It’s Expo Eve down here in New Orleans, where the Ernest N. Morial Convention Center will soon fill with the technology people of the cable and broadband industry. Us included!
We’ve been planning for months for this year’s SCTE Cable-Tec Expo, and are appreciably stocked (I hope!) with all of the elements that multichannel video providers (MVPDs) need to satiate their capacity needs — and contribute to the industry’s overall industrial momentum.
If you’re not going, or not familiar with the cable/broadband industry’s biggest and most hard-core tech event — the short hand is that it’s all about Read More »

Within the coming decade, Internet Protocol version 6 (IPv6) will be key to enabling 50 billion connections among people, processes, data, and things in the Internet of Everything (IoE). But how we get there from here is not a simple matter.
I’m very pleased to invite Mark Townsley, Cisco Fellow and recognized industry expert on IP, to discuss this important transition in the second of our three-part blog series on IPv6. The first blog in Mark’s series was “Demystifying IPv6”.
Three years ago, I organized a conference in Paris where I thought it would be fascinating to bring together the original designers of IPv6 alongside the engineers who were finally deploying it at scale more than a decade later. During this discussion, Steve Deering, one of the “fathers” of IPv6 in the 1990s, was asked one of the most common questions about IPv6: Why wasn’t it designed for backward compatibility with IPv4? After all, wouldn’t it be easier to make the transition if the two versions could transparently coexist? Steve answered that the problem is not that IPv6 wasn’t designed to be backward-compatible—the real problem is that IPv4 wasn’t designed to be forward-compatible.
Steve was making the point that IPv4 was designed with a fixed address space. Given the number of computers connected to the Arpanet throughout the 1970s, this fixed-length address field seemed to be sufficient—at least for that version of IP. IP had been replaced before, and it seemed perfectly reasonable at the time that it might be replaced again. Read More »

Shortly before we released this year’s Cisco VNI Forecast 2012-2017* on May 29th, I had a chance to contemplate the implications behind all the report’s data. The Forecast makes it clear that IP traffic will continue to grow “in leaps and bounds” through 2017, but there is so much more information lying hidden within the report.
* an annual projection of global Internet Protocol (IP) traffic, now in its seventh year,
used by companies, analysts, media, academia, and governments wordlwide.
For a quick overview of this year’s findings, read Thomas Barnett’s VNI blog post.
Here are six significant conclusions that came about in my review of VNI’s findings and what they mean for the future functioning of the Internet: Read More »

Version 6 of the Internet protocol (IPv6) is a key enabler of the Internet of Everything (IoE). People, data, and things all need IP addresses to connect to the Internet. But we’ve already run out of IP addresses under IPv4, which dictates almost all (98.5 percent) of Internet traffic today. Even with all of the attention IPv6 has received, confusion and misinformation abound.
I’m extremely pleased to have Mark Townsley, Cisco Fellow and recognized industry expert on IP, explore IPv6 over a series of three blogs.
In these posts, Mark will demystify IPv6, discuss how to best make the transition from IPv4 to IPv6, and take a look “under the hood” of IP so that companies and industries can get the most value from IoE. Read More »

Visualize this: nearly half the Earth’s population – 3.6 billion people – connected to the Internet for communication, commerce, education, information, and entertainment. Think that’s too futuristic? Think again. By 2017, less than five years from today, that will be our reality.
This prediction is one of several key findings from the newly released Cisco Visual Networking Index, 2012-2017, a highly regarded annual forecast of global Internet Protocol (IP) traffic now in its seventh year.
Let’s explore further the Internet of 2017, as projected by the updated VNI Forecast.
By 2017, IP traffic volumes and regional growth will continue to impress: Read More »
