Nationalizing the Imaginary 5G Network?

To put it bluntly, the proposal cited in Axios story on "Trump team considers nationalizing 5G network" doesn't make sense on a number of levels. The real danger comes if this indeed represents the NSC's failure to understand Internet style connectivity. The proposal may just be the work of an NSC staffer who accepted all the 5G hype as if it were real. I credit the Axios article for having some skepticism... more

Wow, a U.S. Ministry of 5G

This seemed to be the reaction this morning worldwide to the leaked alleged PowerPoint slides detailing the White House strategic options for a U.S. national 5G infrastructure. The gist of the slides has apparently been confirmed to Reuters by unnamed "Trump security team members." The options apparently range between creating a U.S. Ministry of 5G resembling the old world of government Post, Telegraph and Telecommunication (PTT) agencies of bygone years, and sawing off the U.S. ICT infrastructures and services from the rest of the world. more

Industrial Plant Attack Generates Renewed Concerns Over Critical Infrastructure Hacking Threats

A recent malware attack on the control systems of an industrial plant has renewed concerns about the threat hacking poses to critical infrastructure. more

The Over-Optimization Meltdown

In simple terms, Meltdown and Spectre are simple vulnerabilities to understand. Imagine a gang of thieves waiting for a stage coach carrying a month's worth of payroll. There are two roads the coach could take, and a fork, or a branch, where the driver decides which one to take. The driver could take either one. What is the solution? Station robbers along both sides of the branch, and wait to see which one the driver chooses. more

A Year in Review: 14,000 Routing Incidents In 2017

How was the state of the Internet's routing system in 2017? Let's take a look back using data from BGPStream. Some highlights: 13,935 total incidents (either outages or attacks like route leaks and hijacks); Over 10% of all Autonomous Systems on the Internet were affected; 3,106 Autonomous Systems were a victim of at least one routing incident; 1,546 networks caused at least one incident. more

The Net Neutrality Reversal Order: Why the FCC Will Prevail

It is now out -- all 539 pages entitled "Declaratory Ruling, Report and Order, and Order" (Reversal Order). As someone who has dealt with this subject matter at a working level over the past 40+ years, it seems clear that the FCC will readily prevail here and the protagonists need to move on. (Admittedly that is wishful thinking given the appellate revenue to be made and press blather opportunities.) The document from a Federal Administrative Law perspective is very thorough and well-crafted. more

Do We Really Need a New BGP?

From time to time, I run across (yet another) article about why Border Gateway Protocol (BGP) is so bad, and how it needs to be replaced. This one, for instance, is a recent example. It seems the easiest way to solve this problem is finding new people - ones who don't make mistakes - to work on BGP configuration, building IRR databases, and deciding what should be included in BGP? more

Innovation Today is IN the Network

The largest and most important global information infrastructure today by any measure is clearly the global mobile network and all of its gateways, services, and connected devices. That network is standardized, managed, and energized by a combination of the 3GPP and GSMA. The level of 3GPP industry involvement and collaboration today probably exceeds all other telecom, internet, and assorted other bodies put together... and then some. more

Give Network Administrators a Zero-Impact Firmware Update Solution

Struggles with the firmware update process are well known by Network Administrators in the cable industry. The copious tasks required to complete an end-to-end firmware update are painstaking and error-prone, often making the investment not worth the time it takes to complete the work... imagine doing these manual tasks over and over for hundreds to thousands of devices, many from different vendors, each with its own unique device update path! Clearly, this complex challenge needs a solution. more

Could SNET Become Cuba’s Guifi.net?

In an earlier post, I described Havana's community network, SNET, and wondered what it could become if the government and ETECSA were willing to legitimatize and support it. Spain's Guifi.net provides a possible answer to that question. Guifi.net is said to be the largest community network in the world. It began in 2004 and has grown to have 34,165 nodes online with 16,758 planned, 407 building, 612 testing and 4,043 inactive. more

Data on Cuba’s SNET and a Few Suggestions for ETECSA

I've written several posts on Cuba's user-deployed street networks (SNET), the largest of which is SNET in Havana. (SNET was originally built by the gaming community, but the range of services has grown substantially). My posts and journalist's accounts like this one describe SNET, but a new paper presents SNET measurement data as well as descriptive material. more

Internet Hall of Fame Inductees Gather at GNTC to Discuss New Generation of Internet Infrastructure

Confronted with the rapid development of the Internet, the traditional network is facing severe challenges. Therefore, it is imperative to accelerate the construction of global network infrastructure and build a new generation of Internet infrastructure to adapt to the Internet of Everything and the intelligent society. From November 28 to 30, 2017, "GNTC 2017 Global Network Technology Conference" organized by BII Group and CFIEC, will see a grand opening in Beijing. more

Why Aren’t We Fixing Route Leaks?

In case you missed it (you probably didn't), the Internet was hit with the Monday blues this week. As operator-focused lists and blogs identified, "at 17:47:05 UTC yesterday (6 November 2017), Level 3 (AS3356) began globally announcing thousands of BGP routes that had been learned from customers and peers and that were intended to stay internal to Level 3. By doing so, internet traffic to large eyeball networks like Comcast and Bell Canada, as well as major content providers like Netflix, was mistakenly sent through Level 3's misconfigured routers." more

A Glance Back at the Looking Glass: Will IP Really Take Over the World?

In 2003, the world of network engineering was far different than it is today. For instance, EIGRP was still being implemented on the basis of its ability to support multi-protocol routing. SONET, and other optical technologies were just starting to come into their own, and all-optical switching was just beginning to be considered for large-scale deployment. What Hartley says of history holds true when looking back at what seems to be a former age: "The past is a foreign country; they do things differently there." more

Why 5G Is in Trouble (and How to Fix It)

I have a somewhat unconventional view of 5G. I just happen to believe it is the right one. It is trapped inside a category error about the nature of packet networking, and this means it is in trouble. As context, we are seeing the present broadband Internet access model maturing and begin to reach its peak. 5G eagerly anticipates the next wave of applications. As such, 5G is attempting to both extend and transcend the present "undifferentiated data sludge" model of mobile broadband. more
