Internet Protocol / Most Commented

Psst - Interested in Some Lightly-Used IP Addresses?

The Internet Service Provider (ISP) community is carefully watching the impending depletion of the unassigned IPv4 address pool. Most estimates place the depletion of the central pool of unassigned IPv4 addresses by mid-2011. After that, each Regional Internet Registry (RIR) will continue to satisfy requests for additional IPv4 space for a limited time (depending on the rate of incoming requests and the amount of address space on hand in the RIR at the time of central pool depletion). more»

Cisco's Kevin Shatzkamer Discusses the Future of Mobile Video

Kevin Shatzkamer, Chief Architect for Cisco Mobility, speaks to the mobile research Cisco has developed in helping Mobile Service Providers reach their ROI goals and objectives in projecting an increasingly demand driven market. ... There has been speculation for years that increased demand for mobile video would tax and possibly crash current networks and infrastructures of mobile operators. A predictor may be The World Cup games held in South Africa. more»

Verizon Begins Testing IPv6 on FiOS Services

John Curran writes: Verizon has announced today that its "month-long trial of IPv6 involves FiOS-enabled customer homes with customized CPE -- provided by Verizon -- that can support both IPv6 and IPv4. The dual protocol setup will also be implemented on Verizon's edge gateway routers. Verizon employs 6PE technology, which uses IPv6-provider edge routers to connect across the company's IPv4 MPLS core. The IPv6 traffic is then sent over IPv6-capable peering connections." more»

Web at Twice the Speed: Google Reveals Information on SPDY Project

In a recent blog post, Google engineers have revealed information about an early stage project called SPDY (pronounced "SPeeDY"), aimed at significantly boosting Web download speeds. According to the post, SPDY is an application-layer based protocol designed for minimizing latency. It says: "So far we have only tested SPDY in lab conditions. The initial results are very encouraging: when we download the top 25 websites over simulated home network connections, we see a significant improvement in performance - pages loaded up to 55% faster. There is still a lot of work we need to do to evaluate the performance of SPDY in real-world conditions." more»

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»

IPv6 Key Part of Multi-Billion Dollar Smart Grid Projects

Carolyn Duffy Marsan of Network World writes: "Could Smart Grid, the Obama Administration's effort to modernize the nation's electric grid, be the killer app for IPv6? That's what Internet engineers are asking as they see billions of dollars in stimulus funds pumped into smart electric meters, automated utility substations and new sensors networks -- all of which could take advantage of the abundant address space and built-in security offered by IPv6, the long-anticipated upgrade to the Internet's main communications protocol..." 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»

Root Scaling Study Report is Out

Earlier this year, ICANN began to seriously consider the various effects of adding DNS protocol features and new entries into the Root Zone. With the NTIA announcement that the Root Zone would be signed this year, a root scaling study team was formed to assess the scalability of the processes used to create and publish the Root Zone. Properly considered, this study should have lasted longer than the 120 days -- but the results suggest that scaling up the root zone is not without risk -- and these risks should be considered before "green-lighting" any significant changes to the root zone or its processes. I, for one, would be interested in any comments, observations, etc. (The caveats: This was, by most measures, a rush job. My spin: This is or should be a risk assessment tool.) Full report available here [PDF]. 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»

Annual Global IP Traffic Will Exceed Two-Third of a Zettabyte in 4 Years

Annual global IP traffic will pass two-thirds of a zettabyte in four years according the Cisco's Visual Networking Index report. The economic downturn has only slightly tempered traffic growth and the global IP traffic is expected to quintuple from 2008 to 2013. Cisco predicts IP traffic to grow at a compound annual growth rate (CAGR) of 40%. more»

Oracle Announces Agreement to Acquire Sun Microsystems

Brandon Bailey reporting on Mercury News: "In a surprising twist, Sun Microsystems announced this morning that it will be acquired by Oracle in a deal worth roughly $7.4 billion, or $5.6 billion net after accounting for Sun's cash and debt. The news comes just a few weeks after earlier talks for IBM to buy Sun [link] collapsed..." 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»
