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

Canadian Energy Firms at Bigger Risk of Cyberattack

The Canadian Security Intelligence Service (CSIS) is reported to have warned companies about an increasing risk of cyber espionage and attacks on pipelines, oil storage and shipment facilities. more

Zero-Touch Provisioning… Really?

Zero-touch provisioning (ZTP) -- whatever does that mean? Of course, it is another marketing term. I think the term "closer to zero touch provisioning" is probably better, but CTZTP -- as opposed to ZTP -- is a bit more of a mouthful. Whenever I hear language like this that I'm not familiar with, I get struck by a bolt of curiosity. What is this new and shiny phrase that has just appeared as if from nowhere? more

Over 50 Internet Shutdowns Reported in 2016

"Governments around the world shut down the internet more than 50 times in 2016 -- suppressing elections, slowing economies and limiting free speech," Lyndal Rowlands reporting in IPS. more

A Three Minute Guide to Network Automation Bliss

The cloud computing paradigm has been making steady progress in 2016. With the DevOps model making its way from cloud to networking, the business upside of fully automated service architectures is finally beginning to materialize. The associated service agility is expected to unleash new business models that transform the ways in which applications and connectivity can be consumed. more

Google Fiber in Havana - Wishful Thinking?

This post is conjecture, but it is informed conjecture... Consider the following: When Google Fiber started in Kansas City, most people assumed that it was a demonstration project, intended to spur investment by the incumbent US Internet service providers (ISPs). Few thought that Google wanted to become a retail ISP. Google Fiber garnered a lot of publicity and Google, began speaking of it as a real, profit-making business. They announced other cities and started laying fiber in some of them. more
