Three Generations of Cuban WiFi Hotspot Sharing

As soon as ETECSA began installing public access WiFi hotspots, black market resellers began sharing connections. They would connect a laptop to an ETECSA account then use pirated copies of Connectify, a connection sharing program running on the laptop, to create small WiFi hotspots of their own. At the time, ETECSA charged 2 CUC per hour online (two day's pay for many Cubans) and the re-sellers typically charged 1 CUC per hour. They broke even with two users and made a profit with more. more

Two Approaches to Routers in Space: SpaceX and OneWeb

Two companies hope to revolutionize the Internet by providing global connectivity using constellations of low-earth orbit satellites -- Elon Musk's SpaceX and Greg Wyler's OneWeb. It seems that SpaceX gets a lot more publicity than OneWeb, but both are formidable... SpaceX is integrated -- building the rockets, satellites and ground stations themselves -- while OneWeb has a number of collaborators and investors, including Bharti Enterprises, Coca-Cola, Intelsat, Hughes, Totalplay Telecommunications, Virgin Galactic and Softbank. more

There Is No Cuban Home Internet Plan - And That’s Good News

I've followed Cuba's home-connectivity "plan" from the time it was leaked in 2015 until the recent Havana home Internet trial. I thought the plan was a bad idea when it was leaked -- it calls for installation of obsolete DSL (digital subscriber line) technology -- and now that the Havana trial is complete, I question whether the plan was real. ETECSA denied the validity of the leaked presentation at the time, and their definition of "broadband" was "at least 256 kb/s." more

Is Nokia’s New Framework Announcement Bringing Us Closer to Truly Smart Cities?

Nokia has developed a framework that will enable governments to implement smart cities. The framework is designed to aid regions to design and obtain services for smart city concepts. However, Nokia states that more emphasis needs to be put on developing an overarching strategy rather than small projects. The Australian government announced that they are interested in building smart cities, but there are still major gaps in figuring out how to do so. more

Interpol’s Michael Moran Receives 2017 M3AAWG Litynski Award

Michael "Mick" Moran, who has helped rescue thousands of child abuse material victims since he started working in the field in 1997, challenged the internet industry to do more to protect innocent children as he received the 2017 M3AAWG Mary Litynski Award. more

Keys to Successful Collaboration and Solving Wicked Internet Problems

The incredible pace of change of the Internet -- from research laboratory inception to global telecommunication necessity -- is due to the continuing pursuit, development and deployment of technology and practices adopted to make the Internet better. This has required continuous attention to a wide variety of problems ranging from "simple" to so-called "wicked problems". Problems in the latter category have been addressed through collaboration. This post outlines key characteristics of successful collaboration activities. more

Mitigating the Increasing Risks of an Insecure Internet of Things

The emergence and proliferation of Internet of Things (IoT) devices on industrial, enterprise, and home networks brings with it unprecedented risk. The potential magnitude of this risk was made concrete in October 2016, when insecure Internet-connected cameras launched a distributed denial of service (DDoS) attack on Dyn, a provider of DNS service for many large online service providers (e.g., Twitter, Reddit). Although this incident caused large-scale disruption, it is noteworthy that the attack involved only a few hundred thousand endpoints... more

Do-It-Yourself Rural Fiber

Necessity has led Cubans to become do-it yourself (DIY) inventors -- keeping old cars running, building strange, motorized bicycles, etc. They've also created DIY information technology like software, El Paquete Semanal, street nets and WiFi hotspot workarounds. Last June the International Telecommunication Union (ITU) adopted a standard for "low-cost sustainable telecommunications infrastructure for rural communications in developing countries," L.1700. L.1700 cable should be of interest to both DIY technologists and ETECSA. more

Notes from NANOG 69

NANOG 69 was held in Washington DC in early February. Here are my notes from the meeting. It would not be Washington without a keynote opening talk about the broader political landscape, and NANOG certainly ticked this box with a talk on international politics and cyberspace. I did learn a new term, "kinetic warfare," though I'm not sure if I will ever have an opportunity to use it again! more

NFV Orchestration Without Network Visibility: OS MANO Needs Operational Improvements

Open Source (OS) Management and Orchestrations (MANO) is a European Telecommunications Standards Institute (ETSI) initiative that aims to develop a Network Function Virtualization (NFV) MANO software stack, aligned with ETSI NFV. The main goal of MANO is to simplify the onboarding of virtual network components in telco cloud data centers. The initiative has gained impressive momentum among leading Communication Service Providers (CSPs) around the world as part of their NFV programs. more

China’s First IPv6-Only Backbone Network Connecting 1,200 More Campuses

2016 marked the start of the third and final phase of the China Next Generation Internet (CNGI) IPv6 program. more

Kill the Spreadsheets! Automate VPN IP Assignments and Tracking over MPLS/VRF and vLAN

Advancements in virtual private networking have extended system capabilities for service providers. Providers can divide LANs into multiple discrete segments using either Virtual Local Area Networks (vLANs), leverage Multiprotocol Label Switching (MPLS) or Virtual Routing and Forwarding (VRF) to host Virtual Private Networks (VPNs) that support service operations over multiple instances. more

Critical Differences Of Public And Private Clouds

Private or public? Both cloud types offer benefits and both have enjoyed significant growth over the last few years. Yet, what's the best bet for your business: The virtually limitless resources of public cloud stacks, or the close-to-home control of private alternatives? Here's a look at some critical differences between public and private clouds... more

Data Breaches Reported During 2016 Exposed Over 4.2 Billion Records

2016 broke the previous all-time high, set back in 2013, for the number of records exposed from reported data breaches. more

Dispersing a DDoS: Initial Thoughts on DDoS Protection

Distributed Denial of Service is a big deal -- huge pools of Internet of Things (IoT) devices, such as security cameras, are compromised by botnets and being used for large scale DDoS attacks. What are the tools in hand to fend these attacks off? The first misconception is that you can actually fend off a DDoS attack. There is no magical tool you can deploy that will allow you to go to sleep every night thinking, "tonight my network will not be impacted by a DDoS attack." more
