Resource Public Key Infrastructure (RPKI) is a method to secure internet routing traffic by cryptographically verifying routes. As we begin 2022, we look back at 2021 and see how the year saw another significant step towards its adoption. High-profile issues with the old trust-based model of Border Gateway Protocol, designed several decades ago, have shown the continued importance of protecting popular networks from mistakes or hackers. more
Every year I write a blog talking about the trends that I think we're likely to see in the coming year. But 2021 was such an unusual year for all of us that I thought it would also be useful to talk about what we accomplished in the industry over the last year while fending off a pandemic. All in all, it was quite a year. more
The non-stop wireless industry claims that we've moved from 4G to 5G finally slowed to the point that I stopped paying attention to it during the last year. There is an interesting article in PC Magazine that explains why 5G has dropped off the front burner. The article cites interviews with Art Pouttu of Finland's University of Oulu about the current state and the future of 5G. That university has been at the forefront of the development of 5G technology and is already looking at 6G technology. more
The United States and its allies are in a technology cold war with China and its allies. This is evidenced by major battles like the US ban on Huawei and China's drive for technological independence and their global infrastructure program to create a digital silk road. (The cold war began under Trump, but President Biden is continuing it). There are other, less well-known battles like the battle over optical communication in space. more
Last year, I reported on the possibility that LEO (Low Earth Orbit) satellite-based systems might be a gamechanger for the delivery of high-speed data services, including internet access, to people in regional and remote Australia. What has become clear with the rollout of the NBN is that the quality of data connections in metropolitan cities in many cases has improved, but that the rest of Australia doesn't have a similar experience. more
One of the first in-depth reviews I’ve found for T-Mobile’s fixed cellular broadband was published in the Verve. It’s not particularly flattering to T-Mobile, and this particular customer found the performance to be unreliable – fast sometimes and barely functioning at other times. But I’ve seen other T-Mobile customers raving about the speeds they are receiving. We obviously can’t draw any conclusions based upon a single review by one customer... more
There is no such thing as a 25/3 Mbps broadband connection, or a 100/20 Mbps broadband connection, or even a symmetrical gigabit broadband connection on fiber. For a long list of reasons, the broadband speeds that make it to customers vary widely by the day, the hour, and the minute. And yet, we've developed an entire regulatory system built around the concept that broadband connections can be neatly categorized by speed. more
It's that time of the year for me to get out the crystal ball and peer into 2022... I have no idea why it took a year for the administration to tee up a new Chairman and recommend a fifth FCC Commissioner. But once a new Commissioner is seated, the new FCC will tackle reinstating some version of Title II regulation, accompanied by net neutrality regulations. For yet another year, this won't come from Congress, which is the only permanent solution. more
There was a recent article in the Bangor Daily News about Charter Communications fighting a move by small towns in Maine to bring fiber broadband. To anybody who has been in the business for a while, this is nothing new. The big cable companies and telcos have fought municipal broadband for decades. The article highlights a recent public meeting in the small town of Leeds, a town of under 2,300. The town was hoping to partner with Axiom Technologies, a nearby ISP, to provide fiber broadband. more
Last year I wrote about big disruptive outages on the T-Mobile and the CenturyLink networks. Those outages demonstrate how a single circuit failure on a transport route or a single software error in a data center can spread quickly and cause big outages. I join a lot of the industry in blaming the spread of these outages on the concentration and centralization of networks where the nationwide routing of big networks is now controlled by only a handful of technicians in a few locations. In early October, we saw the granddaddy of all network outages... more
Sanjay Bhargava, Starlink Country Director for India at SpaceX (source)SpaceX Starlink is moving quickly in India. Last April, they said they would be offering service in 2022 and began accepting pre-orders. In July, SpaceX committed to manufacturing antenna systems and terminals in India and, at the end of September, Sanjay Bhargava, who had been with Elon Musk at Paypal, was selected to head Starlink in India. In the last week or two, they set up a wholly-owned subsidiary that will apply for licenses, seek Indian distribution partners, and attempt to sell 200,000 units - 80% in rural districts - in 2022. more
I've been giving a lot of thought lately to the long-term trajectory of broadband prices. This is something that should be considered by anybody who is thinking about competing in a market against a big cable company. It's not an easy question to get your hands around since many factors might affect future rates. The following are some of the major trends that I think must be considered. First is pressure on the big ISPs from Wall Street. more
For those who follow the issue of blocking illegal content from the Internet, there is an interesting development in relation to this issue here in Germany, and I will tell you a little about it. One way to make it difficult to access illegal content is to block it directly in the DNS. But what is DNS for? Basically, it serves to translate the domain name into the IP of the server that is hosting the content. By blocking directly at the DNS level, a query to a domain will no longer bring the server's IP number, and with that, the user no longer accesses that content. more
Almost everybody in the broadband industry is now aware that the industry is suffering supply chain issues. ISPs are having problems obtaining many of the components needed to build a fiber network in a timely manner, which is causing havoc with fiber construction projects. I've been doing a lot of investigation into supply chain issues, and it turns out the supply chain is a lot more complex than I ever suspected, which means it's not going to be easy to get the supply chain back to normal. more
People ask me a lot about what Starlink means for somebody building a rural broadband network. That set me to contemplate the long-term prospects for LEO satellite broadband. Today, the broadband provided by Starlink is a boon to rural subscribers who have had no alternatives. Hundreds of thousands of prospective customers have gotten onto the Starlink waiting list. It's not hard to understand why when the rural broadband alternatives are extraordinarily slow rural DSL, high orbit satellite broadband, or cellular hotspots. more
