Streaming Telemetry Standards: So Many to Choose From
Continuing the Streaming Telemetry saga, let’s focus on presentation formats and transport mechanisms.
I already mentioned three presentation formats: XML (used by NETCONF), JSON (used by RESTCONF) and Protocol Buffers (used by gRPC). Two of them are text-based, the third one (Protocol Buffers) is binary encoding not unlike ASN.1 BER used by SNMP. That can’t be good in a JSON-hyped world, right?

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

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
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
