Six Years After: State of IPv6 Deployment 2018

On the sixth anniversary of World IPv6 Launch, we’re sharing an updated report on the State of IPv6 Deployment in 2018. It really is staggering how far IPv6 deployment has progressed in six years. In mid-2012, Google measured less than 1% of users accessing their services over IPv6. Today that figure is getting close to 25%. Several major operators now deliver the majority of traffic from major content sources like Google, Akamai and Facebook over IPv6. Individual operators, like T-Mobile USA, have deployed IPv6-only networks for their subscribers.

Seven years ago, the Internet Society helped to organize World IPv6 Day, where thousands of ISPs and websites joined together for a successful, global-scale, 24-hour trial of IPv6. A year later, for World IPv6 Launch, major ISPs, home networking equipment manufacturers, and web companies around the world permanently enabled IPv6 for their products and services.

To help showcase the progress made in the six years since World IPv6 Launch we are sharing:

– an updated report on the State of IPv6 Deployment 2018
– an infographic that clearly shows the scale and scope of IPv6 deployment
– and a fun quiz for you to test and share your knowledge of the Continue reading

You’re probably doing your IIoT implementation wrong

The Industrial internet of things promises a quantum leap forward in automation, centralized management and a wealth of new data and insight that is often too tempting to pass up. But automating a factory floor or a fleet of vehicles is far from simple, and many would-be IIoT adopters are going about the process all wrong, according to experts.To make an IIoT transition a success, the process has to be led by the line-of-business side of the company – not IT. Successful IIoT adopters frame the entire operation as a matter of digital transformation, aimed at addressing specific business problems, rather than as a fun challenge for IT architects to solve.To read this article in full, please click here

6 years on, IPv4 still dominates IPv6

IPv6, the modern version of the Internet Protocol framework that underlies just about everything on the network, is seeing steady uptake among service providers, but still hasn’t pushed its predecessor, IPv4, into obsolescence, according to a report released today by the Internet Society.There are 24 countries in the world where IPv6 totals more than 15% of overall IP traffic, and 49 that have topped the 5% threshold. Yet the Internet Society – a non-profit that works to promulgate internet standards and lobby for open access to the internet – describes the technology as having moved from the “early adoption” development stage to the “early majority” phase.To read this article in full, please click here

Automation Win: Document Cisco ACI Configuration

This blog post was initially sent to the subscribers of my SDN and Network Automation mailing list. Subscribe here.

A while ago I complained how the GUI- or API-based orchestration (or intent-based) systems make it hard to figure out what exactly has been configured because they can’t give you a single text configuration file that you could track with version-control software.

Dirk Feldhaus found the situation so ridiculous that he decided to create an Ansible playbook that collects and dumps tenant parameters configured on a Cisco ACI tenant as a homework assignment in the Building Network Automation Solutions online course. As he explained the problem:

Reducing DRAM footprint with NVM in Facebook

Reducing DRAM footprint with NVM in Facebook Eisenman et al., EuroSys’18

(If you don’t have ACM Digital Library access, the paper can be accessed either by following the link above directly from The Morning Paper blog site).

…to the best of our knowledge, this is the first study on the usage of NVM devices in a commercial data center environment.

We’ve been watching NVM coming for some time now, so it’s exciting to see a paper describing its adoption within Facebook. MyRocks is Facebook’s primary MySQL database, and is used to store petabytes of data and to serve real-time user activities. MyRocks uses RocksDB as the storage engine, and a typical server consumes 128GB of DRAM and 3 TB of flash. It all seems to work well, so what’s the problem? Spiralling costs!

As DRAM facing major scaling challenges, its bit supply growth rate has experienced a historic low. Together with the growing demand for DRAM, these trends have led to problems in global supply, increasing total cost of ownership (TCO) for data center providers. Over the last year, for example, the average DRAM DDR4 price has increased by 2.3x.

Just using less DRAM per server Continue reading

G7 Leaders, the World is looking at you to make the right decisions

As Canadian Prime Minister Justin Trudeau gets ready to host the G7 Summit this week, renewed tensions around trade remind us how vulnerable the global economy is, and how working together is more important than ever to solve these complex issues.

And today, the world is looking to G7 leaders to make the right decisions.

The connected future is here. While the Internet has yet to reach its full potential (half of the world’s population remains offline), there’s little doubt that it’s already changing the landscape of trade, jobs, and the digital economy. According to data from McKinsey, the Internet accounts on average for 3.4 % GDP across the large economies that make up 70 % of global GDP. The global network offers a unique space where data, goods and services can flow and fuel the next wave of global growth, where anyone can take part and benefit from new economic opportunities.

One of the values of this connected world is our ability to interconnect — the way we live our lives, the way we socialize, and we interact with the world. Everything from clothes to toys and toothbrushes are coming online as well. The International Data Continue reading

Reaction: The Power of Open APIs

Disaggregation, in the form of splitting network hardware from network software, is often touted as a way to save money (as if network engineering were primarily about saving money, rather than adding value—but this is a different soap box). The primary connections between disaggregation and saving money are the ability to deploy white boxes, and the ability to centralize the control plane to simplify the network (think software defined networks here—again, whether or not both of these are true as advertised is a different discussion).

But drivers that focus on cost miss more than half the picture. A better way to drive the value of disaggregation, and the larger value of networks within the larger network technology sphere, is through increased value. What drives value in network engineering? It’s often simplest to return to Tannenbaum’s example of the station wagon full of VHS backup tapes. To bring the example into more modern terms, it is difficult to beat the bandwidth of an overnight box full of USB thumb drives in terms of pure bandwidth.

In this view, networks can primarily be seen as a sop to human impatience. They are a way to get things done more quickly. In the Continue reading
