What should IETF “standard track” actually mean?

This post is going to be a little off the beaten path, but it might yet be useful for folks interested in the process of standardization through the IETF.

Last week, at the IETF in Buenos Aires, a proposal was put forward to move the IPv4 specifications to historic status. Geoff Huston, in his ISP column, points out the problem with this sort of thing—

As one commenter in the Working Group session pointed out, declaring IPv4 “Historic” would likely backfire and serve no better purpose other than exposing the IETF to ridicule. And certainly there is some merit in wondering why a standards body would take a protocol specification used by over 3 billion people, and by some estimated 10 billion devices each and every day and declare it to be “Historic”. In any other context such adoption figures for a technology would conventionally be called “outstandingly successful”!

The idea to push IPv4 to historic is, apparently, an attempt to move the market, in a sense. If it’s historic, then the market won’t use it, or will at least move away from it.

Right.

Micron Enlists Allies For Datacenter Flash Assault

If component suppliers want to win deals at hyperscalers and cloud builders, they have to be proactive. They can’t just sit around and wait for the OEMs and ODMs to pick their stuff like a popularity contest. They have to engineer great products with performance and then do what it takes on price, power, and packaging to win deals.

This is why memory maker Micron Technology is ramping up its efforts to get its DRAM and flash products into the systems that these companies buy, and why it is also creating a set of “architected solutions” focused on storage that …

IDG Contributor Network: Scaling out cloud apps still a challenge despite multi-core CPU advancements

Despite recent advancements and improved parallelism in multi-core CPU performance, there is still a big challenge to be solved relating to the scale-out of cloud applications.Put simply, Linux application performance scales poorly as CPU core count increases. This is commonly experienced as typical Linux applications can be expected to see a 1.5X performance improvement for a 2-core CPU, but the scale quickly plateaus after that, with 4 core performance only improving around 2.5X. The performance further degrades as core counts rise. Given that, along with Intel’s announcement that its Xeon chips have up to 22 cores, scaling performance efficiently across cores is extremely important.To read this article in full or to leave a comment, please click here

IRS security is failing taxpayers, senator says

The U.S. Internal Revenue Service, the Congress, and private electronic tax-filing vendors aren't doing enough to protect the personal information of taxpayers, senators said Tuesday.The IRS needs to step up its cyberecurity efforts, said members of the Senate Finance Committee, citing two recent data breaches at the agency, along with 94 open cybersecurity recommendations from the Government Accountability Office."Hackers and crooks, including many working for foreign crime syndicates, are jumping at every opportunity they have to steal hard-earned money and sensitive personal data from U.S. taxpayers," Senator Ron Wyden, an Oregon Democrat, said during a hearing. "In my view, taxpayers have been failed by the agencies, the companies, and the policymakers here in Congress they rely on to protect them."To read this article in full or to leave a comment, please click here

IDG Contributor Network: Sisense wants to make every user a data scientist

Analytics seems to be like the pot of gold at the end of the rainbow—hugely valuable but generally difficult (or impossible) to reach. It was always too hard, too slow, too expensive and too technical to be used on a widespread basis.Then things started to change. The rise of APIs meant that getting data into and out of core solutions became easier. The advent of cloud computing meant that standing up infrastructure on a short-term basis was easier, and a bunch of new approaches helped to make things far easier. One of the biggest proponents of this new way of driving analytics out to the business users is SAP, who is pushing hard for its HANA in-memory analytics service.To read this article in full or to leave a comment, please click here

The HTC 10 campaigns for the title best smartphone of 2016

HTC announced the HTC 10 premium smartphone today—its entry into the extreme competition for best smartphone on the planet. The device belongs to a category that makes no compromises in exterior presentation and interior performance. Trade-offs are a luxury enjoyed by makers of commodity smartphone models that pragmatic consumers buy.HTC earned its reputation by designing exquisite phones that others in the industry, including Apple, had to follow and sometimes copy. Most notably the iPhone 6 and 6s product lines look like HTC designs. Powered by a Qualcomm 820 SoC, the HTC 10 will be one of the fastest phones available. However, raw speed is its least-important feature because almost every smartphone is fast, to such an extent that the performance increase of the newest phones compared to last year’s is barely perceptible.To read this article in full or to leave a comment, please click here

The Gig Economy Breaks Social Security

With the tax deadline looming in the US and the future of the gig economy as the engine of scaling startup workforces under fire, there's an important point to consider: In the gig economy the entire social contract is kaput. Here's why.

Everyone who works in the US pays into the Social Security system. The whole idea of Social Security is young people pay in and old people take out.

When you are an employee Social Security taxes are taken directly out of your paycheck. You don't even have to think about it.

When you work in the gig economy you get a 1099-MISC at the end of the year. A 1099 reports payments made by the hiring company during the year and it's sent by the hiring company both to the worker and the IRS.

It's up to the worker to identify their income on their tax return as self employment income, which is subject to a Social Security tax of 15.3%. Most gig workers probably won't declare this income because a lot of them don't even know they are supposed to. My wife, Linda Coleman, a respected Enrolled Agent, says from people she has talked to Continue reading

Docker Container Network Types

Docker provides similar network connection options as general virtualization solutions such as VMware products, Hyper-V, KVM, Xen, VirtualBox, etc. However, Docker takes a slightly different approach with its network drivers, confusing new users which are familiar with general terms used by other virtualization products. The following table matches general terms with Docker network drivers you can use to achieve the same type of connectivity for your container.

General Virtualization Term Docker Network Driver
NAT Network bridge
Bridged macvlan, ipvlan (experimental since Docker 1.11)
Private / Host-only bridge
Overlay Network / VXLAN overlay

Most Powerful (Whatever) From A to Z

At least according to Google Chrome AutocompleteHaving long found Google Chrome’s Autocomplete feature useful, the thought was to have a little fun by combining its predictive capabilities with journalism’s “Most Powerful (Whatever)” list format by typing into the search box “Most powerful a” … “Most powerful b” … and on through the alphabet to “Most powerful z.” The results, primarily a byproduct of the public’s frequency of searching on those terms, are a mixture of what you might expect and some real head-scratchers. (Note: The slide images were created by one of our designers using a newly downloaded version of Chrome, so your mileage may vary.)To read this article in full or to leave a comment, please click here

IPv6 and the Internet of Things

It has often been claimed that IPv6 and the Internet of Things are strongly aligned, to the extent that claims are made they mutually dependant. Each needs the other. However, the evidence we have so far with small self-managed device deployments does not provide a compelling justification of this case. The question here is: Does the Internet of Things require IPv6 as an essential precondition, or are we going to continue to deploy an ever expanding population of micro devices within today’s framework of ever increasing address sharing on IPv4?

IS-IS LiveLesson Publishing Soon

is-is-livelessonWhile the IS-IS book is still useful, it is getting on a little in age, and some people find learning through video to be more helpful. I’ve recorded seven hours of video on IS-IS in the form of a LiveLesson with Cisco Press. They should be available on the 18th of April (just a few days from now), and apparently they’re already available as a sneak peek.

Thanks to Brett (who runs, and has run, all my projects at Cisco Press and Addison-Wesley), Pete (who patiently recorded my many fumbles), and Chris Cleveland, who has been my steadfast editor for all things Cisco Press and Addison-Wesley for some fifteen years now), for making this happen. This is the first, I think, of a number of new video projects I have on tap, so watch this space.

And no, I’m not going to stop writing books (just a gentle reminder).

Lasers!

Cool! You mean that I actually have frickin' switches with frickin' laser beams attached to their frickin' ports?

Dr. Evil is right, lasers are cool! The draft sFlow Optical Interface Structures specification exports metrics gathered from instrumentation built into Small Form-factor Pluggable (SFP) and Quad Small Form-factor Pluggable (QSFP) optics modules. This article provides some background on optical modules and discusses the value of including optical metrics in the sFlow telemetry stream exported from switches and hosts.
Pluggable optical modules are intelligent devices that do more than simply convert between optical and electrical signals. The functional diagram below shows the elements within a pluggable optical module.
The transmit and receive functions are shown in the upper half of the diagram. Incoming optical signals are received on a fiber and amplified as they are converted to electrical signals that can be handled by the switch. Transmit data drives the modulation of a laser diode which transmits the optical signal down a fiber.

The bottom half of the diagram shows the management components. Power, voltage and temperature sensors are monitored and the results are written into registers in an EEPROM that are accessible via a management interface.

The proposed sFlow extension standardizes Continue reading
