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

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

Google and the Future of FttH

Many commentators rushed into print when they heard that Craig Barratt, senior vice-president of Google's parent company Alphabet and CEO of Access (the unit of which Google Fiber is part), stated that he would quit the job and that Google would slow down or stop its fibre deployment. So, yes, obviously something is happening at Google; but at the same time, the company has a commitment to complete the fiber deployment projects it has already started and also to build the many new networks that have been announced over the last six months. more

How Can You Make More Accurate Capacity Planning Decisions?

Cable operators face a big challenge today as data utilization continues to increase on their networks. Keeping up with the demand for high quality services while upgrading network infrastructure seems to be a never-ending task. Many times, network upgrades are done without much help from tools and systems, leaving it mostly based on experience and performance indicators defined by the operator. Unfortunately, this is the reality for far too many service providers today. more

The Lean and Antifragile Data Centre

Cloud is a new technology domain, and data centre engineering is still a developing discipline. I have interviewed a top expert in cloud infrastructure, Pete Cladingbowl. He has a vision of the 'lean' data centre and a better kind of Internet for users to reach it. He also has a roadmap for how these can be practically realised. The key is to apply established theories of value flow from more mature industries. more

What’s Holding Back NFV Deployments?

Back in early 2012, the media was all over stack wars that reportedly were taking place between Cisco and VMware. This culminated in VMware's Nicira acquisition in July 2012, paving the way for the coming of software-based networking. Four years later, the market still remains in development mode. Many service providers and enterprises are trying to come to grips with Network Function Virtualization (NFV) and Software-Defined Networking (SDN). more

China’s QUESS and Quantum Communications

In mid-August China launched "QUESS" (Quantum Experiments at Space Scale), a new type of satellite that it hopes will be capable of "quantum communications" which is supposed to be hack-proof, through the use of "quantum entanglement". This allows the operator to ensure that no one else is listening to your communications by reliably distributing keys that are then used for encryption in order to be absolutely sure that there is no one in the middle intercepting that information. more

Complexity and Crashes

It's a familiar story by now: on the 8th of August, 2016, Delta lost power to its Atlanta data center, causing the entire data center to fail. Thousands of flights were cancelled, many more delayed, and tens of thousands of travellers stranded. What's so unusual about this event is in the larger scheme of network engineering, it's not that unusual. If I think back to my time on the Escalation Team at a large vendor, I can think of hundreds of situations like this. And among all those events, there is one point in common: it takes longer to boot the system than it does to fix the initial problem. more

IoT Developments: NIST Issues Tech Guidance while NTIA Seeks Broad Input, Global Efforts Percolate

As the federal government grapples with Internet-connected devices and applications that make up the Internet of Things (IoT), the National Institute of Standards and Technology (NIST) is forging ahead to provide "technical leadership" for "the operation, trustworthiness, and lifecycle of IoT". Such efforts complement - and contrast - recent policy efforts at the National Telecommunications and Information Administration (NTIA) and elsewhere to promote IoT innovation while addressing security, privacy, and interoperability.  more
