Transformation - the Real Business Case for NFV and SDN

2016 has seen a steady flow of announcements on successful Network Functions Virtualization (NFV) Proof-of-Concept deployments, mostly focused on virtualizing Customer Premise Equipment (vCPE). This has been a relatively straight forward starting point because unlike many other NFV applications, the vCPE use case does not involve complex activities like having to scale in or out individual services. more

VDSL Cabinet Consideration for FttN Roll Outs

Australia will be an interesting test market for VDSL. With a new government and the broadband infrastructure company NBN Co basically in agreement, it is most likely that VDSL will be used to bring for example fast broadband to multi-dwelling units (MDUs). It was mainly for political reasons that the previous government stopped NBN Co deploying the VDSL technology in MDUs for this purpose. Whether or not any more VDSL will be deployed beyond that will largely depend on the NBN Co review of its current plan.  more

Cord-Cutting on Continued Rise - New Findings Suggest Quarter of US Households Now Without Cable

One-Quarter of US Households Live Without Cable, Satellite TV Reception, according to new GfK Study: "New findings from GfK show that US TV households are embracing alternatives to cable and satellite reception. Levels of broadcast-only reception and Internet-only video subscriptions have both risen over the past year, with fully one-quarter (25%) of all US TV households now going without cable and satellite reception. more

Can SpaceX Launch 30,000 Second-Generation Starlink Satellites? Maybe

The bottom line is that success is not guaranteed, but neither is failure -- there is a non-zero probability of success. On May 26th, SpaceX applied for permission to launch 30,000 "second-generation" Starlink broadband Internet satellites. (Note that the software on Starlink satellites is updated about once a week). The application narrative states that the second-generation satellites will be configured... more

The U.S. Fiber Expansion Craze

I've written several times recently in blogs that there is a growing backlog in buying fiber cable. Some of the backlog is due to the general supply chain malaise that seems to be affecting almost everything we buy. During the recent gas shortages in North Carolina, I found out that there is a shortage of truck drivers. Apparently, many truck drivers found something else to do during the pandemic, and now there is a shortage of drivers to deliver the many goods that are shipped by truck. more

2nd FCC Workshop on PSTN Transition Streaming Live Today

Today, December 14, 2011, the US Federal Communications Commission (FCC) is holding the second of two workshops on the transition of the PSTN to new technologies. The workshop started streaming live this morning at 9:30am US Eastern. The FCC's note about the workshops mentions that people watching the live stream can send in questions to panelists using either of two methods... more

NANOG 65 Report

NANOG 65 was once again your typical NANOG meeting: a set of operators, vendors, researchers and others for 3 days, this time in Montreal in October. Here's my impressions of the meeting... The opening keynote was from Jack Waters from Level 3, which looked back over the past 25 years of the Internet, was interesting to me in its reference to the "Kingsbury Letter". more

Watching North Korea’s Internet Connectivity Go Up and Down Via Twitter

One thing I enjoy about following Dyn Research (formerly Renesys) on Twitter is that they provide quite interesting graphics and charts about Internet outages. They've been tracking North Korea's Internet access quite closely over the past week and their tweets have been quite enlightening. Back on December 22, for instance, DynResearch tweeted a chart showing a 9-hour, 31-minute outage... more

Telesat Begins Testing Low-Earth Orbit Satellite Internet Service

SpaceX and OneWeb get a lot of publicity and have ambitious plans, but Telesat is the first low-Earth orbit (LEO) satellite Internet service provider to begin testing with potential resellers. Last January, Telesat launched a demonstration satellite and it is now ready for testing. Maritime connectivity provider OmniAccess and Australian ISP Optus had committed to testing the system previously and this week they were joined by in-flight entertainment company Global Eagle Entertainment. more

Is the Defense Innovation Unit’s Hybrid Space Architecture the “ARPANET” of Space and Will It Run on Aalyria Spacetime?

The goal of the Defense Innovation Unit (DIU) of the Department of Defense is to strengthen our national security by accelerating the adoption of commercial technology throughout the military and strengthening our allied and national security innovation bases. Space is one of its areas of focus and two of the space "lines of effort" are multi-orbit operations and logistics and hardware-to-software transformation modernization. more

Undersea Cable Cuts, Internet Governance, and Lessons Learned

Early this month I attended the 3rd Internet Governance Forum in Hyderabad, India. The overall theme of the 4-day meeting was "Internet for All"... Last Friday, I spent a couple of hours in the morning on email before I got cutoff around 10am. I have 2 DSL lines at home through 2 different ISPs, I tried both lines but they were both down. I thought something wrong happened at the local exchange and decided to turn off my computer and enjoy my weekend. The last thing I could have thought about then was that what happened back in January 2008 was happening again in less than a year! more

Emerging Markets Tech Watch 2012

2011 has been a significant year for the technology sector globally. Information technology is touching more people in more ways than ever before. Developed markets will be considering a 2012 in which business innovation, competitiveness, and service differentiation are built on ubiquitous broadband, cloud computing, smarter mobile computing, and an increasing plethora of Internet-connected devices. By contrast, securing the technology future for developing markets demands that attention be placed on more fundamental issues. more

The IPTV Growth in South Korea

At the beginning of 2008, the South Korean government passed a law that allowed telecoms operators to broadcast programmes in real-time over their broadband networks. The KCC awarded IPTV licences to KT Corp, Hanaro Telecom and LG Dacom. KT was banking on real-time Internet TV services because growth in the traditional broadband and telephone markets had slowed. The company planned to invest more than KRW1.7 trillion (US$1.5 billion) in IPTV services by 2012 as part of efforts to cultivate new sources of revenue. more

Amazon’s Orbiting Infrastructure

I have been following satellite Internet service since the 1990s, but I was surprised when I learned last week that Amazon had filed an application for a 3,236-satellite constellation of low-earth orbit Internet service satellites - Project Kuiper. I shouldn't have been surprised - Amazon was an infrastructure company from the start. In his first post-IPO letter to shareholders in 1997, Jeff Bezos pointed out that their distribution center capacity grew from 50,000 to 285,000 square feet and said their goal remained... more

Unintended Consequences of Submarine Cable Deployment on Internet Routing

The network layer of the Internet routes packets regardless of the underlying communication media (Wifi, cellular telephony, satellites, or optical fiber). The underlying physical infrastructure of the Internet includes a mesh of submarine cables, generally shared by network operators who purchase capacity from the cable owners. As of late 2020, over 400 submarine cables interconnect continents worldwide and constitute the oceanic backbone of the Internet. more
