Automation for Physical Devices: the Holy Grail of Service Provisioning

Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) are finally starting to pick up momentum. In the process, it is becoming clear that they are not the silver bullet originally advertised to be. While great for some use cases, emerging technologies like SDN and NFV have been primarily designed for virtual greenfield environments. Yet large service providers continue to run tons of physical network devices that are still managed manually. more

Software-Defined Networking: What's New, and What's New for Tech Policy?

The Silicon Flatirons Conference on Regulating Computing and Code is taking place in Boulder. The annual conference addresses a range of issues at the intersection of technology and policy and provides an excellent look ahead to the tech policy issues on the horizon, particularly in telecommunications. I was looking forward to yesterday's panel on "The Triumph of Software and Software-Defined Networks", which had some good discussion on the ongoing problem surrounding security and privacy of the Internet of Things (IoT)... more

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

A Look Back at the World of IP Addressing in 2017: What Changed and What to Expect

There is no doubt that the Internet continues to grow. While the sales volumes of the more traditional forms of personal computers has peaked at some 430 million units per year and sales of handheld smart devices has also peaked at some 1.9 billion units per year, the world of the Internet of Things continues to spiral upward. The installed base of these "things" is now at an astonishing 8.4 billion at the end of 2017. more

Extraterritoriality

Black's Law Dictionary defines it as "the extraterritorial operation of laws; that is, their operation upon persons, rights or jural relations, existing beyond the limits of the enacting state, but still amenable to its laws. The term is used to indicate jurisdiction exercised by a nation in other countries, by treaty..." Extraterritoriality is also the most significant emerging development today in the law shaping virtual network architectures and services that includes OTT and NFV-SDN. 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

What is the Future for Mobile Network Operators?

The telecommunication industry is continuing to resist structural changes, but the reality is that if they don't transform, technology will do it for them. We have seen the fixed telecom operators slowly being pushed back into the infrastructure utility market. Mobile networks are moving in that same direction - that is, the largest part of their network will be a utility, with currently two, three or four mobile infrastructure providers per country... the industry is facing serious problems. 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
