminds me a lot of VoIP. Telcos and utilities both operate large, complex and costly networks, and prior to 1984, both were heavily regulated. Following the deregulation of telecom came a wave of unprecedented innovation and disruption built largely around IP technologies. We all know what that's done for telcos -- and communications in general. more»

Google Wave: Good News or Bad News for Carriers?

The recent launch of Google Wave generated a lot of attention, and for good reason. It's recently crossed my path in a few different settings, and while the news is still fresh, there is a lot here for service providers to be thinking about. At a high level, Wave is Google's entry into the real time collaboration space, and being Web-based, is poised to disrupt the status quo, not just for vendors, but service providers as well. more»

A Tribute to the Father of the RFC, Dr. Stephen D. Crocker

40 years ago the Request for Comments (RFC) process for the Internet was born. The RFC process continues to be the way Internet protocols are expressed today. We have one very special man to thank for this and his name is Dr. Stephen D. Crocker. He has played a key role in shaping the modern day Internet. For this, I felt that a special tribute to him was in order as we take a look at his countless contributions from the foundation of the Internet to the Internet as we know it today. more»

Gmail and IMAP and BlackBerry (Oh, my!)

When I was employed, I ran my own mail server and my own BlackBerry Enterprise Server, and I had things tuned pretty much exactly as I wanted them. My incoming mail got some custom processing that looked the sender's address up in my address book and assigned the message a category... I was a very happy email user. Now that I'm on my own, I've decided not to run my own server and all that software, and I've switched to Gmail and the T-Mobile BlackBerry server... Surprisingly, though, I'm mostly still happy... more»

Memo to John Markoff: There are No "Do Overs" in History

Think for a moment of the enduring legacy of African slavery in America. Think of the way it tainted this country's culture and politics; think of the bloody Civil War, the ghettos... What if we could roll back the clock and ensure that our society was "designed" so that slavery was never permitted and never happened? ... But what if I told you that my computer science lab was working on a "new Internet" that would solve all the terrible security and privacy problems of the existing one? Would you find this claim more credible than a proposed retroactive solution to the problem of slavery? more»

IPv6 Floating on the Ethernet

Remarkable how Ethernet has evolved and been widely adopted over this quarter of a century period extending its reach from LAN to MAN to WAN and from 10meg to 10gigE. One has to credit the IEEE for quite an efficient job as a standards body. Over in the IP world, this month of March will see IETF 74 meet in San Francisco and continue to ponder transitions, address translations, double translations, even carrier grade translations... more»

Who Pays for Email?

An acquaintance wondered why the people who run the systems that receive mail get to make all the rules about what gets delivered. After all, he noted: "The sender pays for bandwidth and agrees to abide by the bandwidth provider's rules." It is useful to think of the Internet as a collection of tubes, all leading from the periphery to the middle, where the middle is approximately "the peering point." The sender has paid for the tubes leading from himself to the middle... more»
