Rough Guide to IETF 101: Internet of Things

The Internet of Things (IoT) is an increasingly hot buzzword around the Internet industry and the broader technology and innovation business arenas. We are often asked what the IETF is doing in relation to IoT and in this short Rough Guide to IETF 101 post I’d like to highlight some of the relevant sessions scheduled during the upcoming IETF 101 meeting in London. Also check out the IETF Journal IoT Category, the IETF IoT page, the IETF IoT Directorate, the Internet Society’s IoT page, or the Online Trust Alliance IoT page for more details about many of these topics. See also this recent article in the IETF Journal: Internet of Things: Standards and Guidance from the IETF.

The IETF Hackathon, held the weekend preceding the main IETF meeting (17-18 March), will include at least four projects directly related to IoT, with the possibility of more being added. More information is on the Hackathon wiki.

• Firmware Updates for Internet of Things
• Semantic Interoperability (WISHI – Workshop on IoT Semantic/Hypermedia Interoperability) Test Event
• 6LoRITT: 6LoWPAN Interoperability Testing Sessions (plugtest) with the F-Interop Testing Platform
• Measuring leakage from IoT with a MITM (“man in the middle”) proxy

Worth Reading: Drilling down into the Ethernet switching market

Cisco has always bragged that it doesn’t play in markets where it doesn’t command a 65 percent market share and a 65 percent operating margin, but you won’t hear the new top brass at Cisco saying that. The reason is simple: That ain’t ever gonna happen again. —Timothy Prickett Morgan @The Next Platform

Video Series: Modernizing Java Apps for Developers Part 1

Moving a monolithic application to a modern cloud architecture can be difficult and often result in a greenfield development effort. However, it is possible to move towards a cloud architecture using Docker Enterprise Edition with no code changes and gain portability, security and efficiency in the process.

Containerizing a monolithic application is a great starting point for modernizing application architecture.In many cases this can be done with no code changes at all.  From there, breaking down the application into smaller components makes it easier to deploy updates, introduce new components and manage scale.

This new video series covers modernization for Java applications. It walks through the process of evolving a N-tier Java application to a distributed application running across multiple containers. Docker provides the platform that plugs in and manages all the components into a coherent architecture.

This  series does not cover a full re-architecture to microservices. Shifting to a full microservices approach isn’t right for all applications, and the daunting task of a full rewrite of a monolithic application can be a massive endeavor that takes years to pay-off. Especially if what you have works. This series uses a feature driven approach. I select key features to update, in order to fix Continue reading

Low Latency Networking

Low latency is coming to a network near you. In fact, it’s probably coming to your network, whether or not you realize it.

While bandwidth has always been the primary measure of a network, and cross sectional or non-contending bandwidth for data center fabrics, further research and reflection has taught large scale network operators that latency is actually much more of a killer for application performance than lack of bandwidth—and not only latency, but its close cousin, jitter. Why is this?

To understand, it is useful to return to an example given by Tanenbaum in his book Computer Networks. He includes a humorous example of calculating the bandwidth of a station wagon full of VHS tapes, with each tape containing the maximum amount of data possible. For those young folks out there who didn’t understand a single word in that last sentence, think of an overnight delivery box from your favorite shipping service. Now stuff the box full of high density solid state storage of some kind, and ship it. You can calculate the bandwidth of the box by multiplying the number of devices you can stuff in there by the capacity of each device, and then dividing by roughly Continue reading

Deprecating TLS 1.0 and 1.1 on api.cloudflare.com

On June 4, Cloudflare will be dropping support for TLS 1.0 and 1.1 on api.cloudflare.com. Additionally, the dashboard will be moved from www.cloudflare.com/a to dash.cloudflare.com and will require a browser that supports TLS 1.2 or higher.

No changes will be made to customer traffic that is proxied through our network, though you may decide to enforce a minimum version for your own traffic. We will soon expose TLS analytics that indicate the percent of connections to your sites using TLS 1.0-1.3, and controls to set a specific minimum version. Currently, you may enforce version 1.2 or higher using the Require Modern TLS setting.

Prior to June 4, API calls made with TLS 1.0 or 1.1 will have warning messages inserted into responses and dashboard users will see a banner encouraging you to upgrade your browser. Additional details on these changes, and a complete schedule of planned events can be found in the timeline below.

Background

Transport Layer Security (TLS) is the protocol used on the web today to encrypt HTTPS connections. Version 1.0 was standardized almost 20 years ago as the successor to SSL Continue reading

GETTING STARTED: UPGRADING ANSIBLE TOWER

Thanks for checking out the Getting Started series! This quick tutorial lists the basic steps needed to perform an upgrade of Red Hat Ansible Tower in a standalone configuration. Specifically, we'll be upgrading Ansible Tower 3.1.0 to the latest (as of this writing) version 3.2.2 in a few simple steps. There are some things you’ll need to keep in mind while upgrading (e.g., editing the inventory file appropriately), and a description will be offered with each example.

Upgrading is Easy

The steps to upgrading are similar to installing Ansible Tower. The original inventory file from the install should already have the hostnames and variables you'll be using, so it's suggested that you work from your current install's inventory file to populate the upgrade file.

Your older inventory file may have some different lines than the newer upgrade version, due to updated configuration options or added features. In this example, the difference between the 3.1.0 and the 3.2.2 inventory files is the added ability to enable isolated key generation for clustered installs. See below for a side-by-side comparison: 

Space To Think My Own Thoughts

Everyone Creates

A challenge for people who make things is living in a world where everyone else makes things, too. On the Internet, everyone seems to be making something they want you to consider and approve of.

Sometimes, that Internet creation is as simple as a tweet or Facebook post. Like it! Share it! Retweet it! More complex creations, like this blog post, are still easy enough to make and share that there are likely hundreds of new articles you might be asked to read in a week.

If you were to carefully keep up with everything you subscribe to or follow, your mind would never have time to itself. You’d never be able to think your own thoughts. You’d be too busy chewing on the thoughts of other people.

Overconsumption

For this reason, I believe constant consumption damages productivity. Designers, architects, artisans, writers, and other creators need time to think through what they are making. Writers need a subject and word flow to clearly communicate. Technology architects need to deeply consider the implications of their designs from multiple angles.

Deep consideration takes contiguous blocks of time. Achieving a flowing state of mind takes uninterrupted time. Thoughts build one on Continue reading

FPGA Interconnect Boosted In Concert With Compute

To keep their niche in computing, field programmable gate arrays not only need to stay on the cutting edge of chip manufacturing processes. They also have to include the most advanced networking to balance out that compute, rivalling that which the makers of switch ASICs provide in their chips.

By comparison, CPUs have it easy. They don’t have the serializer/deserializer (SerDes) circuits that switch chips have as the foundation of their switch fabric. Rather, they might have a couple of integrated Ethernet network interface controllers embedded on the die, maybe running at 1 Gb/sec or 10 Gb/sec, and they offload …
