Networks - The Next Challenge in Digital Transformation

As digital transformation has been picking up momentum, leading analysts such as 451 Research have suggested that hybrid multi-clouds and automated DevOps will become key constituents powering enterprises in the new era. At the heart of these enabling technologies lies Lifecycle Service Orchestration (LSO) designed for near-autonomous application deployment across hybrid infrastructures consisting of traditional on-premise data centers and public clouds. more

The Future of Networking (In One Slide)

I recently ran a workshop in Asia and to guide attendees through the content; I put together an overview slide which you might also find of interest and use. It is a description of the quality attenuation framework, originally developed and defined by Predictable Network Solutions Ltd, and documented and extended by myself and colleagues at Just Right Networks Ltd. more

Shedding Light on How Much Energy the Internet and ICTs Consume

Ever since I published an essay exploring the relationship between climate change and the Internet, I have endeavored to bring this subject to the fore as often as possible (and in relevant fora and discussions) since the responsibility of creating a more sustainable world falls on all communities and stakeholder groups. It is particularly pressing now -- at a time when international interest in curbing climate change is strengthening, while it is juxtaposed with the receding commitments of the United States government... more

Network Dis-Aggregation and SDN: Different, But Related

Two of the hottest trends in networking today are network dis-aggregation and SDN. This is great for many reasons. It's also confusing. The marketing hype makes it hard to understand either topic. SDN has become so vague that if you ask 10 experts what it means, you are likely to get 12 different answers. Network dis-aggregation seems straightforward enough until it gets confused with SDN. We need to take a step back. In a recent Packet Pushers blog post; I start with a simple explanation of each of these trends and then map how they interact. more

Google Claims It Fixed the Security Holes the CIA Exploited

WikiLeaks shook the internet again on March 7, 2017, by posting several thousand documents containing information about the tools the CIA allegedly used to hack, among others, Android and iOS devices. These classified files were obtained from the CIA's Center for Cyber Intelligence, although they haven't yet been verified and a CIA official declined to comment on this incident. This isn't the first time that the U.S. government agencies were accused of crossing the line and undermining online security and civil liberties, as it's been only a year since the infamous FBI-Apple encryption dispute. It's like "1984" all over again. more

The Internet as Weapon

One of the most striking and enduring dichotomies in the conceptualization of electronic communication networks is summed up in the phrase "the Internet as weapon." With each passing day, it seems that the strident divergence plays in the press -- the latest being Tim's lament about his "web" vision being somehow perverted. The irony is that the three challenges he identified would have been better met if he had instead pursued a career at the Little Theatre of Geneva and let SGML proceed to be implemented on OSI internets rather than refactoring it as HTML to run on DARPA internets. more

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
