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

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 provides a possible answer to that question. 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
