US Smart Grid Networks Exploiting Infrastructure to Provide Wireless Broadband

The USDA Rural Development's Rural Utilities Service (RUS) has now spent the $250 million committed for smart grid technologies. To this has been added an additional $201 million in funding approved by the Agriculture Secretary to electricity utilities in eight states to install smart grid technologies and improve their generation and transmission facilities. The beneficiaries are spread among a large number of states. more

The Spamhaus Distributed Denial of Service - How Big a Deal Was It?

If you haven't been reading the news of late, venerable anti-spam service Spamhaus has been the target of a sustained, record-setting Distributed Denial-of-Service (DDoS) attack over the past couple of weeks... Of course, bad guys are always mad at Spamhaus, and so they had a pretty robust set-up to begin with, but whoever was behind this attack was able to muster some huge resources, heretofore never seen in intensity, and it had some impact, on the Spamhaus website, and to a limited degree, on the behind-the-scenes services that Spamhaus uses to distribute their data to their customers. more

IPv6: SAVA, Ca va pas?

Sender Address Validation and Authentication (SAVA) is the silver bullet. It will send to Cyberia all dark forces that make us shiver when we make a purchase on the internet, pose a threat to our very identities and have made DDoS a feared acronym. Some of you will remember the heated debates when Calling Line Identification (CLID) was first introduced in telephony. Libertarians of all stripes called passionately to ban such an evil tool... more

The End of HFC and FttN Networks is Approaching

In the global telecoms industry, it looks as though 2013 will be remembered as the year when construction of new greenfield HFC networks came to a halt. Of course, there will still be upgrades to existing networks but the cost of fibre deployment -- linked to its much lower operational cost -- is now convincing cablecos and telcos alike to build new fibre networks wherever possible. This is not necessarily directly driven by customer demand, but by network costs and network efficiencies. more

No Free Super WiFi, But the US Still Needs Improved WiFi Coverage

The FCC has long battled for a more efficient deployment of unused spectrum, endeavouring to adapt rules governing 'white space' TV spectrum (largely gifted to broadcasters years ago, and generally in the 700MHz band) to newly released spectrum (in the 600MHz band). This will considerably improve wireless broadband coverage where it is needed most... Certainly, in the US's disjointed broadband sector there are considerable challenges ahead... more

Reducing the Risks of BYOD with DNS-Based Security Intelligence; Part 1: Understanding the Risks

Ah, BYOD. How I love thee. BYOD, or "Bring Your Own Device", gives me choices. I can use a device at work I actually like and am most effective with. (How did I ever get by without my iPad?) But BYOD comes with challenges. Personal devices can be infected with malware. Once they're connected to an enterprise's network, they can be controlled by a bot master to hijack enterprise resources and wreak havoc as part of a botnet. more

Addressing 2012: Another One Bites the Dust

Time for another annual roundup from the world of IP addresses. What happened in 2012 and what is likely to happen in 2013? This is an update to the reports prepared at the same time in previous years, so lets see what has changed in the past 12 months in addressing the Internet, and look at how IP address allocation information can inform us of the changing nature of the network itself. more

IPv6 Presents a Security Paradox for the Network

The capabilities IPv6 provides will enhance online security, but the shift to the new Internet address scheme may also present risks if not properly managed. Previously, Internet security was largely an after-thought for the early Internet, as its primary purpose was to facilitate open, end-to-end, any-to-any communications and information exchange for bridging and accelerating research efforts. Today, we have a much more complex online ecosystem that spans billions of users across the globe and serves not only as an engine for e-commerce, but as an engine for all commerce. more

To Flat or To Cap?

I don't think it's a surprise to anyone, but it's the Christmas season again and doubtless a large number of television sets will be sold as part of the annual retail festivities. But these days the devices for sale in the shops are not just televisions: today's television is perhaps better described as a media computer with a very large display. Sure, the device can tune in to radio transmissions and display them... but the device also is equipped with either a WiFi or an Ethernet jack, or both. This alone sounds like a relatively innocuous addition to the television, but it's providing to be a highly disruptive change in the traditional Internet market space. more

IPv6: A 2012 Report Card

The Gogonet Live conference in San Jose witnessed outstanding presentations by several federal administrations including Veteran Affairs, NASA and SPAWAR, sharing their experience and progress towards IPv6 adoption. Furthermore, the NIST compliance report leaves no agency any place to hide. The report card is there for everybody to see. In spite of regular jabs and criticisms, the US Federal Government has done a remarkable job. more

Google Fiber: Technology Innovation Or Revenue Assurance?

Google's announcement of its 'Fiberhoods' throughout Kansas City is yet another example of the thought leadership and innovation being brought forward by the popular advertising company. But what does this move say about the state of Internet access in America? more

IPv6: Don’t Forget About Your Switches!

When preparing a network for IPv6, I often hear network administrators say that their switches are agnostic and that there is no need to worry about them. Not so fast. Yes, LAN switches function mainly at layer 2 by forwarding Ethernet frames regardless of whether the packet inside is IPv4 or IPv6 (or even something else!) However, there are some functions on a switch that operate at layer 3 or higher. more

Google’s Secret Strategy With the Kansas City Fiber Project

I have long been perplexed at how Google plans to make a profit with their Kansas City Fiber project. Originally the project was touted as an altruistic move by Google to really understand the underlying costs of deploying fiber in a large municipality. But as anyone who has been in the trenches can tell you, it is not the technology that determines the cost of a fiber deployment, but the tyranny of the take-up. more

Occam’s ITRs

It's been a quarter of a century since the world's governments convened to draft up a common set of regulations about the conduct of international telecommunications. In December of 2012 the world's governments will convene to reconsider these regulations, to hopefully sign an updated set of regulations. This time around, this activity is generating considerable levels of public interest. Congressional hearings in the United States have been held, and various pronouncements of intent from various governmental, regional, and industry groups have been made. more

IPv4: Business As Usual

This year, we expect that the RIPE NCC's pool of unallocated IPv4 addresses will reach the "last /8", meaning that we have 16,777,216 IPv4 addresses left in the available pool. At that point it will no longer be possible for RIPE NCC members to obtain the amount of IPv4 addresses they will require to expand their current and future networks. When we hit the last /8, the RIPE NCC will only be able to distribute IPv6 addresses and a one-off allocation of IPv4 address space... Has this caused a last minute rush? more
