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.

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.

WiFi QoE Assurance with TR-069 - Part 2: Optimizing a Single Access Point

As we have seen in the first installment of this series, TR-069 offers unprecedented visibility into the customer premises network to highlight devices beyond the gateway, and in the case of WiFi, the issues affecting service quality. Insights into the surrounding WIFI landscape alone provide ample data to provision the access point (AP) to operate in a part of the spectrum with the least amount of interference.

How the Clinton “Village” Transformed Internet Paradigms: Together Making a Difference

U.S. Presidential elections and the resulting Administrations can make an enormous difference on many levels and become profound points of inflection. This reality is certainly starkly visible today. Perhaps for the Internet community as well as the general public, some of the largely unknown events and actions surrounding the Internet and the Clinton team from 25 years ago can provide a basis for engagement over the coming months.

Hyperconvergence, Disaggregation, and Cloud: The Foggy Future of Network Engineering

The world of networking tends to be bistable: we either centralize everything, or we decentralize everything. We started with mainframes, passed through Lotus 123 hidden in corners, then to mini's and middleware, then to laptops, and now to the cloud, to be followed by fog. This particular cycle of centralization/decentralization, however, has produced a series of overlapping changes that are difficult to decipher. You can somehow hear someone arguing about disaggregation and hyperconvergence through the fog -- but just barely.

The Next Development in Wireless Broadband

In the USA the FCC has started the discussion on the next level of telecoms in the wireless market, aimed at making spectrum in bands above 24GHz available for flexible-use of wireless services, including next-generation, or 5G networks and technologies. New technologies such as massive-MIMO are going to make it possible to deliver 'fibre-like' speeds over short distance wireless networks operating in the 24+GHz bands. This will make the technology especially useful for high-speed broadband services in densely populated areas.

Fibre Optic Technologies for the Next 50 Years

It might be hard to imagine but we were already talking about fibre to the home networks back in the 1970s and 1980s. This was in the early days of interactive TV and pay TV and fibre optics were already at that time seen as the next level of telecoms infrastructure needed for such services. The first residential fibre pilot networks were built in Berlin and Nagasaki. One of the most ambitious projects was in Columbus Ohio, but in the end they decided to continue with their HFC network.

Open Internet Access on the Line in Brussels

This summer EU regulators are finalizing their guidelines for member states on legal protections for wired, wireless and mobile open Internet access service. European citizens, businesses and NGOs have one last chance to make their voices heard on the so-called "net neutrality" guidelines by writing a comment for Body of European Regulators of Electronic Communications (BEREC) by July 18.

Is There a Positive Business Case for IPv6? We Are About to Find Out, If You Help Us…

Large-scale IPv6 deployments suggest that IPv6 is at least a technical success, the technology works. Time to visit the other important question: does it work commercially. Does IPv6 really come with a positive business case? We are about to find out, if you help us... The Internet technical community has spent about two decades making IPv6 work on a technical level. We have developed the protocol, modified and expanded a few others; we set up the registry system and distributed the addresses.

Analysis of the Global Telecoms Industry In 2016

The telecoms industry represents one of the most dynamic sectors in the world. Only 25 years ago 90% of all activities took place via telephone calls over fixed telephone lines. Now, within the broader ICT industry, telecoms is underpinning all of the new developments in relation to the digital, sharing and interconnected economies. It facilitates new social and economic developments in all sectors such as e-health, e-education, e-business, smart grids, smart cities, e-government, and so on.
